I noticed in the compatibility matrix for the EMC SRA's that in 5.0 and 5.1 the VNX SRA supports the EMC Celerra NX4 as well as the new VNX line of storage arrays. However then when you look at the version designed for SRM 5.5, the older storage arrays from the NX4 and earlier are dropped off the compatibility list, leaving only the newer VNX series arrays.
So do you think there will eventually be SRA's compatible with an NX4 for SRM 5.5 or am I limited to a maximum version of ESXi 5.1, vCenter 5.1, and SRM 5.1 as long as I have a perfectly working Celera NX4 at the DR site? Note the new VNX can still use Celerra replicator to the older arrays and thats exactly what I am doing. VNX at production to NX4 at DR site.
Or is there a better alternative to SRM? Should I start reading into the VMware replication appliance, veeam or some other solution?
