Hello,
I got a disk array appliance of 8 disks 1T each (UltraStor RS8IP4). It will
be used solely by PostgresQL database and I am trying to choose the best
RAID level for it.
The most priority is for read performance since we operate large data sets
(tables, indexes) and we do lots of searches/scans, joins and nested
queries. With the old disks that we have now the most slowdowns happen on
SELECTs.
Fault tolerance is less important, it can be 1 or 2 disks.
Space is the least important factor. Even 1T will be enough.
Which RAID level would you recommend in this situation. The current options
are 60, 50 and 10, but probably other options can be even better.
Thank you!
