I think about strategy for creating volumes for VMware 5.5
In our envirorment we have 2 storage arrays of equallogic 18TB each in concept 1 array is to store replica and 1 to work .
What should be strategy to place virtual machines storage on datastores(volumes).
1) separate data and operating system volumes of VM to different datastores (array volumes) - for different replication schedules?
2) create one 2TB datastore and place whole VM storage in it ? - implies replication only for disaster/fast recovery of full array/lun
3) create one datastore for each VM - so be able to recover single VM from snapshot
4) any other strategy to apply ?
