We are considering replacing our current NFS server which is a Dell 6650 with Quad Xeon MP 2.7 procs, 12GB RAM, 4GB NICS running RHEL3 with a 3050 cluster.
We are running 7.2K SATA drives from Winchester Systems connected via an U320 SCSI to the Dell today and we would be running NetApp's 250GB SATA drives on the 3050 cluster.
NetApp posts IOPS as a performance metric but I am unable to find anything like that related to my Dell configuration so trying to figure out the performance gain and justifying the money we would be saving is becoming very tough. I can look at reads and writes per sec using IOSTAT on my Dell but I am not 100% sure its apples to apples compared to IOPS.
Can anyone shed some light on this for me?
Thanks !
