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.
