Sun Solaris SPARC Disk Arm Utilization
2007-12-25 4:28:00
running Sun LDAP 5.1 SP3.
I am gathering stats via iostat but I am being asked specifically for "disk
arm utilization" information.
I am running:
iostat -pnx 1 2
extended device statistics
r/s w/s kr/s kw/s wait actv wsvc_t asvc_t %w %b
device
0.0 2.0 0.0 8.9 0.0 0.0 0.0 7.0 0 1

0.0 23.8 0.0 899.0 0.0 0.2 0.0 7.0 0 16
c1t11d0
0.0 23.8 0.0 899.0 0.0 0.2 0.0 7.0 0 16

Our goal is to ensure that the new Sun boxes we purchase will enough disk arms
to provide the throughput that is demanded by the LDAP.
Any recommendations, or comments are appreciated.
