VMWARE QUESTION

I am running ESX 4.1 with a single iSCSI connection to my storage. I have 30 vms running, all on luns from the san. The ports are connected to the san via a gbs switch.

I am experiencing a bit of congestion on this one channel and I want to know which one of the following will better suit my needs:/

1) nic team the iSCSI channel to obtain 2GB throughput on the iSCSI channels (is this possible with iSCSI storage?)
2) Create a second iSCSI channel and present half of the luns via this channel. Is it possible to setup mu;tiple channels going to the same san using the software initiator?

You should create a second vmkernel port and use 2 nics.  Afterwards configure multipathing as descibed in the link.

You may also want to explore enabling Jumbo Frames on your iSCSI connections to your storage, switches that connect storage to servers, and also on the SAN, if all your switches and SAN support Jumbo Frames. In our test enabling Jumbo Frames on Software iSCSI out performed dedidicated Hardware iSCSI initiators, and reduced read and write disk latency to almost 0 (zero).

if you requiroe any further assitance please ask.
