How to set up a hot-backup, enclosure-to-enclosure or RAID-to-RAID replication using brocade 200E

One of my client requires that the present RAID BOX (Overland Ultamus 1200) connected to a Brocade 200E SAN switch should be replicated to another such box connected to the same switch in hot-backup mode.
Is it possible to achieve this without the help of another tool (like Veritas or Netapps' ReplicatorX etc) by just using in-built features of Brocade's FibreOS (may be N_port aliasing or something)

A SAN switch can't do this since even for a write operation there are both reads and writes going on under the fibre channel protocol and which storage box would you read the status from? Doesn't look like your SAN storage box has replication either (some do but the licence is *very* expensive) so you're going to have to replicate to another storage box at the OS level.

Of course when I say it has to be done at the software level that's not discounting such products as LeftHand Networks SAN/iQ or Datacore's SANsymphony which can run on seperate boxes than your application servers rather than do it on the application servers themselves. Come to think of it if you're mirroring at the application level you can probably just setup software mirroring under the OS rather than buying seperate add-on software.

Thanks Andyalder for clarification. You mean even the expensive SAN driectors don't have this feature
