I am looking for a NAS solution that can work well with an existing EMC DMX-4 SAN. A lot of data that needs to come off the premium disk in the SAN and onto lower cost NAS storage, but still needs to be readily accessible afterwards (hence the NAS).
Given the age of the SAN h/w, something newer would be preferable when it comes to the NAS, e.g. EMC Isilon NL series, NetApp equivalents, etc. I'm not looking to use DMX-era NAS, e.g. Celerra.
So, my questionS... :)....are:
1) Has anyone used any current NAS offerings with a DMX?
2) What did you find to be the best way of migrating existing data from the DMX to the NAS? (i.e. are there any tricks to it?)
3) How did you handle existing fibre-attached clients creating new block data landing on the SAN that should ideally go to the NAS, i.e. replication/removal?
