  • Reader Feedback On Power S814 Power8 Running IBM i

    July 7, 2014 Hey, TPM

    Thank you for the news stories and industry commentary. Coming back to the IBM i fold after eight years, this is exactly what I need.

    I have a comment on your P05 Power8 story though. You mention that the memory cap is the same as IBM put on the Power7+ P05 machine, which is not what I have encountered. I have just installed a Power7+ 710 Express and it has a 256 GB memory limit but is a P05 box.

    Kind regards,

    –Matthew

    That cap is only on the Power 720 and Power 720+, which has room for expansion for disk and flash. The Power 710+ is, as you say, a P05 machine, but you can only get a few disks in it and I believe there is limited connectivity to external I/O drawers, too. I was thinking of Power 720-class machines compared to the Power S814. There is no analog I guess to the Power 710+ in the lineup any more. . . .

    If you can get by with a few disk bays, the Power 710+ is great. If you want to marry it to a SVC+FlashSystem 840, you can build a pretty powerful server-IOPS machine.

    –TPM

    I have the Power 710 Express attached to a V3700 as, right now, the disk performance is sufficient. I have experience of the SVC and love that technology. However an S814 with double or quadruple the 64 GB memory cap will give me that extra horsepower I could happily make use of. Having 39,800 CPW with only 64 GB RAM is a little miserly.

    –Matthew

    Do the Math When Looking at IBM i Hosting for Cost Savings

    COVID-19 has accelerated certain business trends that were already gaining strength prior to the start of the pandemic. E-commerce, telehealth, and video conferencing are some of the most obvious examples. One example that may not be as obvious to the general public but has a profound impact on business is the shift in strategy of IBM i infrastructure from traditional, on-premises environments to some form of remote configuration. These remote configurations and all of their variations are broadly referred to in the community as IBM i hosting.

    “Hosting” in this context can mean different things to different people, and in general, hosting refers to one of two scenarios. In the first scenario, hosting can refer to a client owned machine that is housed in a co-location facility (commonly called a co-lo for short) where the data center provides traditional system administrator services, relieving the client of administrative and operational responsibilities. In the second scenario, hosting can refer to an MSP owned machine in which partition resources are provided to the client in an on-demand capacity. This scenario allows the client to completely outsource all aspects of Power Systems hardware and the IBM i operating system and database.

    The scenario that is best for each business depends on a number of factors and is largely up for debate. In most cases, pursuing hosting purely as a cost saving strategy is a dead end. Furthermore, when you consider all of the costs associated with maintaining and IBM i environment, it is typically not a cost-effective option for the small to midsize market. The most cost-effective approach for these organizations is often a combination of a client owned and maintained system (either on-prem or in a co-lo) with cloud backup and disaster-recovery-as-a-service. Only in some cases of larger enterprise companies can a hosting strategy start to become a potentially cost-effective option.

    However, cost savings is just one part of the story. As IBM i expertise becomes scarce and IT resources run tight, the only option for some firms may be to pursue hosting in some capacity. Whatever the driving force for pursing hosting may be, the key point is that it is not just simply an option for running your workload in a different location. There are many details to consider and it is to the best interest of the client to work with an experienced MSP in weighing the benefits and drawbacks of each option. As COVID-19 rolls on, time will tell if IBM i hosting strategies will follow the other strong business trends of the pandemic.

    When we say do the math in the title above, it literally means that you need to do the math for your particular scenario. It is not about us doing the math for you, making a case for either staying on premises or for moving to the cloud. There is not one answer, but just different levels of cost to be reckoned which yield different answers. Most IBM i shops have fairly static workloads, at least measured against the larger mix of stuff on the public clouds of the world. How do you measure the value of controlling your own IT fate? That will only be fully recognized at the moment when it is sorely missed the most.
