We have two identical RAID servers on which we were running v7 in a multipath configuration without the Active-Active module. Once we installed the
Active-Active module we could no longer get multipathing to work.

The RAID servers each have 2 x 1GbE NICs and 2 x 10GbE NICs. Each of the 10GbE interfaces has a virtual IP for connecting to our XenServer farm. One of the 1GbE interfaces is used purely for replication and the other 1GbE as the management port.

Is it possible to have Active-Active setup and to have multipathing with just the 4 NICs? Or are we going to have to purchase another dual port 10GbE card for each RAID server?

I had a look at the http://www.open-e.com/site_media/dow...I_Failover.pdf guide and it seems to list 6 NICs as being needed. I just want to confirm this is the case before going ahead.

Thanks for any advice.
