Dedupe pool scale out to 5020 appliances.

We have six appliances (5020) with 32 TB each for total dedupe capacity of 192TB without requirement of replication. We can combine these appliances in following proposed patterns

A) Single 192TB global dedupe pool combining all six appliances
B) Two dedupe pools with 96TB each with combining 3 appliances for each pool.

Which one is better in terms of:

• Availabiliy (1+1)
• MTBF
• Backup Strategy (Planning, administration and management)
• Impact on backup environment if an appliance goes offline.
