RE: Load Source Placement - Best Practices.

I just loaded a P8 with four mirrored SSDs in the CEC. Start of D mode IPL
with initialization of the SSDs to IBM I loaded with all the LPPs -- 2
hours. IPL after it was all done <3 minutes.

I did load the LIC, OS, and LPP from an LTO5 SAS connected tape I created
from my system with all the PTFs already applied.

Sue Baker might have some input here but I've never seen any such document.
It might be 'Best IPL time' to do this but with the POWER8 servers there
would be no gain putting the load source in the 5887, SSD or not.

What I will say is IPLs from SSD off pretty much ANY RAID card especially
when mirrored are incredibly fast. I've seen 2 minutes or less.

Expansion Unit (or equivalent) as opposed to having it reside in the CEC
attached to the MFIOP.

Has anyone seen any references to this, especially on the newer Power8

servers?
