RE: Power8 PCI slots

Larry,

Are you stating that the embedded Power8 DASD controller is better(faster) then a 5913?
And it can drive not only CEC DASD but also XP24S (5887)
This is a BIG first for i5 / Power.

7.2GB effective Cache.
Big power this time.
18 Internal Drive bays plus 8 dedicated SSD slots (in dual socket only) Can drive an XP24S (5887) too.

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
