I've set up a 3 node cluster with Windows Server 2008 R2. I need to connect to these nodes a lot of lun (18 LUN on each node; not my decision... :( ). After digging a while with iSCSI Initiator configuration I found that I reach the 256 connections limit of iSCSI Initiator, so I decided to do a "fine tuning"...
Every node has 4NICs dedicated to iSCSI connection. Using the HP MPIO DSM, every LUN connection generates 16 connection (4 NIC * 4 SAN Nodes)
So I decided to use 4 NIC to connect the "most demanding" LUN, and only 2 NIC on each less used LUN. Doing so I can stay under 256 connection (actually I reach 246 connection).
The problem raises when I need to restart one of the server. After restarting the iSCSI configuration seems partially lost: even the "less demanding" LUN are connected to the server with 4 NICs so I'm again over 256 connections...
Anyone has ever did something like that and can advise me? (I thought about using less than 4 NIC for each LUN, but I can do that)
Thanks for any help
