IBM October 2012 Enterprise Systems Announcements

TonyPearson Tags: ts7740 ts7720 ds8870 ibm xiv 2 Comments 7,695 Visits

Well it's Wednesday, and you know what that means... IBM Announcements.

(Normally, announcements are on Tuesdays, but we moved this one over to Wednesday to line up with our big launch event in Pinehurst, NC. )

A lot was announced today, so I decided to break it up into several separate posts. I will start with our Enterprise Systems: DS8870, TS7700 Release 3, and XIV Gen3.

Enterprise systems are the servers, storage and software at the core of an enterprise IT infrastructure. Enterprise systems enable a private cloud infrastructure at enterprise scale, with flexible service delivery models that provide dynamic efficiency for resource and workload management. They make sure critical data is always available across the enterprise, making it accessible in new ways so that actionable insights can be derived from advanced and operational analytics. They also provide ultimate security, ensuring the integrity of critical data while mitigating risk and providing assured compliance.

IBM System Storage DS8870® disk system

This new storage system is the next generation in IBM's DS8000 series, based on IBM's POWER7 chipset. Each CEC can have 2, 4, 8 or 16 cores. Like the DS8800, you can have a mix of 2.5-inch and 3.5-inch disk drives of different speeds and capacities, up to 1,536 drives in a four-frame configuration. The maximum cache is now 1TB usable. The combination of faster chipset and more cache can triple performance for some workloads!

All DS8870s ship standard with all Full Disk Encryption (FDE-capable) drives. The problem in the past was that people would buy DS8000 with non-FDE drives, and then later want to activate encryption, and discovered that they have to swap out their drives with those with the encryption chip built in. Now, all drives on the DS8870 will have the encryption chip. This also allows Easy Tier sub-volume automated tiering to move encrypted data between all media types. Flash optimization with DS8000 Easy Tier can improve performance up to 3 times with 3% of data on solid-state storage. Easy Tier is easy to deploy and runs automatically.
Support of the American National Standards Institute's (ANSI) T10 Data Integrity Field (DIF) standard. This is a feature that the mainframe has had for years, and is now being extended to distributed operating systems. The concept is simple. When sending data between server and storage, generate a checksum at the source, and then validate the checksum at the target. When you write a block of data, the server generates the checksum, and the DS8870 validates the checksum on arrival. When you read the data back, the DS8870 generates the checksum, and the server validates it on arrival. This ensures that data was not corrupted in between. There is a great write-up on IBM developerWorks: [End-to-end data protection using T10 standard data integrity field].
Energy Efficient. The DS8870 consumes less energy than its predecessor, the DS8800. For example, a fully-configured four-frame DS8870 with 1,536 disk drives consumes only 23.2kW, compared to the same number of drives in a DS8800 consumed 26.3 kW. By comparison, the DS8700 with five frames and 1,024 drives consumed 29.2kW.
RoHS 2012 compliant. RoHS stands for the [Restriction of Hazardous Substances]. This is a requirement to sell IT equipment in the European Community.
Support for new System z load balancing algorithm. System z Workload Manager now interacts with the DS8870 I/O Priority Manager to optimize designated Quality of Service (QoS) levels. We have also the fastest operational analytics solution with DB2 list Prefetch cache optimization with DS8870 High Performance FICON (zHPF) integration. This solution increases DB2 query performance up to 11 times with disk, and up to 60 times with solid-state drives (SSD). File scans are up to 30 percent faster using DS8870 zHPF support for sequential access methods (QSAM, BPAM, and BSAM).
VMware vStorage APIs for Array Integration (VAAI) support. Why should the IBM DS8800 series support VMware when IBM already offers great VMware support with SAN Volume Controller (SVC), Storwize V7000 and XIV storage sytsems? Good question. This was hotly debated between development and marketing. Several DS8000 customers have already added SVC to provide full VMware VAAI support. As a consultant, I am neither development nor marketing, but felt it necessary to weigh in on my opinion on this. The DS8000 is a consolidation platform. According to one analyst survey, 22 percent of companies run on a single disk platform, so for DS8000 to be the one, it needs to support VMware and exploit these special APIs.
Six Nines Availability. Critical enterprise systems need to deliver continuous data availability, or very close to it. IBM solutions can help deliver up to six “nines” of availability, or 99.9999 percent when combining DS8000 Metro Mirror and GDPS Hyperswap. That's less than 30 seconds of downtime per year.

To learn more about the IBM DS8000 series, read the [DS8000 Solution Brief].

IBM Virtualization Engine™ TS7700 Release 3

The TS7700 Release 3 represents a refresh to our existing virtual tape libraries. These are mainframe-only, offered in two models: TS7720 is a disk-only device, and the TS7740 is a blended disk-and-tape solution.

Industry standard hardware encryption. This applies to user data stored on the TS7700 system cache (disk), and for data transferred between TS7700 systems. This is especially important for regulations, like Payment Card Industry Data Security Standard (PCI-DSS). In previous models, the data would not be encrypted until it was moved off disk and written to tape. Now, it is encrypted the minute in lands on the disk cache, and stays encrypted as it is replicated from one TS7700 to another in the grid.
Up to 4 Million logical volume capacity. This is twice the previous support.
More physical capacity for TS7720 systems. The maximum capacity for the disk-only model is raised from 440TB to 620TB, representing a 40 percent increase.

My latest book "Inside System Storage: Volume V" is now available!

I have published my fifth volume in my "Inside System Storage" series! Currently, it is only available in Paperback. My editor, Susan Pollard, is hoping to have the eBook and Hardcover versions ready for Cyber Monday. The foreword was written by my Dr. Sondra Ashmore.

You can order this, and all my other books, in all formats, directly from my [Author Spotlight] page. The paperback will also be available soon from other online booksellers, search for ISBN 978-1-300-26223-7.

IBM XIV Storage System Gen3

The [XIV Gen3 was announced last July 2011]. Today we have some enhancements to this platform:

Improved Scalability. A new Multi-system Manager (MSM) server reduces the operational complexity for large and multi-site XIV deployments. Previously, admins connected directly to XIV boxes. If you had 10 admins logged in, then every XIV box was managing 10 admin conversations. The new MSM acts as a go-between. The admins connect to the MSM, and the MSM connects to the XIV boxes. The MSM polls and caches the status of each XIV, greatly increasing the number of XIV boxes that an admin can manage.
Enhanced User Interface. A new Multi-system Manager server reduces the operational complexity for large and multi-site XIV deployments. We also added support for IPsec and US. Government (USGv6) certification for admistering the XIV over IPv6 networks. The XIV Mobile Dashboard app for iPhone and iPad is spiffed up. Finally, the GUI has been internationalized and translated to the Japanese language.
Enhanced Integration for Cloud. For OpenStack, XIV now offers a Nova-volume driver which provides persistent storage to OpenStack compute nodes. The Nova task force is now looking to move storage into its own project called Cinder. For VMware, XIV has full support for Site Recovery Manager (SRM) v4.1 and v5.0 releases. XIV now also supports the Microsoft System Center Virtual Machine Manager, which can manage Hyper-V, VMware and Citrix XenServer hypervisors.
Smaller entry point. The original XIV supported 1TB and 2TB drives, with the smallest offering being 27TB usable. When IBM introduced the XIV Gen3, the two choices were 2TB and 3TB disk drives. Unfortunately, this meant that the initial entry model was now 55TB in size, and each additional module would be more expensive as well. IBM is now going to offer 1TB support for XIV Gen3 for a lower price point, these are actually 2TB drives with half the capacity turned off.

IBM Announcements for February 2012

Well, it's Tuesday again, and you know what that means! IBM Announcements! Typically, IBM System Storage has three to five major product launches per year. Making announcements every Tuesday would have been two frequent, and having one big announcement every two or three years would be too far apart. Worldwide combined revenues for storage hardware and software grew double digits last year, comparing full-year 2011 to the prior 2010 year, and I am sure that 2012 will also be a good year for IBM as well! This week we have announcements for both disk and tape, but since 2012 is the 60th Diamond Anniversary for tape, I will start with tape systems first.

TS1140 support for JA/JJ tape cartridges

The TS1140 enterprise tape drive was announced at the [Storage Innovation Executive Summit] last May. It supported a new E07 format on three different new tape cartridges. Models "JC" was 4.0TB standard re-writeable tapes, "JY" was 4.0TB WORM tapes, and "JK" were 500GB economy tapes that were less expensive, but offered faster random access.

Generally, IBM has adopted an N-2 read, N-1 write [backward compatibility]. This means that the TS1140 could read E05 and E06 formatted tapes on JB and JX media, and could write E06 format on JB and JX media. However, there are a lot of older JA and JJ media, especially as part of TS7740 environments, so IBM now supports TS1140 drives to read J1A formatted JA and JJ media. This is not just for TS7740 environments, any TS1140 in stand-alone or tape library configurations will support this as well.

TS7700 R2.1 enhancements

IBM is a leader in tape virtualization with or without physical tape as back-end media. There are two hardware models of the [IBM Virtualization Engine TS7700 family] for the IBM System z mainframe. These virtual libraries are referred to as "clusters" in IBM literature.

The TS7740 Virtual Tape Library supports putting virtual tape images on disk first, then move less-active data to physical tape, which I covered in my blog post [IBM Announcements - July 2007].
The TS7720 Virtual Tape Library supports a disk-only approach, which I covered in my blog post [IBM Mainframe Disk and Tape Announcements - October 2008].

A unique feature of the TS7700 series is support for a Grid configuration, which allows up to six different TS7700 clusters to be grouped into a single instance image. These clusters can be in local or remote locations, connected via WAN or LAN connections.

R2.1 is the latest software release of this successful IBM's TS7700 series.

True Sync Mode Copy. Before R2.1, the TS7700 offered "immediate mode copy". An application would write to a virtual tape, and when it was done with the tape and performed an unmount, the TS7700 would then replicate the tape contents to a secondary cluster on the grid. With True Sync Mode, data contents are replicated per implicit or explicit SYNC points. This is another IBM first in the IT tape industry.
Remote Mount Fail-over. When you have two or more TS7700 clusters in a grid configuration, you can do remote mounts. We've added fail-over multi-pathing up to four paths, so that if a link to a remote cluster is down, it will try one of the others instead.
Parallel Copies and Pre-Migration. On of my 19 patents is for the pre-migration feature for the IBM 3494 Virtual Tape Server (VTS) that carries forward into the TS7700, and is also used in the SONAS and Information Archive products. However, when the grid architecture was introduced, the engineers decided not to allow pre-migration and copies to secondary clusters to occur concurrently. Now these two operations can be done in parallel.
Merge two grids into one grid. Now that we can support up to six clusters into a single grid, we have people with 2-cluster and 3-cluster grids looking to merge them into one. Of course, all the logical and physical volume serials (VOLSER) must be unique!
Accelerate off JA/JJ Media. There are a lot of older JA and JJ media still in TS7700 libraries. This feature allows customers to speed up the transition to newer physical tape media.
Copy Export to E06 format on JB media. This one is clever, and I have to say I would have never thought about it. Let's say you have a TS7740 with TS1140 drives, but you want to export some virtual tapes to physical media to be sent to someone who only has a TS7740 connected with older TS1130 drives. These older drives can't read new JC media nor make sense of the E07 format. This feature will let you export to older JB media in E06 format so that it will be fully readable at the new location on the TS1130 drives.
Copy Export Merge service offering. Thanks to mergers and acquisitions, it is sometimes necessary to split off a portion of data from a TS7700 grid. In the past, IBM supported sending this export to a completely empty TS7700 library, but this new service offerings allows the export to be merged into an existing TS7700 that already contains data.

LTFS-SDE support for Mac OS X 10.7 Lion

How do people still not yet know about the Linear Tape File System [LTFS]? I mentioned this in my blogs back in 2010 in [April], [September], and [November]. Last year, LTFS was the [NAB Show Pick Hits Award] and an [Emmy] for revolutionizing the use of digital tape in Television broadcasting.

In layman's terms, the Single Drive Edition [LTFS-SDE] allows a tape cartridge to be treated like USB memory stick. It is supported on the LTO5 tape drives for systems running various levels of Windows, Linux and Mac OS X. Prior to this announcement, IBM supported Snow Leopard (10.5.6) and Leopard (10.6), and now supports Mac OS X 10.7 "Lion" release.

XIV Gen3 Solid-State Drives (SSD)

The [IBM XIV Gen3 storage system] now supports Solid State Drives! I thought I would provide some context from a historic perspective.

IBM first introduced Solid-State Drives (SSD) back in 2007 where it made sense the most, in [drive-for-drive replacements on blade servers in the IBM BladeCenter]. Blade servers typically only have a single drive, and SSD are both faster and use less energy on a drive-for-drive comparison, so this provided immediate benefit. Today, SSD are available on a variety of System x and POWER system servers.

In 2008, IBM rocked the world by being the first to reach [1 Million IOPS with Project Quicksilver]. This was an all-SSD configuration which many considered unrealistic (at the time), but it showed the potential for solid state drives.

In 2010, IBM announced [DS8700 Easy Tier with Sub-LUN automated tiering], and followed it up with similar support for [SVC 6.1 and Storwize V7000] that provides this enterprise-class functionality to midrange and externally-virtualized storage systems.

In 2011, IBM was able to [scan 10 billion files in 43 minutes] using the GPFS file system in support of Big Data analytics. This, of course, was done with Solid State Drives.

When the [XIV Gen3 was Announced - July 2011], each module included an 1.8-inch "SSD-Ready" slot in the back. IBM made a Statement of Direction that IBM would someday offer SSD drives to put in these slots. Today's announcement is that IBM has finalized the qualification process, so now XIV Gen3 clients can have 400GB of usable non-volatile SSD read cache added to each module. This SSD can be added to existing XIV Gen3 boxes in the field, or it can be factory-installed in new shipments. If you have a 15-module XIV, that's 6TB of additional read cache! This SSD is entirely managed by the XIV Gen3, so you won't have to spend weeks reading manuals or specifying configuration parameters.

My colleague Elisabeth Stahl covers this from a performance angle in her blog post [Performance in a Flash: New IBM XIV SSD Caching].

When you carve volumes on the XIV, you now have an option to enable or disable use of the SSD cache for each volume. Since XIV is being used in private and public cloud deployments, this offers the ability to offer premium performance at premium prices. The use of SSD is complementary to IBM XIV Quality of Service (QoS) performance levels, which are determined by host instead.

Well, that's the first major IBM System Storage launch of 2012. Let me know what you think in the comment section below.
