Assign same IP range to another interface in same segment ,for iscsi network

[tbaror]

Hello,

I would like to create Xen platform iSCSI based, using FreeNAS as storage with 3 10g interfaces assigned to each LUN.
The issue is if can't assign for the 3 10g interfaces same IP, I must do routable iSCSI network , and from reading little bit on it, it's not the most recommended to route iSCSI network.
Any advice regarding that subject will be appreciated.
Thanks

You're going to have to go with a different subnet if you want this to work right. Trying to put all three interfaces on the same subnet is going to cause issues. I tried it out of curiosity on my own network and it did some strange things including causing the whole network to crash a couple of times.

Each of the three interfaces would need to get a different subnet. It would allow for the most bandwidth, assuming you have it in your drives. I personally have an iSCSI network (10Gb), a general "storage" network (10Gb), an internet network (1Gb) and a management network (1Gb).
