Put simply. performance is terrible when switch is in my network and clients are acessing the 450 (which is attached to the switch with a crossover cable).
If I remove the the switch from the network, all is well.
I've sent the switch back to be tested and it is fine. Other UNIX servers in my network give great performance with or with the switch as do the clients.
I've thought about half/full duplex issues on the 450's ethernet but its set correctly on the netapp and I've read that the 450 does support full-duplex anyway.
Any ideas as to why my 450 doesn't like the switch?
None whatsoever.
We ran into a similar problem with a F210, Cisco Catalyst and Sun Ultra Enterprise 1s and 3000s.
Checked everything. Cisco checked the catalyst. Sun checked the Suns. NetApp engineers came and played.
Gave up in the end...it just appeared everytime the switch came into the equation performance dropped off. Back to back Ethernet cable was just fine.
