Can I add ActiveRAID to my existing Xsan Installation?

The ActiveRAID is compatible with Xsan and Xsan2 and will seamlessly integrate into an
existing Infrastructure. The ActiveRAID will co-exist with Apple Xserve RAID systems in a 2Gb
or 4Gb Fibre Channel environment. It should be noted that for best performance the Fibre Channel fabric
should be upgraded to 4Gb/s.
