iSCSI Target and CGE Ports
I was wondering what would be the best setup for my Celerra NS120 for the current situation.
I have 4 CGE Ports all 1 Gbit. Two cge ports on server_2 go are no bound, just single ports, no EC or LACP. Each port goes to a single seperate switch. Switch A and B. Subnet is 192.168.1.1 iscsi-1 and 192.168.1.2 -iscsi-2. I have 4 HP DL 360 connected to switch A & B.
I bought a 7 Cisco UCS Blades/chassis and 10Gib Nexxus Switches (2). I took cge2 and cge3 from server_2 and bound into 1 EC interface and assigned an IP of 10.222.35.11. Did this IP scheme to match our new VLAN scheme. We put cge2 ,plugged it into Nexxus switch A and cge3 and plugged it into Nexxus switch B. This was needed so the Cisco UCS could talk to our EMC.
I have had a few vendors give me there opinions but not sure what to do. One EMC vendor told me i should take each cge port and assign it a single IP and create a single target per CGE port. Then run one vmware vnic assisgned as an iscsi port to each target..
Currenly with the 2GB EC isn't that the same as 2 targets? What do you guys think
