  • SAP Tests Prove i 7.1 Performance Boost Over i 6.1

    April 26, 2010 Timothy Prickett Morgan

    The new i For Business 7.1 operating system for Power Systems servers is not just about gussying up i 6.1.1 a little and slapping a new label on it, but making some real changes to the operating system to goose performance on a number of workloads. As The Four Hundred reported last week, IBM made a bunch of improvements in the DB2 for i database, and as it turns out IBM has put the new Power 750 server through some benchmark paces to show how the upgraded software can goose even a new machine.

    While i 6.1.1 will technically run on Power7-based servers, i 7.1 was designed to more fully exploit its features. Just as i 7.1.1, which is due before the end of 2010 and most likely with entry and high-end machines around the August-September timeframe (as this newsletter revealed in February), will more fully exploit the Power7 iron, the kicker i 7.1.2 and i 7.1.3 will do even more when they come out in early and late 2011, respectively.

    I already walked you through the SAP business intelligence benchmark tests IBM has run on Power6, Power6+, and Power7 machines using the Business Intelligence-Mixed Load, or BI-MXL, test. This is the third generation of SAP BI tests IBM has used to gauge the performance of data warehousing on iSeries and Power Systems machines. Those tests were run to show how much more oomph a modestly configured Power 750 had over older Power 520, 550, and 570 servers.

    The most recent test was done specifically to show the performance jump for BI work that could come just through upgrading from i 6.1.1 to i 7.1. To demonstrate, IBM took a single-socket Power 750 with eight-cores and 32 threads, one-quarter of the capacity of the machine, and tossed in 128 GB of memory. On the BI-MXL test, that Power 750 was able to process 241,526 query navigation steps per hour against a database of 300 million records running i 6.1.1, its integrated DB2, and SAP’s NetWeaver 7.0 middleware. That machine ran at 99 percent CU utilization on the test. Last week, IBM said that it took the same exact machine and slapped on i 7.1 on it, and was able to process 278,462 query navigation steps per hour on the test. That’s a 15.3 percent increase in performance at no extra cost–beyond the hassle of upgrading to a new operating system, of course.

    Integrate Virtual Tape to Automate Your Backups And Strengthen Your Ability To Recover From Cyber Attacks And Disasters

    With most IT departments stretched thin, finding something that can quickly free up IT time is definitely a bonus. That’s why it’s important to stop and take a look at integrating virtual tape into your backup and recovery. Virtual tape is one of those technologies where once you have it, you’ll wonder why you didn’t do it sooner. See a demo and get a $50 gift card.

    But what is it about using virtual tape that makes it so worthwhile? Why is it that so many IBM i shops are already using or considering using virtual tape for all or part of their backup and recovery systems?

    Virtual tape and virtual tape libraries offer a way to both simplify and strengthen backup and recovery operations. By incorporating virtual tape technology, automation of backups becomes possible resulting in hundreds of hours saved annually for IT departments and personnel.

    “We needed to find a replacement that would lower the maintenance cost and reduce complexity of our backup and recovery functions without a major disruption to our operations.” David Fray, Director of Enterprise Systems, ABC Financial

    LaserVault ViTL is a virtual tape and tape library solution developed specifically for use with IBM Power Systems (from AS/400 to iSeries to Power 9s). With ViTL you can:

    • Replace physical tape and tape libraries and eliminate associated delays
    • Automate backup operations, including the ability to purge or archive backups
    • Remotely manage your backups – no need to be onsite with your server
    • Save backups to a dedupe appliance and the cloud
    • Recover your data at lightspeed greatly improving your ability to recover from cyberattacks
    • And so much more

    Sign-up now to see a ViTL online demo and get a $50 Amazon e-gift card when the demo is complete as our way of saying thanks for your time. Plus when you sign-up you’ll receive a free facts comparison sheet on using virtual tape vs tape so you can compare the functionality for yourself.
