E4500 and A5200 Throughput issues
2007-12-25 5:01:00
drives. OS Version is 2.9, with all the latest patches applied.
It is running as an Oracle 9i DB server (9.2.0.5). Disk is configured
Raid 0+1 for data files and Raid 1 for log files.
Running some sql scripts shows the throughput peaking at 750 I/O's per
sec.
Comparing it to a IBM Netfinity 7100 (the old server) single 700Mhz
intel CPU, with internal scsi disk configured similarly. Throughput
for the same scripts on this server peaks 15000 I/O's per sec.
Needless to say I have an unhappy Manager.
Questions:
1) Are there any parameters that I could tune?
2) Is there some sort of HW mismatch going on, never managed fiber
attached disk before?
3) Is this all I should expect.
TIA

P.S. Filesystems are UFS and I have tried both Async and DirectIO, with
negligible results.
