Hi.

I got a HP c3000 cabinet with BL460 servers, i have 4switches and i whant to use 2 of them to connect to my iSCSI network where i have a p4300 cluster with 6nodes, the p4300 network cards are set to use ALB.

What "teaming" option of the network cards do i want to use for best perfomace?
Is this the best way to build?
What about jumbo frames and flowcontrol, any one got expericense?

What OS/initiator do you have? For example with MS iSCSI initiator you don't use teaming but multipath.

Hi,

I use MS iSCSI initiator.

Should i use multipath and not teaming?
Will that realy increase the speed to the san?

It won't necessarily increase the speed but it will give you redundancy and it's supported. If you have more than one LUN you can set the prefeered paths, then you qwill share thwe bandwidth a bit better. Uning jumbo frames might squeeze a bit more through but that doesn't do much to improve the latency you get with iSCSI; you may not have enough disks to get 1 gig anyway, needs wuite a few spindles for that.

Commented:
Teaming : don't user Microsoft Bridge about teaming, in that case you need to use also LACP/Etherchannel on the switch for aggregate the port.
Hower i think is better use failover of P4300 instead of Server teaming, however if you wanna use, use HP software for teaming.

Jumbo: is valid if you have virtualization layer (for the vmdk or vhd image) in the other case don't use

@DOOMAN, have MS chaned the rules then? The copy I have of the iSCSI user guide says "Microsoft does not support the use of NIC teaming on iSCSI interfaces..." so I've always said use MPIO instead.

(can't post the link but google for ~"ms iscsi initiator" teaming~ and it's first hit)

Hi,  sorry for late response.

I have tried MPIO on cluster shared volumens and that was not a good idea.

Does anyone know wy NIC teaming and iSCSI dont work?

Commented:
Matt, you can use MPIO and teaming, make sure to install HP network utility, create a team for your NICs and under the settings tabs enable netflow. Reiew this document carefully to setup MPIO on Windows Server.

What kind of switched are you using, Cisco or HP Virtual connect in C3000? there are set o instrucitons that you have to follow, I will post the link for that doc tomorrow.

Commented:
Matt, it is highly recommended that you create a separate VLAN to handle your iSCSI traffic, hope you have more that two NIC on your blade to handle this.

Hi,

I have tried already to team 2 NIC (yes in separat vlan) and that works great!

I am thinking of teamin 2 NIC´s that are on separat switches, does that work?

Commented:
is this on your blade server? and are you using virtual connect?

Author

Commented:
This is on my blade server.

I am not using virtual connect
Commented:
Then read this document, this is recommended by HP to set up IP Storage Configuration with Dual Switches W/ALB and MPIO. short document and extremely useful.
