Well, it's Tuesday again, and you know what that means? IBM Announcements!
Everyone is getting ready for next week's "Think 2018" event, so these might get missed under all the excitement.
IBM Spectrum Archive Enterprise Edition V1.2.6
IBM [Spectrum Archive] Enterprise Edition supports Linear Tape File System (LTFS) cartridges as part of a larger IBM Spectrum Scale deployment. Version 1.2.6 provides features to help transition from old technology to new technology, at the library, drive and cartridge level. It also adds support for "Little Endian" mode for IBM Power servers.
Tape library replacement procedure
Tape intermixing in pool for technology upgrade
Support for LTO 8 Media on LTO 8 drives
Support for Power Systems in Little Endian (LE) mode
IBM Copy Services Manager [CSM] was formerly knows as Tivoli Storage Productivity Center for Replication. It manages the copy services like FlashCopy and remote mirroring for DS8000, Spectrum Virtualize family, and Spectrum Accelerate family products. Version 6.2.2 adds some nice features:
Support for scheduled tasks against Copy Services Manager sessions
Support to create DS8000 system diagnostics from the Copy Services Manager GUI and CLI for issue resolution
New SNMP event and email notifications for any detected path failures
Ability to enable embedded Easy Tier heat map transfer to support full Copy Services Manager session configuration, including practice volumes
Next week, I will not be in Las Vegas for Think 2018. If you won't be there either, you might consider watching some of the livestream videos at [www.ibm.com/events/think/watch] starting March 19, 2018.
Lots of changes in the latest releases of IBM Spectrum Protect and Spectrum Protect Plus, respectively. Enough perhaps to save for a future post. I will point out a few key changes that I think are quite significant:
Cloud-based protection for currently supported databases hosted on Amazon Web Services (AWS) including IBM Db2, Oracle, Microsoft SQL Server, and MongoDB databases
Tier from disk-based storage pools to tape. Tape is less expensive than disk-based SAN, NAS or object storage. This features moves older backup copies that are not likely to be recovered to lower cost storage.
Internationalization: User Interface (UI) translations for Spanish, French, Italian, Japanese, Brazilian Portuguese, German, and Chinese languages.
IBM's FlashSystem products are recognized by the industry as the "World's Fastest Storage™" Here are some of the enhancements:
FlashSystem 900 now supports Remote Code Load and Remote Code Update. This is a feature we have already for the IBM DS8000 Storage System, and it has been wildly popular, eliminating the need to send a human being from IBM to your data center to update your firmware.
VersaStack™ Cisco Validated Design (CVD) for IBM FlashSystem 9100. This provides a converged system, a single rack with the leading-edge x86 servers and switches from Cisco, with IBM FlashSystem 9100 all-flash arrays.
Well, it's Tuesday again, and you know what that means? IBM Announcements! This week IBM announced new and refreshed storage products.
On Feb 20, there will be a [Live Stream event] to watch the announcements online. The event is at Half Moon Bay in California, starting at 9:30am Pacific Standard Time (PST).
IBM decided to do things a bit differently for this launch. Instead of dozens of stodgy press releases, IBM has opted to complement with a series of blog posts, with [Storage innovation drives 21st century business] providing an overall recap.
(FTC Disclosure: I work for IBM. This blog post can be considered a "paid celebrity endorsement")
IBM Spectrum NAS
IBM Spectrum NAS is a new software-defined storage offering to address three specific market segments:
General purpose file serving and home directories
Native SMB protocol NAS for Microsoft Windows Applications
File serving for Virtualization Environments, such as VMware and Hyper-V
IBM Spectrum NAS is software that you can run on your x86 servers, either bare metal or as Virtual Machines. You start with four nodes, and can scale out to tens of machines as you grow.
IBM Spectrum NAS was written from scratch, not based on open source SAMBA software. It has already been deployed internally within IBM last year, and now is being productized. It is very compatible with the SMB2 and SMB3.1 protocol specifications, and supports the NFS3, NFS4 and NFS4.1 protocols as well.
As a scale-out solution, it is both more robust and scalable than a single Windows server, and less expensive to run than traditional dual-controller NAS filers.
IBM Spectrum Protect has been enhanced to detect ransomware attacks, and improved auditing to meet European Union's General Data Protection Regulation [GDPR] privacy legislation.
(If you are not in Europe, and feel this legislation does not apply, you may be sadly mistaken. This legislation may affect any company that shares information with EU companies, or has even a single client from the European Union. Think of it as this year's [Y2K crisis]. It hits globally on May 25, 2018.)
IBM Spectrum Plus offers snapshot support for both VMware and Hyper-V virtualization environments. The vSnap repository can now be replicated to remote facility for Business Continuity and Disaster Recovery (BC/DR). IBM Spectrum Plus is now also available as a Software-as-a-Service (SaaS) offering on IBM Cloud.
IBM Spectrum Virtualize is the software in SAN Volume Controller, FlashSystem V9000, and the Storwize V7000 and V5000 series. It is also available as software you can deploy on your own x86 servers, or in the IBM Cloud. Fellow IBM master inventor and blogger Barry Whyte has a great post on the details of Spectrum Virtualize v8.1.2 latest release, including [Data Reduction Pools].
Cohasset Associates has reviewed the IBM Cloud Object Storage (IBM COS) Compliance Enabled Vaults (CEV) capability and determined that this feature meets the U.S. Security Exchange Commission SEC 17a-4 requirement for non-erasable, non-rewriteable (NENR) tamperproof enforcement.
Some clients also refer to this as Immutability, Content Addressable Storage, or Write-Once Read-Many (WORM). Rather than invent new terminology, IBM opts to use Non-erasable, Non-rewriteable to match the standard language in the SEC 17a-4 legislation.
IBM COS is now also eligible for "Storage Utility" pricing. See my blog post [ IBM Announcements 2017 November] for details on how Storage Utility pricing is implemented.
More than 15 years ago, I was the chief architect for IBM Spectrum Control, which back then was called the IBM TotalStorage Productivity Center.
A subset of IBM Spectrum Control was needed for a variety of IBM storage products to support VMware in a consistent manner, so IBM made this available as the "Spectrum Control Base Edition", entitled at no additional charge. Last year, IBM also merged in storage enablement for containerized environments like Docker.
Since "IBM Spectrum Control Base Edition with Storage Enablement for containerized environments" is too long to say, IBM shortened this to "Spectrum Connect". In addition to VMware and Docker support, Spectrum Connect also supports Microsoft PowerShell and IBM Cloud Private.
If you have 11.6.2a microcode on your XIV Gen3, you can now perform Online Volume Migration (OLVM) to FlashSystem A9000 and A9000R systems running 12.2.1 release. This will help clients in their migration efforts.
Well, it's Tuesday again, and you know what that means? IBM Announcements!
(FTC Disclosure: I work for IBM. This blog post can be considered a "paid celebrity endorsement" of the IBM Z and IBM storage products mentioned below.)
DS8880 R8.3.3 Enhancements
Back in 2015, IBM [DS8880 models] of the DS8000 family. Sales drastically increased, in part because IBM re-designed the systems to be a standard 19-inch wide rack, rather than the 33-inch wide custom sizes used before. Many cloud service providers (CSP) and managed service providers (MSP) require 19-inch standard rack configurations.
To meet client requirements, the newest IBM mainframes, including Z14 model ZR1 and LinuxONE Rockhopper II, are now following the same 19-inch rack size!
IBM DS8880 models now have enhanced support for zHyperlink connections. Clients with existing 6-core DS8884/F or 8-core DS8886/F models can upgrade to add more cores for zHyperlink connectivity.
Cores per CEC
Maximum zHyperlink connections
The zHyperlink supports both 40-meter and 150-meter cables. This allows applications like DB2 to read data with substantially lower latency than traditional FICON attachment.
For IBM z/OS clients, the Transparent Cloud Tiering feature allows migration of data directly from DS8000 storage systems to the cloud. This eliminates migrating data through the IBM Z, consuming MIPS and FICON traffic, back out to a tape or virtual tape system. IBM now offers 10GbE cards for the DS8880, providing faster throughput than the existing 1GbE cards previously available.
IBM Spectrum Scale v5.0 for IBM Elastic Storage Server
IBM Spectrum Scale v5.0 was available as software last year, and now is available as a Software PID for Elastic Storage Server hardware.
The new version introduces per-drive editions for licensing: Data Access edition, and Data Management edition. Here are highlights of some of the features:
Enhancements to GUI usability, including managing file systems between ESS and non-ESS storage
Audit File Logging (Data Management Edition only) for Open, Close, Destroy (Delete), Rename, Unlink, Remove Directory, Extended Attributed change, Access Control List (ACL) change
Enhancements to Active File Management, providing WAN-caching for multi-site deployments
Independent KPMG certification will be done for Spectrum Scale v5.0 on ESS for the "Immutability" feature. Some people refer to this as WORM, Government Compliance, Tamperproof, or Non-Erasable, Non-Rewriteable (NENR) enforcement protection
Enhancements to Transparent Cloud Tiering, providing archive of less-active data to IBM Cloud Object Storage, IBM Cloud, or Amazon S3.
Certification for analytics on both x86 and POWER platforms: Hortonworks Data Platform (HDP) v2.6, and Ambari v2.5
Improved I/O performance for many small and large block size workloads simultaneously, including a 4 MB default block size with variable sub-block size based on block size choice
Spectrum Scale 5.0 is incorporated into "Elastic Storage Server Solution Release 5.3". It is unfortunate the numbering is different. Existing ESS clients can download this new ESS 5.3 code from IBM FixCentral today. Going forward, starting next week or so, new Elastic Storage Servers will ship with ESS solution release 5.3 pre-installed.
The TS4500 tape library supports both TS1100 and LTO tape drives.
This feature supports mixed media in a TS4500 tape library. If you are using Library-Managed Encryption (LME), then IBM Security Key Lifecycle Manager is required as the key manager with LTO drives and cartridges.
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.
Officially, the VVol concept was still just a "technology preview" in 2012, to be fleshed out over the next few years through extensive collaboration between VMware and all the major players: IBM, HP, Dell, NetApp and EMC.
In 2013 and 2014, IBM attended VMworld with live demonstrations of VVol support. VMware vSphere v6 was not yet available, but when it was, we assured them, IBM would be one of the first vendors with support!
To understand why VVol is such a game-changer, you have to understand a major problem with VMware version 4 and version 5, namely their Virtual Machine File System, or [VMFS].
Here is a picture to help illustrate:
On the left, we see that VMFS datastore is a set of LUNs from the storage admin perspective, and a set of VMDK and related files from the vCenter admin perspective.
If there was a storage-related problem, such as bandwidth performance or latency, how would the two admins communicate to perform troubleshooting? For many disk systems, it is not obvious which VMDK file sits on which LUN.
There are also a variety of hardware capabilities that work at the LUN level, such as snapshots, clones or remote distance mirroring, and this would apply to all the VMDK files in the data store across the set of LUNs, which may not be what you want.
There are two ways to address this in vSphere v4 and v5:
The first method is to have fewer VMDK files per datastore. By defining smaller datastores with just a few VMs associated with each, you can then have a closer mapping of VMDK files to datastore LUNs. Unfortunately, VMware ESXi has a 256 limit on the number of different datastores that can be attached, so this method has its own limitations.
The other method around this is "Raw Device Mapping" (RDM) which allowed Virtual Machines to be attached to specific LUNs. Some of the earlier restrictions and limitations for RDMs have since been relaxed over the releases, but your disk system still needs to expose the SCSI identifiers of each LUN to make this work, and additional setup is required if you plan to cluster two or more systems together, such as for a Microsoft Cluster Server (MSCS).
On the right side of the picture, using VMware v6, vCenter admins can now allocate VVols, which are mapped to specific "VVol Storage Containers" on specific storage systems. The storage admin knows exactly which VVol is in which container, so they can now communicate and collaborate on troubleshooting!
The vSphere ESXi host communicates to storage arrays via a new "virtual LUN id" called a "Protocol Endpoint". This is to allow FCP, iSCSI and FCoE traffic to flow correctly through SAN or LAN switches. For NFS, the Protocol Endpoint represents a "virtual mount point", so that traffic can be routed through LAN switches correctly.
Storage Policies can help determine which attributes or characteristics you want for your VVol. For example, you may want your VVol to be on a storage container that supports snapshots at the hardware level. The vCenter server can be aware of which storage arrays, and which storage containers in those arrays, through the VMware API for Storage Awareness, or VASA.
Different storage manufactures can implement their VASA provider in different ways. IBM has opted to have a single VASA provider for all of its supported devices, so as to provide consistent client experience. When you purchase any VVol-supported storage system from IBM, you are entitled to download the IBM VASA provider at no additional charge!
Initially, the IBM VASA provider will focus on IBM XIV Storage System, an ideal platform for your VVol needs. The XIV is a grid-based storage system, utilizing unique algorithms that give optimal data placement for every LUN or VVol created, and virtually guarantees there will be no hot spots. The XIV provides an impressive selection of Enterprise-class features, including snapshot, mirroring, thin provisioning, real-time compression, data-at-rest encryption, performance monitoring, multi-tenancy and data migration capabilities.
Let me give some real world examples from Paul Braren, an IBM XIV and FlashSystem Storage Technical Advisor from Connecticut, who has been working directly with clients over the past five years:
"Many of my customers have clearly said they really want the ability to have a granular snapshot that grabs a moment in time of just one VM, rather than all the VMs that happen to be on the same LUN. They also want to delete VMs, and have the storage array automatically present that newly available space. Even better, with VVol, these SAN related tasks appear to be executed nearly instantly, leaving behind those legacy shared VMFS datastore limitations and overhead.
The same benefits of VVol are evident when cloning or deploying VMs. Imagine being to create a Windows Server VM with a 400GB thick-provisioned drive in under 20 seconds. Well, you don't have to imagine it! I recorded video of this actually happening over at IBM's European Storage Competence Center, featured in this 8-minute video: [IBM XIV Storage System and VMware vSphere Virtual Volumes (VVol). An ideal combination!]"
-- Paul Braren
In addition to XIV, all of IBM's Spectrum Virtualize products also support VVolLs, including SAN Volume Controller, Storwize including the Storwize in VersaStack, and FLashSystem V9000.
I am not in San Francisco this week for VMworld, but lots of my IBM colleagues are, so please, stop by the IBM booth and tell them I sent you!
IBM Storage Architect supporting customers in Canada and the Caribbean
Well we certainly had a busy April 2nd, so I wanted to take a minute to touch on the announcement surrounding IBM Spectrum Virtualize for Public Cloud and its availability in Amazon Web Services (AWS).
For those of you who attended the [IBM Think 2019] conference this year and stopped by the IBM Systems area on the event floor, you saw a preview of this running. This week we announced planned availability in AWS. If you were watching the live simulcast from Rome, you saw the IBM Product Marketing Manager for Spectrum Storage show this as part of the live demo. If you missed the live simulcast, check out the [April 2 Simulcast replay].
With the announcement of Spectrum Virtualize for Public Cloud V8.3.0, clients now have the ability to run Spectrum Virtualize like they can run IBM Spectrum Scale on AWS. IBM Spectrum Virtualize for Public Cloud has been available on IBM Cloud since 2017, and this extends the number of Cloud Service Providers. To learn more see the [Implementation Guide for IBM Spectrum Virtualize for Public Cloud] redpaper.
Data mobility to or from public cloud. This means customers looking to leverage hybrid Multicloud data mobility for disaster recovery or workload migration on AWS and IBM Cloud.
Non-disruptive data migration to, from, and between clouds. Leveraging tools like Global Mirror, clients are able to replicate data, and workloads between on premise IBM Storwize, IBM SAN Volume Controller (SVC), VersaStack and IBM FlashSystem 9100 systems and off premise instances of IBM Spectrum Virtualize for Public Cloud in IBM Cloud and AWS.
Cyber-resiliency with "air-gapped" snapshot in public cloud. Leveraging the native tools to create snapshots of the workloads and place them in S3 object storage in the cloud.
IBM Spectrum Virtualize will be deployed in AWS EC2 instances and be able to virtualize EBS volumes to present the storage to host systems. This also means that clients will also be able to leverage IBM Easy Tier across those virtualized EBS volumes to make the most out of the capability of their environments while still managing the cost, just like in on-premise solutions today.
This naturally comes along with the consistent enterprise-class storage functionality and management that clients are use to working with the IBM Spectrum Virtualize family. As part of this announcement, clients will also soon see pre-tested blueprints that will help speed deployment with confidence.
Well it's Tuesday again, and you know what that means? IBM Announcements!
(FCC Disclosure: This official launch also includes October 6 announcements. In any case, the usual disclaimer applies: I currently work for IBM, and this blog post can be considered a "paid celebrity endorsement" of the IBM products mentioned below.)
IBM announced various updates to its Spectrum Storage product line. Here is a quick recap.
IBM Spectrum Virtualize 7.6
Spectrum Virtualize is the new name of the "storage hypervisor" code that resides in IBM SAN Volume Controller (SVC) and Storwize family products. When you buy an SVC, you will license Spectrum Virtualize software on it. It is NOT available separately as software-only that you can install on any other hardware. There are three major improvements:
Software-based Data-at-Rest Encryption
Earlier this year, IBM delivered data-at-rest encryption for the Storwize V7000 and V7000 Unified. This week, IBM extends this support to other storage hypervisors.
Since this feature is based on the Intel processor that supports the Advanced Encryption Standard New Instructions (AES-NI), it applies only to the newer hardware: SAN Volume Controller 2145-DH8, the Storwize V7000 Gen2, FlashSystem V9000, and VersaStack converged systems that contain these. You can run Spectrum Virtualize v7.6 on older hardware models, but the encryption feature will be disabled.
Basically, by taking advantage of AES-NI commands, IBM can now offer data-at-rest encryption on any virtualized flash or disk arrays, eliminating the need for special "Self-Encrypting Drives", or SED.
The encryption keys are kept on USB memory sticks, that you can either leave in the machine, or stash away in some vault or safe somewhere.
The other improvement is distributed RAID. Distributed RAID has been hugely popular on IBM XIV products, and has since found its way into the DCS3700, DCS3860 and Elastic Storage Server models.
With this new enhancement, storage admins can select "Distributed RAID-5" or "Distributed RAID-6" as alternate choices to traditional RAID ranks.
Why use it? All the drives are now active, eliminating idle spare drives that do nothing collecting dust and cobwebs waiting for an opportunity to spin up, and when they finally are used for a rebuild become a terrible bottleneck. Since all drives are reading and writing, the rebuild rate is an order of magnitude (5 to 10x) faster!
For those clients nervous about large 8TB drives and the number of days it would take to perform a traditional RAID rebuild, this should calm all of your fears.
This is one of those line-items that we have told clients that it was "just around the corner" and "coming soon, watch this space", and finally it is available. For clients using Stretched Cluster or HyperSwap across two buildings, best practices suggests keeping the quorum disk in a third building. This often met having to dedicate a single 2U disk system in a closet somewhere, with expensive Fibre Channel cables connecting to the other two buildings.
To address this, IBM now allows the quorum disk to be based on Internet Protocol (the IP portion of TCP/IP), which can be any bare-metal or virtual machine that is LAN or WAN attached. The "quorum disk" is just a little Java program. This can run on any cloud service provider as well, such as IBM SoftLayer, that both buildings have connectivity.
A minor improvement worth mentioning is that the IBM "Comprestimator" tool that estimates the capacity savings of Real-time Compression is now integrated into Spectrum Virtualize v7.6 command line interface (CLI), allowing you to run the tool on demand, as needed, on any virtual volume.
IBM Spectrum Scale v4.2
IBM plans to offer all of its solutions in any of three flavors: software-only that you can deploy on your own server hardware, pre-built system appliances, and cloud services on IBM SoftLayer, IBM Cloud Managed Services or third-party cloud providers. Spectrum Scale is the software-only flavor, and Elastic Storage Server and Storwize V7000 Unified are pre-built systems based on that software.
File and Object access
IBM published a "Redbook" on how to implement OpenStack Swift and Amazon S3 interfaces to an existing Spectrum Scale deployment. IBM supported it, but it was basically Do-it-Yourself DIY implementation. This has now been resolved, with full integration of OpenStack Swift and Amazon S3 object-protocol interfaces.
(For those unfamiliar with "Object storage", think of it like valet parking for your data. Before working for IBM, I was previously employed as a valet attendant, so I feel qualified to make this analogy.
If you park your car in a 10-story high parking structure, you have to remember where you parked to go find the car again. With valet parking, you hand over the keys to the valet attendant, the car gets parked, and you get a claim stub that you then use to get your car back. In the meantime, you don't know where your car is parked, and you don't care either!
Storing files in volume-level or file-level storage is like that 10-story high parking structure. You have to remember where you put it, which LUN or which sub-directory. With object storage, the system provides a "claim stub" in the form of an Universal Record Identifier, or URI, and simple HTTP commands like GET and POST can be used to upload and download the content.)
Policy-driven Compression and Quality of Service (QoS)
If you want to differentiate the levels of service provided by files and objects stored in your infrastructure, look no further. Simple SQL-like language is used to set up policies that are invoked when needed.
Hadoop Connector for File and Objects
The IBM Hadoop Connector allows Hadoop and Spark analytics applications to treat Spectrum Scale as a 100 percent compatible alternative to Hadoop File Systems (HDFS). Previously, this was only available for files, but now it has been extended to include objects as well.
Advanced Graphical User Interface (GUI)
Based on the award-winning GUI that has been used for IBM XIV, SVC, Storwize and various other members of the IBM System Storage family, IBM announces an HTML5-based web-browser GUI for configuring and managing Spectrum Scale and Elastic Storage Server (ESS).
Storwize V7000 Unified
The "file modules" that run IBM Spectrum Scale will get updated to R1.6 level, which supports SMB 3.0 and NFS 4.0 protocols. SMB support will now include both internal and externally-virtualized storage. You will also be able to use Active File Management to migrate to other Spectrum Scale implementations.
IBM Spectrum Control
As the former chief architect of IBM Tivoli Storage Productivity Center v1, I have been a big fan of the advancements and evolution of Spectrum Control. IBM offers three levels. The first level is "Basic Edition", entitled at no additional charge for IBM storage hardware clients. The second level is "Standard Edition" which offers configuration, provisioning and performance monitoring. The third level is "Advanced Edition", which includes advanced storage analytics, file-level reporting, storage tiering and data placement optimization.
You can imagine my skepticism when I was told that Spectrum Control was going to be enhanced to support Spectrum Scale. What could it offer? IBM Spectrum Scale already has built-in storage tiering and data placement optimization!
It turns out that having effective "management tools" was the #1 reason clients have stated were needed to implement and deploy Spectrum Scale. Since 1998, back when it was called General Parallel File System, or GPFS, the target market was High Performance Computing (HPC) familiar with Command Line Interfaces (CLI).
But IBM was to broaden the reach of IBM Spectrum Scale, to financial services, health care and life sciences, government and education, and a variety of other industries. They won't tolerate being limited to CLI interfaces.
For clients with multiple Spectrum Scale clusters, Spectrum Control can offer the following:
Visibility across the capacity utilization (file systems, pools, file sets, quotas) and cluster health across all Spectrum Scale clusters in the data center
Ability to specify alerts which are applied across all Spectrum Scale clusters, for things like relative or absolute free space in a file system, or inodes used, nodes going down, etc.
Understand the cross-cluster relationships established by remote cluster mounts, and seamlessly navigate between them
If external SAN storage is used, Spectrum Control shows the correlation between Spectrum Scale Network Shared Disks (NSD) and their corresponding SAN volumes, again with the ability to navigate between them; also it can provide performance monitoring for the volumes backing the NSD
Ability to monitor file capacity usage in the context of applications, by adding Spectrum Scale "file set containers" to application groups defined in Spectrum Control
Compare file system activity across Spectrum Scale clusters, with the ability to drill into file system and node performance charts
Support for object storage on Spectrum Scale, determine which object-enabled clusters are closest to running out of free space
While the basic built-in GUI is great for smaller deployments, if you have a dozen or more Spectrum Scale clusters, or have Spectrum Scale clusters intermixed with traditional block-level and NAS storage devices, then Spectrum Control is for you!
It used to take weeks to deploy the original versions of Tivoli Storage Productivity Center, but now, Spectrum Control is now offered in the cloud, and you can deploy it in as little as 30 minutes.
Want to check it out? You can explore Spectrum Control Storage Insights cloud service as a [Live Demo], or [Start your free trial]! The reporting capabilities of Spectrum Scale are identical between the on-premise version of Spectrum Control, and this cloud service offering.
Here's a great quote from a leading IT industry analyst:
"In multi-petabyte, multivendor installations, overall storage costs of ownership for use of IBM Spectrum Storage solutions averaged 73 percent less than EMC, and 61 percent less than Hitachi equivalents" -- Brian Jeffery, Managing Director, International Technology Group, Naples, FL
As IBM continues its transition from a hardware-oriented company founded over a century ago, manufacturing meat scales and cheese slicers, to one more focused on higher value-add software and services, the Spectrum Storage software family will play a critical role of this transformation!
Well it's Tuesday again, and you know what that means? IBM announcements!
Today, IBM announced a few things related to storage.
IBM Spectrum Copy Data Management
This new member of the IBM Spectrum Storage family helps manage all of those snapshot and FlashCopy images made to support DevOps, data protection, disaster recovery, and Hybrid Cloud computing environments.
The software automates the creation and catalog the copy data on existing storage infrastructure, such as snapshots, vaults, clones, and replicas. This can be especially useful with Oracle, Microsoft SQL server, and other databases that are often copied to support application development, testing, and data protection.
Initially, the following storage devices are supported:
IBM storage systems running IBM Spectrum Virtualize™ Software V7.3, and later, including IBM SAN Volume Controller, IBM Storwize®, and IBM FlashSystem® V9000
Storage systems running IBM Spectrum Accelerate™ 11.5.3, and later, including IBM FlashSystem A9000, A9000R, and IBM XIV® and the Supermicro Hyperconverged Appliance
IBM SKLM is IBM's lead offering for creating and managing encryption keys used by various Flash, Disk, Tape and SAN products.
This software release enhances the separation of duties for better alignment with regulatory requirements, simplifying the administrative access, LDAP integration, and device certificate TrustStore management. Device-group key import and export improves the flexibility in key management across multiple organizations.
For those using Hardware Security Modules [HSM], this software now offers HSM-based backup and restore of the encryption key database.
IBM is also enhancing its support of the Key Management Interoperability Protocol [KMIP], an industry standard to support encryption keys and the products that use them. This release now supports integration with any KMIP-compliant device from any vendor, including the introduction of KMIP Opaque and Suite B profiles.
IBM Storage Networking MDS 9000 24/10-port SAN Extension Module
The new MDS 9000 24/10-port SAN Extension Module is supported on MDS 9700 Series Multilayer SAN Fabric Directors. It supports 24 Fibre Channel Ports (auto-negotiating 2/4/8/10/16 Gbps), eight (1/10) GbE Fibre Channel over IP (FCIP) for long-distance replication, and two 40 GbE FCIP ports.
The modules support virtual SAN (VSAN), Hardware-based encryption to help secure sensitive traffic with Internet Protocol Security (IPsec), and hardware-based compression to dramatically enhance performance for both high-speed and low-speed links. This can help reduce costs for long-distance replication over expensive WAN infrastructure.
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.
