SQL 2008 R2 p2p replication alternate -


the requirement. establish 3 global data centers (sites) , direct users closest site based on cisco global site selector. if site 1 goes down site 1 traffic direct site 2. if user site 1 travels site 2 or 3 should able access information entered. data should same across data centers, in near real-time. should able add new data center.

the issue: have existing database needs replicated 3 sites , have exact same data. thought use sql 2008 peer-to-peer replication no go due method not supporting identity columns.

what other replication technologies exist keep 3+ sql server 2008 databases in sync across global data centers? 3rd party tools? block replication? remote clustering?

i have used merge replication purpose results. http://msdn.microsoft.com/en-us/library/ms151329.aspx

the largest system ever managed 11 separate locations having on on-site server.

note used individual locations accessed shared db if lines ever went down still operate well. how translates off-site data centers don't know.

we set autonumber increment 100 , set seed value each location differently.
