Remember to look at the "real" numbers. In other words, how many filesystems are used (1 in the case of the 24 node GX cluster, 2 in the case of most if not all netapp clusters, 1 in the case of nearly all the rest of the netapp cases, everybody else usually use an obscene/unrealistic number of filesystems)

The one real flaw I think is in this benchmark is that it pretty much evenly distributes I/O evenly across all filesystems. Sent from my Verizon Wireless BlackBerry

Toast{ed} types,

What is the benchmark site or reference paper I should look at for NFS perf numbers for filers?

The below scenario is getting interesting in that the NFS clients (RAC hosts) are Sun T2000's with known on-board GigE driver issues. We are patching as I type...

As a brainless test this morning I took *off* the "noac" mount setting and get 4-5X the perf then with it.

I see myself going down that fabled path of "well if its a 3020 with GigE and CAT 6509 infra no jumbo frames you *should* get X perf" It would be good to compare with some conservative and reasonable numbers somebody else already wrote down.

And no EMC guys allowed to play here.

;-)

TIA as always,

-Rob

Toasters,

My DBA just came to me and complained that a Ora RAC 10g build took 18 hours when using a Filer NFS mount. Seems I've heard of this issue before but forget the fix. Has someone seen this before ?

TIA
