iSCSI SAN

[kresten]

Hello proxmox users.

I'm going to setup a proxmox cluster with all the VM's stored on a EMC san, and i would like a little help with the basic setup.

The EMC san has two storage processors with 4 iSCSI ports on each.
Im going to connect four servers to the SAN and each of the servers have a qlogic iSCSI card with two ports on each card.

So first question i wanna ask is - how would you recommend to do the network/IP setup ?
My idea is to connect the servers directly to the SAN - like the following
server1 port 1 - SPA port 1
server1 port 2 - SPB port 1
server2 port 1 - SPA port 2
server2 port 2 - SPB port 2
and so on.

Furthermore - is it possible to use all four servers with only 1 LUN?

And how would i configure this in proxmox ?

thanks in advance

Hello tom

Thank you - This will help me get the multipath working

I'm still in doubt weather i need one shared LUN for all 4 servers, or 1 LUN for each server ?

thanks

there is no restriction on the proxmox ve side, you can configure whatever you want.
