TOE, Teaming Nics, best option for performance.

I'm putting together a SAN Melody system (Win based iSCSI SAN). For this role I have a Dell 1950 with 2 Nic's. 1 is the on board dual Gb Broadcom which has support for TOE and I see an option of teaming. As well I have an Gb Intel PT/1000 Dual card. Doesn't seem to have TOE, but I suppose I can team it. Then at the other end of things I have a switch that can aggregate links.

Since this will be an iSCSI SAN I need the max throughput possible from my options. I have never teamed up nics, or used TOE so I'm a little lost. I feel like the Broadcom in a team using TOE would be best, but figured I'd see what you guys think.

    Accepted Solution

    TOE is going to allow the NIC to do the processing involved with packaging up data packets.  Its a great thing for iSCSI since it alleviates CPU overhead.

    Use the NIC teaming for the LAN access.

    Assisted Solution

    In addition to the above you can't use the Microsoft iSCSI initiator with teaming, use MPIO instead for redundancy (and load balancing if you can set the preferred path and have more than one LUN). Of course DataCore might have some other way of diong it, I'm not sure whether you are talking about the target or initiator.

    SANmelody eh, don't let anyone run defrag on a disk since it may de-virtualize the storage and use the whole reserved space.
