MSA 2012i SAN and ESX / vSphere 4.0 -- how??

Has anyone got this working with hardware iSCSI cards??

My understanding is that I would install 1 hardware iSCSI HBA card into each of our 3 ESX hosts, then configure each dual-port HBA card within each host with its own vSwitch and put all the backend SAN traffic on it.

Getting new cards for the hosts is about 60% less $$$ than replacing the controllers.

Any and all information would be much appreciated.

Thank you, Tom

An iSCSI HBA is not a pNIC so you can't connect it to a vSwitch. It appears as a plain "vmhba" device under "Storage Adapters".

As part of the migration you might have to 'resignature' your datastore(s). Watch out - this must be done on an unmounted datastore and cannot be reverted.

Hello Uwe,

You're famous on the Net as an HP SAN expert, thank you for responding.

I appreciate you clarifying the distinction between the HBA and the pNIC etc. I was going to get additional NIC boards and now I realize I don't have enough slots!! for 1 additional NIC board and 1 additional HBA...

Thank you, Tom

I forgot to ask -- what does 'resignature' the datastores mean??

Is this done within the SAN or within ESX??

I assume this reformats the datastores and that all my VMs should be backed up for restoration to newly created and discovered LUNs??

Thank you, Tom
