I'm looking into various SAN offerings to come up with a backup plan for my company.
We have two offices, interconnected by a T1 MPLS line. 500gb or so at the main office and 300gb or so at the branch.
Currently both backup sets are backed up independantly using an LTO3 drive at each location.
What I would like to do is backup the data to a SAN and have it replicate to the other site. that way I have all my main office data at the branch and vice versa.
Equallogics looks awesome, built in replication, and volume snapshot capability. only downfall is the cost.
Option 2 is a pair of MD3000i SAN's, would require the use of double take or DFS to replicate the data over the wire and would not be as robust as the EQL.
I've looked at HP LeftHand products, replication requires very low latency between sites, and the fact that each node only has a single controller is concerning.
Any other suggestions all?
