After the amount of flack Jon Toigo had to endure for not giving advanced notice to his upcoming Webcast, I thought I would better remind people about my own Webinar that is happening next Tuesday, August 23.
So here's the scoop, next Tuesday I will be presenting [The Future of Storage], August 23, 1pm to 2pm EDT. You can register to attend at the [Infoboom Registration Page]. Infoboom is a social community for business and IT leaders of small and midsize businesses brought to you by IBM.
But that's not all! After the webinar, I will then travel to various cities for face-to-face lectures. Here are the first two:
September 7 - Indianapolis
September 8 - Boston area
If you are near either of these two locations, contact your local IBM storage specialist or IBM business partner to participate.
The IBM Storwize V7000 was introduced last October, and has proven to be wildly successful. I saw two awesome reviews recently of the IBM Storwize V7000 disk system that I thought I would bring to your attention.
The first review is [IBM Storwize V7000] from Roger Howorth of ZDNet UK. Here are some quotes:
"Under the hood, the Storwize V7000 is built from technologies originally developed for IBM's enterprise-class storage systems, so the V7000 benefits from a comprehensive set of high-end features that have been scaled down for mid-range buyers."
"Initial configuration couldn't be simpler."
"We really liked the layout and functionality of the GUI."
"Storwize V7000 is virtual storage that offers efficiency and flexibility through built-in SSD optimization and "thin provisioning" technologies while enabling users to virtualize and re-use existing disk systems..."
"Storwize V7000 advanced functionality also enables non-disruptive migration of data from existing storage, simplifying implementation and minimizing disruption to users."
"The Storwize V7000 graphical user interface is a browser-based, easy to navigate intuitive GUI."
"ESG Lab found that getting started with the Storwize V7000 disk system was intuitive and straightforward."
"Easy Tier increases the efficiency and simplicity of deploying SSD drives."
Full VMware Vstorage API for Array Integration (VAAI). Back in 2008, VMware announced new vStorage APIs for its vSphere ESX hypervisor: vStorage API for Site Recovery Manager, vStorage API for Data Potection, vStorage API for Multipathing. Last July, VMware added a new API called vStorage API for Array Integration [VAAI] which offers three primitives:
Hardware-assisted Blocks zeroing. Sometimes referred to as "Write Same", this SCSI command will zero out a large section of blocks, presumably as part of a VMDK file. This can then be used to reclaim space on the XIV on thin-provisioned LUNs.
Hardware-assisted Copy. Make an XIV snapshot of data without any I/O on the server hardware.
Hardware-assisted locking. On mainframes, this is call Parallel Access Volumes (PAV). Instead of locking an entire LUN using standard SCSI reserve commands, this primitive allows an ESX host to lock just an individual block so as not to interfere with other hosts accessing other blocks on that same LUN.
Quality of Service (QoS) Performance Classes.
When XIV was first released, it treated all hosts and all data the same, even when deployed for a variety of different applications. This worked for some clients, such as [Medicare y Mucho Más]. They migrated their databases, file servers and email system from EMC CLARiiON to an IBM XIV Storage System. In conjunction with VMware, the XIV provides a highly flexible and scalable virtualized architecture, which enhances the company's business agility.
However, other clients were skeptical, and felt they needed additional "nobs" to prioritize different workloads. The new 10.2.4 microcode allows you to define four different "performance classes". This is like the door of a nightclub. All the regular people are waiting in a long line, but when a celebrity in a limo arrives, the bouncer unclips the cord, and lets the celebrity in. For each class, you provide IOPS and/or MB/sec targets, and the XIV manages to those goals. Performance classes are assigned to each host based on their value to the business.
Offline Initialization for Asynchronous Mirror.
Internally, we called this Truck Mode. Normally, when a customer decides to start using Asynchronous Mirror, they already have a lot of data at the primary location, and so there is a lot of data to send over to the new XIV box at the secondary location. This new feature allows the data to be dumped to tape at the primary location. Those tapes are shipped to the secondary location and restored on the empty XIV. The two XIV boxes are then connected for Asynchronous Mirroring, and checksums of each 64KB block are compared to determine what has changed at the primary during this "tape delivery time". This greatly reduces the time it takes for the two boxes to get past the initial synchronization phase.
IP-based Replication. When IBM first launched the Storwize V7000 last October, people commented that the one feature they felt missing was IP-based replication. Sure, we offered FCP-based replication as most other Enterprise-class disk systems offer today, but many midrange systems also offer IP-based repliation to reduce the need for expensive FCIP routers. [IBM Tivoli Storage FastBack for Storwize V7000] provides IP-based replication for Storwize V7000 systems.
Network Attached Storage
IBM announced two new models of the IBM System Storage N series. The midrange N6240 supports up to 600 drives, replacing the N6040 system. The entry-level N6210 supports up to 240 drives, and replaces the N3600 system. Details for both are available on the latest [data sheet].
IBM Real-Time Compression appliances work with all N series models to provide additional storage efficiency. Last October, I provided the [Product Name Decoder Ring] for the STN6500 and STN6800 models. The STN6500 supports 1 GbE ports, and the STN6800 supports 10GbE ports (or a mix of 10GbE and 1GbE, if you prefer). The IBM versions of these models were announced last December, but some people were on vacation and might have missed it. For more details of this, read the [Resources page], the [landing page], or [watch this video].
IBM System Storage DS3000 series
IBM System Storage [DS3524 Express DC and EXP3524 Express DC] models are powered with direct current (DC) rather than alternating current (AC). The DS3524 packs dual controllers and two dozen small-form factor (2.5 inch) drives in a compact 2U-high rack-optimized module. The EXP3524 provides addition disk capacity that can be attached to the DS3524 for expansion.
Large data centers, especially those in the Telecommunications Industry, receive AC from their power company, then store it in a large battery called an Uninterruptible Power Supply (UPS). For DC-powered equipment, they can run directly off this battery source, but for AC-powered equipment, the DC has to be converted back to AC, and some energy is lost in the conversion. Thus, having DC-powered equipment is more energy efficient, or "green", for the IT data center.
Whether you get the DC-powered or AC-powered models, both are NEBS-compliant and ETSI-compliant.
New Tape Drive Options for Autoloaders and Libraries
IBM System Storage [TS2900 Autoloader] is a compact 1U-high tape system that supports one LTO drive and up to 9 tape cartridges. The TS2900 can support either an LTO-3, LTO-4 or LTO-5 half-height drive.
IBM System Storage [TS3100 and TS3200 Tape Libraries] were also enhanced. The TS3100 can accomodate one full-height LTO drive, or two half-height drives, and hold up to 24 cartridges. The TS3200 offers twice as many drives and space for cartridges.
From New York, Rolf went to London, Paris, Madrid, Morocco, Cairo, South Africa, Bangkok Thailand, Malaysia, Singapore, New Zealand, Australia, and then back to United States. I was hoping to run into him while I was in Australia and New Zealand last month, but our schedules did not line up.
Travelingwithout baggage is more than just a convenience, it is a metaphor for the philosophy that we should keep only what we need, and leave behind what we don't. This was the approach taken by IBM in the design of the IBM Storwize V7000 midrange disk system.
The IBM Storwize V7000 disk system consists of 2U enclosures. Controller enclosures have dual-controllers and drives. Expansion enclosures have just drives. Enclosures can have either 24 smaller form factor (SFF) 2.5-inch drives, or twelve larger 3.5-inch drives. A controller enclosure can be connected up to nine expansion enclosures.
The drives are all connected via 6 Gbps SAS, and come in a variety of speeds and sizes: 300GB Solid-State Drive (SSD); 300GB/450GB/600GB high-speed 10K RPM; and 2TB low-speed 7200 RPM drives. The 12-bay enclosures can be intermixed with 24-bay enclosures on the same system, and within an enclosure different speeds and sizes can be intermixed. A half-rack system (20U) could hold as much as 480TB of raw disk capacity.
This new system, freshly designed entirely within IBM, competes directly against systems that carry a lot of baggage, including the HDS AMS, HP EVA, an EMC CLARiiON CX4 systems. Instead, we decided to keep the what we wanted from our other successful IBM products.
Inspired by our successful XIV storage system, IBM has developed a web-based GUI that focuses on ease-of-use. This GUI uses the latest HTML5 and dojo widgets to provide an incredible user experience.
Borrowed from our IBM DS8000 high-end disk systems, state-of-the-art device adapters provide 6 Gbps SAS connectivity with a variety of RAID levels: 0, 1, 5, 6, and 10.
From our SAN Volume Controller, the embedded [ SVC 6.1 firmware] provides all of the features and functions normally associated with enterprise-class systems, including Easy Tier sub-LUN automated tiering between Solid-State Drives and Spinning disk, thin provisioning, external disk virtualization, point-in-time FlashCopy, disk mirroring, built-in migration capability, and long-distance synchronous and asynchronous replication.
Finally, the various "internal NDA" that kept me from publishing this sooner have expired, so now I have the long-awaited [Inside System Storage: Volume II], documenting IBM's transformation in its storage strategy, including behind-the-scenes commentary about IBM's acquisitions of XIV and Diligent. Available initially in paperback form. I am still working on the hard cover and eBook editions.
For those who have not yet read my first book, Inside System Storage: Volume I, it is still available from my publisher Lulu, in [hard cover], [paperback] and [eBook] editions.
IBM System Storage DS8800
A lesson IBM learned long ago was not to make radical changes to high-end disk systems, as clients who run mission-critical applications are more concerned about reliability, availability and serviceability than they are performance or functionality. Shipping any product before it was ready meant painfully having to fix the problems in the field instead.
(EMC apparently is learning this same lesson now with their VMAX disk system. Their Engenuity code from Symmetrix DMX4 was ported over to new CLARiiON-based hardware. With several hundred boxes in the field, they have already racked up over 150 severity 1 problems, roughly half of these resulted in data loss or unavailability issues. For the sake of our mutual clients that have both IBM servers and EMC disk, I hope they get their act together soon.)
To avoid this, IBM made incremental changes to the successful design and architecture of its predecessors. The new DS8800 shares 85 percent of the stable microcode from the DS8700 system. Functions like Metro Mirror, Global Mirror, and Metro/Global Mirror, are compatible with all of the previous models of the DS8000 series, as well as previous models of the IBM Enterprise Storage Server (ESS) line.
The previous models of DS8000 series were designed to take in cold air from both front and back, and route the hot air out the top, known as chimney design. However, many companies are re-arranging their data centers into separate cold aisles and hot aisles. The new DS8800 has front-to-back cooling to help accommodate this design.
My colleague Curtis Neal would call the rest of this a "BFD" announcement, which of course stands for "Bigger, Faster and Denser". The new DS8800 scales-up to more drives than its DS8700 predecessor, and can scale-out from a single-frame 2-way system to a multi-frame 4-way system. IBM has upgraded to faster 5GHz POWER6+ processors, with dual-core 8 Gbps FC and FICON host adapters, 8 Gbps device adapters, and 6 Gbps SAS connectivity to smaller form factor (SFF) 2.5-inch SAS drives. IBM Easy Tier will provide sub-LUN automated tiering between Solid-State Drives and spinning disk. The denser packaging with SFF drives means that we can pack over 1000 drives in only three frames, compared to five frames required for the DS8700.
The [IBM System Storage SAN Volume Controller] software release v6.1 brings Easy Tier sub-LUN automated tiering to the rest of the world. IBM Easy Tier moves the hottest, most active extents up to Solid-State Drives (SSD) and moves the coldest, least active down to spinning disk. This works whether the SSD is inside the SVC 2145-CF8 nodes, or in the managed disk pool.
Tired of waiting for EMC to finally deliver FAST v2 for your VMAX? It has been 18 months since they first announced that someday they would have sub-LUN automatic tiering. What is taking them so long? Why not virtualize your VMAX with SVC, and you can have it sooner!
SVC 6.1 also upgrades to a sexy new web-based GUI, which like the one for the IBM Storwize V7000, is based on the latest HTML5 and dojo widget standards. Inspired by the popular GUI from the IBM XIV Storage System, this GUI has greatly improved ease-of-use.
A client asked me to explain "Nearline storage" to them. This was easy, I thought, as I started my IBM career on DFHSM, now known as DFSMShsm for z/OS, which was created in 1977 to support the IBM 3850 Mass Storage System (MSS), a virtual storage system that blended disk drives and tape cartridges with robotic automation. Here is a quick recap:
Online storage is immediately available for I/O. This includes DRAM memory, solid-state drives (SSD), and always-on spinning disk, regardless of rotational speed.
Nearline storage is not immediately available, but can be made online quickly without human intervention. This includes optical jukeboxes, automated tape libraries, as well as spin-down massive array of idle disk (MAID) technologies.
Offline storage is not immediately available, and requires some human intervention to bring online. This can include USB memory sticks, CD/DVD optical media, shelf-resident tape cartridges, or other removable media.
Sadly, it appears a few storage manufacturers and vendors have been misusing the term "Nearline" to refer to "slower online" spinning disk drives. I find this [June 2005 technology paper from Seagate], and this [2002 NetApp Press Release], the latter of which included this contradiction for their "NearStore" disk array. Here is the excerpt:
"Providing online access to reference information—NetApp nearline storage solutions quickly retrieve and replicate reference and archive information maintained on cost-effective storage—medical images, financial models, energy exploration charts and graphs, and other data-intensive records can be stored economically and accessed in multiple locations more quickly than ever"
Which is it, "online access" or "nearline storage"?
If a client asked why slower drives consume less energy or generate less heat, I could explain that, but if they ask why slower drives must have SATA connections, that is a different discussion. The speed of a drive and its connection technology are for the most part independent. A 10K RPM drive can be made with FC, SAS or SATA connection.
I am opposed to using "Nearlne" just to distinguish between four-digit speeds (such as 5400 or 7200 RPM) versus "online" for five-digit speeds (10,000 and 15,000 RPM). The difference in performance between 10K RPM and 7200 RPM spinning disks is miniscule compared to the differences between solid-state drives and any spinning disk, or the difference between spinning disk and tape.
I am also opposed to using the term "Nearline" for online storage systems just because they are targeted for the typical use cases like backup, archive or other reference information that were previously directed to nearline devices like automated tape libraries.
Can we all just agree to refer to drives as "fast" or "slow", or give them RPM rotational speed designations, rather than try to incorrectly imply that FC and SAS drives are always fast, and SATA drives are always slow? Certainly we don't need new terms like "NL-SAS" just to represent a slower SAS connected drive.
Well, it feels like Tuesday and you know what that means... "IBM Announcement Day!" Actually, today is Wednesday, but since Monday was Memorial Day holiday here in the USA, my week is day-shifted. Yesterday, IBM announced its latest IBM FlashCopy Manager v2.2 release. Fellow blogger, Del Hoobler (IBM) has also posted something on this out atthe [Tivoli Storage Blog].
IBM FlashCopy Manager replaces two previous products. One was called Tivoli Storage Manager for Copy Services, the other was called Tivoli Storage Manager for Advanced Copy Services. To say people were confused between these two was an understatement, the first was for Windows, and the second was for UNIX and Linux operating systems. The solution? A new product that replaces both of these former products to support Windows, UNIX and Linux! Thus, IBM FlashCopy Manager was born. I introduced this product back in 2009 in my post [New DS8700 and other announcements].
IBM Tivoli Storage FlashCopy Manager provides what most people with "N series SnapManager envy" are looking for: application-aware point-in-time copies. This product takes advantage of the underlying point-in-time interfaces available on various disk storage systems:
FlashCopy on the DS8000 and SAN Volume Controller (SVC)
Snapshot on the XIV storage system
Volume Shadow Copy Services (VSS) interface on the DS3000, DS4000, DS5000 and non-IBM gear that supports this Microsoft Windows protocol
For Windows, IBM FlashCopy Manager can coordinate the backup of Microsoft Exchange and SQL Server. The new version 2.2 adds support for Exchange 2010 and SQL Server 2008 R2. This includes the ability to recover an individual mailbox or mail item from an Exchange backup. The data can be recovered directly to an Exchange server, or to a PST file.
For UNIX and Linux, IBM FlashCopy Manager can coordinate the backup of DB2, SAP and Oracle databases. Version 2.2 adds support specific Linux and Solaris operating systems, and provides a new capability for database cloning. Basically, database cloning restores a database under a new name with all the appropriate changes to allow its use for other purposes, like development, test or education training. A new "fcmcli" command line interface allows IBM FlashCopy Manager to be used for custom applications or file systems.
A common misperception is that IBM FlashCopy Manager requires IBM Tivoli Storage Manager backup software to function. That is not true. You have two options:
In Stand-alone mode, it's just you, the application, IBM FlashCopy Manager and your disk system. IBM FlashCopy Manager coordinates the point-in-time copies, maintains the correct number of versions, and allows you to backup and restore directly disk-to-disk.
Unified Recovery Management with Tivoli Storage Manager
Of course, the risk with relying only on point-in-time copies is that in most cases, they are on the same disk system as the original data. The exception being virtual disks from the SAN Volume Controller. IBM FlashCopy Manager can be combined with IBM Tivoli Storage Manager so that the point-in-time copies can be copied off to a local or remote TSM server, so that if the disk system that contains both the source and the point-in-time copies fails, you have a backup copy from TSM. In this approach, you can still restore from the point-in-time copies, but you can also restore from the TSM backups as well.
IBM FlashCopy Manager is an excellent platform to connect application-aware fucntionality with hardware-based copy services.
Well, I'm back safely from my tour of Asia. I am glad to report that Tokyo, Beijing and Kuala Lumpur are pretty much how I remember them from the last time I was there in each city. I have since been fighting jet lag by watching the last thirteen episodes of LOST season 6 and the series finale.
Recently, I have started seeing a lot of buzz on the term "Storage Federation". The concept is not new, but rather based on the work in database federation, first introduced in 1985 by [A federated architecture for information management] by Heimbigner and McLeod. For those not familiar with database federation, you can take several independent autonomous databases, and treat them as one big federated system. For example, this would allow you to issue a single query and get results across all the databases in the federated system. The advantage is that it is often easier to federate several disparate heterogeneous databases than to merge them into a single database. [IBM Infosphere Federation Server] is a market leader in this space, with the capability to federate DB2, Oracle and SQL Server databases.
Storage expansion: You want to increase the storage capacity of an existing storage system that cannot accommodate the total amount of capacity desired. Storage Federation allows you to add additional storage capacity by adding a whole new system.
Storage migration: You want to migrate from an aging storage system to a new one. Storage Federation allows the joining of the two systems and the evacuation from storage resources on the first onto the second and then the first system is removed.
Safe system upgrades: System upgrades can be problematic for a number of reasons. Storage Federation allows a system to be removed from the federation and be re-inserted again after the successful completion of the upgrade.
Load balancing: Similar to storage expansion, but on the performance axis, you might want to add additional storage systems to a Storage Federation in order to spread the workload across multiple systems.
Storage tiering: In a similar light, storage systems in a Storage Federation could have different capacity/performance ratios that you could use for tiering data. This is similar to the idea of dynamically re-striping data across the disk drives within a single storage system, such as with 3PAR's Dynamic Optimization software, but extends the concept to cross storage system boundaries.
To some extent, IBM SAN Volume Controller (SVC), XIV, Scale-Out NAS (SONAS), and Information Archive (IA) offer most, if not all, of these capabilities. EMC claims its VPLEX will be able to offer storage federation, but only with other VPLEX clusters, which brings up a good question. What about heterogenous storage federation? Before anyone accuses me of throwing stones at glass houses, let's take a look at each IBM solution:
IBM SAN Volume Controller
The IBM SAN Volume Controller has been doing storage federation since 2003. Not only can IBM SAN Volume Controller bring together storage from a variety of heterogenous storage, the SVC cluster itself can be a mix of different hardware models. You can have a 2145-8A4 node pair, 2145-8G4 node pair, and the new 2145-CF8 node pair, all combined together into a single SVC cluster. Upgrading SVC hardware nodes in an SVC cluster is always non-disruptive.
IBM XIV storage system
The IBM XIV has two kinds of independent modules. Data modules have processor, cache and 12 disks. Interface modules are data modules with additional processor, FC and Ethernet (iSCSI) adapters. Because these two modules play different roles in an XIV "colony", that number of each type is predetermined. Entry-level six-module systems have 2 interface and 4 data modules. Full 15-module systems have 6 interface and 9 data modules. Individual modules can be added or removed non-disruptively in an XIV.
IBM Scale-Out NAS
The SONAS is comprised of three kinds of nodes that work together in concert. A management node, one or more interface nodes, and two or more storage nodes. The storage nodes are paired to manage up to 240 nodes in a storage pod. Individual interface or data nodes can be added or removed non-disruptively in the SONAS. The underlying technology, the General Parallel File System, has been doing storage federation since 1996 for some of the largest top 500 supercomputers in the world.
IBM Information Archive (IA)
For the IA, there are 1, 2 or 3 nodes, which manages a set of collections. A collection can either be file-based using industry-standard NAS protocols, or object-based using the popular System Storage™ Archive Manager (SSAM) interface. Normally, you have as many collections as you have nodes, but nodes are powerful enough to manage two collections to provide N-1 availability. This allows a node to be removed, and a new node added into the IA "colony", in a non-disruptive manner.
Even in an ant colony, there are only a few types of ants, with typically one queen, several males, and lots of workers. But all the ants are red. You don't see colonies that mix between different species of ants. For databases, federation was a way to avoid the much harder task of merging databases from different platforms. For storage, I am surprised people have latched on to the term "federation", given our mixed results in the other "federations" we have formed, which I have conveniently (IMHO) ranked from least effective to most effective:
The Union of Soviet Socialist Republics (USSR)
My father used to say, "If the Soviet Union were in charge of the Sahara desert, they would run out of sand in 50 years." The [Soviet Union] actually lasted 68 years, from 1922 to 1991.
The United Nations (UN)
After the previous League of Nations failed, the UN was formed in 1945 to facilitate cooperation in international law, international security, economic development, social progress, human rights, and the achieving of world peace by stopping wars between countries, and to provide a platform for dialogue.
The European Union (EU)
With the collapse of the Greek economy, and the [rapid growth of debt] in the UK, Spain and France, there are concerns that the EU might not last past 2020.
The United States of America (USA)
My own country is a federation of states, each with its own government. California's financial crisis was compared to the one in Greece. My own state of Arizona is under boycott from other states because of its recent [immigration law]. However, I think the US has managed better than the EU because it has evolved over the past 200 years.
The Organization of the Petroleum Exporting Countries [OPEC]
Technically, OPEC is not a federation of cooperating countries, but rather a cartel of competing countries that have agreed on total industry output of oil to increase individual members' profits. Note that it was a non-OPEC company, BP, that could not "control their output" in what has now become the worst oil spill in US history. OPEC was formed in 1960, and is expected to collapse sometime around 2030 when the world's oil reserves run out. Matt Savinar has a nice article on [Life After the Oil Crash].
United Federation of Planets
The [Federation] fictitiously described in the Star Trek series appears to work well, an optimistic view of what federations could become if you let them evolve long enough.
Given the mixed results with "federation", I think I will avoid using the term for storage, and stick to the original term "scale-out architecture".
Here I am, day 11 of a 17-day business trip, on my last leg of the trip this week, in Kuala Lumpur in Malaysia. I have been flooded with requests to give my take on EMC's latest re-interpretation of storage virtualization, VPLEX.
I'll leave it to my fellow IBM master inventor Barry Whyte to cover the detailed technical side-by-side comparison. Instead, I will focus on the business side of things, using Simon Sinek's Why-How-What sequence. Here is a [TED video] from Garr Reynold's post
[The importance of starting from Why].
Let's start with the problem we are trying to solve.
Problem: migration from old gear to new gear, old technology to new technology, from one vendor to another vendor, is disruptive, time-consuming and painful.
Given that IT storage is typically replaced every 3-5 years, then pretty much every company with an internal IT department has this problem, the exception being those companies that don't last that long, and those that use public cloud solutions. IT storage can be expensive, so companies would like their new purchases to be fully utilized on day 1, and be completely empty on day 1500 when the lease expires. I have spoken to clients who have spent 6-9 months planning for the replacement or removal of a storage array.
A solution to make the data migration non-disruptive would benefit the clients (make it easier for their IT staff to keep their data center modern and current) as well as the vendors (reduce the obstacle of selling and deploying new features and functions). Storage virtualization can be employed to help solve this problem. I define virtualization as "technology that makes one set of resources look and feel like a different set of resources, preferably with more desirable characteristics.". By making different storage resources, old and new, look and feel like a single type of resource, migration can be performed without disrupting applications.
Before VPLEX, here is a breakdown of each solution:
Non-disruptive tech refresh, and a unified platform to provide management and functionality across heterogeneous storage.
Non-disruptive tech refresh, and a unified platform to provide management and functionality between internal tier-1 HDS storage, and external tier-2 heterogeneous storage.
Non-disruptive tech refresh, with unified multi-pathing driver that allows host attachment of heterogeneous storage.
New in-band storage virtualization device
Add in-band storage virtualization to existing storage array
New out-of-band storage virtualization device with new "smart" SAN switches
SAN Volume Controller
HDS USP-V and USP-VM
For IBM, the motivation was clear: Protect customers existing investment in older storage arrays and introduce new IBM storage with a solution that allows both to be managed with a single set of interfaces and provide a common set of functionality, improving capacity utilization and availability. IBM SAN Volume Controller eliminated vendor lock-in, providing clients choice in multi-pathing driver, and allowing any-to-any migration and copy services. For example, IBM SVC can be used to help migrate data from an old HDS USP-V to a new HDS USP-V.
With EMC, however, the motivation appeared to protect software revenues from their PowerPath multi-pathing driver, TimeFinder and SRDF copy services. Back in 2005, when EMC Invista was first announced, these three software represented 60 percent of EMC's bottom-line profit. (Ok, I made that last part up, but you get my point! EMC charges a lot for these.)
Back in 2006, fellow blogger Chuck Hollis (EMC) suggested that SVC was just a [bump in the wire] which could not possibly improve performance of existing disk arrays. IBM showed clients that putting cache(SVC) in front of other cache(back end devices) does indeed improve performance, in the same way that multi-core processors successfully use L1/L2/L3 cache. Now, EMC is claiming their cache-based VPLEX improves performance of back-end disk. My how EMC's story has changed!
So now, EMC announces VPLEX, which sports a blend of SVC-like and Invista-like characteristics. Based on blogs, tweets and publicly available materials I found on EMC's website, I have been able to determine the following comparison table. (Of course, VPLEX is not yet generally available, so what is eventually delivered may differ.)
Scalable, 1 to 4 node-pairs
One size fits all, single pair of CPCs
SVC-like, 1 to 4 director-pairs
Works with any SAN switches or directors
Required special "smart" switches (vendor lock-in)
SVC-like, works with any SAN switches or directors

SVC-like, Read and write-through cache, offering the ability to improve performance.
Space-Efficient Point-in-Time copies
SVC FlashCopy supports up to 256 space-efficient targets, copies of copies, read-only or writeable, and incremental persistent pairs.
Like Invista, No
Remote distance mirror
Choice of SVC Metro Mirror (synchronous up to 300km) and Global Mirror (asynchronous), or use the functionality of the back-end storage arrays
No native support, use functionality of back-end storage arrays, or purchase separate product called EMC RecoverPoint to cover this lack of functionality
Limited synchronous remote-distance mirror within VPLEX (up to 100km only), no native asynchronous support, use functionality of back-end storage arrays
Provides thin provisioning to devices that don't offer this natively
Like Invista, No
SVC Split-Cluster allows concurrent read/write access of data to be accessed from hosts at two different locations several miles apart
I don't think so
PLEX-Metro, similar in concept but implemented differently
Non-disruptive tech refresh
Can upgrade or replace storage arrays, SAN switches, and even the SVC nodes software AND hardware themselves, non-disruptively
Tech refresh for storage arrays, but not for Invista CPCs
Tech refresh of back end devices, and upgrade of VPLEX software, non-disruptively. Not clear if VPLEX engines themselves can be upgraded non-disruptively like the SVC.
Heterogeneous Storage Support
Broad support of over 140 different storage models from all major vendors, including all CLARiiON, Symmetrix and VMAX from EMC, and storage from many smaller startups you may not have heard of
Invista-like. VPLEX claims to support a variety of arrays from a variety of vendors, but as far as I can find, only DS8000 supported from the list of IBM devices. Fellow blogger Barry Burke (EMC) suggests [putting SVC between VPLEX and third party storage devices] to get the heterogeneous coverage most companies demand.
Back-end storage requirement
Must define quorum disks on any IBM or non-IBM back end storage array. SVC can run entirely on non-IBM storage arrays
HP SVSP-like, requires at least one EMC storage array to hold metadata
SVC 2145-CF8 model supports up to four solid-state drives (SSD) per node that can treated as managed disk to store end-user data
Invista-like. VPLEX has an internal 30GB SSD, but this is used only for operating system and logs, not for end-user data.
In-band virtualization solutions from IBM and HDS dominate the market. Being able to migrate data from old devices to new ones non-disruptively turned out to be only the [tip of the iceberg] of benefits from storage virtualization. In today's highly virtualized server environment, being able to non-disruptively migrate data comes in handy all the time. SVC is one of the best storage solutions for VMware, Hyper-V, XEN and PowerVM environments. EMC watched and learned in the shadows, taking notes of what people like about the SVC, and decided to follow IBM's time-tested leadership to provide a similar offering.
EMC re-invented the wheel, and it is round. On a scale from Invista (zero) to SVC (ten), I give EMC's new VPLEX a six.
Last week, I presented "An Introduction to Cloud Computing" for two hours to the local Institute of Management Accountants [IMA] for their Continuing Professional Education [CPE]. Since I present IBM's leadership in Cloud Storage offerings, I have had to become an expert in Cloud Computing overall. The audience was a mix of bookkeepers, accountants, auditors, comptrollers, CPAs, and accounting teachers.
Here is a sample of the questions I took during and after my presentation:
If I need to shut down host machine, I lose all my virtual machines as well?
No, it is possible to seemlessly move virtual machines from one host to another. If you need to shut down a host machine, move all the VMs to other hosts, then you can shut down the empty host without impacting business.
Does the SaaS provider have to build their own app, can they not buy an app and then rent it out?
Yes, but they won't have competitive differentiation, and the software development they buy from will want a big cut of the action. SaaS developers that build their own applications can keep more of the profits for themselves.
How do backups work in cloud computing? Do I have to contact someone at the cloud computing company to find the backup tape?
Large datacenters often keep the most recent backups on disk, and older versions on tape in automated tape libraries that can fetch your backup in less than 2 minutes. Because of this, there is no need to talk to anyone, you can schedule or invoke your own backups, and often perform the recovery yourself using self-service tools.
Last month, my sister tried to rent a car during the week the Tucson Gem Show, but they were out of cars she wanted to drive. Could this happen with Cloud Computing?
Not likely. With rental cars, the cars have to be physically in Tucson to rent them. Rental companies could have brought cars down from Phoenix to satisfy demand. With Cloud Computing, it is all accessible over the global network, you are not limited to the cloud providers nearest you.
Is there a reason why Amazon Web Services (AWS) charges more for a Windows image than a Linux image?
Yes, Amazon and Microsoft have a patent cross-licensing agreement where Amazon pays Microsoft for the priveledge of offering Windows-based images on their EC2 cloud infrastructure. It just makes business sense to pass those costs onto the consumer. Linux is a free open source operating system, and is often the better choice.
So if we rent a machine from Amazon, they send it to my accounting office? What exactly am I getting for 12 cents per hour?
No. The computer remains in their datacenter. You get a virtual machine that runs 1.2Ghz Intel processor, with 1700MB of RAM, and 160GB of hard disk space, with Windows operating system running on it, comparable to a machine you can get at the local BestBuy, but instead of it running in the next room, it is running in a datacenter somewhere else in the United States with electricity and air conditioning.
You access it remotely from your desktop or laptop PC.
Why would I ever rent more than one computer?
It depends on your workload. For example, Derek Gottfrid at the New York Times needed to convert 11 million articles from TIFF format to PDF format so that he could put them up on the web. This would have taken him months using a single computer, so he rented 100 computers and got the entire stack converted in 24 hours, for a cost of about $240. See the articles [Self-Service, Prorated, Super Computing] and [TimesMachine] for details.
What about throughput? Won't I need to run cables from my accounting office to this cloud computing data center?
You will need connectivity, most likely from connections provided by your local telephone or cable company, or through the Internet. Certainly, there can be cases where direct privately-owned fiber optic cables, known as "dark fiber", can directly connect consumers to local Cloud service providers, for added security.
What about medical records? Will Cloud Computing help the Healthcare industry?
Yes, hospitals are finding that digitizing their records greatly reduces costs. IBM offers the Grid Medical Archive Solution [GMAS] as a private cloud storage solution to store X-ray images and other electronic medical records on disk and tape, and these records can be accessed from multiple hospitals and clinics, wherever the doctor or patient happens to be.
The advantage of personal computers was individualization, I could put on my own choices of software, and customize my own settings, won't we lose this with Cloud Computing?
Yes, customized software and settings cost companies millions of dollars with help desk calls. Cloud Computing attempts to provide some standardization, reducing the amount of effort to support IT operations.
Won't putting all the computers into a big datacenter make them more vulnerable to hackers?
Security is a well-known concern, but this is being addressed with encryption, access control lists, multi-tenancy isolation, and VPN connections.
My daughter has a BlackBerry or iPod or something, and when we mentioned that someone in Phoenix wore a monkey suit to avoid photo-radar speed cameras, she was able to pull up a picture on her little hand-held thing, is this the future?
Yes, mobile phones and other hand-held devices now have internet access to take advantage of Cloud Computing services. People will be able to access the information they need from wherever they happen to be. (You can see the picture here: [Man Dons Mask for Speed-Camera Photos])
IBM offers a variety of Cloud Computing services, as well as customized solutions and integrated systems that can be deployed on-premises behind your corporate firewall. To learn more, go to [ibm.com/cloud].
The second speaker was local celebrity Dan Ryan presenting the financials for the upcoming [Rosemont Copper] mining operations. Copper is needed for emerging markets, such as hybrid vehicles and wind turbines. Copper is a major industry in Arizona.
This week I got a comment on my blog post [IBM Announces another SSD Disk offering!]. The exchange involved Solid State Disk storage inside the BladeCenter and System x server line. Sandeep offered his amazing performance results, but we have no way to get in contact with him. So, for those interested, I have posted on SlideShare.net a quick five-chart presentation on recent tests with various SSD offerings on the eX5 product line here:
Continuing my drawn out coverage of IBM's big storage launch of February 9, today I'll cover the IBM System Storage TS7680 ProtecTIER data deduplication gateway for System z.
On the host side, TS7680 connects to mainframe systems running z/OS or z/VM over FICON attachment, emulating an automated tape library with 3592-J1A devices. The TS7680 includes two controllers that emulate the 3592 C06 model, with 4 FICON ports each. Each controller emulates up to 128 virtual 3592 tape drives, for a total of 256 virtual drives per TS7680 system. The mainframe sees up to 1 million virtual tape cartridges, up to 100GB raw capacity each, before compression. For z/OS, the automated library has full SMS Tape and Integrated Library Management capability that you would expect.
Inside, the two control units are both connected to a redundant pair cluster of ProtecTIER engines running the HyperFactor deduplication algorithm that is able to process the deduplication inline, as data is ingested, rather than post-process that other deduplication solutions use. These engines are similar to the TS7650 gateway machines for distributed systems.
On the back end, these ProtecTIER deduplication engines are then connected to external disk, up to 1PB. If you get 25x data deduplication ratio on your data, that would be 25PB of mainframe data stored on only 1PB of physical disk. The disk can be any disk supported by ProtecTIER over FCP protocol, not just the IBM System Storage DS8000, but also the IBM DS4000, DS5000 or IBM XIV storage system, various models of EMC and HDS, and of course the IBM SAN Volume Controller (SVC) with all of its supported disk systems.
It's Tuesday, and that means more IBM announcements!
I haven't even finished blogging about all the other stuff that got announced last week, and here we are with more announcements. Since IBM's big [Pulse 2010 Conference] is next week, I thought I would cover this week's announcement on Tivoli Storage Manager (TSM) v6.2 release. Here are the highlights:
Client-Side Data Deduplication
This is sometimes referred to as "source-side" deduplication, as storage admins can get confused on which servers are clients in a TSM client-server deployment. The idea is to identify duplicates at the TSM client node, before sending to the TSM server. This is done at the block level, so even files that are similar but not identical, such as slight variations from a master copy, can benefit. The dedupe process is based on a shared index across all clients, and the TSM server, so if you have a file that is similar to a file on a different node, the duplicate blocks that are identical in both would be deduplicated.
This feature is available for both backup and archive data, and can also be useful for archives using the IBM System Storage Archive Manager (SSAM) v6.2 interface.
Simplified management of Server virtualization
TSM 6.2 improves its support of VMware guests by adding auto-discovery. Now, when you spontaneously create a new virtual machine OS guest image, you won't have to tell TSM, it will discover this automatically! TSM's legendary support of VMware Consolidated Backup (VCB) now eliminates the manual process of keeping track of guest images. TSM also added support of the Vstorage API for file level backup and recovery.
While IBM is the #1 reseller of VMware, we also support other forms of server virtualization. In this release, IBM adds support for Microsoft Hyper-V, including support using Microsoft's Volume Shadow Copy Services (VSS).
Automated Client Deployment
Do you have clients at all different levels of TSM backup-archive client code deployed all over the place? TSM v6.2 can upgrade these clients up to the latest client level automatically, using push technology, from any client running v5.4 and above. This can be scheduled so that only certain clients are upgraded at a time.
Simultaneous Background Tasks
The TSM server has many background administrative tasks:
Migration of data from one storage pool to another, based on policies, such as moving backups and archives on a disk pool over to a tape pools to make room for new incoming data.
Storage pool backup, typically data on a disk pool is copied to a tape pool to be kept off-site.
Copy active data. In TSM terminology, if you have multiple backup versions, the most recent version is called the active version, and the older versions are called inactive. TSM can copy just the active versions to a separate, smaller disk pool.
In previous releases, these were done one at a time, so it could make for a long service window. With TSM v6.2, these three tasks are now run simultaneously, in parallel, so that they all get done in less time, greatly reducing the server maintenance window, and freeing up tape drives for incoming backup and archive data. Often, the same file on a disk pool is going to be processed by two or more of these scheduled tasks, so it makes sense to read it once and do all the copies and migrations at one time while the data is in buffer memory.
Enhanced Security during Data Transmission
Previous releases of TSM offered secure in-flight transmission of data for Windows and AIX clients. This security uses Secure Socket Layer (SSL) with 256-bit AES encryption. With TSM v6.2, this feature is expanded to support Linux, HP-UX and Solaris.
Improved support for Enterprise Resource Planning (ERP) applications
I remember back when we used to call these TDPs (Tivoli Data Protectors). TSM for ERP allows backup of ERP applications, seemlessly integrating with database-specific tools like IBM DB2, Oracle RMAN, and SAP BR*Tools. This allows one-to-many and many-to-one configurations between SAP servers and TSM servers. In other words, you can have one SAP server backup to several TSM servers, or several SAP servers backup to a single TSM server. This is done by splitting up data bases into "sub-database objects", and then process each object separately. This can be extremely helpful if you have databases over 1TB in size. In the event that backing up an object fails and has to be re-started, it does not impact the backup of the other objects.
Continuing on the [IBM Storage Launch of February 9], John Sing has offered to write the following guest post about the [announcement] of IBM Scale Out Network Attached Storage [IBM SONAS]. John and I have known each other for a while, traveled the world to work with clients and speak at conferences. He is an Executive IT Consultant on the SONAS team.
Guest Post written by John Sing, IBM San Jose, California
What is IBM SONAS? It’s many things, so let’s start with this list:
It’s IBM’s delivery of a productized, pre-packaged Scale Out NAS global virtual file server, delivered in a easy-to-use appliance
IBM’s solution for large enterprise file-based storage requirements, where massive scale in capacity and extreme performance is required, especially for today’s modern analytics-based Competitive Advantage IT applications
Scales to many petabytes of usable storage and billions of files in a single global namespace
Provides integrated central management, central deployment of petabyte levels of storage
Modular commercial-off-the-shelf [COTS] building blocks. I/O, storage, network capacity scale independently of each other. Up to 30 interface nodes and 60 storage nodes, in an IBM General Parallel File System [GPFS]-based cluster. Each 10Gb CEE interface node port is capable of streaming at 900 MB/sec
Files are written in block-sized chunks, striped over as many multiple disk drives in parallel – aggregating throughput on a massive scale (both read and write), as well as providing auto-tuning, auto-balancing
Functionality delivered via one program product, IBM SONAS Software, which provides all of above functions, along with clustered CIFS, NFS v2/v3 with session auto-failover, FTP, high availability, and more
IBM SONAS makes automated tiered storage achievable and realistic at petabyte levels:
Integrated high performance parallel scan engine capable of identifying files at over 10 million files per minute per node
Integrated parallel data movement engine to physically relocate the data within tiered storage
And we’re just scratching the surface. IBM has plans to deploy additional protocols, storage hardware options, and software features.
However, the real question of interest should be, “who really needs that much storage capacity and throughput horsepower?”
The answer may surprise you. IMHO, the answer is: almost any modern enterprise that intends to stay competitive. Hmmm…… Consider this: the reason that IT exists today is no longer to simply save cost (that may have been true 10 years ago). Everyone is reducing cost… but how much competitive advantage is purchased through “let’s cut our IT budget by 10% this year”?
Notice that in today’s world, there are (many) bright people out there, changing our world every day through New Intelligence Competitive Advantage analytics-based IT applications such as real time GPS traffic data, real time energy monitoring and redirection, real time video feed with analytics, text analytics, entity analytics, real time stream computing, image recognition applications, HDTV video on demand, etc. Think of how GPS industry, cell phone / Twitter / Facebook, iPhone and iPad applications, as examples, are creating whole new industries and markets almost overnight.
Then start asking yourself, “What's behind these Competitive Advantage IT applications – as they are the ones that are driving all my storage growth? Why do they need so much storage? What do those applications mean for my storage requirements?”
To be “real-time”, long-held IT paradigms are being broken every day. Things like “data proximity”: we can no longer can extract terabytes of data from production databases and load them to a data warehouse – where’s the “real-time” in that? Instead, today’s modern analytics-based applications demand:
Multiple processes and servers (sometimes numbering in the 100s) simultaneously ….
Running against hundreds of terabytes of data of live production data, streaming in from expanding number of smarter sensors, input devices, users
Producing digital image-intensive results that must be programatically sent to an ever increasing number of mobile devices in geographically dispersed storage
Requiring parallel performance levels, that used to be the domain only of High Performance Computing (HPC)
This is a major paradigm shift in storage – and that is the solution and storage capabilities that IBM SONAS is designed to address. And of course, you should be able to save significant cost through the SONAS global virtual file server consolidation and virtualization as well.
Certainly, this topic warrants more discussion. If you found it interesting, contact me, your local IBM Business Partner or IBM Storage rep to discuss Competitive Advantage IT applications and SONAS further.
Wrapping up my coverage of the Data Center Conference 2009, the week ends with a celebration. This year we had six "Hospitality Suites" sponsored by various different vendors. Each suite has its own theme, decorations and entertainment. The first suite was VMware's "Cloud 9 Ultra Lounge" which offered blue cotton candy martinis. IBM is the leading reseller of VMware.
When the red martini liquid was poured on top of the blue cotton candy, the result was a nasty muddish brown grey color. The guy on the left chose to get the martini without the blue cotton candy. We joked that this is perhaps a good metaphor for cloud computing in general. It looks good on paper, until you actually put it all together and realize it does not look as blue and puffy as you were expecting. However, it tasted good!
Next suite was sponsored by Cisco, one of IBM's storage networking partners. Cisco also decorated in blue, as the guy Jake in the middle demonstrates.
Next suite was sponsored by Brocade, our supplier for IBM-branded networking gear. They went with a red-and-black color scheme. Sadly, many of my pictures inside involved straight jackets and unicycles, so not appropriate for this blog. However, it was easy to remember that they were talking about their "extraordinary networks". Makes you want to help out Brocade by contacting your nearest IBM storage sales rep and buy yourself a SAN768B or two.
Somewhere along the way, we picked up Hawaiian leis at the "Margaritaville" Hospitality Suite, compliments of sponsor APC by Schneider Electric. We had the best "Filet Mignon" appetizers at "Club Dedupe" by our competitor DataDomain, and some fun with my friends over at Computer Associates' "Top Gun" suite. Pictured at right are Paula Koziol with Christian Barrera from Argentina. A good time was had by all.
Well, it's Tuesday again, but this time, today we had our third big storage launch of 2009! A lot got announced today as part of IBM's big "Dynamic Infrastructure" marketing campaign. I will just focus on the
disk-related announcements today:
IBM System Storage DS8700
IBM adds a new model to its DS8000 series with the
[IBM System Storage DS8700]. Earlier this month, fellow blogger and arch-nemesis Barry Burke from EMC posted [R.I.P DS8300] on this mistaken assumption that the new DS8700 meant that DS8300 was going away, or that anyone who bought a DS8300 recently would be out of luck. Obviously, I could not respond until today's announcement, as the last thing I want to do is lose my job disclosing confidential information. BarryB is wrong on both counts:
IBM will continue to sell the DS8100 and DS8300, in addition to the new DS8700.
Clients can upgrade their existing DS8100 or DS8300 systems to DS8700.
BarryB's latest post [What's In a Name - DS8700] is fair game, given all the fun and ridicule everyone had at his expense over EMC's "V-Max" name.
So the DS8700 is new hardware with only 4 percent new software. On the hardware side, it uses faster POWER6 processors instead of POWER5+, has faster PCI-e buses instead of the RIO-G loops, and faster four-port device adapters (DAs) for added bandwidth between cache and drives. The DS8700 can be ordered as a single-frame dual 2-way that supports up to 128 drives and 128GB of cache, or as a dual 4-way, consisting of one primary frame, and up to four expansion frames, with up to 384GB of cache and 1024 drives.
Not mentioned explicitly in the announcements were the things the DS8700 does not support:
ESCON attachment - Now that FICON is well-established for the mainframe market, there is no need to support the slower, bulkier ESCON options. This greatly reduced testing effort. The 2-way DS8700 can support up to 16 four-port FICON/FCP host adapters, and the 4-way can support up to 32 host adapters, for a maximum of 128 ports. The FICON/FCP host adapter ports can auto-negotiate between 4Gbps, 2Gbps and 1Gbps as needed.
LPAR mode - When IBM and HDS introduced LPAR mode back in 2004, it sounded like a great idea the engineers came up with. Most other major vendors followed our lead to offer similar "partitioning". However, it turned out to be what we call in the storage biz a "selling apple" not a "buying apple". In other words, something the salesman can offer as a differentiating feature, but that few clients actually use. It turned out that supporting both LPAR and non-LPAR modes merely doubled the testing effort, so IBM got rid of it for the DS8700.
Update: I have been reminded that both IBM and HDS delivered LPAR mode within a month of each other back in 2004, so it was wrong for me to imply that HDS followed IBM's lead when obviously development happened in both companies for the most part concurrently prior to that. EMC was late to the "partition" party, but who's keeping track?
Initial performance tests show up to 50 percent improvement for random workloads, and up to 150 percent improvement for sequential workloads, and up to 60 percent improvement in background data movement for FlashCopy functions. The results varied slightly between Fixed Block (FB) LUNs and Count-Key-Data (CKD) volumes, and I hope to see some SPC-1 and SPC-2 benchmark numbers published soon.
The DS8700 is compatible for Metro Mirror, Global Mirror, and Metro/Global Mirror with the rest of the DS8000 series, as well as the ESS model 750, ESS model 800 and DS6000 series.
New 600GB FC and FDE drives
IBM now offers [600GB drives] for the DS4700 and DS5020 disk systems, as well as the EXP520 and EXP810 expansion drawers. In each case, we are able to pack up to 16 drives into a 3U enclosure.
Personally, I think the DS5020 should have been given a DS4xxx designation, as it resembles the DS4700
more than the other models of the DS5000 series. Back in 2006-2007, I was the marketing strategist for IBM System Storage product line, and part of my job involved all of the meetings to name or rename products. Mostly I gave reasons why products should NOT be renamed, and why it was important to name the products correctly at the beginning.
IBM System Storage SAN Volume Controller hardware and software
Fellow IBM master inventory Barry Whyte has been covering the latest on the [SVC 2145-CF8 hardware]. IBM put out a press release last week on this, and today is the formal announcement with prices and details. Barry's latest post
[SVC CF8 hardware and SSD in depth] covers just part of the entire
The other part of the announcement was the [SVC 5.1 software] which can be loaded
on earlier SVC models 8F2, 8F4, and 8G4 to gain better performance and functionality.
To avoid confusion on what is hardware machine type/model (2145-CF8 or 2145-8A4) and what is software program (5639-VC5 or 5639-VW2), IBM has introduced two new [Solution Offering Identifiers]:
5465-028 Standard SAN Volume Controller
5465-029 Entry Edition SAN Volume Controller
The latter is designed for smaller deployments, supports only a single SVC node-pair managing up to
150 disk drives, available in Raven Black or Flamingo Pink.
EXN3000 and EXP5060 Expansion Drawers
IBM offers the [EXN3000 for the IBM N series]. These expansion drawers can pack 24 drives in a 4U enclosure. The drives can either be all-SAS, or all-SATA, supporting 300GB, 450GB, 500GB and 1TB size capacity drives.
The [EXP5060 for the IBM DS5000 series] is a high-density expansion drawer that can pack up to 60 drives into a 4U enclosure. A DS5100 or DS5300
can handle up to eight of these expansion drawers, for a total of 480 drives.
Pre-installed with Tivoli Storage Productivity Center Basic Edition. Basic Edition can be upgraded with license keys to support Data, Disk and Standard Edition to extend support and functionality to report and manage XIV, N series, and non-IBM disk systems.
Pre-installed with Tivoli Key Lifecycle Manager (TKLM). This can be used to manage the Full Disk Encryption (FDE) encryption-capable disk drives in the DS8000 and DS5000, as well as LTO and TS1100 series tape drives.
IBM Tivoli Storage FlashCopy Manager v2.1
The [IBM Tivoli Storage FlashCopy Manager V2.1] replaces two products in one. IBM used
to offer IBM Tivoli Storage Manager for Copy Services (TSM for CS) that protected Windows application data, and IBM Tivoli Storage Manager for Advanced Copy Services (TSM for ACS) that protected AIX application data.
The new product has some excellent advantages. FlashCopy Manager offers application-aware backup of LUNs containing SAP, Oracle, DB2, SQL server and Microsoft Exchange data. It can support IBM DS8000, SVC and XIV point-in-time copy functions, as well as the Volume Shadow Copy Services (VSS) interfaces of the IBM DS5000, DS4000 and DS3000 series disk systems. It is priced by the amount of TB you copy, not on the speed or number of CPU processors inside the server.
Don't let the name fool you. IBM FlashCopy Manager does not require that you use Tivoli Storage Manager (TSM) as your backup product. You can run IBM FlashCopy Manager on its own, and it will manage your FlashCopy target versions on disk, and these can be backed up to tape or another disk using any backup product. However, if you are lucky enough to also be using TSM, then there is optional integration that allows TSM to manage the target copies, move them to tape, inventory them in its DB2 database, and provide complete reporting.
Yup, that's a lot to announce in one day. And this was just the disk-related portion of the launch!
I saw this as an opportunity to promote the new IBM Tivoli Storage Manager v6.1 which offers a variety of new scalability features, and continues to provide excellent economies of scale for large deployments, in my post [IBM has scalable backup solutions].
"So does TSM scale? Sure! Just add more servers. But this is not an economy of scale. Nothing gets less expensive as the capacity grows. You get a more or less linear growth of costs that is directly correlated to the growth of primary storage capacity. (Technically, it costs will jump at regular and predictable intervals, by regular and predictable and equal amounts, as you add TSM servers to the infrastructure--but on average it is a direct linear growth. Assuming you are right sized right now, if you were to double your primary storage capacity, you would double the size of the TSM infrastructure, and double your associated costs.)"
I talked about inaccurate vendor FUD in my post [The murals in restaurants], and recently, I saw StorageBod's piece, [FUDdy Waters]. So what would "economies of scale" look like? Using Scott's own words:
Without Economies of Scale
"If it costs you $5 to backup a given amount of data, it probably costs you $50 to back up 10 times that amount of data, and $500 to back up 100 times that amount of data."
With Economies of Scalee
"If anybody can figure out how to get costs down to $40 for 10 times the amount of data, and $300 for 100 times the amount of data, they will have an irrefutable advantage over anybody that has not been able to leverage economies of scale."
So, let's do some simple examples. I'll focus on a backup solution just for employee workstations, each employee has 100GB of personal data to backup on their laptop or PC. We'll look at a one-person company, a ten-person company, and a hundred-person company.
Case 1: The one-person company
Here the sole owner needs a backup solution. Here are all the steps she might perform:
Spend hours of time evaluating different backup products available, and make sure her operating system, file system and applications are supported
Spend hours shopping for external media, this could be an external USB disk drive, optical DVD drive, or tape drive, and confirm it is supported by the selected backup software.
Purchase the backup software, external drive, and if optical or tape, blank media cartridges.
Spend time learning the product, purchase "Backup for Dummies" or similar book, and/or taking a training class.
Install and configure the software
Operate the software, or set it up to run automatically, and take the media offsite at the end of the day, and back each morning
Case 2: The ten-person company
I guess if each of the ten employees went off and performed all of the same steps as above, there would be no economies of scale.
Fortunately, co-workers are amazingly efficient in avoiding unnecessary work.
Rather than have all ten people evaluate backup solutions, have one person do it. If everyone runs the same or similar operating system, file systems and applications, this can be done about the same as the one-person case.
Ditto on the storage media. Why should 10 people go off and evaluate their own storage media. One person can do it for all ten people in about the same time as it takes for one person.
Purchasing the software and hardware. Ok, here is where some costs may be linear, depending on your choices. Some software vendors give bulk discounts, so purchasing 10 seats of the same software could be less than 10 times the cost of one license. As for storage hardware, it might be possible to share drives and even media. Perhaps one or two storage systems can be shared by the entire team.
For a lot of backup software, most of the work is in the initial set up, then it runs automatically afterwards. That is the case for TSM. You create a "dsm.opt" file, and it can list all of the include/exclude files and other rules and policies. Once the first person sets this up, they share it with their co-workers.
Hopefully, if storage hardware was consolidated, such that you have fewer drives than people, you can probably have fewer people responsible for operations. For example, let's have the first five employees sharing one drive managed by Joe, and the second five employees sharing a second drive managed by Sally. Only two people need to spend time taking media offsite, bringing it back and so on.
Case 3: The hundred-person company
Again, it is possible that a hundred-person company consists of 10 departments of 10 people each, and they all follow the above approach independently, resulting in no economies of scale. But again, that is not likely.
Here one or a few people can invest time to evaluate backup solutions. Certainly far less than 100 times the effort for a one-person company.
Same with storage media. With 100 employees, you can now invest in a tape library with robotic automation.
Purchase of software and hardware. Again, discounts will probably apply for large deployments. Purchasing 1 tape library for all one hundred people is less than 10 times the cost and effort of 10 departments all making independent purchases.
With a hundred employees, you may have some differences in operating system, file systems and applications. Still, this might mean two to five versions of dsm.opt, and not 10 or 100 independent configurations.
Operations is where the big savings happen. TSM has "progressive incremental backup" so it only backs up changed data. Other backup schemes involve taking period full backups which tie up the network and consume a lot of back end resources. In head-to-head comparisons between IBM Tivoli Storage Manager and Symantec's NetBackup, IBM TSM was shown to use significantly less network LAN bandwidth, less disk storage capacity, and fewer tape cartridges than NetBackup.
The savings are even greater with data deduplication. Either using hardware, like IBM TS76750 ProtecTIER data deduplication solution, or software like the data deduplication capability built-in with IBM TSM v6.1, you can take advantage of the fact that 100 employees might have a lot of common data between them.
So, I have demonstrated how savings through economies of scale are achieved using IBM Tivoli Storage Manager. Adding one more person in each case is cheaper than the first person. The situation is not linear as Scott suggests. But what about larger deployments? IBM TS3500 Tape Library can hold one PB of data in only 10 square feet of data center floorspace. The IBM TS7650G gateway can manage up to 1 PB of disk, holding as much as 25 PB of backup copies. IT Analysts Tony Palmer, Brian Garrett and Lauren Whitehouse from Enterprise Strategy Group tried IBM TSM v6.1 out for themselves and wrote up a ["Lab Validation"] report. Here is an excerpt:
"Backup/recovery software that embeds data reduction technology can address all three of these factors handily. IBM TSM 6.1 now has native deduplication capabilities built into its Extended Edition (EE) as a no-cost option. After data is written to the primary disk pool, a deduplication operation can be scheduled to eliminate redundancy at the sub-file level. Data deduplication, as its name implies, identifies and eliminates redundant data.
TSM 6.1 also includes features that optimize TSM scalability and manageability to meet increasingly demanding service levels resulting from relentless data growth. The move from a proprietary back-end database to IBM DB2 improves scalability, availability, and performance without adding complexity; the DB2 database is automatically maintained and managed by TSM. IBM upgraded the monitoring and reporting capabilities to near real-time and completely redesigned the dashboard that provides visibility into the system. TSM and TSM EE include these enhanced monitoring and reporting capabilities at no cost."
The majority of Fortune 1000 customers use IBM Tivoli Storage Manager, and it is the backup software that IBM uses itself in its own huge data centers, including the cloud computing facilities. In combination with IBM Tivoli FastBack for remote office/branch office (ROBO) situations, and complemented with point-in-time and disk mirroring hardware capabilities such as IBM FlashCopy, Metro Mirror, and Global Mirror, IBM Tivoli Storage Manager can be an effective, scalable part of a complete Unified Recovery Management solution.
This week, scientists at IBM Research and the California Institute of
Technology announced a scientific advancement that could be a major
breakthrough in enabling the semiconductor industry to pack more power
and speed into tiny computer chips, while making them more energy
efficient and less expensive to manufacture. IBM is a leader in
solid-state technology, and this scientific breakthrough shows promise.
But first, a discussion of how solid-state chips are made in the first place. Basically, a round thin wafer is etched using [photolithography]
with lots of tiny transistor circuits. The same chip is repeated over
and over on a single wafer, and once the wafer is complete, it is
chopped up into little individual squares. Wikipedia has a nice article
on [semiconductor device fabrication], but I found this
[YouTube video] more illuminating.
Up until now, the industry was able to get features down to 22
nanometers, and were hitting physical limitations to get down to
anything smaller. The new development from IBM and Caltech is to use
self-assembling DNA strands, folded into specific shapes using other
strands that act as staples, and then using these folded structures as
scaffolding to place in nanotubes. The result? Features as small as 6 nanometers. How cool is that?
While NAND Flash Solid-State Drives are available today, this new
technique can help develop newer, better technologies like Phase Change
Continuing my week in Chicago, for the IBM Storage Symposium 2008, we had sessions that focused on individual products. IBM System Storage SAN Volume Controller (SVC) was a popular topic.
SVC - Everything you wanted to know, but were afraid to ask!
Bill Wiegand, IBM ATS, who has been working with SAN Volume Controller since it was first introduced in 2003. answered some frequently asked questions about IBM System Storage SAN Volume Controller.
Do you have to upgrade all of your HBAs, switches and disk arrays to the recommended firmware levels before upgrading SVC? No. These are recommended levels, but not required. If you do plan to update firmware levels, focus on the host end first, switches next, and disk arrays last.
How do we request special support for stuff not yet listed on the Interop Matrix?
Submit an RPQ/SCORE, same as for any other IBM hardware.
How do we sign up for SVC hints and tips? Go to the IBM
[SVC Support Site] and select the "My Notifications" under the "Stay Informed" box on the right panel.
When we call IBM for SVC support, do we select "Hardware" or "Software"?
While the SVC is a piece of hardware, there are very few mechanical parts involved. Unless there are sparks,
smoke, or front bezel buttons dangling from springs, select "Software". Most of the questions are
related to the software components of SVC.
When we have SVC virtualizing non-IBM disk arrays, who should we call first?
IBM has world-renown service, with some of IT's smartest people working the queues. All of the major storage vendors play nice
as part of the [TSAnet Agreement when a mutual customer is impacted.
When in doubt, call IBM first, and if necessary, IBM will contact other vendors on your behalf to resolve.
What is the difference between livedump and a Full System Dump?
Most problems can be resolved with a livedump. While not complete information, it is generally enough,
and is completely non-disruptive. Other times, the full state of the machine is required, so a Full System Dump
is requested. This involves rebooting one of the two nodes, so virtual disks may temporarily run slower on that
What does "svc_snap -c" do?The "svc_snap" command on the CLI generates a snap file, which includes the cluster error log and trace files from all nodes. The "-c" parameter includes the configuration and virtual-to-physical mapping that can be useful for
disaster recovery and problem determination.
I just sent IBM a check to upgrade my TB-based license on my SVC, how long should I wait for IBM to send me a software license key?
IBM trusts its clients. No software license key will be sent. Once the check clears, you are good to go.
During migration from old disk arrays to new disk arrays, I will temporarily have 79TB more disk under SVC management, do I need to get a temporary TB-based license upgrade during the brief migration period?
Nope. Again, we trust you. However, if you are concerned about this at all, contact IBM and they will print out
a nice "Conformance Letter" in case you need to show your boss.
How should I maintain my Windows-based SVC Master Console or SSPC server?
Treat this like any other Windows-based server in your shop, install Microsoft-recommended Windows updates,
run Anti-virus scans, and so on.
Where can I find useful "How To" information on SVC?
Specify "SAN Volume Controller" in the search field of the
[IBM Redbooks vast library of helpful books.
I just added more managed disks to my managed disk group (MDG), can I get help writing a script to redistribute the extents to improve wide-striping performance?
Yes, IBM has scripting tools available for download on
[AlphaWorks]. For example, svctools will take
the output of the "lsinfo" command, and generate the appropriate SVC CLI to re-migrate the disks around to optimize
performance. Of course, if you prefer, you can use IBM Tivoli Storage Productivity Center instead for a more
Any rules of thumb for sizing SVC deployments?
IBM's Disk Magic tool includes support for SVC deployments. Plan for 250 IOPS/TB for light workloads,
500 IOPS/TB for average workloads, and 750 IOPS/TB for heavy workloads.
Can I migrate virtual disks from one manage disk group (MDG) to another of different extent size?
Yes, the new Vdisk Mirroring capability can be used to do this. Create the mirror for your Vdisk between the
two MDGs, wait for the copy to complete, and then split the mirror.
Can I add or replace SVC nodes non-disruptively? Absolutely, see the Technotes
[SVC Node Replacement page.
Can I really order an SVC EE in Flamingo Pink? Yes. While my blog post that started all
this [Pink It and Shrink It] was initially just some Photoshop humor, the IBM product manager for SVC accepted this color choice as an RPQ option.
The default color remains Raven Black.
The focus on square footage resulted in higher density. This reminds me of the classicIBM commercial ["The Heist"] where Gil panics that the roomful of servers are missing, and Ned explains that it was all consolidated ontoa single IBM server.
I suspect few people picked up on the fact that the acronym for["new enterprise datacenter"] spells "Ned", ourdonut-eating hero in these series of videos.
Costs in the data center are proportional to power usage rather than space.
Power efficiency is more of a behavior problem than it is a technology problem.
This is definitely a step in the right direction. Both servers and storage systems consume a large portionof the energy on the data center floor. IBM Tivoli Usage and Accounting Manager can includeenergy consumption as part of the chargeback calculations.
However, I have to assume his real question is ... "what is the quick and easy way for me to build a lightweight database app like Microsoft Access that I can distribute as a standalone executable?"
To which I would say "Lotus has a program called Approach, which is part of Lotus SmartSuite, which some people still use. However, a lot of the focus in IBM now centers around the lightweight Cloudscape database which IBM acquired from Informix, which is now known as the [open source project called Derby]. Many IBM and Lotus products, such as Lotus Expeditor use the JDBC connection to Derby, which allows you to use Windows, Linux, Flash, etc. ... with no vendor lock in".
I am familiar with Cloudscape, and I evaluated it as a potential database for IBM TotalStorage Productivity Center, when I was the lead architect defining the version 1 release. It runs entirely on Java, which is both a plus and minus. Plus in that it runs anywhere Java runs, but a minus in that it is not optimized for high performance or large scalability. Because of this, we decided instead on using the full commercial DB2 database instead for Productivity Center.
Not to be undone, my colleagues over at DB2 offered a different alternative, [DB2 Express-C], which runs on a variety of Windows, Linux-x86, and Linux on POWER platforms. It is "free" as in beer, not free as in speech, which means you can download and use it today at no charge, and even ship products with it included, but you are not allowed to modify and distribute altered versions of it, as you can with "free as in speech" open source code, as in the case of Derby above (see [Apache License 2.0"] for details).
As I see it, DB2 Express-C has two key advantages. First, if you like the free version, you can purchase a "support contract" for those that need extra hand-holding, or are using this as part of a commercial business venture. Second,for those who do prefer vendor lock-in, it is easyto upgrade Express-C to the full IBM DB2 database product, so if you are developing a product intended for use with DB2, you can develop it first with DB2 Express-C, and migrate up to full DB2 commercial version when you are ready.
This is perhaps more information than you probably expected for such a simple question. Meanwhile, I am stilltrying to figure out MySQL as part of my [OLPC volunteer project].
Well, we had another successful event in Second Life today.
Unlike our April 26 launch of our System Storage products for IBM Business Partners only, this time we decided this time to make it as a "Meet the Storage Experts" Q&A Panel format, and open up registration to everyone. Thesubject matter experts sat at the front of the room on four stools. We had six rows of chairs arrangedsemi-circularly.
Shown above, from left to right, are the avatars of our four experts:
IBM System Storage N series, focusing on recent N3000 disk system announcements
Harold Pike (holding the microphone while speaking)
IBM System Storage DS3000 and DS4000 series, focusing on recent DS3000 disk system announcements
IBM System Storage TS series, focusing on recent TS2230, TS3400 and TS7700 tape system announcements
IBM storage networking, focusing on recent IBM SAN256B director blade announcements
While Eric was a veteran Second Lifer, having presented at our April event, the other three were trainedon how to raise their hand, speak into the microphone, sit on the stool, and so on. I want to thank allof our experts for putting in this effort!
The event was produced by Katrina H Smith. She did a great job, and made sure we were on top ofall the issues and tasks required to get the job done. Running a Second Life event is every bit ashard as running a real face-to-face event. We had several meetings to discuss venue details, placementof chairs, placement of product demos, audio/video recording, wall decorations, tee-shirt and coffee mug design, logistics, and so on.
I acted as moderator/emcee for the event. That is my back in the picture above. The process wassimple, modeled after the "Birds of a Feather" sessions at events like SHARE and the IBMStorage and Storage Networking Symposium. We threw out a list of topics the experts would cover,and people in the audience would "raise their left hand". I, as the moderator, would then walkover to each person, and hold out the microphone for them to ask the question. I would then repeat the question and ask the appropriate expert to provide an answer. We defined gestures onhow to "raise hand" and "put hand down" that we gave to each registered participant.
We had four dedicated "camera-avatars" in world to capture both video and screenshots.Our video editors are now working to edit "highlight videos" that we can use at future events, for training materials, and for our internal "BlueTube" online video system.
The room was filled with examples of each of our products, made into 3D objects that were dimensionallycorrect, and "textured" with photographs of the actual products. If you click on an object, you get a "notecard" that provided more information. Special thanks to Scott Bissmeyer for making all of theseobjects for us.
We made posters of each expert and placed them in all four corners of the room. On the bottom of each coffee mug was a picture of each of the experts, and if you walked under each of the posters, you were"dispensed" a coffee mug matching the expert shown in the poster.Participants could "Collect all Four!" When you bring the coffee mug up to takea sip, the picture on the bottom of the mug is exposed for all to see.And as a final give-away to the audience, we made a variety of event tee-shirts and polo-shirts.
At the end of the session, we asked everyone to click on the "Survey" kiosk near the exit door. We askedsix simple questions using SurveyMonkey.com that took only a fewminutes to process. We found asking questions immediately at the end of the event was the best way tocapture this feedback.
From a "Green" perspective, we had people registered from the following countries: US, India, Mexico,Australia, United Kingdom, Brazil, Germany, Argentina, Chile, China, Canada, and Venezuela. Second Lifeallows all these people who probably could not travel, or could not afford the time and expense to travel,to participate in a simulated face-to-face meeting without energy consumption of traditional travel methods.
More importantly, we got several leads for business. People often ask "Yes, but is there any businessassociated with this?" This time, there was, based on the answers to the questions, several avatars asked for a real sales call to follow-up on the products and offerings they were discussed.
With such a great success, we have already scheduled our next Second Life event, November 8. Mark your calendars! I'll postmore details on the registration process of the November event when available.
This week, I am presenting at the IBM Systems Technical University for IBM Storage and POWER Systems. This conference is being held in New Orleans, Louisiana, October 16-20, 2017, at the beautiful Hyatt Regency. There were about 800 clients attending.
This is my recap for the last few sessions before I left town, spanning Tuesday afternoon and Wednesday afternoon.
Reasons why IBM hyperconverged systems powered by Nutanix surpass other HCI from HPE, Cisco and more
Rob Simpson, Senior Strategic Marketing Manager at Nutanix, presented Nutanix hyperconverged systems. Nutanix runs on both x86 and POWER. For x86, it supports VMware, Microsoft Hyper-V, and Citrix XenServer, as well as their own Acropolis Hypervisor (AHV) derived from Linux KVM. For POWER, it uses AHV re-compiled for POWER chip set.
Hyperconverged systems can be sold in full rack configurations, as individual appliances, or as software that can be deployed on your own servers. Rob compared Nutanix against three competitive appliances: Dell EMC VxRAIL based on VMware VSAN, HPE Simplivity, and Cisco HyperFlex.
Everything you wanted to know about IBM Spectrum Scale metadata but didn't know to ask
Eric Sperley, IBM Software Defined Infrastructure Architect, presented the internal metadata structures used in IBM Spectrum Scale.
Why, oh why, did I attend this presentation? I had worked on Spectrum Scale back when it was called GPFS over 15 years ago, and thought I already knew everything about "inodes" that I ever wanted to, but Eric proved me wrong!
"Laws, like sausages, cease to inspire respect in proportion as we know how they are made."
--John Godfrey Saxe
A lot has changed! There have been a lot of improvements to the internal structures to improve parallel I/O performance, and reduce latency of administrative tasks.
IBM Spectrum Scale can be divided into different file systems, each of which can be configured with different performance characteristics and block size, such as random small files for scanned images, versus large sequential files for streaming videos.
My presentation was nowhere near as technical as Eric's above. I provided an overview of how IBM Spectrum Scale is configured, how it works, and how it interacts with IBM Cloud Object Storage System, Spectrum Protect, and System Archive.
I also covered the latest GSxS and GLxS models of the Elastic Storage Server, or ESS for short. These models provide awesome performance at low cost. The GSxS models are all-flash arrays for high performance. The GLxS models are hybrid with 2 Solid-State Drives and the rest NL-SAS 7200 rpm spinning disk for high capacity.
IBM COS new features
Andy Kutner, IBM Channel and Alliances Architect, presented the latest features in IBM Cloud Object Storage, IBM COS for short.
Cloud Enabled Vaults, or CEV for short, offer Non-Erasable, Non-Rewriteable (NENR) tamperproof protection for objects. Objects written to a CEV vault can not be deleted or replaced with newer versions, for a specific retention period.
(Note: Some folks mistakenly use the term "Write Once, Read Many" (WORM) for this. WORM applies only to tape, optical, paper tape, punched cards, and non-erasable ROM chips. For this reason, the term "Non-Erasable, Non-Rewriteable" (NENR), used in the U.S. Securities Exchange Commission (SEC 17a-4) regulation, has been created to extend this tamperproof protection to flash, disk and cloud-based storage architectures.)
The entry-level systems lowers the minimum capacity of systems. Before, IBM recommended at least 500 TB capacity to consider IBM COS. Now, the combination of embedded Accessers and Concentrated Dispersal mode, can lower the starting point to as low as 72 TB, but still allow you to grow to multiple PBs.
This week, I am presenting at the IBM Systems Technical University for Storage and POWER Systems. This conference is being held in New Orleans, Louisiana, October 16-20, 2017, at the beautiful Hyatt Regency.
This is my recap for sessions on Day 2 morning.
FlashSystem A9000 and A9000R Overview
Andy Walls, IBM Fellow, CTO and Chief Architect,and Brent Yardley, IBM STSM and Master Inventor, co-presented this session. This was the "deep dive" of the A9000/R, a basic continuation of the one they did yesterday.
The Pendulum Swings Back -- Understanding converged and hyperconverged integrated systems
With IBM's partnership with Nutanix, this has become a particularly popular topic. I cover the last 50 years of storage evolution, from internal storage and external storage to NAS and SAN storage networks.
More recently, people have been willing to give up all those gains for something simpler, less powerful, less reliable, less expensive. Enter Converged and Hyperconverged Systems. IBM PureSystems and VersaStack lead the pack for Converged Systems, along with IBM Spectrum Scale, Spectrum Accelerate and Nutanix on IBM Power Systems for Hyperconverged Integrated Systems.
New Generation of Storage Tiering -- Less Management, Lower Costs, and Improved Performance
There are orders of magnitude between the fastest All-Flash Array and the least expensive tape storage. Ideally, there would be a "slider bar" that allowed people to select from the fastest to the least expensive. IBM offers a variety of solutions to offer this "slider bar", with automation to move data as needed between tiers.
I start with IBM Easy Tier, available on DS8000 and Spectrum Virtualize products, to IBM Virtual Storage Center where advanced analytics moves data to the right location, to IBM Spectrum Scale which provides the ultimate tiering, across multiple locations, between flash, disk and tape.
The lunches at these conferences are amazing, but then the "Big Easy" is known for its food!
This week, I am presenting at the IBM Systems Technical University for Storage and POWER systems. This conference is being held in New Orleans, Louisiana, October 16-20, 2017, at the beautiful Hyatt Regency.
The afternoon sessions on Monday were all about Cloud.
Back in 2009, I was designated the IBM Cloud Storage Center of Competency for all of the IBM Systems client centers. That was nearly a decade ago, and I am still talking about Cloud Storage!
Since then, IBM has decided to be a "Cloud Platform" company, and now everyone wants to know about Cloud Storage. Cloud is not just to lower costs, as it once start out as, but now for innovation and business value.
Nearly all of IBM Storage is enabled for cloud, from our high-end FlashSystem, DS8000 and XIV flash and disk storage arrays, to our Spectrum Storage software suite, to our various tape products.
Building Private Cloud with Ubuntu and OpenPOWER
Ivan Dobos, from Canonical--the company that makes Ubuntu--presented Ubuntu on OpenPOWER. Other Linux distributions like Red Hat and SuSE distributions offer both a "community supported" version (OpenSUSE or CentOS), and an "enterprise version" (SLES and RHEL). Ubuntu doesn't fork their versions, they have a single version for everyone.
Ubuntu 14.04 LTS was made available as a Little-Endian distribution for IBM POWER and OpenPOWER. Ubuntu was the first Linux distribution to support CAPI and PowerKVM for the POWER8 platform.
(A note on release numbers. Ubuntu releases every April and October, so 14.04 represents 2014/April release. Every two years, a release is designated "Long Term Support" (LTS) which is supported for five years.)
Since version 16.04, Ubuntu offers the LXD Container Hypervisor, based on LXC, similar to Solaris Zones, but running as a daemon. Virtual Machines are heavy because they have their own kernel. Containers instead use the kernel of the underlying hypervisor, but limited to Linux guests. The Linux guests are can be older versions of Debian, Red Hat or SuSE, but with the latest, most secure kernel of Ubuntu for safety and security.
(Canonical gives Ubuntu away for free, but offers "Enterprise Services" for a fee to companies that want this added level of support. One of the features with Enterprise Services is "Live Kernel Update". Normally, updating the Linux kernel requires a reboot, which would cause outage to all of the VMs and containers running on that host server.)
Like VMs, you can launch containers, switch to bash shell, install software, run applications, and shut down containers, all isolated from other containers. The LXD daemon can run LXC and Docker containers. Some advantages of doing this:
Lift and Shift, live mobility from one system to another
Collocation of different workloads on same node
More efficient to use containers than Virtual Machines
14x greater density with LXD than traditional KVM or VMware (tested on x86)
Based on open source LXC containers
Ubuntu is designed for the "Elastic Hybrid Cloud". Canonical recommends combining on-premises data center with two or more public cloud providers. Scarcity has shifted from "code" to "operations". Are you ready to run applications you don't understand?
Total Cost of Ownership is shifting from code license costs to operational costs. Canonical offers a free, downloadable, operations orchestration platform called "Juju" to help install, configure and scale applications. Juju means "magic" in Swahili.
Scripts on Juju are called charms. There are Juju charms to install and configure things like MongoDB and IBM Spectrum Scale. Furthermore, Juju charms can be bundled together for more complicated deployments.
Juju is not limited to LXD, can be used with VMware, OpenStack, bare metal servers, and public clouds. It is available on Ubuntu, Red Hat and Windows. As a demo, Ivan built an entire working OpenStack environment, with 20 applications on 4 bare metal servers, all installed and launched with Juju.
For OpenStack, you can use the basic "Ubuntu OpenStack", or a more complete "Canonical OpenStack", or even have Canonical folks manage your environment for you.
Canonical MaaS (Metal-as-a-Service) uses hardware APIs to manage bare metal servers, providing physical provisioning, dynamic allocation for workloads, and even Ubuntu and CentOS operating system installs. Canonical has clients with over 100,000 servers managed with MaaS.
Introduction to IBM Cloud Object Storage System and its applications (powered by Cleversafe)
Before 2015, IBM offered two "Object Storage" products: IBM Spectrum Scale and IBM Spectrum Archive, and I was constantly having to compare and contrast IBM products to Cleversafe.
Not any more! With the IBM acquisition of Cleversafe, IBM now offers all three!
This session explained all of the features and functions of IBM Cloud Object Storage System, available as software, as pre-built systems, including a VersaStack CVD, and as Storage-as-a-Service (STaaS) in the IBM Cloud.
(IBM renamed Cleversafe DSnet to "IBM Cloud Object Storage System". I joked that if IBM ever acquired Coca-Cola, they would probably rename their signature soft drink as the "Brown Carbonated Sugar Liquid", or BroCarb SugarLiq for short!)
In the evening, we had a nice reception with food and drink at the Solution Center. The Solution Center has booths where all of the IBM and Business Partners have their experts answering questions and handing out brochures of their offerings.
This week, I am presenting at the IBM Systems Technical University for Storage and POWER Systems. This conference is being held in New Orleans, Louisiana, October 16-20, 2017, at the beautiful Hyatt Regency.
Storage: Opening Keynote Session
Clod Barrera, IBM Distinguished Engineer and Chief Technical Strategist, and Craig Nelson, Brocade, co-presented this session.
Clod Barrera presented the latest in Storage trends. He organized his talk around four layers: Infrastructure, Storage Management, Storage Systems, and Storage Media.
Craig Nelson presented the changes in Storage Networking. With advancements in both server and storage bandwidth, the storage network becomes the bottleneck. Insane flash storage performance requires insanely fast storage networks. IBM offers Brocade-manufactured switches and directors that now support 32Gbps. Combining four paths together, these can offer Interswitch Connection Links (ICL) at 128 Gbps.
The Seven Tiers of Business Continuity and Disaster Recovery
With the recent Hurricans Harvey, Irma, Jose, and Maria, my topic on Business Continuity and Disaster Recovery (BC/DR) was well attended. I have been working in BC/DR for most of my career, including the "High Availability Center of Competency" or HACOC.
Back in 2005, I was here in New Orleans, the week before Hurricane Katrina, for the IBM Storage Symposium, August 22-26, the predecessor of this conference. I left on Friday, August 26, and the storm hit that weekend.
I met with people photographing all the buildings, in hopes to sell "before pictures" to insurance companies and filmmakers after the hurricane hit. Film director Spike Lee bought much of this footage. Smart!
However, natural disasters like hurricanes, tornados and floods represent less than 20 percent of all discasters. The majority of disasters, nearly 75 percent, arise from electrical power outages, human error, system failure and randsomware.
IBM FlashSystem Overview
Andy Walls, IBM Fellow, CTO and Chief Architect,and Brent Yardley, IBM STSM and Master Inventor, co-presented this session. Andy started with FlashSystem 900, V9000 and A9000/R.
The room was packed with standing room only, and Andy was answering so many questions that he never finished his portion, and Brent Yardley never had a chance to cover his portion.
Fortunately, there were "deep dive" sessions on FlashSystem 900, V9000 and A9000/R later in the week, so Andy suggested everyone go to lunch and attend these other more detailed sessions.
Tomorrow, I will be presenting at the STU Orlando for Storage and Cognitive Systems (formerly POWER servers). This conference will be held in New Orleans, Louisiana, October 16-20, 2017.
Here is my speaking schedule:
The Seven Tiers of Business Continuity and Disaster Recovery (BC/TR)
IBM's Cloud Storage Options
Introduction of IBM Cloud Object Storage System and its Applications (powered by Cleversafe)
The Pendulum Swings Back -- Understanding Converged and Hyperconverged Integrated Systems
New generation of storage tiering: Simpler management, lower costs, and increased performance
Introduction of IBM Cloud Object Storage System and its Applications (powered by Cleversafe) **repeat**
IBM Spectrum Scale for File and Object storage
If these topics seem familiar, I have presented them at prior events earlier this year, including the STU Orlando in Orlando Florida, and the one in Melbourne Australia. However, I have made updates! New products have been announced!
If you are planning to attend, here are some of my past blog posts to help you get up to speed:
STU Orlando - Orlando, Florida
This event was a large 5-day event to replace the technical portion of IBM's previous "Edge" conference.
This event was a smaller 3-day event to bring STU to other countries. We used to call these "Edge Comes to You" events, but now we call them "IBM Systems Technical University" just like the ones in the USA.
The STU at New Orleans will be a 5-day event. Instead of a "Meet the Experts" session, they are having a "Poster Session" in its place. Many of the posters will have QR codes, so make sure you have a "QR Scanner" application installed on your smartphone so you can scan them quickly!
Everyone, speakers and attendees alike, should consider making a QR code for themselves for this event. Go to [any number of websites] that generate a QR code. This could a VCF file with all of your contact information, a link to your blog or website, or point to your presentations on Slideshare or IBM@Box.
The next time someone at the event asks for this information, display the QR code on your smartphone, and let them scan it. Alternatively, you can send the image via MMS text message.
(My QR Code is fully functional, go ahead and practice scanning it with your smartphone for practice!)
I arrive in to New Orleans Sunday afternoon, so if you are in town, give me a shout! Or tweet me at @az990tony
IBM introduces the eight generation of Linear Tape Open (LTO) tape drive technology, with corresponding support in all of the IBM tape libraries.
Fellow blogger Jon Toigo, of Drunkendata.com fame, came to Tucson to interview Lee Jesionowski, Ed Childers, Calline Sanchez, and me about this. Check out the various segments on YouTube or his website.
The LTO-8 cartridges are not yet available, but when they are, they will hold 12 TB raw capacity, or 30 TB effective capacity at 2.5-to-1 compression ratio. The new drives are N-1 compatible to read/write LTO-7 cartridge media.
Previous generations also supported reading N-2 generation tapes, LTO-8 breaks from that tradition and will not support LTO-6 cartridges at all.
LTO-8 comes in both "Full Height" (FH) and Half-Height (HH) models. The FH models can transfer data at 360 MB/sec (or 900 MB/sec effective at 2.5-to-1 compression), and the HH models at 300 MB/sec (or 750 MB/sec effective at 2.5-to-1).
LTO-8 supports IBM Spectrum Archive and the "Linear Tape File System" (LTFS) tape format for self-describing long-term retention of data.
Compliance storage has come under many names. For tape and optical media, we had "WORM" for Write-Once, Read-Many. For disk-based storage, we had "Fixed-Content" or "Content-Addressable Storage". For file systems, we had "Immutable Storage".
Fortunately, the clever folks who crafted the SEC 17a-4 law came up with an umbrella term: "Non-Erasable, Non-Rewriteable" (NENR) that covers all storage media, from WORM tape and optical, to tamperproof flash, disk and cloud-based solutions.
The other major change is "Concentrated Dispersal" mode, or "CD mode" for short. Erasure Coding works best when data is dispersed across three or more sites. When this happens, you can lose all of the data at one site, and still have 100 percent access to all data from the other locations.
IBM's "Information Dispersal Algorithm", or IDA for short, scattered slices of data across many servers. Great for high availability and performance, but often meant that the minimum deployment was 500TB or greater.
Not every organization is ready for such a large purchase. Some want to just [dip their toe in the water] with something smaller, less expensive. Well IBM delivered!
The new CD mode means that instead of one slice per Slicestor node, you can pack lots of slices on each node. Each slice will be on distinct disk drives, for high availability.
Entry-level configurations now can be as little as 72-104 TB, across 1, 2 or 3 sites.
Next month, I will be presenting at the IBM Systems Technical University for Storage and POWER. This conference will be held in New Orleans, Louisiana, October 16-20, 2017.
Instead of a "Meet the Experts" Q&A panel, this event will feature a "Poster Session". I had the pleasure of doing one of these down in Melbourne, Australia last month. For those who missed it, here are my blog posts:
By now, you have already decided on a title and abstract of your poster. You will need to figure out a quick and easy way to explain your poster, and as always, shorter is better. It reminds me of a famous quote:
"Sorry this letter is too long...
If I had more time, I could have made it shorter!
-- Blaise Pascal
The event team asked me to write some instructions on the mechanics of how to put together a poster for this, since it is new for many people. I use Microsoft PowerPoint 2013 and ImageMagick tools to accomplish this.
Arrangement of Slides
Posters for the IBM Systems Technical University in New Orleans will be 24x36 inches in size. If you print out your poster in 8.5x11 inch standard size letter pages, that would be eight slides, 2 columns, 4 rows. This leaves one inch border all around.
The event will provide both the foam board and double-sided sticky tape. You can bring your poster as a stack of Letter-sized pages in a folder, and assemble your poster at the event.
You can increase the size of individual image to 17x22, to offer the "Big Picture" view. Basically, we can take a standard 8.5x11 Letter size page, expand it onto four separate pages, and then put them on the poster! I will show you how in the steps below.
Lastly, you can have two big slides. If your poster is organized as "Before/After" or "Problem/Solution" then this arrangement could be perfect for you.
Setting Custom Paper Size on PowerPoint
In Melbourne, I had to use European A4 standard paper, and had to figure out how to do this in PowerPoint. I was surprised to learn that the PowerPoint default is 4:3 ratio of 10x7.5 inch, and that this is stretched to be whatever paper size you print on.
The difference is slight, but I prefer [WYSIWYG], so we will change the slide to "Custom size" and force it to 8.5x11 inches, with "Landscape" orientation. This will avoid anything looking stretched or squished on the big poster.
Converting a PowerPoint Slide to PNG Image file
If you would like to resize one or more of your PowerPoint slides, you will need to save those slides as images. Select "File" and "Save As" and as the format, choose "PNG" format. You can also select GIF or JPG, but I prefer PNG.
You can export all of your slides as images, in which case it will create a folder and number each slide individually. Or, you can select "Just This One" for the current slide.
By default, it will use the same name as your PPT file, just change the extension to PNG. I suggest you name the file something meaningful to you. In my examples below, I use "small.png" as the file name.
I am using PowerPoint 2013, which defaults to 96 dpi. So, an 8.5x11 paper becomes 1056x816 pixels in size.
If you have PowerPoint 2003 or higher, you can change the Windows registry to specify image resolutions. Not recommended for the faint of heart. Or anyone else. But here's the deal if you want to try (if the following doesn't make any sense, it might be better not to mess with the registry):
Quit PowerPoint if it's running
Navigate to HKEY_CURRENT_USER\Software\Microsoft\Office\X.0\PowerPoint\Options
(For X> above, substitute 16.0 for PowerPoint 2016, 15.0 for PowerPoint 2013, 14.0 for PowerPoint 2010, 12.0 for PowerPoint 2007 and 11.0 for PowerPoint 2003.
Add a new DWORD value named ExportBitmapResolution and set its DECIMAL value to the DPI value you want (for example, 300 means 300 dots per inch)
Close REGEDIT, start PowerPoint and test. Your files will be 3300x2550 pixels instead.
Since the resulting four pieces are exactly the size of a page, you can put them back into your PowerPoint deck. Create four blank slides, select Insert then Pictures. Insert each picture (big_0.png, big_1.png, big_2.png, and big_3.png) as a separate page.
You can print this out, and bring with you to the event, or send it to someone to have them print for you.
Upload files to IBM@Box
This next step is completely optional, but found it adds a nice touch. As an IBMer, you can upload your presentation, and any documents, whitepapers or other materials, to [IBM@Box]. Create a directory that is unique to you, such as your last name and the conference. For example, I have "Pearson-STU-NOLA-2017" as my folder name.
You can create a "URL Link" to this folder. Select "Share", then "Share Link" to create a dialog box. It is important to specify "People with this link" if you want those outside of IBM, such as clients and IBM Business Partners, to have access.
Press the little "gear" button on the upper right, and it gives you options to customize the URL. Normally the URL is some long random sequence of characters, but you can rename it to something meaningful and easier to remember.
Generate a QR Code
Since you have a URL Share Link for your files on IBM@Box, you can generate a QR Code for this link, and include on your poster!
There are several online websites that can generate a QR Code for free. I use [QRme.com] in this example. Go to the website, copy in the URL, and press "Generate" button.
The QR Code is generated successfully, right click and "Save Image" to a file on your hard drive. This image can be inserted as a picture like we did above onto any slide. You can resize as needed.
In Melbourne, one of the posters had the QR Code at the top, with the Title, and it was impossible to see, so difficult to use a smartphone to scan the information. For this reason, I recommend putting the QR code in the lower right corner of your poster. Between shoulder and waist height for the audience, to be comfortable to scan.
I am looking forward to going back to New Orleans to speak at this conference!
Well, it's Tuesday again, and you know what that means? IBM Announcements!
IBM announced a new product, IBM Spectrum Protect Plus. To understand why, I will need to discuss a bit of history related to Data Protection.
(FCC Disclosure: I work for IBM. This blog post can be considered a "paid celebrity endorsement" for IBM Spectrum Protect, IBM Spectrum Protect Snapshot, IBM Spectrum Protect for Virtual Environments, and IBM Spectrum Copy Data Management products. I was not paid in any manner to promote Geoffrey Moore's book mentioned below.)
IBM Spectrum Protect was originally developed as the Workstation Data Save Facility (WDSF) back in the 1980s, back when Personal Computers were just getting deployed.
I started in 1986 developing mainframe software, so we all had bulky 3270 terminals. When our area was offered 120 PCs to replace them, I was tasked with determining how to roll these out, 24 at a time, over five months.
My job was to determine who would get a PC in the first round, the second round, and so on. I handed out a simple one-page survey, asking everyone basic questions. Are you familiar with Personal Computers? Do have one at home? Are you comfortable using a mouse? My plan was to give those most familiar with them sooner, and those less familiar in later rounds.
However, it was my final question that sealed the deal:
How soon do you want a PC to replace your 3270 terminal?
[ ]Immediately [ ]Next month [ ]No Hurry [ ]Put me last [ ]Never!
Surprisingly, I had roughly 24 folks choosing each option on this last question, which made my decision process easy for me!
(In his book Crossing the Chasm, fellow author Geoffrey Moore would come up with similar groups: Innovators, Early Adopters, Early Majority, Late Majority, and Laggards. This is a great book and I highly recommend it!)
Of course, we used WDSF to back up the files. WDSF would later morph into DFDSM, then ADSM, then TSM, and now it is called IBM Spectrum Protect.
Over the decades, the product has evolved from just backing up data on personal computers. IBM Spectrum Protect can now protect all kinds of machines, from tablets, mobile devices, and smartphones, to virtual machines, databases, and application servers in the data center.
Besides creating backup versions of files, IBM Spectrum Protect can also migrate older, less frequently used files to less expensive media, as well as archive files for long-term retention.
Different files can be assigned to different "management classes" that determine policies to be applied and enforced on the backup, migration and archive copies. For backups, this includes how many versions to keep while the file exists, how many versions to keep after the original file is deleted, how long to keep those inactive versions.
Instead of a grandfather-father-son [backup tape rotation], full-plus-incremental, or full-plus-differential scheme employed by other backup software, IBM Spectrum Protect has a unique "Incremental-Forever" approach that reduces backup time, LAN bandwidth requirements, and backup storage media.
While most companies still backup to tape, IBM Spectrum Protect can backup to flash, disk, tape, virtual and physical tape libraries, object storage, and even to public Cloud Service Providers such as IBM Bluemix, Amazon S3, and Microsoft Azure.
IBM Spectrum Protect both client-side and server-side data footprint reduction technologies including compression and deduplication, eliminating the need for expensive, single-purpose data deduplication devices like Dell-EMC Data Domain.
IBM Spectrum Protect is recognized as a leader in Data Protection software, able to scale up to meet the demands of the largest enterprises. However, the parameters and options that IBM Spectrum Protect has acquired over time have been compared to the cockpit or flight deck of an airplane!
For clients with Virtual Machines, IBM offered three solutions:
IBM Spectrum Protect Snapshot
Formerly called Tivoli Storage FlashCopy Manager (FCM), [IBM Spectrum Protect Snapshot] takes frequent, near-instant, non-disruptive, application-aware backups and restores for SAP, Oracle and Db2. It can also be used for VMware using advanced snapshot technology, on both IBM and non-IBM storage systems.
IBM Spectrum Protect Snapshot can be used as a stand-alone product, or integrated with IBM Spectrum Protect to move the snapshots and FlashCopy targets to other storage media.
IBM Spectrum Protect for Virtual Environments (VE)
Formerly called IBM Tivoli Storage Manager for Virtual Environments, [IBM Spectrum Protect VE] protects both VMware and Microsoft Hyper-V virtual machines.
IBM Spectrum Protect VE safely moves backup workloads to a centralized IBM Spectrum Protect server and enables administrators to create backup policies or restore virtual machines with just a few clicks. It allows you to protect data without a traditional backup window.
IBM Spectrum Copy Data Management makes copies available to DBAs, Developers and VM administrators when and where they need them. While this product is focused on DevOps and Dev/Test workflows, it can also be used to automate and schedule snapshots that can serve as backups.
Surprisingly, many companies do not take advantage of these solutions. Even clients who already have IBM Spectrum Protect deployed either (a) simply use Spectrum Protect clients on individual VM guests, or (b) use third-party products to backup VMs outside of Spectrum Protect infrastructure.
"Problems cannot be solved with the same mind set that created them."
-- Albert Einstein
Smaller clients want something simpler to deploy, and easier to use and administer. Rather than simplify the products above, a process called "kneecapping" in the IT industry, IBM opted for a clean slate, [start-from-scratch] approach.
The result is IBM Spectrum Protect Plus, new software that was preview announced last Wednesday in time for this week's VMworld 2017 conference in Las Vegas, and next month's VMworld conference in Barcelona, Spain.
IBM Spectrum Protect Plus is available as either a stand-alone product, or integrated with IBM Spectrum Protect for long-term protection. It is focused exclusively on VMware and Hyper-V environments. General Availability is expected some time in 4Q 2017.
Key features include:
Simple to install in less than 15 minutes, configured in an hour
Easy to use by DBA, VM or application administrator. No IBM Spectrum Protect skills required for stand-alone deployment
Pre-defined Gold, Silver and Bronze policies are ready to use. Additional customized policies can be configured as needed
Supports both application-aware and crash-consistent methods
Data Footprint Reduction technologies including compression and deduplication
Instant data recovery to support DevOps, Dev/Test, Reporting, Analytics and Training
Granular search and restore of entire Virtual Machines, VMDKs, and individual files
As for the name, I would have prefered "IBM Spectrum Protect Basic Edition". The "Plus" implies that the new product is more advanced, or offers more features, than the existing Spectrum Protect editions.
Well, it's Tuesday again, and you know what that means? IBM Announcements!
Enhanced Spectrum Virtualize software
IBM announces v8.1 of the Spectrum Virtualize software that works with the latest models of SAN Volume Controller, Storwize and FlashSystem V9000 products.
This v8.1 release will not support older hardware. For these older models, continue to use v7.8.1 release until end of service and support:
SAN Volume Controller, CF8 and CG8 models
FlashSystem V840, AC0 model
Storwize V7000 Gen 1, models 1xx, 2xx and 3xx
Storwize V5000 Gen 1, models 24 C/E, 12 C/E
Storwize V3500 and V3700, all models
Hot Spare Node
Higher availability provided by automatically swapping a spare node into the cluster if the cluster detects a failing node. Following the N-port ID Virtualization (NPIV) features introduced in previous release, this new feature is available for SVC and FlashSystem V9000.
Spare nodes can also be extremely helpful with code updates and node refreshes. Update the code load on a spare node, and use this to roll forward the other nodes. In this manner, you are never in "single node" mode!
You can have up to four spare nodes per SVC cluster, and three spare nodes per FlashSystem V9000 cluster. These spares are "site-aware" to support Enhanced Stretch Cluster and HyperSwap configurations.
This feature requires Fibre Channel switches, so it won't work if you are using direct-attached SAS, iSCSI or FC point-to-point connections.
256 GB memory support
Spectrum Virtualize will now take full advantage of system memory, rather than just the first 64 GB. A fixed 12 GB is set aside for write cache, the rest is used for operating system code, read cache, and compression work space.
IBM supports up to 128 GB per canister on the Storwize V7000 Gen2+ models, and up to 256 GB for SAN Volume Controller SV1 and FlashSystem V9000 models.
One two-socket nodes, IBM previously dedicated specific cores to perform I/O operations, and others for Real-time Compression. With v8.1 release, the team implemented a more sophisticated multi-socket, multi-core, multi-threaded approach. Internal tests showed this improved performance 36 to 50 percent on SAN Volume Controller DH8 and SV1 models.
Enhancements for Encryption
IBM Security Key Lifecycle Manager (SKLM) support has been expanded to support up to three Key Server clones for a total of four Key Servers (one master and three clones).
You can use both central key management (SKLM servers) and local key management(using USB keys physically attached to the back of the controllers) at the same time. This can be useful to transition from one method or another, or use both concurrently for added flexibility.
Both SKLM and USB-based keys can also be used to encrypt FlashCopy targets written to the Cloud with Transparent Cloud Tiering.
Remote support assistance
IBM support engineers can perform system or upgrade recoveries over secure support sessions. This enables remote concurrent upgrades to be done securely and is only available only for clients who purchase Enterprise Class Support.
Since you are already sending periodic inventory updates as part of "call home" support, you might as well let IBM review the configuration and provide customized recommendations!
There is no additional cost, and this provides an additional review to catch any potential problems, single points of failure, or other issues that could be a problem later on.
Based on the success of the Hyper-Scale Manager GUI developed for the FlashSystem A9000, the new Spectrum Virtualize GUI offers an updated look and feel, with new fonts, colors, banner, navigation, dashboard, and other interactive elements.
New Pause Feature for Concurrent Code Update (CCU)
The Pause function will allow users to pause CCU indefinitely. This pause allows customers to do any problem determination, such as multi-pathing issues, or simply to pause the upgrade, take a break for lunch, then resume the upgrade when convenient to do so.
There were also enhances to the hardware models themselves.
IBM FlashSystem V9000
The IBM FlashSystem V9000 has two enhancements. First, there is an option to add a pair of AC3 nodes without AE2 enclosures to scale performance.
The second is the ability to add a single AC3 node for use as a hot spare node. You can have up to three of these extra AC3 spares per V9000 cluster.
IBM Storwize V7000
IBM Storwize V7000 Gen2+ offers increased cache of up to 256 GB per controller, 128 GB per canister. This follows on the heels of the recent increase to 256 GB per node for the SAN Volume Controller and FlashSystem V9000. More memory means more cache hit ratios for faster performance, and more compressed volumes.
900 GB 15K rpm 2.5-inch SAS drive
IBM SAN Volume Controller (SVC) and Storwize Family delivers an additional option with a 900 GB 15K rpm 2.5-inch SAS drive.
(Honestly, I didn't think we would see larger capacity 15K drives, but IBM was qualifying these for the DS8000 boxes, and made sense to add them to the Spectrum Virtualize hardware offerings as well.)
This week, I was in beautiful Melbourne, Australia for IBM Systems Technical University.
PowerAI overview and Cognitive Solutions on POWER
Anand Subramaniam, IBM Technical Specialist, presented this session on PowerAI. IBM packaged a collection of Machine Learning libraries, optimized them for POWER8 chip-set, and made this entire package freely available for download as "PowerAI".
IBM also is working on a priced value-add collection called "PowerAI Vision"
Hadoop Infrastructure solutions and Point-of-View
Alexis Giral, IBM Executive Storage Architect, presented the benefits of IBM Spectrum Scale using a simple example. Supposed you are gathering 40TB of sensor readings per day. How many TB of storage would you need to hold 2 years worth of data?
Traditionally, HDFS maintains three copies of the data. A recently added feature "HDFS-EC" provides erasure coding to reduce the overall storage requirements. Giral showed this chart:
5+4 Erasure Coding
Spectrum Scale ESS
8+3 Erasure Coding
And this is assuming all the data is hot. If you decide to keep only 30 percent hot, perhaps the most recent eight months, and the other 70 percent on colder storage, you may reduce your storage requirement costs even further.
IBM Cloud Object Storage - Redefining backup infrastructure
Maciej "Mac" Lasota, presented the use of IBM Cloud Object Storage as a backup repository. While IBM Spectrum Protect is the preferred choice, IBM COS also works well with Commvault and NetBackup.
He listed some of the challenges that companies have with backups to tape, and how IBM COS addresses these challenges.
(While IBM COS is three to four times more expensive than tape, it is a luxury many clients can now afford!)
He wrapped up the session showing five different deployments that he worked on for clients.
New Generation of Storage Tiering: Simpler Management, Lower Costs, and Improved Performance
With ever changing amounts of storage, it is hard to find metrics that are consistent year to year. Fortunately, we found I/O density as the metric to focus my efforts, armed with real data from Intelligent Information Lifecycle Management (IILM) studies done at various clients. From that, I was able to talk about storage tiering on three fronts:
IBM Easy Tier on DS8000 and Spectrum Virtualize to provide tiering within a system.
IBM Virtual Storage Center (VSC) to provide tiering between systems in a data center.
IBM Spectrum Scale, Spectrum Archive and IBM Cloud Object Storage System to provide global tiering across multiple locations, and across flash, disk, tape and cloud resources.
Spectrum Scale for Volume, File and Object Storage
IBM Spectrum Scale was formerly called GPFS and has been around since 1998. I am glad it was renamed, as GPFS suffered from "guilt by association" with other file systems, AFS, DFS, XFS, ZFS, and so on.
Spectrum Scale does so much more, supports volume, file and object level access, supports POSIX standards for Windows, AIX and Linux, support Hadoop and Spark with 100 percent compatible HDFS Transparency Connector, support NFS, SMB and iSCSI protocols, as well as OpenStack Swift and Amazon S3 object based access.
Initially designed for video streaming and High Performance Computing (HPC), IBM has extended its reach to work in a variety of workloads across different industries. More than 5,000 production systems are running at client locations.
Beating Ransomware! A deep exploration of threat vectors for applications and storage
Andrew Greenfield, IBM Global Engineer for Spectrum Storage, presented on the threat of ransomware. In addition to being an expert in various storage, he also is an expert in security.
If you think security is just setting up your network firewalls and turning on data-at-rest encryption on your storage, you are sadly mistaken. Many of the treat vectors come from the inside, disgruntled employees or temporary contractors who plant viruses, bombs and worms that may not activate until long after they leave.
There are now products called security information and event management (SIEM) that provide real-time analysis of security alerts generated by network hardware and applications. Two that Andrew was familiar with were IBM Qradar and Varonis. These identify standard and abnormal behavior patterns among users.
Andrew feels products like Splunk do a great job to collect information, but don't do the analysis that Qradar or Varonis do.
I was very pleased with this conference. This was a concentrated 3-day event, but everyone I talked to was happy with the format, and felt their time spent worthwhile!
This week, I was in beautiful Melbourne, Australia for IBM Systems Technical University. On Wednesday evening, we had a poster session.
(I have so many photos that I will split this post up into topics. This post will focus on IBM Z systems, see my other posts for storage and IBM Power systems.)
Topics can be anything that is of interest to your peers and colleagues. It can be research-related, a specific solution you implemented or an interesting customer case you want to share.
Linux Scalability at a Small Scale (or, An Adventure In Minimalist Multitudinousness)
Vic Cross, IBM Senior Systems Engineer, used the Ganglia Monitor System to generate traffic and measure 1,680 Linux guests on a single IBM Z mainframe LPAR with only 16GB of memory! His poster consisted of 18 pages of material, a mix of traditional presentation slides, screen shots of web pages, and densely detailed performance results.
Ganglia is a scalable distributed monitoring system for high-performance computing systems such as clusters and Grids. It is based on a hierarchical design targeted at federations of clusters. It leverages widely used technologies such as XML for data representation, XDR for compact, portable data transport, and RRDtool for data storage and visualization. It uses carefully engineered data structures and algorithms to achieve very low per-node overheads and high concurrency. The implementation is robust, has been ported to an extensive set of operating systems and processor architectures, and is currently in use on thousands of clusters around the world. It has been used to link clusters across university campuses and around the world and can scale to handle clusters with 2000 nodes. Learn more at [http://ganglia.sourceforge.net/]
Spectrum Scale 2 site cluster
Antony Steel, IBM Senior Consulting IT Specialist, presents an option to configure a 2 site GPFS (Spectrum Scale) "almost active-active" cluster when a 3rd site is not available. This option will require simple administrative tasks to make DR filesystem available should Production site fail. Spectrum Scale runs on IBM Z, IBM Power and x86 servers.
The poster used 13 traditional landscape slides, printed on what appears to be A4 paper. A4 is 297 mm wide, so three side by side exceeds the 841 mm width of the poster foam board. These were arranged with a title slide on top, and then 12 content slides in four rows of three.
While I was glad that someone else had a QR code on their poster, the placement was way at the top, and difficult for anyone to actually scan it. I thought of this, and had mine at waist level in the middle right side of my poster.
Life is better with Linux
I couldn't resist taking a photo of the back of this guy's tee-shirt, which says "Life is better with Linux"
In effect, tee-shirts can also be "posters", although that would make for an awkward "poster session" if everyone wore them? Pointing at your chest would be weird, and pointing to your back would be near impossible!
In 1999-2001, I helped the port of Linux to IBM S/390 mainframe chip-set architecture by testing and debugging the disk and tape device drivers. I was the first to install Linux on an IBM mainframe in Tucson, AZ!
I would then go on to work with SAN Volume Controller, Tivoli Storage Manager (now called Spectrum Protect), Tivoli Storage Productivity Center (now called Spectrum Control), and the General Parallel File System (GPFS, now called Spectrum Scale). All of these run on Linux!
I would become the "Linux storage expert" at conferences like SHARE and GUIDE. While my co-workers in DFSMS and z/OS felt Linux was just a fad, I predicted that Linux was going to be a major force in the IT industry. I was right, not only does Linux run on all of our IBM Z and Power servers, it is the underlying operating system for nearly all of IBM storage devices.
Today, I run Linux directly on my laptop, using a Windows KVM guest image as needed for specific projects or applications.
Erina Araki poses for a photo with one of the attendees, Marco. Erina was the organizer for this poster event, and was my primary contact to answer all of my questions. I think the poster session was a big success!
This week, I was in beautiful Melbourne, Australia for IBM Systems Technical University. On Wednesday evening, we had a poster session.
(I have so many photos that I will split this post up into topics. This post will focus on posters related to IBM Power systems. See my other posts for storage and IBM Z.)
Ding! IBM i Systems Management redefined with SQL
A poster presentation should trigger question-and-answer sessions, and the exchange of ideas and information regarding your topic.
Scott Forstie, IBM Db2 for i Business Architect, coined the phrase "Scott's Query Language", focused on Data Services for Db2 database on IBM i operating system. His design took several charts, printed in landscape mode, and organized in 3 columns of four charts each. His "title" page was printed twice, and placed on the left and right sides.
Scott explained GROUP_PTF_CURRENCY, LICENSE_EXPIRATION_CHECK and ACTIVE_JOB_INFO. I am not familiar with any of these things, but I enjoyed how passionate Scott was. He even had business cards for people to get more information at: [ibm.biz/Db2foriServices]
IBM Spectrum Scale with Hortonworks Data Platform
Chris Maestas, IBM Global Senior Solutions Architect, IBM and Par Hettinga, IBM Global SDI Enablement Leader, created this poster.
Hortonworks is a leading innovator in the industry, creating, distributing and supporting enterprise-ready open data platforms and modern data applications. They focus on driving innovation in open source communities such as Apache Hadoop, NiFi, and Spark. Their product, Hortonworks Data Platform (HDP), runs on both x86 and Power systems.
The poster design was clean, with basically three enlarged presentation slides. On the top, it explains that Hortonworks now supports IBM Spectrum Scale for storage of files and objects to be analyzed by Hadoop. On the bottom left, it shows how Spectrum Scale eliminates the ingest-and-discard approach used by other HDFS-based systems. On the bottom right, an architecture diagram to build your own "data lake".
Optimizing Power Performance with Affinity Groups – Real World 40Gbit LPM Results / Lessons Learnt
This poster employed a unique 1-6-6 design. Top slide was for title and author: Stephen Diwell, Senior Power Systems Engineer, DXC Technologies
In the middle, the poster had six traditional text-only presentation slides, arranged in two rows of three. LPAR Affinity Groups provides you the ability to give the Hypervisor a hint that you would like this group of LPARs to be located on processor Chips that are closer to each other. Use Affinity Groups to help the Hypervisor place LPARs nearer to the VIO Servers. LPARs that share common resources, like the Fibre Channel and Ethernet adapters within a VIO servers will obtain better performance and adapter throughput the closer they are. The lighting on some of these posters was really poor, and perhaps too dark to read small fonts like this.
At the bottom were performance bar chart results, in three rows of two. I like the use of color for the graphs. For a network job with 8 threads, Stephen achieved a 54% increase in network bandwidth for LPARs communicating on the same Chip to those communicating between Nodes in the E800 frame.
Sundata Power Server Cloud offering
Leave it to the marketing department of a local cloud service provider to turn their poster into an advertising billboard! This one was presented by Kon Kakanis, Managing Director, Sundata Pty Ltd
The Sundata poster encouraged people to move their AIX, IBM i and Linux on POWER workloads to their "PowerCloud" platform. They summarized their advantages into four bullet points:
Reliable and cost-effective partnership
Advice, Guidance and Support
Migration, management and support services
Located in Sydney and Brisbane
Founded in 1986, Sundata is an Australia-based organization to help their clients transform into the Cloud, select and deploy IT hardware and keep the lights on with ongoing support and managed services. They have over 100 corporations, government departments and schools enjoying a close and ongoing relationship.
The large fonts, simple design, and the cute cat-in-a-cape logo in the lower right corner captured peoples attention!
In between reading posters and talking to everyone, it was good to take a quick look out the floor-to-ceiling windows. At 297 meters, Eureka Tower has some amazing views. Here is one of the Yarra river and Central Business District.
This week, I was in beautiful Melbourne, Australia for IBM Systems Technical University. On Wednesday evening, we had a poster session. This was the first time I presented a poster session, so I was understandably very excited.
(I have so many photos that I will split this post up into topics. This post will focus on storage posters. See my other posts for IBM Power and Z systems.)
The venue was Eureka Skydeck 89, the top floor of the Eureka Tower. This tower is 297 meters tall (974 feet), and the views it afforded of the city of Melbourne were stunning.
Mo and I arrived early as I was one of the 11 finalists that got selected to present a poster. While it is a hot summer back in Arizona, it is cold here in Australia. I am glad we brought our heavy coats for the brisk 8-minute walk from our hotel, the Crown Promenade, to the Eureka Tower.
Posters are designed to present specific topics in a concise and interactive way to appeal to peers and colleagues at conferences and/or public displays. Everyone would be given an "A0" poster size foam board on which to tape on their poster, 841mm wide, and 1189 mm tall (roughly three feet by four feet).
Understanding Converged and Hyperconverged Systems
My design was simple. I took my summary chart from one of my presentations, and enlarged it to fit the "A0" poster size. I chose my "Pendulum Swings" presentation that explains the history of storage infrastructure, and the rise in interest in Converged and Hyperconverged Infrastructure.
In the early days of IT, storage was internal to its server, over time, storage outgrew its container, and we started having externally attached storage, and benefits like RAID and clustered servers for high availability. Then, SANs, LANs and WANs took the main stage, allowing for greater connectivity and distance.
But now, it seems the pendulum is swinging back with converged and hyperconverged systems. Converged Systems like IBM PureSystems, or VersaStack from IBM and Cisco, provide best-of-breed hardware for servers, storage and networks in a pre-cabled, pre-configured rack. With everything in a single rack, port count and cable distance limits are no longer a major concern.
Hyperconverged Systems, such as IBM Spectrum Scale, IBM Spectrum Accelerate, Nutanix or Simplivity, focus instead on offering commodity servers with internal flash and disk storage. Software-Defined Storage software is then used to glue together multiple units over a LAN infrastruture. With the huge increase in Flash and Disk capacities, a server with internal storage can hold many TB of data.
My poster included a "QR Code" that pointed to a link on BOX so that people could use their smartphones to access all of my presentations.
IBM Spectrum Scale with focus on Active File Management
A poster presents not all the details but the most important information.
Trishali Nayar, IBM AFM/Spectrum Scale Development from Pune India, had a poster on IBM Spectrum Scale with focus on Active File Management (AFM). She had a clean, simple design, basically two presentation slides enlarged to fill the poster size.
Active File Management (AFM) enables sharing of data across clusters, even if the networks are unreliable or have high latency. AFM allows you to create associations between IBM Spectrum Scale™ clusters or between IBM Spectrum Scale clusters and NFS data source. With AFM, you can implement a single name space view across sites around the world making your global name space truly global. You can also duplicate data for disaster recovery purposes without suffering from WAN latencies.
IBM Ubiquity Storage Service for Container Ecosystems
Your audience isn't trying to replicate your solution or case -- they are simply after the basics. Take for example, this poster on IBM's Ubiquity Storage Services.
Ashutosh Mate, IBM WW Senior Solutions Architect, created this poster on storage for Containers. Not to be confused with the Containers used in Spectrum Protect container pools, or the Containers supported by IBM Cloud Object Storage!
The poster had six enlarged presentation slides. Two at the top under "Abstract" covered business need and technology overview. The two in the middle under "Ubiquity Architecture" had a connection diagram and a list of supported environments. The last two under "IBM Vision" covered customer value, use cases, and additional resources.
As people transition from monolithic applications to microservices, IT is shifting from heavy Virtual Machines to lightweight Docker containers.
The Ubiquity project enables persistent storage for the Kubernetes and Docker container frameworks. It is a pluggable framework available for different storage systems. The framework interfaces with the storage systems, using their plugins. Different container frameworks can use Ubiquity concurrently, allowing access to different storage systems.
IBM has support for Spectrum Scale, all of the Spectrum Accelerate offerings (including XIV, FlashSystem A9000/R) and all of the Spectrum Virtualize offerings (including SVC, Storwize and FlashSystem V9000).
Single page handouts as "take-aways" was a nice extra touch.
This week, I was in beautiful Melbourne, Australia for IBM Systems Technical University. Here is my recap of Day 2.
The Truth Behind Converged/Hyperconverged Solutions
Abilio De Oliveira, IBM Client Technical Specialist, presented his thoughts on Converged and Hyperconverged solutions.
I went to hear what Abilio had to say, as I was presenting a similar session later the same day. There is a lot of hype surrounding both Converged and Hyperconverged systems, and Abilio was not buying it. He cautioned that there were over 25 vendors in this space, and often what they claim does not match reality.
He ended with a hilarious comparison, using the Television shows "Finding Bigfoot" and "Monster Hunters" as analogies.
Cloud storage comes in four flavors: persistent, ephemeral, hosted, and reference. The first two I refer to as "Storage for the Computer Cloud" and the latter two I refer to as "Storage as the Storage Cloud".
I also explained the differences between block, file and object access, and why different Cloud storage types use different access methods.
Finally, I covered some of our new public cloud storage offerings, using OpenStack Swift and Amazon S3 protocols to access objects off premises, including the new Cold Vault and Flex pricing on IBM Cloud Object Storage System in IBM Bluemix Cloud.
A guide to assist you to build a business continuity solution
Alexis Giral, IBM Executive Storage Architect, presented business continuity and the various technologies IBM has to offer for disaster recovery.
I went to hear what Alexis had to say, as I was presenting a similar session later the same day. The first part of his presentation was nearly identical overview of basic concepts, such as recovery point objective (RPO) and recovery time objective (RTO), but the rest of his talk focused on the technologies in the storage products to use for each Business Continuity tier.
Pendulum Swings Back -- Understanding Converged and Hyperconverged Systems
For Converged Infrastructure, IBM and Cisco have greatly expanded the offerings in VersaStack. IBM supports SVC, Storwize V7000, Storwize V5000, FlashSystem 900, FlashSystem V9000 and FlashSystem A9000. The Cisco UCS x86 servers can be configured for IBM Cloud Object Storage System. VersaStack also supports Cisco CloudCenter to provide Hybrid solution taking advantage of IBM Spectrum Copy Data Management.
For Hyperconverged Infrastructure, IBM offers both Spectrum Accelerate and Spectrum Scale software. Recently, IBM has partnered with Nutanix to provide pre-installed POWER8 servers that run a customized version of their Acropolis Hypervisor. This supports Little-Endian Linux distributions from Centos and Ubuntu to run as Virtual Machines.
Business Continuity - The seven tiers of Disaster Recovery
Back in 1983, a task force of IBM clients at a GUIDE conference developed "Seven Business Continuity Tiers for Disaster Recovery", which I refer to as "BC Tiers". I divided the presentation into three sections:
Backup and Restore: BC tiers 1 through 3 are based on backup and restore methodologies. I explained how to backup Hadoop analytics data, all of the various options for IBM Spectrum Protect software, and how to encrypt the tape data that gets sent off premises.
Rapid Data Recovery: BC tiers 4 and 5 reduce the Recovery Point Objective (RPO) and Recovery Time Objective (RTO) with snapshots, database journal shadowing, and IBM Cloud Object Storage.
Continuous Operations BC tiers 6 and 7 provide data replication mirroring across locations. I covered 2-site, 3-site and 4-site configurations. I added details on IBM GDR for Power Systems which supports AIX, IBM i and Linux on POWER disaster recovery with DS8000 and Spectrum Virtualize storage.
While I was working, Mo took a city tour. Here she is taking a picture on the river walk along Melbourne's Yarra River.
Melbourne is a very clean city, people are friendly, and the architecture of the various buildings in the "Central Business District", or CBD as the locals call it, is stunning. Every building is unique!
Tonight we have a special "poster session" on the top floor of Melbourne's tallest building that is said to have excellent views of the city.
My session on IBM Cloud Object Storage had three sections. First, I covered an overview of what "Object Storage" was in general, how this differs from traditional block or file storage approaches.
Second, I explained what is unique and different of IBM Cloud Object Storage System, formerly called DsNet from Cleversafe. IBM acquired Cleversafe in 2015.
Third, I explained the various applications, use cases and industries that can take advantage of Object Storage.
IBM Storage and the NVMe Revolution
Brian Sherman, IBM Distinguished Engineer for Storage Advanced Technical Services, presented an overview of NVMe, NVMe Over Fabric (NVMeOF) and what IBM is doing in this area.
How to Build a Rockstar Personal Brand
Andrea Edwards, The Digital Conversationalist, is a globally award winning B2B communications professional with more than 20 years' worth of experience from around the globe, including 12 years exclusively in Asia Pacific. IBM has hired her in the Asia Pacific region to train many IBMers in Social Media.
She condensed her normal 5-6 hour training down to a single hour for this event. She explained why building a personal brand was important, how to do it, and why businesses and organizations should encourage their employees to do so.
For example, who has the most influence on most people? Behind friends and family are bloggers. Bloggers are more influential than journalists, religious leaders, celebrities and politicians.
(As the #1 blogger of IBM, I am considered to already have a "rockstar personal brand". I am pleased to see that IBM is taking social media seriously. I have been blogging since 2006, and have influenced over $4 billion US dollars in IBM revenue in the past 11 years.)
IBM Spectrum Virtualize technical updates
Andrew Martin, IBM Spectrum Virtualize Support Architect, presented the last 18 months of enhancements to Spectrum Virtualize, from v7.6.1 introduced in March 2016 to v7.8.1 released earlier this year.
He managed to highlight quite a few enhnacements:
Distributed RAID 5 and RAID 6
Integrated Compresstimator tool
New hardware: SVC, Storwize V7000 Gen2+, Storwize V5000 Gen 2, and 92-drive 5U High Density Expansion Enclosure
N-Port ID Virtualization (NPIV)
Virtualization Over iSCSI
Encryption for Distributed RAID Arrays
64GB Read Cache
Tier 1 Flash Support
Compressed IP Replication
Spectrum Virtualize as Software for Lenovo and SuperMicro servers
Host Clusters and Throttling
Raised limit to 10,000 Volumes
Transparent Cloud Tiering
Storwize Model Conversions
IBM SKLM Support for Encryption
Consistency Protection for Metro and Global Mirror remote-distance replication
Andrew called this a "reverse roadmap", rather than a session that presents where we are going in the next 18 months, he presented where we have been.
Solution Center Reception
Here I am with Morgan Tracey and Jenna Brooker from Computer Merchants, an IBM Business Partner.
Not only were Computer Merchants a sponsor with a booth at the Solution Center, but they also gave a customer testimonial at one of the breakout sessions on how they were able to use IBM Artificial Intelligence to help with their business.
I also spent time at the SuSE booth. SuSE is a distributor of Linux that runs on x86, POWER and IBM Z mainframe systems.
While I was working, Mo took a tour to Phillip Island. On the way, they stopped at Maru to feed kangaroos and take pictures with Koala bears.
At Phillip Island, Mo watched penguins come out of the ocean, waddle up on shore and march to their burroughs. This happens every evening and is one of the top tourist attractions near Melbourne.
Last week, I was in São Paulo, Brazil for IBM Systems Technical University.
Did the resort ask these two security guards to dress up as clowns? No, it turns out these were clowns dressed up as security guards! On other days, they were dressed in drag as housewives, or as Jamaican Rastafari in dreadlocks and tie-dyed tee shirts. Some of the attendees enjoyed their comic relief.
Here is my recap of Day 3 breakout sessions:
Demystifying Transparent Cloud Tiering for DS8000 and DFSMShsm
Ricardo Alan, IBM Client Technical Specialist, covered this recently announced synergy between DS8000 firmware and DFSMShsm, a part of the z/OS operating system for IBM Z mainframes.
(Historical note: I started my career as a software engineer for DFHSM, which was later renamed DFSMShsm, working my way up to lead architect for DFSMShsm, and later as chief architect for DFSMS overall. A good portion of my 19 patents are related to these products.)
Since the 1970s, mainframe clients were able to move less active data from expensive disk storage to lower cost tape media. DFSMShsm would be read data sets into the mainframe processor, chop them up into 16KB blocks, and then write them out to tape, often through an automated tape library.
Transparent Cloud Tiering introduces an alternative option. DFSMShsm now identifies which tracks of data need to be re-located, sends the request to IBM DS8000 storage device, and the IBM DS8000 sends the tracks as objects to the Cloud. Any application that references these data sets would automatically trigger a recall to bring the data back from the Cloud.
This feature is available for the DS8870 and DS8880 models, using the existing Ethernet ports already installed. No additional hardware is required. Enhancements to DFSMShsm will be rolled out via SPEs on z/OS releases. Initially, the system uses OpenStack Swift object protocol, but IBM has plans to support Amazon S3 protocol as well.
Data Migration Challenges and Solutions with IBM Enterprise Storage
Sidney Varoni Jr. presented this session on data migration methods. Data is migrated for three reasons. First, to re-balance across multiple storage arrays. If you bring in a new storage array, you often want to move data from older arrays to balance the workload.
The second reason is to get rid of old hardware altogether, you need to migrate the data to new hardware. With Dell acquisition of EMC, for example, many clients are using tools like TDMF to move data off of EMC and onto IBM DS8000 storage systems. IBM DS8000 storage systems are faster, easier to use and less expensive to operate from a total cost of ownership (TCO) than comparable capacity of EMC VMAX devices.
The third reason is to migrate from one data center to another. The average data center was built 10-15 years ago, and many no longer meet the needs and requirements of newer IT operations. Some clients are building new data centers, while others are moving their data to co-location facilities.
NVMe Over Fabrics: The next evolution in high performance for SSD interfaces is NVMe
Waner Dall Averde, Territory Representative from Brocade, presented this session on NVMe and NVMe Over Fabric (NVMeOF). As a joke, he showed this chart in Japanese.
(Fun Fact: The first Japanese immigrants arrived in Brazil in 1908. Brazil is home to the largest Japanese population outside Japan. Source: Wikipedia)
For the past 20 years, the Advanced Host Controller Interface (AHCI) served as the communication mechanism to send SCSI commands to SAS and SATA disk devices.
Unfortunately, AHCI is now the bottleneck between faster servers and faster Non-Volatile Memory such as Flash and Solid State Drive (SSD) storage devices. It only supports a handful of commands on a single command queue.
NVMe offers a replacement for the SCSI command set. It can support up to 64,000 commands on as many as 64,000 parallel command queues. Designed for 32 Gbps PCIe bus speeds, it is faster than traditional 6 Gbps and 12 Gbps SAS connections, reducing latency by 200 microseconds.
Unfortunately, PCIe cables are limited to just a few inches. PCIe Gen 1 supported 15 inches, PCIe Gen 2 supported 12 inches, and PCIe Gen 3 only 8 inches. To provide greater distances, NVMeOF allows the NVMe command set to be carried over long-distance networks, such as Ethernet, Infiniband or Fibre Channel.
Brocade Gen5 (16 Gbps) and Gen6 (32 and 128 Gbps) Fibre Channel switches and directors already support NVMeOF, and are designed to allow co-existence between NVMe and SCSI commands for smooth transition in mixed environments. Clients can buy their networking gear directly from IBM.
IBM Power Systems Flash Cache Acceleration
Petra Bührer, IBM Offering Manager for Power Systems software, explained recent the performance enhancement called "Flash Cache Acceleration".
This is a feature on POWER8 servers running AIX 7.1 TL4 SP2, AIX 7.2 TL0 SP0 – or higher. By using internal or direct-attach SSD, the operating system can cache most active blocks of data from external storage systems.
While this is certified for use with Oracle, it supports only single-instance databases. Oracle RAC and other active/active configurations are not supported at this time.
The Secret to IBM Disk Encryption - Deep Dive
As if Mo McCullough, one of the event coordinators for this conference, was not busy enough with keeping the conference going, he also gave technical presentations.
With the excitement over the IBM z14 end-to-end encryption announcement, there has been increased demand for everything related to encryption and security.
Unfortunately, I had to leave for the airport before the "Closing Session". The Club Med Lake Paradise resort was 60-90 minutes away from the GRU airport, and rush hour traffic in a city of 12 million people can get really bad.
Last week, I was in São Paulo, Brazil for IBM Systems Technical University.
Instead of separate physical rooms for each breakout session, this event had "virtual rooms". One speaker called it the "Software Defined Stage". Basically, there were five "rooms" in the main ballroom, and another eight rooms in a second ballroom.
Rather than blasting out each speaker's voice over loudspeakers, each speaker spoke softly into a headset microphone. All attendees wore headsets. Rooms 1 through 4 offered real-time translation, so attendees could chose to hear in English or Brazilian Portuguese.
In the other 13 "rooms", local speakers spoke in Brazilian Portuguese, but you still had to wear headsets to avoid speaking louder than the speaker next to you. For many of these, the charts were written in English.
My translators, Luciana and Marilia, explained to me the advantage of this approach. When speakers use English language, those who prefer must hear the real-time translation wore the "headphone of shame" which advertised to all others that an attendee's English proficiency was poor.
Sometimes, those who did not understand English well would not wear their headsets, nod or laugh with other attendees, but fail to understand the message. By forcing everyone to wear headsets, there is no stigma associated, and everyone can discreetly select the language they prefer to listen in.
Here is my recap for the breakout sessions on Day 2:
In this presentation, I gave an overview of interest in Cloud technologies, including OpenStack and RESTful APIs to manage server and storage resources. I then covered IBM Hybrid Cloud Storage configurations in five categories:
Cold storage for data infrequently accessed
Backup and Snapshot storage
Disaster Recovery storage
Daily Operations and Reporting
Special thanks to Chris Vollmar and Brian Sherman for their help in preparing this presentation.
Data Optimization: How to verify your data is being used efficiently
It is hard to believe that it was over 15 years ago that I was the chief architect for the software we now call IBM Spectrum Control. There are a variety of editions and bundles for this product, but my focus on this talk was on the advanced storage analytics found in IBM Virtual Storage Center and IBM Spectrum Control Advanced Edition.
I covered three use cases:
What storage tier to put your workload in, and how to move existing data into a faster or slower tier to meet business requirements and IT budgets.
For steady state environments, how to re-balance storage pools within a single tier to keep things even for optimal performance.
When it is time to decommission storage, how to transform volumes from one storage pool to another without downtime or outages.
Special thanks to Bryan Odom for his help in preparing this presentation.
IBM Hyperconverged Systems powered by Nutanix: Technical Overview
Ricardo Matinata, IBM Senior Technical Staff Member for Linux, KVM and Cloud on POWER, presented the latest IBM CS models for POWER systems that are pre-installed with Nutanix software running their Acropolis Hypervisor (AHV) to run Linux on POWER application virtual machines.
Managing Risks with Thin Provisioning, Compression, and Data Deduplication
This session had four parts. First, an overview of "Data Footprint Reduction" technologies, like compression, data deduplication, space-efficient snapshots and thin provisioning.
Second, a look at how these technologies can get storage administrators in trouble. Much like airlines selling more tickets than seats on the airplane, storage administrators may over-provision based on data reduction estimates, and then suddenly run out of storage capacity.
Third, an overview of IBM FlashSystem A9000 and A9000R products, often referred to as "A9000/R" to cover both as a family. These models offer data footprint reduction for all data.
Finally, I explain how the Hyper-Scale Manager GUI can help with reporting and analytics to avoid these risks. This GUI is available for the FlashSystem A9000/R, as well as XIV Gen3 and Spectrum Accelerate software clusters.
Special thanks to Rivka Matosevich for her help in preparing this presentation.
The Right Flash for the Right Workload
Fabiano Gomes, IBM Client Technical Specialist, presented IBM's portfolio of All-Flash Arrays, from FlashSystem and DS8000F to Elastic Storage Server and Storwize V7000F and V5000F models. Each of these have their own characteristics, which might favor one over the others for particular workloads and use cases.
The day was capped off with a nice evening reception at the pool bar. Bartenders were serving Caiparinhas, a Brazilian cocktail traditionally made sugar cane liquor, sugar and lime, but in this case offered in other flavors, such as pineapple or passion fruit.
Last week, I was in São Paulo, Brazil for IBM Systems Technical University.
Luciana and Marilia
While I speak Spanish fluently, my Brazilian Portuguese is a bit rusty, so I was asked to present in English language, and let these two real-time translators, Luciana and Marilia, speak on my behalf.
A big challenge is that English is a terse language, but Brazilian Portuguese is more verbose. It takes more syllables, and thus more time, to perform real-time translation. I have learned to pause at the end of each sentence to give a chance for my translators to catch up.
Servers (2 syllables)
Servidores (4 syllables)
Storage (2 syllables)
Armazenamento (6 syllables)
In this table, you can see that some technical terms take more syllables in Brazilian Portuguese than English. Often, I heard the local speakers just say "Servers" or "Storage" for convenience.
Here is my recap of breakout sessions on Day 1.
IBM Storage Trends and Directions
Alcides Bertazi, IBM Executive IT Specialist, presented the latest in Storage Trends and Directions.
Introduction to Object Storage and its Applications
This session had three sections. First, I covered an overview of what "Object Storage" was in general, how this differs from traditional block or file storage approaches.
Second, I explained what is unique and different of IBM Cloud Object Storage System, formerly called DsNet from Cleversafe. IBM acquired Cleversafe in 2015.
Third, I explained the various applications, use cases and industries that can take advantage of Object Storage.
IBM Spectrum Copy Data Management for Beginners
Eduardo Tomaz, IBM Client Technical Sales for Software Defined Storage solutions, presented an overview of IBM Spectrum Copy Data Management (CDM), the newest member of the IBM Spectrum Storage family.
IBM Spectrum Protect Update
Rosane Lagnor, IBM Certified IT Specialist - Storage Consultant Lab Services, and her two colleagues co-presented this session on the latest of IBM Spectrum Protect. The review went chronologically, from v7.1.4 introduced in late 2015, all the way to v8.1.1 release, the latest generally available.
(Note: IBM just announced v8.1.2 but is not generally available yet in Brazil.)
I managed to understand the local speakers in their native Brazilian Portuguese language. In many cases, the charts were in English language, so I was able to read in English what I may not have understood was spoken.
Last week, I was in São Paulo, Brazil for IBM Systems Technical University. With over 12 million people, it is the most-populous city in the Americas. Our venue was the Club Med Lake Paradise resort on the outskirts of town. We had about 700 attendees.
We had several local speakers do the opening session. Here is my recap:
Marcelo Porto, IBM General Manager for Brazil
This year, IBM Brazil celebrates 100 year anniversary. This all happened because Valentim Boucas persuaded IBM then-President Thomas Watson, Sr. to approve the establishment of a Rio de Janeiro office for the sale of IBM machines beginning in 1917.
For 100 years now, IBM has thrived with a set of core values. In every era in the past, IBM systems have been perfect for the business needs at the time, from punch cards to personal computers. But what got us here won't get us there in the future. The biggest challenge to transformation is people and culture. We must break the chains that hold us to the past. IBM drives disruption.
To prepare for the future, Marcelo recommended the following. First, learn English, because the English language is the "API of Business". Second, keep a curious mind. Seek out new things to learn. The new world needs skills and expertise in a variety of areas. Third, watch the movie "Hidden Figures", starring the IBM mainframe computer.
IBM Watson computer now speaks and understands Brazilian Portuguese language. Groupo Fleury uses Watson for genomics research. MRV Engineering uses this for chatbots. Mae de deus Hospital uses this for Oncology, as cancer patients now dominate the percentage of patients there. Walmart uses Blockchain to focus on food safety.
IBM Watson is used at Pinacoteca de São Paulo Museum to offer "Voz de Arte", the ability to ask IBM Watson about each painting in handheld smartphone devices. An example of this was available in the Solution Center.
In addition to natural language processing (NLP), IBM Watson can also do image recognition, a task normally only humans could do.
Watson can validate signatures, perform facial recognition at different angles, and even identify shirts, pants and shoes of fashion models in photographs.
Companies and organizations that are unable to transform data into insights and business decisions will fail.
Mauro D'Angelo, IBM Strategy and Business Development for Brazil
Why are companies like Uber and Airbnb successful? Mauro felt that it was because they had a proper Cloud infrastructure combined with the right data architecture.
(In this case, "success" is based on company valuation, often billions of US dollars. However, many of these companies are not profitable, losing millions of dollars in an aggressive effort to gain customers and establish their platform. It might take 12 to 24 months before a new customer becomes profitable.)
The data explosion is driving digital transformation. Cognitive systems must understand natural language, reason, learn and interact with humans. Machine Learning is much like training a puppy. You need to reward good behavior and fix bad behavior, and be patient, as it takes a long time.
In USA, patients asking Doctors for a diagnosis get only 50 percent correct on first consultation. Often, additional doctors or additional tests are needed to finally get correct assessments. In Brazil, it is probably less than 50 percent. Hopefully, Watson will help improve this.
Watson can also detect emotional tone and personality in social media. Is a customer angry? This could help prioritize which customer issues to address first.
Schools have not changed since the days of Aristotle. Mauro showed a picture of a school taken in 1934, and a picture of the same classroom, taken recently, showing it is nearly the same. Students want to learn anytime, anywhere, and from any channel.
At Georgia Tech University, a professor told his engineering students that there were nine "Teacher Assistants" (TAs) available to help answer questions online. One of these was [Jill Watson], which was the IBM Watson computer responding to the students. The students could not tell that Jill was not human!
In traditional schools, a teacher may reach only 50 to 60 students. Compare this to [Khan Academy] that offers video instruction that have had over 1.3 million views!
Frank Koja, IBM Systems Vice President for Brazil
When you buy something over the internet, what is your decision criteria? Often, it is lowest cost. Digital transformation often requires re-invention.
Trust beats risk. The new IBM z14 mainframe focuses on trust, with end-to-end encryption, Blockchain and Machine Learning. zHyperLink drastically improves the connection between mainframe and IBM DS8880 storage. IBM is helping over 400 clients adopting Blockchain.
The FlashSystem A9000 and A9000R models are 30x faster than traditional disk systems, and more dense, able to consolidate 20 racks down to one.
The new "PowerAI" bundle combines together a complete offering for Machine Learning and Deep Learning (ML/DL) for Power systems, taking advantage of GPU and NVlink capabilities.
The "waitless" world has arrived.
This was a good start for the conference. The three speakers of the opening session were passionate of what they were talking about, and people were excited to learn more as the week progressed.
The article starts out giving background history of the current mess we are in. Here is an excerpt:
"Throughout most of U.S. history, American high school students were routinely taught vocational and job-ready skills along with the three Rs: reading, writing and arithmetic...
...But in the 1950s, a different philosophy emerged: the theory that students should follow separate educational tracks according to ability...
Ability tracking did not sit well with educators or parents, who believed students were assigned to tracks not by aptitude, but by socio-economic status and race. ...
...The backlash against tracking, however, did not bring vocational education back to the academic core. Instead, the focus shifted to preparing all students for college, and college prep is still the center of the U.S. high school curriculum..."
My father was a mechanical engineer who enjoyed fixing cars and woodworking on the weekends. I had plenty of "vocational training" growing up at home, no need for me to have this in school, allowing me to focus on getting ready for college.
Nicholas asks legitimate questions at this stage: "So what’s the harm in prepping kids for college? Won’t all students benefit from a high-level, four-year academic degree program?" His initial response is:
"... As it turns out, not really. For one thing, people have a huge and diverse range of different skills and learning styles. Not everyone is good at math, biology, history and other traditional subjects that characterize college-level work.
Not everyone is fascinated by Greek mythology, or enamored with Victorian literature, or enraptured by classical music. Some students are mechanical; others are artistic. Some focus best in a lecture hall or classroom; still others learn best by doing, and would thrive in the studio, workshop or shop floor..."
Hard to argue that people are different, and learn in different ways. Not everyone is meant for college.
"...And not everyone goes to college. The latest figures from the U.S. Bureau of Labor Statistics (BLS) show that about 68 percent of high school students attend college. That means over 30 percent graduate with neither academic nor job skills..."
Here is what I have most problems with. To think that the 30 percent of high schools students graduate, but do not go to college, have neither academic nor job skills? I disagree with this, as there are many jobs where the academic and job skill training they received in high school is more than adequate. Nicholas then doubled down:
"...But even the 68 percent aren't doing so well. Almost 40 percent of students who begin four-year college programs don’t complete them, which translates into a whole lot of wasted time, wasted money, and burdensome student loan debt. Of those who do finish college, one-third or more will end up in jobs they could have had without a four-year degree. The BLS found that 37 percent of currently employed college grads are doing work for which only a high school degree is required.
It is true that earnings studies show college graduates earn more over a lifetime than high school graduates. However, these studies have some weaknesses. For example, over 53 percent of recent college graduates are unemployed or under-employed. And income for college graduates varies widely by major – philosophy graduates don’t nearly earn what business studies graduates do. Finally, earnings studies compare college graduates to all high school graduates. But the subset of high school students who graduate with vocational training – those who go into well-paying, skilled jobs – the picture for non-college graduates looks much rosier.
Yet despite the growing evidence that four-year college programs serve fewer and fewer of our students, states continue to cut vocational programs..."
There are a lot of successful billionaires who did not complete four yeas of college: Bill Gates, Steve Jobs, Michael Dell, Henry Ford, and Howard Hughes, just to name a few.
If you feel that the only purpose of attending high school or college is to get job-specific skills, then you are missing out on all the other aspects of those that teach you valuable life lessons, getting along with others, teamwork, communications, and other "soft skills" that aren't necessarily job-specific.
Teenagers entering college are still growing up, trying to figure out what they want to do with their lives, discovering new ideas, new ways of thinking, and networking with people of different backgrounds and cultures.
"...The U.S. economy has changed. The manufacturing sector is growing and modernizing, creating a wealth of challenging, well-paying, highly skilled jobs for those with the skills to do them. The demise of vocational education at the high school level has bred a skills shortage in manufacturing today, and with it a wealth of career opportunities for both under-employed college grads and high school students looking for direct pathways to interesting, lucrative careers. Many of the jobs in manufacturing are attainable through apprenticeships, on-the-job training, and vocational programs offered at community colleges. They don’t require expensive, four-year degrees for which many students are not suited..."
The skills shortage is real, but until employers are willing to pay people for what they're worth, the situation will not be resolved. The free market has a way to fix skills shortages. High demand raises salaries, and causes people to invest in high school and college education in part to vie for these positions. That is in part why medical doctors are paid so much.
"...The modern workplace favors those with solid, transferable skills who are open to continued learning. Most young people today will have many jobs over the course of their lifetime, and a good number will have multiple careers that require new and more sophisticated skills..."
A few years ago, I was hosting clients for dinner in Tucson. The sales rep had brought his daughter and her roommate along, as there was a shooting at their college campus and classes were canceled for the week. The daughter asserted, "In 18 months, I will no longer have to learn anything again. I will be done with school." Her roommate chimed in, "Ha! I am a year ahead of you, and only six months away from that!"
I was the bearer of bad news. "Ladies," I said, "you will have to get used to learning new things the rest of your lives." The highest ranking client at the table overheard me, and she re-iterated, "Ladies, that is probably the best advice I have heard in awhile. I suggest you heed it carefully."
A big part of high school and college education is to teach you how to learn on your own. Learn to read, search out information, take measurements, gather data, make plans, and ask the right questions. These are skills that are useful in a wide variety of careers.
Nicholas concludes with:
"...Just a few decades ago, our public education system provided ample opportunities for young people to learn about careers in manufacturing and other vocational trades. Yet, today, high-schoolers hear barely a whisper about the many doors that the vocational education path can open. The “college-for-everyone” mentality has pushed awareness of other possible career paths to the margins. The cost to the individuals and the economy as a whole is high. If we want everyone’s kid to succeed, we need to bring vocational education back to the core of high school learning."
I agree the educational system in United States is broken, but I am not sure I agree with everything that Nicholas writes in this article.
How do you define success? For some, it is based on their salary, or perhaps revenue they helped close for their company.
For others, their family life and the flexibility to handle work/life issues might be more important.
Still others look for certifications and awards from official agencies.
As a side gig, I sometimes do bartending on the weekends. Typically, these are for weddings or corporate parties.
I took weeks of bartender training and passed a three-hour exam to become state-certified to do so in Arizona. We Arizonans take our liquor seriously! If you think about it, bartending is just a notch below being a Pharmacist dispensing other drugs.
Surprisingly, some of my patrons will be condescending, "Don't you wish you can do more with your life than be a bartender?"
I am also certified "Laughter Yoga" instructor, and am called in at times to substitue for other instructors. Again, I took formal training and was certified to do so.
Again, some of my students will ask, "Don't you wish you could do more with your life than be a yoga instructor?"
In both cases, I would respond, "Dude, I earn six figures, and am happy to meet new people every week, how about you?" This usually shuts them up!
(For those interested, here are [my top 10 posts] which served as the basis of the interview!)
I am happy to be recognized externally and within IBM for my success as a blogger. Since I started blogging over 10 years ago, I have helped close over $4 Billion USD in revenue for IBM, written five books on IBM Storage, mentored dozens of other successful bloggers, and presented to thousands of clients at conferences, workshops and briefings.
Well, it's Tuesday again, and you know what that means? IBM Announcements! I am here in New York for the exciting news!
(FCC Disclosure: I work for IBM. This blog post can be considered a "paid celebrity endorsement" for the IBM z14 mainframe and DS8880 Storage System.)
In support of the [IBM z14] mainframe announcement, IBM has also disclosed R8.3 enhancements for the DS8880 Storage System. Here is a quick recap:
New Tier-1 Flash Capacities available for HPFE Gen2 drawers
IBM introduces the new Tier-1 flash card capacity 3.84 TB flash card. In the past, IBM DS8880 only supported Tier-0 cards that support 10 Drive Writes per Day (10 DWPD), with capacities 400, 800, 1600 and 3200 GB. The Tier-1 flash card only handles 1 DWPD, often dubbed "Read-Intensive" devices, but can actually handle about 90 percent of most production workloads.
zHyperLink™ drastically reduces the latency between the IBM z14 mainframe and the DS8880 storage systems. Traditional FICON paths through SAN switches or directors introduced about 140 to 175 microseconds of latency between systems. This new system is a direct cable, with 20 microsecond latency.
The I/O bays on the DS8880 used for HPFE Gen2 already have zHyperLink ports on them. This direct cable is limited to 150 meters, however, so plan accordingly.
Transparent Cloud Tiering
IBM already announced Transparent Cloud Tiering to IBM Bluemix, IBM Cloud Object Storage and the IBM TS7760 virtualization engine in R8.2.3 release. The new Release 8.3 of DS8880 now adds support for Amazon S3, providing yet another choice for where to migrate data sets to. IBM also adds replication, allowing the data set to be migrated to two separate target locations, for added availability, much like writing to separate ML2 tape cartridges.
Cascading FlashCopy is a feature that has existing for awhile now on IBM XIV and SAN Volume Controller platforms, so this is just a port of that concept over to the DS8880 microcode. Now, if you FlashCopy target can become the source of a follow-on FlashCopy request. You can make copies of copies. This applies to both the volume and data set level functions.
Why would anyone do this? Well, you might suspend your application at midnight and create a clean FlashCopy of a 24-by-7 ever-changing database. Then in the following morning, workers who need a static "midnight version" of the database now can use this as their source and perform additional FlashCopy requests for their own needs.
IBM DS8880 MES Support
MES is an abbreviation for "Miscellaneous Equipment Specification", one of the many Three Letter Acronyms [TLA] that doesn't help knowing what the words stand for. In short, an MES is a formal supported option to upgrade a piece of hardware that is already installed and running at a client location. IBM will offer MES to upgrade existing DS8880 systems to have the additional HPFE Gen2 drawers, and to upgrade the I/O bays to support zHyperLink connections.
(Final note: you might notice the change in upper and lower case. The IBM z14 (lower case) refers to the specific mainframe model, consistent with its predecessors the z13 and z13s, but the family name "IBM z Systems" has been shortened to "IBM Z®" (upper case). IBM Storage Systems and IBM POWER Systems were already upper case, so the mainframe guys just wanted to follow suit. I suspect "IBM i" will remain lower case, however.)
Well, it's Tuesday again, and you know what that means? IBM Announcements!
IBM Elastic Storage Server
Replacing the older "GSn" and "GLn" models, IBM announces the "Second Generation" GSnS and GLnS models (the second "S" stands for Second Generation), the "n" continues to refer to the number of storage drawers. All of these have a pair of POWER8 servers to drive amazing performance at a low price point.
The "GSnS" models are based on smaller 2U, 24-drive storage drawers, with 3.84 and 15.36 TB Tier-1 Read-intensive Solid-State Drives (SSD). The "GLnS" models are based on larger 5U, 84-drive storage drawers, with 4TB, 8TB and 10TB nearline (7200 rpm) spinning disk.
These new models have the latest IBM Spectrum Scale software pre-installed.
In addition to IBM's two existing Hyperconverged offerings--IBM Spectrum Accelerate for x86 servers, and IBM Spectrum Scale for x86, POWER and z Systems servers--IBM Power Systems now offers a third option. This integrated offering combines Nutanix's Enterprise Cloud Platform software with IBM Power Systems™ hardware to deliver a turnkey hyperconverged solution that targets critical workloads in large enterprises.
Nutanix is offered and will be defaulted/required on these Power® servers only:
While "Hyperconvergence" is still fairly new, and only about 1 percent of data centers have deployed this new technology, I am glad that IBM is a leader in this space with multiple offerings across both x86 and POWER systems platforms.
This week, I am presenting at the IBM Systems Technical University in Orlando, Florida, May 22-26, 2017. Here is my recap of the sessions on the morning of Day 5, the last day of the conference.
Integrating IBM Storage in Container Environments
Dr. Robert Haas, IBM CTO Storage for Europe, presented IBM Storage for Docker containers. These are different from containers in IBM Cloud Object Storage, and different from the Container Pools used in Spectrum Protect.
Robert gave an overview of IBM Spectrum Conductor, part of the IBM Software Defined Infrastructure (SDI) Spectrum Compute family of software products. The goal is to analyze large amounts of data, access these data efficiently, and protect the data, results and insights as intellectual property.
IBM Spectrum Compute comes in several offerings. IBM Spectrum LSF (Load Sharing Facility) manages long-running batch jobs for modeling, design and simulations. IBM Spectrum Symphony provides low-latency for risk analytics in the financial services sector. IBM Spectrum Conductor comes in two flavors. Conductor for Spark (CFS) manages Spark analytics. Conductor for Containers (CFC) handles Docker and Kubernetes containers.
Docker is the run-time platform. While there are other container run-time platforms like RKT and LXD, Docker is clearly the marketshare leader, growing 40 percent per year.
Statistics from the latest DockerCon2016 conference showed the most popular use cases and workloads for Docker. What can run in Docker: Lots of applications can be "containerized", including Redis, MongoDB, PostgreSQL, OracleDB, Java, to name a few. Docker is well established in enterprises, including service providers, healthcare, insurance and financial services, public sector, and technology firms.
Kubernetes, Mesos and Docker/Swarm are a layer above, as orchestrators. Spectrum Conductor for Containers uses Kubernetes and other open source tools to coordinate activity. Orchestrators restart failed applications, and can scale up or scale down the number of instances as needed. Orchestrators can manage groups of applications, across clusters on-premises and off-premises Cloud.
From a storage perspective, containers access storage like bare-metal operating systems, bypassing all of the layers normally associated with bloated Virtual Machine hypervisors. It also eliminates single root I/O virtualization (SR-IOV) that VMs use to compensate.
Persistent storage can be isolated, so that containers cannot see the files of other containers. This provides multi-tenancy.
Internal persistent storage (directory on host file system). However, if you move a container from one host to another, you may lose access to this internal storage.
External volume, manually mounted.
Volume driver plug-in REST API that automatically mounts it.
The fourth method is preferred. Plug-ins are available for IBM Spectrum Scale, GlusterFS, Portworx, Rancher Convoy, RexRay, and Contiv. The start-up Flocker have gone out of business last year.
The Docker hosts can attach to IBM Spectrum Scale in all of its supported offerings, including POSIX, NFS and SMB protocol. Containerized applications can move from one Docker host to another, and continue access the IBM Spectrum Scale namespace.
IBM has created the "Ubiquity Volume Service" that provides a consistent API for Docker and Kubernetes. This will use IBM Spectrum Control Base Edition to support IBM Spectrum Scale, Spectrum Accelerate, Spectrum Virtualize and DS8000 storage systems. For IBM Spectrum Scale, volumes are mapped to iSCSI volumes, filesets or directories. For other devices, volumes are mapped to block LUNs. Ubiquity is publicly available on GitHub.
Enterprise Applications for IBM Cloud Object Storage
Andy Kutner, IBM Cloud Architect, presented the various options available for NAS gateways that can front IBM Cloud Object Storage.
Ctera offers NAS gateways, and Endpoint agents for backup and Enterprise File Sync & Share (EFSS). This vendor targets Remote Office/Branch Office (ROBO) and small NAS consolidation that have less than 60 TB per office IBM is a reseller of Ctera, so you can get both Ctera and IBM COS from the same IBM sales rep.
Nasuni offers a global file system, accessible from any device, smartphone, tablet or desktop. They are focused on taking out EMC and NetApp NAS solutions. Performance at the edge, combined with capacity in the client's chosen Cloud (including IBM Cloud Object Storage or IBM Bluemix). Infinite snapshots replace backups, offering RPO of 1 minute for Disaster Recovery. Their global file system "UniFS" offers file locking.
Panzura focuses on Cloud Integrated NAS, File Distribution, and Collaboration. This can help eliminate "islands of storage". The File Distribution can be any type of file, but was originally designed for Media and Entertainment, such as videos. Collaboration employs EFSS features for workgroup shared file folders, such as CAD/CAM or engineering blueprints.
IBM Spectrum Scale can provide NFS and SMB access to files, and then move colder, less active data to IBM Cloud Object Storage, using Transparent Cloud Tiering feature. Spectrum Scale offers WAN caching across locations.
IBM COS now offers a native NFS v3 interface. This allows read/write NFS access, with S3 API read of the same content. Each file is mapped to a single object.
This is targeted for large scale archive, static-and-stable data, NFS-based backup software, and applications going through the transition from file-based to object-based. This is not intended for multi-site collaboration or primary NAS replacement. Regardless of the number of geographically dispersed IBM COS sites, the NAS can run on only one or two sites initially.
To provide NFS v3 support, IBM introduces new F5100 File Accessers, which talk to an IBM COS Accesser, which in turn acts on specific Vaults in the storage pools. The file-to-object mapping metadata is replicated on-premises across three File Accessers, and optionally replicated asynchronously to a second site for High Availability. S3 API can read access the file by file name, or by Object URI.
Initially, the "File Accesser" is only available as pre-built system, not as software-only.
There was not enough time to cover other solutions, including Avere, NetApp AltaVault, or Open Source S3FS.
This was a great event, just the right size, between 1,500 and 2,000 attendees. Similar IBM Technical University events coming up later this year:
This week, I am presenting at the IBM Systems Technical University in Orlando, Florida, May 22-26, 2017. Thursday evening, we had the "Meet The Experts" sessions. There were four: Storage, Power Systems, z/OS, and a fourth one focused on z/VM and Linux on z Systems. I was on the expert panel for Storage.
Mo McCullough was the emcee. Special thanks for Shelly Howrigon in her help with this event.
(Disclaimer: Do not shoot the messenger! We had a dozen or so experts on the panel, representing System Storage hardware, software and services. I took notes, trying to capture the essence of the questions, and the answers given by the various IBM experts. The answers from individual IBMers may not reflect the official position of IBM management. I leave out any references to unannounced plans or products. Where appropriate, my own commentary will be in italics.)
When will IBM offer a single pane of glass management for all of its IBM storage products?
IBM is working hard on this. Our strategy is to focus on IBM Spectrum Control as the primary answer. We have extended support across block, file and object, with support for IBM Spectrum Scale and IBM Cloud Object Storage System. We have also provided plug-ins for VMware, Cisco UCS Director, and OpenStack Horizon, for those who prefer those management systems instead.
What we really need are REST APIs!
Good point. IBM already has some REST APIs for the DS8000, XIV and Spectrum Protect, now that IBM has browser-based GUI across its entire product line, it is our strategy to offer REST API across our product line as well.
What is the next generation of ProtecTIER Data Deduplication going to look like?
IBM is focused on provided "data deduplication" for backup workloads directly through IBM Spectrum Protect backup software. IBM continues to sell IBM ProtecTIER.
(Virtual Tape Libraries like IBM ProtecTIER and Dell EMC Data Domain were created to handle the fact that many backup software back only were designed for tape drives and libraries. VTL was disk that pretended to be tape library. Now that IBM Spectrum Protect, NetBackup, Commvault, and all of the other modern backup products write natively to disk, object storage or Cloud services, there really isn't a need for VTL products any more.)
Why does IBM bother with all-Flash version of DS8000 when it already has IBM FlashSystem?
Different products for different workloads. IBM DS8000 offers unique support for z System mainframe FICON attachment and 520-byte block support for IBM i. IBM also offers all-Flash Elastic Storage Server, all-Flash SVC and Storwize products, that complement the IBM FlashSystem product line.
We like how XIV can hot-enable encryption, even with existing data on it. Why doesn't DS8000 offer this?
Two separate implementations. At the time IBM DS8000 encryption was designed, it was decided that the client needed to enable encryption before writing any data.
Will we see a spinning disk version of the FlashSystem A9000
Flash is now less expensive than spinning disk, I don't see why IBM would go backwards. The future is Flash.
We would like Spectrum Control to manage our Dell EMC Isilon
Yes, we have heard that from others. We are working on extending our third party support. Send in your cards and letters to help us prioritize. Or, better yet, submit a "Request For Enhancement" (RFE).
The difference between Tier 0 (Write Endurance) flash and Tier 1 (Read Intensive) flash is confusing, are there any plans in the IT industry to simplify this?
No, if anything it will get worse. Today, IBM's Tier 0 is 10 Drive Write Per Day (DWPD), and Tier 1 is 1 DWPD. Other SSD drives offer 2, 3, 5, 10, 15 and 25 DWPD. As people buy more Flash, and less disk, expect more differentiation in this area.
We would like to tune Easy Tier on the Storwize products
Understood. IBM typically implements new features on the DS8000 platform first, then rolls them over to Spectrum Virtualize. The ability to influence allocation order, pin or avoid tiers, and have application API to influence the placement are already in DS8000.
What will the future of Storwize look like?
We don't have enough time to cover that in this meeting.
Recently, you raised the maximum Storwize FlashCopy background copy rate from 64 MB/sec to 2 GB/sec, but is that realistic?
The setting provides the background task a target "grains per second" to try to achieve. It may not be possible depending on your configuration and the number of concurrent tasks. Your Storwize may be so busy with background activity that it won't take host I/O.
We have been giving you our wishlist, but are there any questions the IBM experts have for the audience
Yes, are there any clients being asked to secure storage against Ransomware and insider threats from disgruntled employees?
(Several hands went up, and we collected their names to have further discussions.)
How should we assign business value to data?
IBM Spectrum Virtualize allows you to assign metadata tags to files, so that these can be used to drive different policies.
(The process of assigning business value is often called "Data Rationalization" and is part of ILM, BC/DR, and Data Governance efforts.)
I am concerned that AES 256 encryption is not good enough now that there is Quantum Computing.
It will be decades before Quantum Computing will be good enough to break these codes.
Will Blockchain drive huge or unique storage requirements?
No. The entries are small. You are appending small transactions to the end of existing ledgers. Nothing unique or different.
Were there any topics not adequately covered at this conference?
IBM didn't have much to offer for Spectrum Compute family of software, the Software Defined Infrastructure (SDI) that runs on both x86 and POWER systems. This should be done under the POWER brand, but many clients use Spectrum Compute with x86 servers. Ironically, Spectrum Compute products are managed under the Storage division, since Spectrum Compute and Spectrum Storage work well together.
We would like Storwize's clever NPIV to be implemented in all of the other IBM arrays, starting with DS8000.
That probably won't happen, as they are different architectures. Whereas Storwize and the rest of IBM Spectrum Virtualize family were designed for nodes to fail, and take their ports down with them, the DS8000 has independent I/O bays that continue to run independent of either POWER8 node. Likewise, FlashSystem 900 has similar separation between the FCP adapters and the processing nodes.
Can we have consistent licensing across the entire IBM Spectrum Virtualize set of products, please?
We have a task force to investigate this, and will gladly add your name to the list for input and feedback.
While the conference continues Friday morning, for many attendees, this was the last event.
IBM Spectrum Scale was formerly called GPFS and has been around since 1998. I am glad it was renamed, as GPFS suffered from "guilt by association" with other file systems, AFS, DFS, XFS, ZFS, and so on.
Spectrum Scale does so much more, supports volume, file and object level access, supports POSIX standards for Windows, AIX and Linux, support Hadoop and Spark with 100 percent compatible HDFS Transparency Connector, support NFS, SMB and iSCSI protocols, as well as OpenStack Swift and Amazon S3 object based access.
Initially designed for video streaming and High Performance Computing (HPC), IBM has extended its reach to work in a variety of workloads across different industries. More than 5,000 production systems are running at client locations.
IBM Spectrum Protect solution design: Server, Deduplication and Disaster Recovery decisions
Dan Thompson, IBM Storage Software Technical Sales Specialist, presented this session.
To make it easier to deploy, IBM Spectrum Protect now has a set of tested "blueprints" that are organized into small, medium and large. Find the one that fits your needs, and it will tell you exactly how the server should be configured. Dan recommends having a "test system" to try out new releases of IBM Spectrum Protect.
For multiple server configurations, Dan recommends adopting a standard naming convention, and to make use of Enterprise Configuration and server-side Client Option Sets. You may want to consider discrete instances for special non-backup functions, like library manager or Operations Center hub server, which allows you to upgrade more aggressively without affecting your backup clients.
If you plan to run multiple Spectrum Protect instances on the same VMware host, set the DBmemPercent to avoid having DB2 consume all of the memory, which will interfere with out Spectrum Protect instances.
For clustered servers, IBM supports Active/Passive, Active/Active, Many/One, and Many/Few configurations. You can mix and match these as needed.
For data spill remediation, consider NIST 800-88 data shredding. This depends on the type of storage media used.
IBM Spectrum Protect for Data Retention, formerly called System Storage Archive Manager (SSAM), offers For Non-erasable, Non-Rewriteable (NENR) enforced Immutability protection. (This used to be called Write-Once-Read-Many or WORM for short, but since WORM applies only to tape and optical media, and IBM Spectrum Protect now supports Flash, Disk, Object Storage and Cloud repositories, IBM has adopted the term NENR instead). Third party KPMG has certified IBM Spectrum Protect for Data Retention meets to their satisfaction the requirements for SEC 17a-4 regulations.
When sizing your server, Dan recommends that you always "over-size" it and grow into it. Use the published "Performance Optimization Guide" to help. Monitor the server and storage using OS and device specific monitoring, in combination with IBM Spectrum Protect reports.
If you are still on BC Tiers 1 or 2, transmitting tapes to a remote vaulting facility or secondary data center, consider upgrading to BC Tier 3 at least. This can be done via electronic vaulting to an Automated Tape Library (ATL), Virtual Tape Library (VTL) or IBM Cloud Object Storage, or a Cloud service provider such as IBM Bluemix or Amazon Web Services. This can be supplemented using DB2 HADR for the IBM Spectrum Protect database.
While Spectrum Protect server can run bare-metal or as a VM, the VM instance will not have support for FCP-based tape or Virtual Tape Library. Many people are moving off tape, especially VTL, and using native Disk, Directory or Cloud container pools instead.
Lastly, take advantage that Operations Center can view all Spectrum Protect servers across all locations. This can be helpful.
Enabling Mission Critical NoSQL workloads using IBM trillions of operations technology
TJ Harris, from the IBM Storage CTO office, and Scott Brewer, FlashSystem Team Lead, co-presented this session.
They gave a background on NoSQL, the most popular being MongoDB. The IT industry estimates that NoSQL will grow 38 percent CAGR from 2015-2020.
The problem occurs when NoSQL applications go through a full file system stack to work with low-latency devices like Flash, especially when the writes are small, often just a few dozen bytes to 100 KB. Fortunately, IBM Research has created the "Trillions of Operations" project to explore ways to take reduce the software stack, and make use of NVMe protocol.
The top three challenges for NoSQL deployments are: (a) Cost, (b) Data management and retention, and (c) Data relevancy.
To enable innovation, MongoDB offers a "Storage Engine API" that allows others to compete at this space. Currently MMAP v1 and WiredTiger are supported. IBM Research implemented its "Trillion Operations" project as a plug-in to this API, optimized for high rates of ingest for data. Compared to Facebook's RocksDB, IBM was 14x faster write, and 2.1x faster read.
Another challenge is coordinate backups and disaster recovery when applications mix traditional RDBMS with these new NoSQL databases.
The week is nearly over, and I can see the light at the end of the tunnel. Everyone had a great time last night's event at the Universal City Walk and Blue Man Group.
This week, I am presenting at the IBM Systems Technical University in Orlando, Florida, May 22-26, 2017. Here is my recap of the sessions on the morning of Day 4.
Configurable IBM Spectrum Scale
Kent Koeninger presented IBM Spectrum Scale software, which Kent refers to as "Configurable Spectrum Scale" (or CSS for short), as opposed to the pre-built system known as Elastic Storage Server (ESS).
Why choose CSS versus ESS? Lower entry price. You can start with just two single-socket servers and a drawer of disk.
IBM Spectrum Scale was formerly called IBM General Parallel File System (GPFS). Many who tried earlier versions of GPFS found it difficult to configure, because it only had a command line interface. Now, Spectrum Scale has a fully-functional GUI, and clients have been able to install and configure Spectrum Scale in just 30 minutes!
How big can Spectrum Scale grow? As much as your budget can afford! With an architecture that can support YottaBytes of data and 900 quintillion files, you won't hit any limits anytime soon.
There are some unique capabilities of ESS not available in CSS. For example, ESS offers Spectrum Scale Native RAID (erasure coding) with fast rebuild times, and ESS is certified for SAP HANA. You can combine any combination of CSS and ESS in the same Spectrum Scale to create a "data lake" for mixed workloads.
A good use case for Spectrum Scale, either CSS or ESS, is backup. Kent explained why it is an excellent option to store backups with enterprise backup software such as IBM Spectrum Protect or Commvault.
VersaStack - Hybrid Cloud like no other
This session was jointly presented by Chris Vollmar, IBM Storage Architect, and Brent Anderson, Cisco Global Consulting Systems Engineer. IBM and Cisco have been partners for more than 25 years.
VersaStack combines Cisco UCS x86 servers, Cisco Nexus and MDS switches, and IBM FlashSystem or Spectrum Virtualize storage.
What if you have a SAN Infrastructure built entirely from IBM b-type or Brocade-based switches? Cisco supports their SAN switches for this, but nobody has tested VersaStack in this combination, and UCS Director does not manage this combination, so IBM does not support this. Instead, for this situation, IBM recommends doing external connection via Ethernet, or using direct-attach configurations.
The Cisco Validated Design spends four months testing, and gives you bulletproof process to deploy the solution.
There is a difference between Cisco UCS Manager and UCS Director. UCS Manager is available at no additional charge, but only manages the Cisco x86 servers. UCS Director is optionally extra priced, and manages Cisco servers, Cisco networking, and IBM Spectrum Virtualize storage.
Brent explained the benefits of UCS Management through policies and profiles.
Chris covered Cisco CloudCenter, which the Cisco team shortens to just "C3". IBM Spectrum Copy Data Management can be used to move snapshots of data between on-premises and off-premises Cloud to help in Hybrid Cloud configurations.
How to Design an IBM Spectrum Scale solution
Tomer Perry, IBM Spectrum Scale I/O Development, presented this session.
For those who want to bring up a quick IBM Spectrum Scale environment to play around with, you can do this in as little as 30 minutes. But to design a mission critical deployment, additional requirements may need to be addressed. You may need to consult with not just storage admins, but also application owners, network admins and security personnel.
Large companies have hundreds or thousands of applications, so Tomer recommends to group these into "Workload families", based on data set types, access patterns and performance requirements. For NAS take-out, 80 percent of NAS I/O is "get attribute" that can easily be served directly from cache memory.
For each workload family, you may need to decide on snapshots, quotas, namespace (bind mounts, symlinks, etc.), security (ACL, encryption), estimated capacity, replication BC/DR, backup and ILM requirements.
Unless this is completely greenfield deployment, the existing infrastructure needs to be evaluated. This includes the LAN and WAN network topology, name resolution (DNS), time services (NTP), Authentication (AD, LDAP, NIS, Keystone), Keyserver (IBM SKLM), Monitoring and Migration requirements.
Tomer suggests designing the environment in this order: Cluster, File System, Storage Pools, Fileset, Replication, and finally Monitoring.
Generally, you need three NSD servers per cluster. For those licensing Spectrum Scale Standard Edition by the socket, you may be tempted to put everything into one big cluster. The new capacity-based Spectrum Scale Data Management Edition eliminates that concern, so Tomer recommends having separate computer clusters and storage clusters, connected by cross-cluster mount. All nodes in a cluster are considered an "ssh" administration domain.
A single Spectrum Control namespace can support up to 256 file systems. There are various reasons to have multiple file systems: block size, backup/recovery, snapshot, quotas, and cross-cluster isolation. If a file system gets corrupted, it will not affect other file systems. In an internal test, an "fsck" on 1 billion, 1 PB of data file system took only 30 minutes to repair.
Storage Pool design can separate metadata from content, and workloads can be separated to different storage media. With ILM, HSM and TCT, you can move colder data to Cloud, Object Storage, Spectrum Protect or Spectrum Archive.
Filesets are tree branches for each file system. IBM Spectrum Scale supports both dependent and independent filesets. Filesets can be used for Non-erasable, Non-Rewriteable (NENR) Immutability, policies, quotas, snapshots. Consider using a fileset instead of carving off a new file system.
Spectrum Scale offers both synchronous and asynchronous replication. For Synchronous, the ReadReplicaPolicy can be set to default, local or fastest. For Asynchronous, there are a variety of AFM modes (Read-only, Local-Update, Single-Writer, Independent-Writer, and Disaster Recovery). You may need to decide if your AFM gateways are dedicated or collocated. You will need to tune your TCP buffers for WAN performance to get the RPO you desire.
The nice thing about IBM solutions is that you can start small, and grow big. In all of these examples above, IBM offers sizes to match nearly any IT budget.
This week, I am presenting at the IBM Systems Technical University in Orlando, Florida, May 22-26, 2017. Here's my recap of the sessions of Day 3.
Ethernet-only SANs -- Myth or Reality?
Anuj Chandra, IBM Advisory Engineer, presented an excellent overview of Ethernet-based SANs. He started with a quick history of Ethernet, starting with Robert Metcalfe's original drawing for his concept.
In the past, Ethernet was used for email and message transfer, and so dropped packets were tolerated. However, with the use of Ethernet for SANs, many standards have been adopted to make Ethernet networks more robust. These meet requirements for Flow Control, Congestion management, low latency, data integrity and confidentiality, network isolation, and high availability.
These standards are known as IEEE 802.1Q "Data Center Bridging", including 8012.Qbb Priority Flow Control, 802.1Qaz Enhanced Transmission Selection, 802.1Qau Congestion Notification. There is also the IETF Transparent Interconnection of Lots of Links (TRILL) to replace Spanning Tree Protocol (STP). All of these features are negotiated between endpoints server and storage. Ethernet that supports these new standards is often referred to as "Converged Ethernet" since it handles both traditional email/message traffic as well as SAN data traffic.
In addition to 1GbE and 10GbE, we now have 2.5, 5, 20, 40, 50, 100 Gb Ethernet speeds. By 2020, Anuj estimates over half of all Ethernet ports will be 25 GbE or faster. Amazingly, some of these can work on existing 10BASE-T cables.
Anuj also covered Remote Direct Memory Access (RDMA), and the RDMA-capable Network Interface Cards (RNIC) that support them. In one chart, shown here, Anuj explained Infiniband, RDMA over Converged Ethernet (RoCE) and RoCE v2, and Internet Wide Area RDMA Protocol (iWARP).
While many of these enhancements were intended for Fibre Channel over Ethernet (FCoE), the beneficiary has been iSCSI. Now there is iSCSI Extensions for RDMA (iSER) to take even more advantage of these changes, and can work with Infiniband, RoCE or iWARP. All of these networks can also be used as the basis for NVMe over Fabric (NVMeOF).
Ethernet is the backbone of Cloud usage, and IBM is well positioned to take advantage of these new networking technologies.
Digital Video Surveillance solutions for extended video evidence protection
Dave Taylor, IBM Executive Architect for Software Defined Storage solutions, presented this session on Digital Video Surveillance (DVS).
Most video surveillance is either analog-based, going to standard VHS tapes, or file-based. Sadly, security guards that watch live camera feeds lose their attention span after 22 minutes.
There are an estimated 72 million cameras globally, with 1.5 million more every year.
City governments spend 57 percent of their budget on "public safety". This can include body cams for police departments. Taser International, now called AXON, dominates the body-cam market.
City budgets may not be prepared to store all of this video content into a cloud that complies with Criminal Justice Information Services (CJIS) standards. These Cloud services tend to be more expensive, as the videos must be treated as evidence, tamper-proof, and with appropriate chain of custody.
DVS is not just storing movies. IBM offers Intelligent Video Analytics. It is important to be able to derive insight and actionable response.
Storage capacity adds up quickly. Standard 1080p (1920 by 1080 pixel) camera generates 2.92 GB per hour, 70 GB per day, and over 2TB per month. If you have 1,000 cameras, that's over 2PB of data.
For xProtect servers running Windows, the Tiger Bridge Connector can be used to move the video files to either IBM Spectrum Scale or IBM Cloud Object Storage.
Deep Dive into HyperSwap for Active-Active applications and Disaster Recovery
Andrew Greenfield, IBM Global Engineer for Storage, explained the different ways HyperSwap is implemented across the IBM storage portfolio.
For IBM DS8000, HyperSwap is based on Metro Mirror synchronous replication. In the event that the primary DS8000 fails, the host server can automatically re-direct all I/O to the secondary DS8000. This is often referred to as "High Availability" (HA), and in some cases can serve as Disaster Recovery.
For IBM Spectrum Virtualize products, including SAN Volume Controller (SVC), FlashSystem V9000, Storwize V7000 and V5000 products, as well as Spectrum Virtualize sold as software, the implementation is different.
Previously, SVC offered Stretched Clusters, which put one node in one site, and a second node at another site, which allows for an Active/Active configuration. Unfortunately, the nodes in FlashSystem V9000 and Storwize are "connected at the hip", effectively bolted together, so putting separate nodes in different locations was not possible. To solve this, IBM developed HyperSwap that allows one node-pair to replicate across sites to another node-pair in the same Spectrum Virtualize cluster.
However, even though it is called "HyperSwap", it is not implemented in any way similar to the DS8000 method. Instead, Spectrum Virtualize uses the Global Mirror with Change Volumes to replicate data between sites.
IBM Storage and VMware Integration
This session was co-presented by Brian Sherman, IBM Distinguished Engineer, and Steve Solewin, IBM Corporate Solutions Architect.
For nearly two decades, IBM is a "Technology Alliance Partner" with VMware. To provide consistent integration to all the features and functions of VMware, IBM Spectrum Control Base Edition (SCBE) is provided at no additional charge for IBM DS8000, XIV, FlashSystem and Spectrum Virtualize products.
SCBE is downloadable as an RPM for RedHat Enterprise Linux (RHEL) can run bare-metal or as a VM.
For those using Hyper-Scale Manager, it will automatically install a special A-line-only version of SCBE. It will install SCBE, but it will only manage the A-line products (FlashSystem A9000, FlashSystem A9000R, XIV and Spectrum Accelerate).
Storage admins can define "storage services" that can be assigned to vCenter. This allows VMware admins to allocate storage in self-service mode.
After the meetings were over, IBM had a special event at the Universal City Walk to enjoy some drinks, food, and conversation, and to watch Blue Man Group.
This week, I am presenting at the IBM Systems Technical University in Orlando, Florida, May 22-26, 2017. Here's my recap of the afternoon sessions of Day 2.
IBM Spectrum Protect deep dive into Container Storage Pools
Ron Henkhaus, IBM Certified Consulting IT Specialist, presented the new Spectrum Protect concept of "Container Pools" that can either be "Directory Pools" on SAN or NAS-based disk storage, or "Cloud Pools". Container pools can contain deduplicated and non-dedupe data.
Ron cautioned that directory pools should not be placed on the same file system as your Spectrum Protect database or logs. Also, best practice for any directory pool is to assign an "overflow" pool to any non-directory pool, such as disk, tape or cloud container.
Cloud pools can use either OpenStack Swift, V1 Swift, Amazon S3 protocol, Amazon Web Services, IBM Bluemix, and IBM Cloud Object Storage. You can pre-define the vaults and buckets in the configuration.
For off-premises Cloud pools, the data is encrypted by default. For other container pools, encryption is optional. Performance to Cloud pools have been improved by using "accelerator storage", basically a disk cache to collect data before sending over to the Cloud pool. Backups to Cloud pools can reach 8 TB per hour. Restore times varies from 500 to 1500 GB per hour.
Container Pools were designed for the new "Deduplication 2.0" feature introduced in version 7. Traditional Dedupe 1.0 to Device Class FILE is still available, but not recommended.
Version 7.1.6 changed the compression algorithm from LZW to LZ4. In all cases, Spectrum Protect performs these actions in this order: deduplication, compression, encryption. Data that is encrypted by the Spectrum Protect client is therefore not deduped.
The "Protect Storage Pool" command can replicate a directory pool to either a remote directory pool or Cloud pool. In addition to this remote replication, you can copy a directory pool to tape to offer air-gap protection against ransomware. Such tapes are considered part of the "Copy Container Pool". In the event of directory pool corruption, the data can be repaired from either replication or tape.
IBM Aspera can now be used for replication, using SSL and AES-128 bit encryption. If your latency is greater than 50 msec, and have more than 0.5 percent packet loss, Aspera might help. This is available for Linux on x86 platforms running v7.1.6 or higher.
For existing customers, IBM Spectrum Protect allows you to convert your FILE, VTL and TAPE device class pools to directory or Cloud pools.
Introduction to IBM Cloud Object Storage (powered by Cleversafe)
In 2015, IBM acquired Cleversafe, recognized as the #1 Object Storage vendor. Their flagship product was officially renamed to the IBM Cloud Object Storage System, which some abbreviate informally as IBM COS. IBM offers the IBM Cloud Object Storage System in three ways: as software, as pre-built systems, and as a cloud service on IBM Bluemix (formerly known as SoftLayer).
Since then, IBM has been busy integrating IBM COS into the rest of the storage portfolio. I explained how IBM COS can be used for all kinds of static-and-stable data, but not suited for frequently changed data, such as Virtual machines or Databases.
Object storage can be access via NFS or SMB NAS-protocols using a gateway product, like IBM Spectrum Scale, or those from third-party partners like Ctera, Avere, Nasuni or Panzura. It can also be used as an alternative to tape for backup copies, and is already supported by the major backup software like IBM Spectrum Protect, Commvault Simpana, or Veritas NetBackup.
While other cloud service providers have offered data storage in the cloud, this new offering also allows hybrid configurations with geographically dispersed erasure coding.
Unlike RAID which protects against the loss of one or two drives, erasure coding can protect against a larger number of concurrent failures. For example, using an Information Dispersal Algorithm (IDA) of "7+5", where seven pieces of data are encoded on twelve independent disks, the system can lose up to five disk drives without losing any data.
Combining this with Geographically Dispersed Configuration across three or more sites means that you can lose an entire data center, four of the twelve disks, and still have instant full access to all of your data from eight drives at the other locations. In the graphic, you see two on-premise data centers combined with a third location in IBM SoftLayer.
New Generation of Storage Tiering: Simpler Management, Lower Costs, and Improved Performance
With ever changing amounts of storage, it is hard to find metrics that are consistent year to year. Fortunately, we found I/O density as the metric to focus my efforts, armed with real data from Intelligent Information Lifecycle Management (IILM) studies done at various clients. From that, I was able to talk about storage tiering on three fronts:
Storage tiering between Flash and disk. IBM FlashSystem and IBM Easy Tier on DS8000 and Spectrum Virtualize family for hybrid Flash-and-disk configurations.
Storage tiering between disk, tape, and Cloud. HSM and Information Lifecycle Management (ILM) on Spectrum Scale, Elastic Storage Server (ESS), Spectrum Archive and IBM Cloud Object Storage System.
Storage tiering automation across your entire environment. IILM studies can help identify a target mix of Tier 0, Tier 1, Tier 2 and Tier 3 storage. IBM Spectrum Storage Suite and the Virtual Storage Center (VSC) can recommend or perform the movement of LUNs to more appropriate tiers, based on age and I/O density measurements.
It's hard to say what the correct sequence of presentations should be. Some thought it might have been better for my talk on IBM Cloud Object Storage System prior to Ron's talk on Cloud container pools, but perhaps hearing Ron first helped drive more interest to my session.
