Re: IVM IBMi 7.1 Performance

[Roberto José Etcheverry Romero <yggdrasil.raiker@xxxxxxxxx>]

Wait,

Are you using internal storage via IVM for the IBM i partition?
Do you have the complete configuration available? You might have made a
RAID5 with a no cache controller (not up to Power8 on my redbook reading
yet) and running VIOS on top of it. I assume you will not be using any
external SAN storage right?
