Re: Clarion CX500 or Sun StorEdge 6920 Storage solution

I would go with the Clariion over the Sun box. While the Sun box has the advantage of being able to virtualize other companies' storage, it begs the question, "Why would you want to?". Also, Sun storage has a tradition of being terrible, especially early revs, and this is a rev 1 box at the moment. Beyond that, Sun's support for non- Solaris OSes is usually less than ideal, while EMC specializes in that.

As far as the replication goes, data guard has the advantage that it won't propagate corruption to the far side. Storage based replication has the advantage that it can be synchronous even when the database is down on the far side, with no host CPU involvement. Pick your poison.....

Thanks,
Matt
