RE: Power8 PCI slots



fixed

It will be the best disk controller you have ever seen in your life. 7GB of write cache compressed (I think about 1.5GB uncompressed) and will scream driving all the disks you can put in the CEC as well as externally attach, including SSDs. This is basically the new High Performance controller they announced end of last year.

Larry,

Do we know the specs on the Power8 base Raid controller?
Is it limited as in the past (P5, P6, P7) or have they given it some sizable cache?

You would need a machine with two processor modules installed to use all the slots. With just one module you get a little over half the slots.

This may a bit early and maybe pre-mature.
Now that the Power8 PCI slots are again "hot swappable" (Power 5 was, Power 6 and Power7 not).
Current Power7 is configured with 2 loops, (4 5913) each 5913 pair is split in one of two 5877, in case of drawer and/or loop failure.

If I were to upgrade to a Power8, at some point, I theoretically could eliminate my two 5877, put all 11 slots in Power8 CEC.
Not only would this eliminate all expansion drawers, but also both GX++ loops.
Hardware maintenance would also be reduced.

One negative would be that I'd be maxed, no room for expansion, currently I have 9 empty slots.

Any other negatives or thoughts from the group.

Thank You
