IBM POWER 720 8205-E6B
Posted on 2011-10-27
configuring a POWER 720 server. Loading AIX 6.1. Server has base RAID feature 8630 with all drive slot filled. 8 total drives.
Wanting to mirror boot on hdisk0 and hdisk1.
first, once 2 physical drives are mirrored boot devices, is it still a possibility to use other RAID sets within that pair.
also wondering about performance.
What is most efficient RAID and grouping ?
base feature 8630 offers RAID's 0,5,6,and 10.
Is pairing the best choice for efficiency ?
What happens with the first pair of mirrored boot drives as far as options to include them into one big RAID set with all the drives included if that is the best case ?
