Ah, I see now. Technically, you'd want establish DRBD synchronisation between the SAN at your A site and the SAN at the B site. Manual failover would include making SAN B Primary. Now, if said SANs are proprietary all-in-one products, your possibilities for adding DRBD to it may be severely limited. Your SAN vendor may or may not offer a cross-site synchronisation of their own. HTH, Felix
