We are running CIS5.7R2 on AIX 6.1 TL 6 SP5 on Power 6’s with our sites deployed over multiple filesystems that are configured in a SAN pool
using JFKS2 journeling. When we upgraded from 5.6R3 to 5.7R2 we tripled our old ulimit settings for user accounts hci and hcitest.
Here are our current values:
alin1hub:/quovadx/qdx5.7/integrator/allina_prod5/Xlate >ulimit -a
threads(per process) unlimited
processes(per user) unlimited
The Power 6s are the 550 models; 4-way with 4.2 G CPUs and 16 G memory configured per our operating system group.
We are planning to move to AIX virtualized hardware soon running in AIX 7 SP1 – our operating system group desires to up our OS level.
And run on Power 7s’.
To date we have had no performance issues or I/O contentions; however, in the old days we had ALL our sites on ONE filesystem and yes ! we experienced I/O hits and slowness.
I hope this helps you out.
