Reader Feedback On Power S814 Power8 Running IBM i

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.
