Well, it's Tuesday again, but this time, today we had our third big storage launch of 2009! A lot got announced today as part of IBM's big "Dynamic Infrastructure" marketing campaign. I will just focus on the
disk-related announcements today:
IBM System Storage DS8700
IBM adds a new model to its DS8000 series with the
[IBM System Storage DS8700]. Earlier this month, fellow blogger and arch-nemesis Barry Burke from EMC posted [R.I.P DS8300] on this mistaken assumption that the new DS8700 meant that DS8300 was going away, or that anyone who bought a DS8300 recently would be out of luck. Obviously, I could not respond until today's announcement, as the last thing I want to do is lose my job disclosing confidential information. BarryB is wrong on both counts:
IBM will continue to sell the DS8100 and DS8300, in addition to the new DS8700.
Clients can upgrade their existing DS8100 or DS8300 systems to DS8700.
BarryB's latest post [What's In a Name - DS8700] is fair game, given all the fun and ridicule everyone had at his expense over EMC's "V-Max" name.
So the DS8700 is new hardware with only 4 percent new software. On the hardware side, it uses faster POWER6 processors instead of POWER5+, has faster PCI-e buses instead of the RIO-G loops, and faster four-port device adapters (DAs) for added bandwidth between cache and drives. The DS8700 can be ordered as a single-frame dual 2-way that supports up to 128 drives and 128GB of cache, or as a dual 4-way, consisting of one primary frame, and up to four expansion frames, with up to 384GB of cache and 1024 drives.
Not mentioned explicitly in the announcements were the things the DS8700 does not support:
ESCON attachment - Now that FICON is well-established for the mainframe market, there is no need to support the slower, bulkier ESCON options. This greatly reduced testing effort. The 2-way DS8700 can support up to 16 four-port FICON/FCP host adapters, and the 4-way can support up to 32 host adapters, for a maximum of 128 ports. The FICON/FCP host adapter ports can auto-negotiate between 4Gbps, 2Gbps and 1Gbps as needed.
LPAR mode - When IBM and HDS introduced LPAR mode back in 2004, it sounded like a great idea the engineers came up with. Most other major vendors followed our lead to offer similar "partitioning". However, it turned out to be what we call in the storage biz a "selling apple" not a "buying apple". In other words, something the salesman can offer as a differentiating feature, but that few clients actually use. It turned out that supporting both LPAR and non-LPAR modes merely doubled the testing effort, so IBM got rid of it for the DS8700.
Update: I have been reminded that both IBM and HDS delivered LPAR mode within a month of each other back in 2004, so it was wrong for me to imply that HDS followed IBM's lead when obviously development happened in both companies for the most part concurrently prior to that. EMC was late to the "partition" party, but who's keeping track?
Initial performance tests show up to 50 percent improvement for random workloads, and up to 150 percent improvement for sequential workloads, and up to 60 percent improvement in background data movement for FlashCopy functions. The results varied slightly between Fixed Block (FB) LUNs and Count-Key-Data (CKD) volumes, and I hope to see some SPC-1 and SPC-2 benchmark numbers published soon.
The DS8700 is compatible for Metro Mirror, Global Mirror, and Metro/Global Mirror with the rest of the DS8000 series, as well as the ESS model 750, ESS model 800 and DS6000 series.
New 600GB FC and FDE drives
IBM now offers [600GB drives] for the DS4700 and DS5020 disk systems, as well as the EXP520 and EXP810 expansion drawers. In each case, we are able to pack up to 16 drives into a 3U enclosure.
Personally, I think the DS5020 should have been given a DS4xxx designation, as it resembles the DS4700
more than the other models of the DS5000 series. Back in 2006-2007, I was the marketing strategist for IBM System Storage product line, and part of my job involved all of the meetings to name or rename products. Mostly I gave reasons why products should NOT be renamed, and why it was important to name the products correctly at the beginning.
IBM System Storage SAN Volume Controller hardware and software
Fellow IBM master inventory Barry Whyte has been covering the latest on the [SVC 2145-CF8 hardware]. IBM put out a press release last week on this, and today is the formal announcement with prices and details. Barry's latest post
[SVC CF8 hardware and SSD in depth] covers just part of the entire
The other part of the announcement was the [SVC 5.1 software] which can be loaded
on earlier SVC models 8F2, 8F4, and 8G4 to gain better performance and functionality.
To avoid confusion on what is hardware machine type/model (2145-CF8 or 2145-8A4) and what is software program (5639-VC5 or 5639-VW2), IBM has introduced two new [Solution Offering Identifiers]:
5465-028 Standard SAN Volume Controller
5465-029 Entry Edition SAN Volume Controller
The latter is designed for smaller deployments, supports only a single SVC node-pair managing up to
150 disk drives, available in Raven Black or Flamingo Pink.
EXN3000 and EXP5060 Expansion Drawers
IBM offers the [EXN3000 for the IBM N series]. These expansion drawers can pack 24 drives in a 4U enclosure. The drives can either be all-SAS, or all-SATA, supporting 300GB, 450GB, 500GB and 1TB size capacity drives.
The [EXP5060 for the IBM DS5000 series] is a high-density expansion drawer that can pack up to 60 drives into a 4U enclosure. A DS5100 or DS5300
can handle up to eight of these expansion drawers, for a total of 480 drives.
Pre-installed with Tivoli Storage Productivity Center Basic Edition. Basic Edition can be upgraded with license keys to support Data, Disk and Standard Edition to extend support and functionality to report and manage XIV, N series, and non-IBM disk systems.
Pre-installed with Tivoli Key Lifecycle Manager (TKLM). This can be used to manage the Full Disk Encryption (FDE) encryption-capable disk drives in the DS8000 and DS5000, as well as LTO and TS1100 series tape drives.
IBM Tivoli Storage FlashCopy Manager v2.1
The [IBM Tivoli Storage FlashCopy Manager V2.1] replaces two products in one. IBM used
to offer IBM Tivoli Storage Manager for Copy Services (TSM for CS) that protected Windows application data, and IBM Tivoli Storage Manager for Advanced Copy Services (TSM for ACS) that protected AIX application data.
The new product has some excellent advantages. FlashCopy Manager offers application-aware backup of LUNs containing SAP, Oracle, DB2, SQL server and Microsoft Exchange data. It can support IBM DS8000, SVC and XIV point-in-time copy functions, as well as the Volume Shadow Copy Services (VSS) interfaces of the IBM DS5000, DS4000 and DS3000 series disk systems. It is priced by the amount of TB you copy, not on the speed or number of CPU processors inside the server.
Don't let the name fool you. IBM FlashCopy Manager does not require that you use Tivoli Storage Manager (TSM) as your backup product. You can run IBM FlashCopy Manager on its own, and it will manage your FlashCopy target versions on disk, and these can be backed up to tape or another disk using any backup product. However, if you are lucky enough to also be using TSM, then there is optional integration that allows TSM to manage the target copies, move them to tape, inventory them in its DB2 database, and provide complete reporting.
Yup, that's a lot to announce in one day. And this was just the disk-related portion of the launch!
Continuing my coverage of last week's Data Center Conference 2009, held Dec 1-4 in Las Vegas, I attended an interesting session related to the battles between Linux, UNIX, Windows and other operating systems. Of course, it is no longer between general purpose operating systems, there are also thin appliances and "Meta OS" such as cloud or Real Time Infrastructure (RTI).
One big development is "context awareness". For the most part, Operating Systems assume they are one-to-one with the hardware they are running on, and Hypervisors like PowerVM, VMware, Xen and Hyper-V have worked by giving OS guests the appearance that this is the case. However, there is growing technology for OS guests to be "aware" they are running as guests, and to be aware of other guests running on the same Hypervisor.
The analyst divided up Operating Systems into three categories:
Operating systems that are typically used to support other OS by offering Web support or other infrastructure. Linux on POWER was an example given.
DBMS/Industry Vertical Applications
Operating systems that are strong for Data Base Management Systems (DBMS) and vertical industry applications. z/OS, AIX, HP-UX, HP NonStop, HP OpenVMS were given as examples.
General Purpose for a variety of applications
Operating systems that can run a range of applications, from Web/Infrastructure, DBMS/Vertical Apps, to others. Windows, Linux x86 and Solaris were offered as examples.
The analyst indicated that what really drove the acceptance or decline of Operating Systems were the applications available. When Software Development firms must choose which OS to support, they typically have to evaluate the different categories of marketplace acceptance:
For developing new applications: Windows-x86 and Linux-x86 are must-haves now
Declining but still valid are UNIX-RISC and UNIX-Itanium platforms
Viable niche are Non-x86 Windows (such as Windows-Itanium) and non-x86 Linux (Linux on POWER, Linux on System z)
Entrenched Legacy including z/OS and IBM i (formerly known as i5/OS or OS/400)
For the UNIX world, there is a three-legged stool. If any leg breaks, the entire system falls apart.
The CPU architecture: Itanium, SPARC and POWER based chipsets
Operating System: AIX, HP-UX and Solaris
Software stacks: SAP, Oracle, etc.
Of these, the analyst consider IBM POWER running AIX to be the safest investment. For those who prefer HP Integrity, consider waiting until "Tukwilla" codename project which will introduce new Itanium chipset in 2Q2010. For Sun SPARC, the European Union (EU) delay could impact user confidence in this platform. The future of SPARC remains now in the hands of Fujitsu and Oracle.
What platform will the audience invest in most over the next 5 years?
45 percent Windows
14 percent UNIX
37 percent Linux
4 percent z/OS
A survey of the audience about current comfort level of Solaris:
10 percent: still consider Solaris to be Strategic for their data center operations and will continue to use it
25 percent: will continue to use Solaris, but in more of a tactical way on a case-by-case basis
30 percent: have already begun migrating away
35 percent: Do not run Solaris
The analyst mentioned Microsoft's upcoming Windows Server 2008 R2, which will run only on 64-bit hardware but support both 32-bit and 64-bit applications. It will provide scalability up to 256 processor cores. Microsoft wants Windows to get into the High Performance Computing (HPC) marketplace, but this is currently dominated by Linux and AIX. The analyst's advice to Microsoft: System Center should manage both Windows and Linux.
Has Linux lost its popularity? The analyst indicated that companies are still running mission critical applications on non-Linux platforms, primarily z/OS, Solaris and Windows. What does help Linux are old UNIX Legacy applications, the existence of OpenSolaris x86, Oracle's Enterprise Linux, VMware and Hyper-V support for Linux, Linux on System z mainframe, and other legacy operating systems that are growing obsolete. One issue cited with Linux is scalability. Performance on systems with more than 32 processor cores is unpredictable. More mature operating systems like z/OS and AIX have stronger support for high-core environments.
A survey of the audience of which Linux or UNIX OS were most strategic to their operations resulted in the following weighted scores:
140 points: Red Hat Linux
71 points: AIX
80 points: Solaris
40 points: HP-UX
41 points: Novell SUSE Linux
19 points: Oracle Enterprise Linux
29 points: Other
The analyst wrapped up with an incredibly useful chart that summarizes the key reasons companies migrate from one OS platform to another:
Reduce Costs, Adopt HPC
DBMS, Complex projects
Availability of Admin Skills
Performance, Mission Critical Applications
Availability of Apps, leave incumbent UNIX server vendor
Consolidation, Reduce Costs
Certainly, all three types of operating system have a place, but there are definite trends and shifts in this marketspace.
"With Cisco Systems, EMC, and VMware teaming up to sell integrated IT stacks, Oracle buying Sun Microsystems to create its own integrated stacks, and IBM having sold integrated legacy system stacks and rolling in profits from them for decades, it was only a matter of time before other big IT players paired off."
Once again we are reminded that IBM, as an IT "supermarket", is able to deliver integrated software/server/storage solutions, and our competitors are scrambling to form their own alliances to be "more like IBM." This week, IBM announced new ordering options for storage software with System x servers, including BladeCenter blade servers and IntelliStation workstations. Here's a quick recap:
IBM Tivoli Storage Manager FastBack v6.1 supports both Windows and Linux! FastBack is a data protection solution for ROBO (Remote Office, Branch Office) locations. It can protect Microsoft Exchange, Lotus Domino, DB2, Oracle applications. FastBack can provide full volume-level recovery, as well as individual file recovery, and in some cases Bare Machine Recovery. FastBack v6.1 can be run stand-alone, or integrated with a full IBM Tivoli Storage Manager (TSM) unified recovery management solution.
FlashCopy Manager v2.1
FlashCopy Manager uses point-in-time copy capabilities, such as SnapShot or FlashCopy, to protect application data using an application-aware approach for Microsoft Exchange, Microsoft SQL server, DB2, Oracle, and SAP. It can be used with IBM SAN Volume Controller (SVC), DS8000 series, DS5000 series, DS4000 series, DS3000 series, and XIV storage systems. When applicable, FlashCopy manager coordinates its work with Microsoft's Volume Shadow Copy Services (VSS) interface. FlashCopy Manager can provide data protection using just point-in-time disk-resident copies, or can be integrated with a full IBM Tivoli Storage Manager (TSM) unified recovery management solution to move backup images to external storage pools, such as low-cost, energy-efficient tape cartridges.
General Parallel File System (GPFS) v3.3 Multiplatform
GPFS can support AIX, Linux, and Windows! Version 3.3 adds support for Windows 2008 Server on 64-bit chipset architectures from AMD and Intel. Now you can have a common GPFS cluster with AIX, Linux and Windows servers all sharing and accessing the same files. A GPFS cluster can have up to 256 file systems. Each of these file systems can be up to 1 billion files, up to 1PB of data, and can have up to 256 snapshots. GPFS can be used stand-alone, or integrated with a full IBM Tivoli Storage Manager (TSM) unified recovery management solution with parallel backup streams.
For full details on these new ordering options, see the IBM [Press Release].
Continuing my coverage of the IBM Dynamic Infrastructure Executive Summit at the Fairmont Resort in Scottsdale, Arizona, we had a day full main-tent sessions. Here is a quick recap of the sessions presented in the morning.
Leadership and Innovation on a Smarter Planet
Todd Kirtley, IBM General Manager of the western United States, kicked off the day. He explained that we are now entering the Decade of Smart: smarter healthcare, smarter energy, smarter traffic systems, and smarter cities, to name a few. One of those smarter cities is Dubuque, Iowa, nicknamed the Masterpiece of the Mississippi river. Mayor Roy Boul of Dubuque spoke next on his testimonial on working with IBM. I have never been to Dubuque, but it looks and sounds like a fun place to visit. Here is the [press release] and a two-minute [video].
Smarter Systems for a Smarter Planet
Tom Rosamillia, IBM General Manager of the System z mainframe platform, presented on smarter systems. IBM is intentionally designing integrated systems to redefine performance and deliver the highest possible value for the least amount of resource. The five key focus areas were:
Enabling massive scale
Organizing vast amounts of data
Turning information into insight
Increasing business agility
Managing risk, security and compliance
The Future of Systems
Ambuj Goyal, IBM General Manager of Development and Manufacturing, presented the future of systems. For example, reading 10 million electricity meters monthly is only 120 million transactions per year, but reading them daily is 3.65 billion, and reading them every 15 minutes will result in over 350 billion transactions per year. What would it take to handle this? Beyond just faster speeds and feeds, beyond consolidation through virtualization and multi-core systems, beyond pre-configured fit-for-purpose appliances, there will be a new level for integrated systems. Imagine a highly dense integration with over 3000 processors per frame, over 400 Petabytes (PB) of storage, and 1.3 PB/sec bandwidth. Integrating software, servers and storage will make this big jump in value possible.
POWERing your Planet
Ross Mauri, IBM General Manager of Power Systems, presented the latest POWER7 processor server product line. The IBM POWER-based servers can run any mix of AIX, Linux and IBM i (formerly i5/OS) operating system images. Compared to the previous POWER6 generation, POWER7 are four times more energy efficient, twice the performance, at about the same price. For example, an 8-socket p780 with 64 cores (eight per socket) and 256 threads (4 threads per core) had a record-breaking 37,000 SAP users in a standard SD 2-tier benchmark, beating out 32-socket and 64-socket M9000 SPARC systems from Oracle/Sun and 8-socket Nehalem-EX Fujitsu 1800E systems. See the [SAP benchmark results] for full details. With more TPC-C performance per core, the POWER7 is 4.6 times faster than HP Itanium and 7.5 times faster than Oracle Sun T5440.
This performance can be combined with incredible scalability. IBM's PowerVM outperforms VMware by 65 percent and provides features like "Live Partition Mobility" that is similar to VMware's VMotion capability. IBM's PureScale allows DB2 to scale out across 128 POWER servers, beating out Oracle RAC clusters.
The final speaker in the morning was Greg Lotko, IBM Vice President of Information Management Warehouse solutions. Analytics are required to gain greater insight from information, and this can result in better business outcomes. The [IBM Global CFO Study 2010] shows that companies that invest in business insight consistently outperform all other enterprises, with 33 percent more revenue growth, 32 percent more return on invested (ROI) capital, and 12 times more earnings (EBITDA). Business Analytics is more than just traditional business intelligence (BI). It tries to answer three critical questions for decision makers:
What is happening?
Why is it happening?
What is likely to happen in the future?
The IBM Smart Analytics System is a pre-configured integrated system appliance that combines text analytics, data mining and OLAP cubing software on a powerful data warehouse platform. It comes in three flavors: Model 5600 is based on System x servers, Model 7600 based on POWER7 servers, and Model 9600 on System z mainframe servers.
IBM has over 6000 business analytics and optimization consultants to help clients with their deployments.
While this might appear as "Death by Powerpoint", I think the panel of presenters did a good job providing real examples to emphasize their key points.
Well, it feels like Tuesday and you know what that means... "IBM Announcement Day!" Actually, today is Wednesday, but since Monday was Memorial Day holiday here in the USA, my week is day-shifted. Yesterday, IBM announced its latest IBM FlashCopy Manager v2.2 release. Fellow blogger, Del Hoobler (IBM) has also posted something on this out atthe [Tivoli Storage Blog].
IBM FlashCopy Manager replaces two previous products. One was called Tivoli Storage Manager for Copy Services, the other was called Tivoli Storage Manager for Advanced Copy Services. To say people were confused between these two was an understatement, the first was for Windows, and the second was for UNIX and Linux operating systems. The solution? A new product that replaces both of these former products to support Windows, UNIX and Linux! Thus, IBM FlashCopy Manager was born. I introduced this product back in 2009 in my post [New DS8700 and other announcements].
IBM Tivoli Storage FlashCopy Manager provides what most people with "N series SnapManager envy" are looking for: application-aware point-in-time copies. This product takes advantage of the underlying point-in-time interfaces available on various disk storage systems:
FlashCopy on the DS8000 and SAN Volume Controller (SVC)
Snapshot on the XIV storage system
Volume Shadow Copy Services (VSS) interface on the DS3000, DS4000, DS5000 and non-IBM gear that supports this Microsoft Windows protocol
For Windows, IBM FlashCopy Manager can coordinate the backup of Microsoft Exchange and SQL Server. The new version 2.2 adds support for Exchange 2010 and SQL Server 2008 R2. This includes the ability to recover an individual mailbox or mail item from an Exchange backup. The data can be recovered directly to an Exchange server, or to a PST file.
For UNIX and Linux, IBM FlashCopy Manager can coordinate the backup of DB2, SAP and Oracle databases. Version 2.2 adds support specific Linux and Solaris operating systems, and provides a new capability for database cloning. Basically, database cloning restores a database under a new name with all the appropriate changes to allow its use for other purposes, like development, test or education training. A new "fcmcli" command line interface allows IBM FlashCopy Manager to be used for custom applications or file systems.
A common misperception is that IBM FlashCopy Manager requires IBM Tivoli Storage Manager backup software to function. That is not true. You have two options:
In Stand-alone mode, it's just you, the application, IBM FlashCopy Manager and your disk system. IBM FlashCopy Manager coordinates the point-in-time copies, maintains the correct number of versions, and allows you to backup and restore directly disk-to-disk.
Unified Recovery Management with Tivoli Storage Manager
Of course, the risk with relying only on point-in-time copies is that in most cases, they are on the same disk system as the original data. The exception being virtual disks from the SAN Volume Controller. IBM FlashCopy Manager can be combined with IBM Tivoli Storage Manager so that the point-in-time copies can be copied off to a local or remote TSM server, so that if the disk system that contains both the source and the point-in-time copies fails, you have a backup copy from TSM. In this approach, you can still restore from the point-in-time copies, but you can also restore from the TSM backups as well.
IBM FlashCopy Manager is an excellent platform to connect application-aware fucntionality with hardware-based copy services.
