Reserved LUN Pool CommandsNote: To protect your replication sessions from being terminated (if nofree reserved LUNs were available in the pool), the number of reservedLUNs in the pool should always be two times the number of sourceLUNs.Example for optimizing for capacityThe goal is to create 1 session each on 100 source LUNs, where thelargest is 100 GB, and the smallest is 50 GB:Basis of source LUN size: 50 GBEstimated change rate: 20% = 10 GBMinimum number of reserved LUNs: 100Extra reserved LUNs to ensure that larger source LUNs get enoughreserved LUN space: 2 x minimumThis would translate to 200 reserved LUNs that are each 10 GBExample for optimizing for max source LUNsThe goal is to create 4 sessions each on 100 source LUNs, where thelargest is 100 GB, and the smallest is 50 GB:Basis of source LUN size: 1 TBEstimated change rate: 4 x 20% = 800 GBMinimum number of reserved LUNs = 100Extra reserved LUNs to ensure that larger source LUNs get enoughreserved LUN space: + 20% = 20 extra reserved LUNsThis would translate to 120 Reserved LUNs that are each 80 GB356 EMC Navisphere Command Line Interface (CLI) Reference
