A bit more detail on your setup might also yield tuning suggestions at least on NetApps from this list...
- NFSv3?
Yes.
- TCP or UDP mounts?
TCP.
- through a switch? what type?
Yes, a Cisco Catalyst 6509.
- jumbo frames?
No.
Any tuning suggestions?
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 not sure about the Celerra config. EMC has been out here several times checking and double checking the config, so I'd think they have it setup optimally. I haven't actually touched the config personally.
Should the Celerra get better write performance?
