RE: Power8 PCI slots



fixed

Rob,

If I totally collapsed all my LPARS, and made all my LPARS a guest, yes, maybe, but probably not doable.
SSD DASD is for Production LPAR only.
Remaining SAS DASD is for R&D LPAR and Upgrade LPAR(S)
Each LPAR needs FC for tape library.
Might save on 1 ethernet.

4-5913 - PCIe2 1.8GB Cache RAID SAS - 2 for each LPAR
3- 5767 - PCIe 1Gb Ethernet UTP -1 each for 3 LPARS
2-5735 - 8 Gigabit PCI Express Dual Port Fibre Channel Adaper - 1 each for 2 LPARS
1- 2893 - PCIe 2-Line WAN w/Modem - Production RS232 line and MPLUS notitication.
1- 5901 - PCIe Dual - x4 SAS Adapter - for 2nd floating OPT

Paul

Do you really need all 11 slots? Are some of these numerous fiber or ethernet cards to support multiple lpars which would be better served being virtualized via VIOS?

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
