So I am benchmarking a pile of iSCSI SAN's, trying to evaluate them for a client using IOmeter. I am using OpenPerformanceTest.icf.
Up until now, my standard build for IOmeter is:
- XP-32 bit
- 1 GB RAM
- 8 GB C:\ on LSI Logic Paralell (0:0)
- 8GB unformatted PHYSICALDRIVE1. LSI Logic Paralell (1:0) (eagerzeroedthick)
This has worked great for comparing the SAN's, I have been running tests on 4 different SAN's for weeks now and have some solid ideas about the capabilities of each. Overall, everything performed well, and there were almost never any errors in "Total Error Count"
Ultimately the client asked that I run some benchmarks using their standard build for Server 2008 X64:
- Server 2008 R2 X64
- 40 GB C:\ on VMware pvscsi (0:0)
- 8 GB unformatted PHYSICALDRIVE1 on VMware pvscsi (1:0) (eagerzeroedthick)
- Firewall off, service stopped
- IOmeter installed and run as "Run as administrator"
When using the W2K8, the first test (Max throughput, 100% Read) runs OK, then every other test develops thousands of errors (tens of thousands "Total Error Count" errors). I just don't get it. I have read VMware whitepapers indicating that the VMware pvscsi adapter can be used with IOmeter for benchmarking.
I must have missed something. Any help? Thx in advance.
