Connect MSA 2312fc G2 to 4 SAN switch

[Osama Odeh_1]

we have MSA 2312fc G2
can we connect this storage to two qlogic SAN switches(using only 1 port from each controller A and B for MSA2000 left ports
...
and connect another two cisco mds (HP BLade SAN switches) to the same storage by using the the right two ports on MSA controllers for HP blade servers access

Thanks in ADV

Practically it is possible. But you must have 2 ports on each host and connect to both the SAN switches to achieve Controller redundancy.

but what happend if one controller failed

[Uwe Zessin]

Then the other controller should take over the management of the vdisk and its volumes.

Best practice is to have one port from each controller should go to host, which will provide you path level and controller level redundancy.


Please assign points if this help you.

can we present the same volume to all hosts on connected to the four san switches without probelm for redundancy if each host has two hba connectd to two san switch.

[Bhavnish Kamboj (BK)]

If you are presenting the same volume to more than one independent hosts (means not in cluster) then you will corrupt your data. As one Volume can hold one Host Signature at a time.

I know that, but in our case all servers are esx servers so no problem for volume signiture signiture

[Bhavnish Kamboj (BK)]

Yes, in that you must assign all volumes to all ESX hosts and make sure they retain same lun id while assigning as it will help you in doing failover of a VM to another ESX.
