Re: Rép. : Question of a Newbie to POWER Systems

I agree with the 3/6. Likely with no RAID card providing cache for these drives so I stand by my initial guess that performance of these drives very likely a bottleneck.

In addition Mauri also followed up with a requirement to partition his machine and do remote copy. Thus the machine as currently configured will require some 'more power' so to speak.

OTTOMH the best direction here would be to install VIOS on these drives and use Fiber back to the SAN via SVC as he suggested. The SAN can then hold the other partitions. The SAN could also be used to mirror those partitions remotely solving that piece of the puzzle. More memory will be required of course as 8GB isn't enough for VIOS and a pair of IBM i partitions, i would start with 32GB there.

This is a Single VIOS solution (i.e. no redundancy) so a VIOS failure would take down the entire system. Additional I/O hardware could be added to support a second VIOS host however.

Since the OP said

"It contains 3 disks of 140 GB - Which are RAID-1 mirrored totalling 420GB

I was assuming it was 3 pairs/6 physical units.

Since he said RAID1-mirrored, I think it's really 4 drives rather than 3.
If not, that would be the first thing to fix, because a disk is
unprotected.
