While some might be familiar with mashups that combine public Web 2.0 sources of information, enterprise mashups go one step further, integrating withthe "information infrastructure" of your data center. It's not just enough to deliver theright information to the right person at the right time, it has to bein the right format, in a manner that can be readily understood andacted upon. Enterprise mashups can help.
IBM hired independent analyst Enterprise Strategy Group[ESG] to validate the box, and run workload-specific benchmarks. I agreewith Chris, the results are impressive! The report includes results from Microsoft Exchange JetStresstool to provide insight into email performance, and another benchmark to simulate Web server IOPS.
Also, the published SPC-1 benchmark for the DS5300 puts it at about 29 percent improvement over the DS4800.Chris argues the DS5300 is similar in class to NetApp FAS3170, which IBM sells as the IBM System Storage N6070.
If you are interesting in either the DS5300 or N6070, contact your local IBM Business Partner or sales rep.
Well, it's Tuesday, and more IBM announcements were made today. Many of my colleagues are in Dallas, Texas for the[Storage Networking World conference], and hopefully I will get some feedback from them before the week is over.
Today, IBM made announcements for Storage Area Networking (SAN) gear and disk systems.
8 Gbps Longwave transceivers
IBM now offers 8 Gbps Longwave SFP transceivers on the[IBM System Storage SAN256B and SAN768B] directors, as well as the IBM System Storage SAN24B-4 Express, SAN40B-4, and SAN80B-4 switches (orderable as [machine type models] or [partnumbers] ).These transceivers support single mode fiber up to 10km in distance, comparedto the 50-75 meters supported by the Shortwave SFP transceivers.
Like theShortwave SFP transceivers we already have available, these Longwave transceivers have "N-2" support, which means they can support two generations back: auto-negotiate down to 4 Gbps and 2 Gbps speeds. If you still have 1 Gbps equipment, now is a good time to consider upgrading those, or keep a few 4 Gbps ports available that can auto-negotiate down to 1 Gbps speed.
Mainframe clients that sent data to a remote Business Continuity/Disaster Recovery (BC/DR) location often used "channel extenders", which were special boxes used to minimize performance delays when transmitting FICON across long distances. This was especially helpful for z/OS Global Mirror (what we used to call XRC) as well as electronic vaulting to tape.
Now, this functionality can be part of the directors and routers, eliminating the need for separate equipment.This is available for the SAN768B and SAN256B directors, as well as SAN18B-R and SAN04B-R routers.
Before the merger between Brocade and McDATA, IBM offered SAN18B-R routers from Brocade, and SAN04M-R routers from McDATA. The former had 16 Fibre Channel (FC) ports and two Ethernet ports, and the latter was less expensive with just four ports.Brocade came up with a clever replacement for both. The [IBMSystem Storage SAN04B-R] router comes by default withtwo active FC ports and two Ethernet ports, but also with 14 additional FC ports inactive. A "High Performance Extension" feature activates these additional ports, bringing the SAN04B-R up to the SAN18B-R level, and allows it to support the FICON Accelerator feature above.
So, instead of having specialized channel extenders at both primary and secondary sites, you can havea director with FICON Accelerator at the primary site, sending FICON over Ethernet to a 1U-high router (also running the FICON Accelerator) at the secondary site, whichcan greatly reduce costs. The FICON Accelerator can in some cases double the amount of data transfer throughput,but of course, your mileage may vary.
On the disk side, the [IBMSystem Storage DS3000 series] disk systems have been enhanced, withsupport for 450GB high-speed 15K RPM SAS drives, RAID-6 double-drive protection, more FlashCopy point-in-time copies,and more partitions.On the DS3000, "storage partitions" is what the rest of the industry calls "LUN masking". A storage partition allowsyou to isolate a set of LUNs to only be seen by a single host server, or host cluster that shares the same set ofLUNs. Some clients felt that the default of four partitions was too low, so now up to 32 partitions can be configured.(This is not to be confused with "Logical Partitions" that isolate processor and cache resources available on theIBM System Storage DS8000 and other high-end storage disk systems.)
IBM also extended the Operating System support.The DS3000 series now supports Solaris, either on x86 or SPARC-based servers. The DS3300 iSCSI support now supportsLinux on POWER. The DS3400 allows support of IBM i (the new name for i5/OS V6R1) through the VIOS feature.
The [IBMSystem Storage DCS9900] is a bigger, faster version of the DCS9550. Like the DCS9550, the DCS9900 is designedfor high performance computing (HPC) workloads. The DCS9550 supported up to 960TB in two frames, with 2.8 GB/sec throughput,and an optional disk spin-down capability.The new DCS9900 can support up to 1.2 PB in two frames, with 5.6 GB/sec throughput, but no spin-down capability.
So whether your data center is filled with System z mainframes, or other open systems, IBM has a solution for you.
Today, IBM announced its latest [BladeCenter S] with integratedredundant SAN fabric and disk storage inside the chassis. The tag line is "Data Center Capability, without the Data Center!"
I've gotten a few calls on this today, so I thought it would be good to blog about. To understand what is new,you need to understand what we had in other BladeCenter chassis. In those other chassis, there were up to 14 bladeservers on the front, and switch modules for FCP and Ethernet on the back. The entire chassis was rack-mountedto be connected to external devices.
The BladeCenter S was announced a year ago.With the new "BladeCenter S" chassis, the storage can be included inside the chassis, as well as connecting tothe outside world. It is designed to be stand-alone, rather than rack-mounted, plugs into a standard 100v-240v office power outlet,and includes a dust filter in caseyou keep it close to the floor, under your desk for example.

(Here's also a more detailed[7-minute video] with fellow IBM colleague Alex Yost.)
Here's what you can get with the BladeCenter S:
Up to six(6) server blades that can do the work of 25-45 traditional servers.
Up to two(2) storage blades, each can have six(6) SAS or SATA disk drive modules (DDMs)
Up to four(4) switch modules, with a variety to choose from
Shared KVM, DVD/CD burner, and USB port. You can designate which blade has access to these, useful forinstalling software, attaching external devices, and so on.
The blades use either Intel, AMD or POWER processors, so you can run Windows, Linux, AIX, and [IBM i] (the newname for i5/OS V6R1).
Back 20 years ago, I worked with people with System/36 and System/38 systems. They loved it. Everything inone package. This grew into the AS/400 server. Having everything in one package was such an advantage thatIBM extended this to include a few "x86 blades" to run Windows applications but share the storage and networkresources.
Now IBM has taken this one step further. The older models assumed the majority of applications run underIBM's OS/400 or i5/OS operating system, but this new BladeCenter S does not make that assumption. You canmix and match different blade servers as needed, and run the operating systems you need.
This is an ideal packaging for Small and Medium sized Business (SMB), remote branch offices, and retail stores.In fact, more than 4,000 retail stores plan to run their operations using BladeCenter S this holiday season! For moreon this announcement, see the [IBM Press Release].
Well, it's Tuesday again, which means IBM announcement day. With our [big launches] we had this year, there might be some confusion on IBM terminology on how announcements are handled.Basically, there are three levels:
Technology demonstrations show IBM's leadership, innovation and investment direction, without having to detail a specificproduct offering.Last month's[Project Quicksilver], for example, demonstrated the ability to handle over 1 million IOPS with Solid State Disk.IBM is committed to develop solid state storage to create real-world uses across a broad range of applications, middleware, and systems offerings.
A preview announcement does entail a specific product offering, but may not necessarily include pricing, packagingor specific availability dates.
An announcement also entails a specific product offering, and does include pricing, packaging and specific availability dates.
With our September 8 launch of the IBM Information Infrastructure strategic initiative, there were a mix of all three of these. Many of the preview announcements will be followed up with full announcements later this year. Today, the IBM Tivoli Advanced Backup andRecovery for z/OS v2.1 was announced.
Note: If you don't use z/OS on a System z mainframe, you can stop reading now.
As many of my loyal readers know, I was lead architect for DFSMS until 2001, and so functions related to DFSMS and z/OS are very near and dear to my heart. For Business Continuity, IBM created Aggregate Backup andRecovery Support (ABARS) as part of the DFSMShsm component. This feature created a self-contained backupimage from data that could be either on disk or tape, including migrated data. In the event of a disaster,an ABARS backup image can be used to bring back just the exact programs and data needed for a specific application, speeding up the recovery process, and allowing BC/DR plans to prioritize what is most important.
To help manage ABARS, IBM has partnered with [Mainstar Software Corporation]to offer a product that helps before, during and after the ABARS processing.
ABARS requires the storage admin to have a "selection list" of data sets to process as an aggregate.IBM Tivoli Advanced Backup and Recovery for z/OS includes Mainstar® ASAP™ to help identify the appropriatedata sets for specific applications, using information from job schedulers, JCL, and SMF records.
ABARS has two simple commands: ABACKUP to produce the backup image, and ARECOVER to recover it. However, ifyou have hundreds of aggregates, and each aggregate has several backups, you may need some help identifyingwhich image to recover from.IBM Tivoli Advanced Backup and Recovery for z/OS includes Mainstar® ABARS Manager™ to present a list ofinformation, making it easy to choose from. To help prep the ICF Catalogs, there is a CATSCRUB feature for either"empty" or "full" catalog recovery at the recovery site.
The fact that storage admins may not be intimately familiar with the applications they are backing up is a commonsource of human error. IBM Tivoli Advanced Backup and Recovery for z/OS includes Mainstar® All/Star™ to help validate that the data setsprocessed by ABACKUP are complete, to support any regulatory audit or application team verification.This critical data tracking/inventory reporting not only identifies what isn't backed up, so you can ensure that you are not missing critical data, but also can identify which data sets are being backed up multiple times by more than one utility, so you can reduce the occurrence of redundant backups.
With v2.1 of Tivoli Advanced Backup and Recovery for z/OS, IBM has integrated Tivoli Enterprise Portal (TEP)support. This allows you to access these functions through IBM Tivoli Monitor v6 GUI on a Linux, UNIX or Windowsworkstation. IBM Tivoli Monitor has full support to integrate Web 2.0, multi-media and frames. This meansthat any other product that can be rendered in a browser can be embedded and supported with launch-in-contextcapability.
(If you have not separately purchased a license to IBM Tivoli Monitoring V6.2, don't worry, you can obtainthe TEP-based function by acquiring a no-charge, limited use license to IBM Tivoli MonitoringServices on z/OS, V6.2.)
In addition to supporting IBM's many DFSMS backup methods, from ABARS to IDCAMS to IEBGENER, IBM Tivoli Advanced Backup and Recovery v2.1 can also support third-party products from Innovation Data Processing and Computer Associates.
As many people re-discover the mainframe as the cost-effective platform that it has always been, migratingapplications back to the mainframe to reduce costs, they need solutions that work across both mainframe anddistributed systems during this transition. IBM Tivoli Advanced Backup and Recovery for z/OS can help.
