Well, it's Tuesday again, and you know what that means? IBM Announcements!
This week, IBM announces the second generation of Storwize V5000 flash and disk storage systems. There are the V5000F All-flash configurations, as well as the V5000 that can support a variety of flash and spinning disk drives.
There are three models:
The V5010 has dual 2-core/2-thread processors and 16GB of cache. It supports thin provisioning, FlashCopy, Easy Tier, and remote mirroring. The base unit includes 1 GbE Ethernet ports for iSCSI host connectivity, with options to add 16GB Fibre Channel, 12Gb SAS, and 10GbE iSCSI/FCoE as well.
The 2U controllers and expansion enclosures can hold either 24 small 2.5-inch drives, or 12 larger 3.5-inch drives. A single control enclosure has two active/active IBM Spectrum Virtualize nodes, and can attach up to 10 expansion enclosures for a maximum of 264 drives.
The V5020 unit has dual 2-core/4-thread processors and up to 32GB of cache. It supports everything the V5010 does, plus encryption. The encryption is done via the Intel AES-NI instruction set to eliminate the need for special "self-encrypting drives" (SED) that other storage devices may require.
The V5030 has dual 6-core/4-thread processors and up to 64GB of cache. It supports everything the V5010 and V5020 do, plus Real-time Compression and external virtualization. The Real-time Compression can achieve up to 80 percent space savings, representing a 5:1 compression ratio.
Each control enclosure can attach to 20 expansion enclosures, which can support 504 internal drives per controller, and up to 1,008 with two controllers (four Spectrum Virtualize nodes) clustered together. This is in addition to the drives in external storage systems virtualized.
Well, it's Tuesday again, and you know what that means! IBM Announcements!
Today also happens to be [Election Day] in the United States, and some have questioned IBM's logic of making major storage announcements on Election Day. During the campaigns, a major theme was to help Small and Medium size businesses, because these are the engines of economic growth and improved employment.
Hopefully, you all saw today's Launch Webcast on these announcements, but in case you missed it, waiting in line at the polling station to cast your vote, or caught without electricity or Internet access from [Superstorm Sandy], it is now available [On-Demand].
The 2U control enclosure can have up to four additional 2U expansion enclosures, for a maximum of 120 drives, or 180TB of raw disk capacity. Like the Storwize V7000, the Storwize V3700 supports a [large number of servers and operating systems.]
Many of the features you already know from the Storwize V7000 are carried forward:
1GbE iSCSI + 8GbFC
8GbFC, 10GbE iSCSI/FCoE, Statement of Direction for 6Gb SAS
8GB per canister
4GB per canister, upgradeable to 8GB
Up to 4 control enclosures in a clustered system, each with up to 9 expansion enclosures
Up to 4 expansion enclosures
Maximum Number of drives/TB
Up to 120 drives/180TB
RAID levels supported
GUI, CLI, SMI-S API
GUI, CLI, SMI-S API
Internal (included), external (optional)
Internal only (included)
Non-disruptive data migration
One-directional (migrate to Storwize V3700, included)
Statement of direction
Up to 256 targets (included)
Up to 64 targets (included) Statement of Direction for optional 2,040 targets
Metro Mirror and Global Mirror (optional)
Statement of Direction (optional)
The IBM Storwize V3700 is offered at attractive leasing options through IBM Global Financing.
IBM LTO-6 drives and midrange tape libraries
Last month, IBM's [Tape and Storage Hypervisor Announcements] included LTO-6 for the enterprise-class TS3500 tape library. Today, the LTO-6 support is complete with support for midrange tape drives and libraries.
There are two tape drive models. The TS2260 is based on the half-height drive, intended for occasional 9-to-5 usage. The TS2360 is based on the full-height drive, intended for 24x7 access. These drives can read LTO-4 and LTO-5 tape cartridge media, and can write LTO-5 cartridge media. The new LTO-6 tape cartridge media is expected to be available next month.
In addition to the IBM TS3500 Enterprise Tape Library, LTO-6 is now supported on all of the midrange tape libraries: TS2900, TS3100, TS3200 and TS3310.
IBM Linear Tape File System Library Edition V2.1.2
There are two levels of [Linear Tape File System], or LTFS for short. The first is the Single Drive Edition (LTFS-SDE), which allows you to attach an LTO-5, LTO-6 or TS1140 tape drive to a single workstation, and allow you to mount tape cartridges as easy as mounting USB memory sticks. This presents a full file system view that allows you to read, edit, create, and even drag-and-drop files to other file systems. The LTFS-SDE driver is available for Windows, Linux, and Mac OS.
The second is the Library Edition (LTFS-LE), which allows you to mount the entire tape library as a file system. Each tape cartridge in the library is presented as a subdirectory folder, that you can access like any file system on disk. This was only available for Linux systems, which could then export the files through NFS, FTP or HTTP protocols to other clients. Now, with release v2.1.2, LTFS-LE supports Windows servers, so that you can share the files with other clients through CIFS as well.
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.)
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.
Well, it's Tuesday again, and you know what that means? IBM Announcements!
IBM ProtecTIER TS7650G model DD6 supports File System Interface (FSI)
The IBM ProtecTIER Data Deduplication appliance (TS7620) and gateway (TS7650G) support three protocols used by major backup software products:
VTL - Virtual Tape Library. Originally, backup software products were designed exclusively to work with tape drives and libraries. To introduce disk-based storage and data deduplication, the easiest way was for disk-based systems to pretend to be a tape library. Hence, "Virtual Tape Library" acts just like a physical tape library.
OST - OpenStorage Technology API, a proprietary interface used exclusively by the Veritas NetBackup software to talk to disk-based backup repositories.
FSI - File System Interface, which are your familiar NAS interfaces like NFS and SMB (formerly known as CIFS). Some backup software like Commvault Simpana are optimized for NAS storage pools.
In the past, FSI was limited to the single-controller models. This is because having an active/active file system sharing was very complicated to implement.
In the new DD6 dual-controller model, you can now run two independent FSI instances, each controller owns its own set of files. To learn more, see the IBM Press Release [IBM ProtecTIER DD6 supports FSI].
IBM TS3000 System Console enhancements
The Tape Storage System Console (TSSC) is a console that allows administrators to manage up to 24 systems in tape libraries (such as TS3500 and TS4500) and virtual tape systems (such as TS7720T and TS7650G). The new features include:
Error-initiated problem reporting, often called "Call Home" support, with staged, error-specific data gathering for support
Automatic wellness checking
Remote services such as remote monitoring support and call-in capability with authenticated access through a modem or broadband, including file transfers and multiple connections with attached systems
IBM offers two sets of products for entry-level and midrange disk systems:
Storwize V7000 and V5000 products are optimized for random-access workloads like Virtual Machines (VMs), Databases, Email and other Online Transaction Processing (OLTP).
The DCS3860 and DCS3700 are optimized for sequential throughput, like video streaming, batch processing or big data analytics.
Prior to this announcement, the DCS3700 and DCS3860 supported 4TB and 6TB Nearline 7200 rpm drives, and 800GB and 1.6TB Solid-State Drives (SSD). Obviously, it doesn't make sense to offer SSD on sequential-oriented solutions. To align better with this worldview, IBM is discontinuing the SSD options, and adding a new 8TB Nearline drive option.
IBM Spectrum Control Advanced Edition and IBM Virtual Storage Center
Earlier in my career, I was the chief architect of what is now called IBM Spectrum Control. If you still have IBM Tivoli Storage Productivity Center (TPC) Standard Edition V4.x products, you can now migrate to IBM Spectrum Control Advanced Edition V5.2 by ordering a trade-up part number through Passport Advantage.
IBM Virtual Storage Center (VSC) Entry uses a per-TB pricing model. This is a discounted version of VSC "Classic" for those with four or fewer SAN Volume Controller (SVC) node pairs, and 500 TB or less managed storage capacity per enterprise.
I love Hollywood movies where the main character joins the [Witness Protection Program]! For those not familiar, this is when a person witnesses a horrible or obscene crime. To protect the witness from the criminals, the US Government would change your name, create a new identity, and move you to a new city until the trial is over. While this hides the witness from the bad guys, it also means losing touch with all your friends and family.
I mention this because every time IBM renames an existing product, modifies the code to meet IBM standards, translate to other international languages, and all the other activities needed to [assimilates the product into the IBM "Borg"], it is very similar to joining the Witness Protection Program.
(Internally, we refer to this renaming and assimilating as "blue-washing", not to be confused with the traditional definition of "bluewash" -- To tout a corporation's commitment to social responsibility, and to use this perception for public relations and economic gain; to present a humanitarian front in this manner, which IBM also does. See this article [Sesame Workshop and IBM Watson Team Up to Advance Early Childhood Education] for an example.)
Last November 2015, [IBM acquired Cleversafe] for $1.3 Billion US dollars because Cleversafe has the brand name recognition as the #1 Object Storage vendor the past two years in a row (2014 and 2015). Unfortunately, Cleversafe has "witnessed" a huge rise in obscene profits and revenues, and is now joining the "Witness Protection Program".
Renaming Cleversafe software, pre-built appliance hardware, and related cloud services to [IBM Cloud Object Storage System] is like someone acquiring the Coca-Cola company and renaming their namesake soft drink product to "Brown Carbonated Sugar Liquid", which adults might shorten to "Bro-Carbo" and the kids would nickname "Sugar-Liq".
(FCC Disclosure: I work for IBM. This blog post can be considered a "paid celebrity endorsement" for IBM Storage products. I have no financial interest in the Coca-Cola Company, CBS Television, Paramount Pictures, or Warner Bros. I have no knowledge of any IBM's future plans in acquiring any beverage-based manufacturing or bottling companies. I use Coca-Cola® merely as a well-recognized brand for illustrative purposes.)
Honestly, I don't know if "IBM Cloud Object Storage System version 3.8" offers any new features over "Cleversafe 3.7", or if the numbering change was just to help avoid confusion with existing v3.7 clients.
The IBM 3592 Tape Controller Model C07 which provides FICON access for mainframe attachment did not meet the Restriction of Hazardous Substances [RoHS] directive. This is the directive to not have lead-based paint or other hazardous substances in the paint, plastic or other materials in IT equipment.
IBM had a tough business choice. Either fix it, or stop selling it. Our mainframe clients just don't use physical tape anymore. Instead, IBM offers IBM Virtual Tape Systems (TS7720, TS7720T and TS7740) as well as the IBM ProtecTIER TS7650G Mainframe Edition.
In journalism, this is called [burying the lede]. IBM has combined the world's fastest storage, IBM FlashSystem 900, with IBM FlashSystem® A9000/A9000R Software V12.0, based on IBM Spectrum Accelerate and XIV v11 software technology.
This new software has many of the features you love from IBM Spectrum Accelerate and XIV, but adds excellent data footprint reduction. First, we eliminate repeated patterns, then apply data deduplication, and finally apply advanced compression.
This combination works great for Virtual Desktop Infrastructure, Virtual Machines for traditional applications, and even databases. Since this applies to all data, the models are priced based on their "effective capacity" based on 5.26x reduction. Different data dedupes or compresses at different rates. Your mileage may vary.
Two models were announced:
FlashSystem A9000 - This is an 8U rack-optimized solution that has three 2U x86 servers combined with a 2U drawer of FlashSystem 900 with a nice bezel on the front. This can fit into any standard 19 inch rack. Since FlashSystem offers 1.2TB, 2.9TB and 5.7TB IBM Microlatency modules, the FlashSystem A9000 is offered in 60TB, 150TB and 300TB effective capacities. Performance is at least 250 microsecond latency, up to 4.5 GB/sec throughput and 50,000 IOPS.
FlashSystem A9000R - The "R" on the end refers to "Rack". Instead of something that slides into an existing rack, the A9000R is a free-standing 19-inch wide rack with two to six flash enclosures. Each flash enclosure will have two x86 servers running the IBM FlashSystem A900R Software v12.0, and one FlashSystem 900 drawer. IBM offers both 150TB and 300TB effective capacity per flash enclosure, based on the 2.9TB and 5.7TB IBM Microlatency modules. Performance is at least 250 microseconds, up to 18 GB/sec throughput and 2 million IOPS.
Some have called these new models the "All-Flash" version of XIV, in much the same way that the FlashSystem V9000 is the all-Flash version of SVC. That is a reasonable analogy.
Jamie Thomas, IBM General Manager of Storage and Software Defined Environments
Jamie announced [IBM Elastic Storage], a new offering that is available as a software defined storage solution, based on IBM's General Parallel File System (GPFS) technology already deployed at 45,000 installations.
IBM Elastic Storage provides a global name view across data center locations. It can manage up to a Yotabyte of information, combining Flash, disk and tape resources. It supports OpenStack interfaces, Hadoop and standard POSIX file system conventions.
IBM Elastic Storage provides automated tiering to move data from different storage media types. Infrequently accessed files can be migrated to tape and automatically recalled back to disk when required. Unlike traditional storage, it allows you to smoothly grow or shrink your storage infrastructure without application disruption or outages.
IBM Elastic Storage software can run on a cluster of x86 and/or POWER-based servers, and can be used with internal disk, commodity storage, or advanced storage systems from IBM or other vendors.
IBM partnered with various clients in different industries in a special beta program. Jamie led a client panel to discuss their experiences with IBM Elastic Storage:
Alan Malek, Director of IT, Cypress Semiconductor.
"Total cycle time is key". Over the past 31 years, they bought whatever file storage was available. Now, with IBM Elastic Storage, the performance was very consistent for their engineering workloads with full load balancing.
Russell Schneider, Principal Storage Consultant, Jeskell.
Russell's company works with a lot of federal agencies, "Big Data has become Bigger Data". For example, research on Global Warming and Climate Change requires a large amount of storage across agencies.
In another example, when the tsunami hit Japan a few years ago, an agency here in the USA realized they had 14PB of data stored as a single copy in a data center at sea level less than a mile from the coast. They realized they needed to have a secondary copy, and an option to cache to a third location depending on regional disasters.
Matthew Richards, Products, OwnCloud.
For those not familiar with OwnCloud, it provides a Dropbox-like file sharing service, but in the Enterprise, with on-premise storage. It has been fully tested and certified with IBM Elastic Storage to provide a secure file sharing platform.
With IBM Elastic Storage, they were able to scale linearly up to 20,000 users, and are now testing 100,000 users. The need to have intelligent access to files at scale is what Matthew likes about IBM Elastic Storage.
Dr. Michael Factor, IBM Distinguished Engineer at IBM Research
Michael started out explaining there are three areas for storage: block, file and object. The fastest growing type of data is unstructured fixed content with associated metadata. This is ideal for object storage. Michael has been working with OpenStack Swift, an open source interface defined for object storage. He defined "storlets" as follows:
Storlets extend an object store by moving computation to the data -- filtering, transforming, analyzing -- instead of bringing data to the computation.
Storlets have been deployed on a variety of European Union research projects. For example, in partnership with Phillips, a pathology storlet can count the number of cancer cells in an image. By bringing the computation to the data, it eliminates having to transfer large amounts of data over the network.
Storlets can run on-premise and on IBM's SoftLayer IaaS cloud offering.
Bruce Hillsberg, IBM Director of Storage Systems at IBM Research
Bruce led another panel discussion, this time of IBM storage experts:
Vincent Hsu, IBM Fellow and CTO of Storage.
The problem is the isolation of data into "storage silos". Isolation causes problems in managing large amounts of data at scale, and costs more as storage is not fully utilized. IBM Elastic Storage brings everything together, eliminating storage silos.
Michael explained how IBM works with clients all over the world to ensure that storage solutions meet client requirements. For example, storlets can be used to use rich metadata to manage photographs, and display them based on GPS satellite location, or other content that makes it easier to manage these images.
IBM Elastic Storage will support OpenStack Cinder and Swift interfaces. IBM is a platinum sponsor of OpenStack foundation, and is now its second most prolific contributor, with hundreds of full-time employees working on this.
Tom Clark, IBM Distinguished Engineer, Chief Architect, Storage Software, Cloud & Smarter Infrastructure.
Storage Management is a critical piece of Software Defined Storage. This is done in three ways:
The use of analytics to optimize the deployment of storage, based on workload requirements. Storage admins set policies, and then IBM Elastic Storage analytics gather metrics and then optimize data placement and movement based on these policies. IBM Elastic Storage has 70 percent lower TCO that competitive offerings.
The focus on backup services. Backups are not just for data protection, but rather can be used to duplicate or replicate data for testing, for training, and for other purposes. IBM Elastic Storage is fully supported by IBM Tivoli Storage Manager.
Being able to support Hybrid Cloud environments, where some data can be on-premise, and other data off-premise. Storage Management challenges will need to deal with this possibility. IBM Elastic Storage is well positioned for this.
Carl Kraenzel, IBM Distinguished Engineer, Director of Watson Cloud Technology and Support.
Watson is ground-breaking technology, and IBM Elastic Storage technology was at the heart of the Watson that was first introduced in 2011.
To consider IBM Elastic Storage based on lower-cost and higher-scalability is not the full picture. Rather, this is an important platform for Cognitive Computing, which we are just at the tip of the iceberg in exploring. IT systems need to be aware of the context of what we are doing.
While the Grand Challenge demonstration on Jeopardy! was exciting, it is time we stop playing games and apply IBM Elastic Storage to business, to help with health care and medical research, and other problems in society. IBM has already deployed this at Anderson Cancer Center and Memorial Sloan Kettering Cancer Center, for example.
Tom Rosamilia provided closing remarks. IBM Elastic Storage is not just for new workloads in Cloud, Analytics, Mobile and Social (CAMS) but also traditional workloads as well. IBM Elastic Storage provides "data democracy" and allows for "better rested storage administrators" that make fewer mistakes.
Tom opened the floor for questions from the audience:
Q1. Data integrity, not just security but also quality? IBM Elastic Storage has end-to-end data integrity checking built-in.
Q2. How does IT transition from full control to auto-pilot? IBM allows you to tap into existing storage. This is not rip-and-replace. With storage virtualization, IBM hides the complexity that normally requires full control over specific assets.
Q3. Storage admins would rather have a root canal without Novocaine than move their data. What is IBM doing to offer automation to help storage admins move to this new infrastructure? IBM storage virtualization breaks that hard link between applications and specific storage devices. IBM Elastic Storage eliminates application downtime previously associated with data movement.
Tom Rosamilia assured the audience that IBM is fully committed to its storage portfolio. IBM Elastic Storage is not just about the profoundness of what IBM announced today, but also where IBM is investing in the future of storage.
Oh my, it is Tuesday again, and you know what that means? IBM Announcements!
This week, IBM announced its latest storage arrays in its IBM System Storage DS8000 series: the DS8880 models. Similar to the "Business Class" vs. "Enterprise Class" distinctions of the DS8870, IBM announced two new models, the DS8884 and the DS8886.
All of the new DS8880 models are based on the latest IBM POWER8 processors, and are noticeably thinner! These are now standard 19-inch wide, fitting nicely into standard IBM racks alongside most other standard 19-inch rack equipment.
The DC-UPS that used to be on the side are now at the bottom of each frame, taking up 8U of space. The High Performance Flash Enclosures (HPFE) that formerly were stored vertically above the DC-UPS will be stored horizontally with the rest of the HDD and SSD drives.
The DS8884 will have 6-core controllers, up to 256 GB Cache, 64 ports that can negotiate between 16Gbps and 8Gbps, up to 240 drives in a single-rack configuration or 768 drives in a three-frame configuration, and up to 120 flash cards in HPFEs. The performance of this one is equal or better to existing DS8870 systems.
The DS8886 will have 8-core, 16-core and 24-core controllers, offering up to three times the performance as the previous DS8870 models, with up to 2 TB of Cache, 128 ports, up to 1,536 drives across five frames, and up to 240 flash cards in HPFEs.
Field model conversion from DS8870 to DS8886 is available for existing clients with DS8870 Enterprise Configurations. This will let clients move their existing HDD, SSD, HPFE and Host Adapters over to the new DS8880 models.
In previous DS8000 models, clients would have one Hardware Management Console (HMC) inside the array, and an optional second HMC workstation somewhere else for high availability. While the second one was optional, it was always considered best practice to have it for redundancy sake. In the new DS8880 models, you can have both HMC in the array, and the Keyboard/Video/Monitor (KVM) can select between the two.
The new I/O enclosure pairs are four times faster, supporting six Device Adapters and two HPFE connections over PCIe Gen 3 network, the fastest available in the industry.
Lastly, IBM simplified the licensing of software features into three bundles, based on TB total capacity of Fixed Block (FB) LUNs and Count-Key-Data (CKD) volumes:
Base function License: Logical Configuration support for FB, Operating Environment License, Thin Provisioning, Easy Tier® automated sub-volume tiering, and I/O Priority Manager.
Copy Services License: FlashCopy®, Metro Mirror, Global Mirror, Metro/Global Mirror, z/Global Mirror (XRC), z/Global Mirror Resync, and Multi-Target PPRC.
z-Synergy Service License: Parallel Access Volumes (PAV), HyperPAV, FICON® attachment, High performance FICON (zHPF), and IBM z/OS® Distributed Data Backup (zDDB).
IBM also provided a "Product preview", announcing plans for a third member of the DS8880 family in 2016 that will be flash-optimized to provide an all-flash, higher performance storage system model.
Well, it's Tuesday, and that means IBM announcements!
IBM kicks EMC in the teeth with the announcement of System Storage Easy Tier, a new feature available at no additional charge on the DS8700 with the R5.1 level microcode. Barry Whyte introduces the concept in his [post this morning]. I will use SLAM (sub-LUN automatic movement) to refer generically to IBM Easy Tier and EMC FAST v2. EMC has yet to deliver FAST v2, and given that they just recently got full-LUN FAST v1 working a few months ago, it might be next year before you see EMC sub-LUN FAST v2.
Here are the key features of Easy Tier on the DS8700:
Sub-LUN Automatic Movement
IBM made it really easy to implement this on the DS8700. Today, you have "extent pools" that can be either SSD-only or HDD-only. With this new announcement, we introduce "mixed" SSD+HDD extent pools. The hottest extents are moved to SSD, and cooler extents are moved down to HDD. The support applies to both Fixed block architecture (FBA) LUNs as well as Count-Key-Data (CKD) volumes. In other words, an individual LUN or CKD volume can have some of its 1GB extents on SSD and other extents on FC or SATA disk.
Entire-LUN Manual Relocation
Entire-LUN Manual Relocation (ELMR, pronounced "Elmer"?) is similar to what EMC offers now with FAST v1. With this feature, you can now relocate an entire LUN non-disruptively from any extent pool to any other extent pool. You can relocate LUNs from an SSD-only or HDD-only pool over to a new Easy Tier-managed "mixed" pool, or take a LUN out of Easy Tier management by moving it to an SSD-only or HDD-only pool. Of course, this support also applies to both Fixed block architecture (FBA) LUNs as well as Count-Key-Data (CKD) volumes.
This feature also can be used to relocate LUNs and CKD volumes from FC to SATA pools, from RAID-10 to RAID-5 pools, and so on.
What if you already have SSD-only and HDD-only pools and want to use Easy Tier? You can now merge pools to create a "mixed" pool.
Before this announcement, you had to buy 16 solid-state drives at a time, called Mega-packs. Now, you can choose to buy just 8 SSD at a time, called Mini-packs. It turns out that just moving as little as 10 percent of your data from Fibre Channel disk over to Solid-State with Easy Tier can result in up to 300 to 400 percent performance improvement. IBM plans to publish formal SPC-1 benchmark results using Easy Tier-managed mixed extent pool in a few weeks.
Storage Tier Advisor Tool (STAT)
Don't have SSD yet, or not sure how awesome Easy Tier will be for your data center? The IBM Storage Tier Advisor Tool will analyze your extents and estimate how much benefit you will derive if you implement Easy Tier with various amounts of SSD. Those clients with R5.1 microcode on their DS8700 can download from the [DS8700 FTP site].
It's Tuesday, and you know what that means? IBM Announcements! This week I am in beautiful Orlando, Florida for the [IBM Systems Technical University] conference.
This week, IBM announced its latest tape offerings for the seventh generation of Linear Tape Open (LTO-7), providing huge gains in performance and capacity.
For capacity, the new LTO-7 cartridges can hold up to 6TB native capacity, or 15TB effective capacity with 2.5x compression that for typical data. That is 2.4x larger than the 2.5TB catridges available with LTO-6. Performance is also nearly doubled, with a native throughput of 315 MB/sec, or effective 780 MB/sec effective capacity with 2.5x compression. The LTO consortium, of which IBM is a founding member, has published the roadmap for LTO generations to LTO-8, LTO-9 and LTO-10.
IBM will offer both half-height and full-height LTO-7 tape drives. All the features you love from LTO-6 like WORM, partitioning and Encryption carry forward. These drives will be supported on a variety of distributed operating systems, including Linux on z System mainframes, and the IBM i platform on POWER Systems.
The Linear Tape File System (LTFS) can be used to treat LTO-7 cartridges in much the same way as Compact Discs or USB memory sticks, allowing one person to create conent on an LTO-7 tape cartridge, and pass that cartridge to the next employee, or to another company. LTFS is also the basis for IBM Spectrum Archive that allows tape data to be part of a global namespace with IBM Spectrum Scale.
LTO-7 will be supported on the TS2900 auto-loader, as well as all of IBM's tape libraries: TS3100, TS3200, TS3310, TS3500 and TS4500. You can connect up to 15 TS3500 tape libraries together with shuttle connectors, for a maximum capacity of 2,700 drives serving 300,000 cartridges, for a maximum capacity of 1.8 Exabytes of data in a single system environment.
In addition to LTO-7 support, the IBM TS4500 tape library was also enchanced. You can now grow it up to 18 frames, and have up to 128 drives serving 23,170 cartridges, for a maximum capacity of 139 PB of data. You can now also intermix LTO and 3592 frames in the same TS4500 tape library.
For comptability, LTO-7 drives can read existing LTO-5 and LTO-6 tape cartridges, and can write to LTO-6 media, to help clients with transition.
Well, it's Tuesday again, and you know what that means? IBM Announcements!
IBM Cloud Object Storage Gen2
Today, I want to look at a recent announcement around IBM Cloud Object Storage. On May 14th, IBM announced the [IBM Cloud Object Storage Gen2] hardware offerings, with a planned General Availability of June 7th so the timing is perfect to look at them. This announcement has benefits around performance, capacity and cost for the platform.
This enhancement to the platform takes the best of the current Cloud Object Storage architecture and extends it to allow for newer technologies, components, and approaches. These modifications incorporate new features, functionalities, and capabilities in an easily manageable manner. The same Cloud Object Storage software runs the same on both existing and new generation hardware. Clients can intermix past and present generations of hardware in the same storage pool and cluster.
As a part of this announcement, the IBM Cloud Object Storage Gen2 hardware brings with it a new COS Manager (Model M10), a new Accessor node (model A10) and a new SliceStor Controller Node (Model C10) which are all provided using the same physical 1U server that can be configured to suit as fit for purpose.
The Gen2 hardware leverages the latest Intel Xeon processors, new SAS controllers, and more options around high speed memory RDIMMs. Interestingly, provides the ability to implement an architecture that has a higher capacity in fewer rack units (RUs).
Previously, the SliceStor node was a single server with both controller and internal storage capacity. Now, a SliceStor is a new controller node, with externally-attached disk enclosures. This new approach is more elegant, in that the new server node becomes a common building block and now there are options around the disk enclosure. The disk enclosure options, small, medium and large, are listed in the table below to highlights the differences in capacity, density and drive options.

Node raw capacity (min/max TB)
The combination of the new architecture with industry standard components results in an initial system that achieves up to 15% more GETs and PUTs per second as the previous generation of hardware.
The new Cloud Object Storage Gen2 hardware can also reduce CAPEX expenditures on new hardware models up to 25%-50% compared to the prior generation.
