I'm looking at getting 3 hosts and a SAN set up with iSCSI for a VMware envoroment and have had several companies come to us with suggestions (small team and will need help with implementation). They have suggested an IBM setup using 2x 4 port 1GBE iSCSI cards on the SAN which is a DS3524 and then running a Cisco 2960S stack using 6 connections per host.
I went away and came back with a solution (for the same price) using 2x 2 port 10GBE iSCSI controller SAN which is a Dell 3620i using a Cisco 2960S stack with 2x 10GBE ports each and using 8 connections per host for improved performance. They can't match this in terms of price and have suggested the IOPS would be less in this configuration due to less channels on the SAN controllers (8x1GBE vs 4x10GBE). Are they talking rubbish to try and get a sale? Couldn't find much online but wanting to make the right decision.
I can post the full hardware specs of this solution if required.
