I'm evaluating a NetApp F840C and an EMC Celerra. I'm using a benchmark program called Iozone (http://www.iozone.org/) to test NFS throughput. Are there any other benchmark programs out there anyone would suggest I try?
You might look at:
http://www.coker.com.au/bonnie++/ http://www.netapp.com/tech_library/3022.html (Postmark from NetApp)
Also, depending on your ultimate application, you might try some of the other programs that simulate specific ones -- those are listed at the bottom of the bonnie page.
A bit more detail on your setup might also yield tuning suggestions at least on NetApps from this list...
- NFSv3? - TCP or UDP mounts? - through a switch? what type? - jumbo frames?
on a Sun E4500, and the numbers I'm getting are about 30 MB/sec read/write for the F840 and 20 MB/sec write and 25 MB/sec read on the Celerra. Both are connected with Gigabit Ethernet.
does the Celerra have NVRAM write-cache? that might be the cause of the NetApp showing better write performance...
I'm interested in a summary of the comparison when you are done...
Thanks, Adi
