I am implementing an SQL failover strategy for ms-sql 2k8, and am thinking of going with database mirroring. I've read that it's not intended for a large number of databases - however the article did not define 'large number'. I'd be looking to mirror around 70 databases.
Are there are limits to how many databases can/should be mirrored - is it solely dependent on bandwidth, or is it the effort of setting the mirroring up per database, or are there other issues?
