I have just (generating some traffic here in doing so) added a pair of stacked Cisco 3750-E switches with redundant 10g connections. Right now they are just using etherchannel with default MTU. Once everything else is running properly I'll try LACP and probably an MTU of ~7500.

The only problem I see is it's VERY easy to burn the CPU when doing large writes because I have the TOE cards in a VIF...which disables the TOE functionality.

Hi all

Reading on superior results reached in certaing environment (NetApp NFS with Oracle ad example) I'm looking for some direct experience and informations about performances, benchmarks, infrastructure used - I mean also exactly model and brand of switches :-) - and so on. So that, more on the relatively new world of 10 Gbps networks.

Does anyone direct experience? Are you using it in your site?

Thanks in advance

Hello,

we use FAS6070 with 2x10Gbps and Oracle DB's over NFS for nearly 2 years now.

Our switches are Nortell 8000 series, so we use a technique called SMLT which allows us to use both links while they are connected to different switches. The databases run quite well over NFS. Sadly only the filers are using 10Gbps, the servers don't have 10Gbps. Nevertheless we see good roundtrip times and throughput, but as always there are some people who argue that SAN would be faster.

Sadly we have no global benchmark tests, only results while investigating problems.

One thing we came along is when using a vif with two PCI-X-10Gbps-NICs we see a strange performance slump for 32k frames, but only on one interface. Right now we are searching together with netapp for the root of this problem.

Regards

Jochen
