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?
I'm using iozone like this:
iozone -a -e -f /emc/foo -U /emc
or
iozone -a -e -f /netapp/foo -U /netapp
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.
The -e option does an fsync/fsflush after every write, and the -U does an unmount/mount of the filesystem between every test. This seems to eliminate the huge throughput numbers I was seeing before, due to filesystem cache. (The E4500 has 4 GB of memory.)
Any suggestions would be appreciated!
