Hi, My company currenty uses an EMX CX-700 SAN to host all our SQL server clusters. After some aggravation it now works very well - so I'm a happy DBA. [8D] So along comes my boss and says we are going to open another data centre, in another country, and it's going to mirror what we have in the UK. The head begins to ache... Ok so this is for DR purposes only and it all the hardware will be identical. I only have a live database at one site at a time - no load balancing. EMC have recommended we use MirrorView, which is there product for syncing 2 SAN's byte by byte at disk level. In principle it sounds very clever (and complicated) but not unreasonable. Has anyone got any experinces they can share with me of this product? I have reservations, particulary with DR recovery and the files being in a attachable state. I'm getting a demo in a couple of weeks - so this is just for background work really. Personally being a DBA I'm happy with log shipping - but this wouldn't appear to be fancy enough for some.... Many thanks!
