High Availability approaches for Cyrus

Murder rocks, IMO, well worth the learning curve of the setup.  If 
you're going to take the extra step of doing HA for your storage nodes, 
I think Murder makes even more sense.

We deployed our Murder cluster back in November and recently cut off 
access to our old Cyrus (single instance, multiple-spool) system and 6 
nodes with FC meta partitions and SATA storage partitions plus a single 
frontend absolutely rocks for our over 450,000 users (2.6m mailboxes). 
We don't do HA but Murder makes it easy to do if needed.
