Extended Hyper-V Replica–Windows Server 2012 R2


Hyper-V Replica allow you to perform asynchronous replication virtual machine from Data Center A to Data Center B. This feature allowed organization to has business continuity when VM running in Primary Site is down. When VM at Primary Site is down, customer can perform planned or unplanned failover which allow VM at Secondary Site to boot up and resume business operation.


With Windows 2012 R2 (Preview), Hyper-V Replica feature has improve to next level.


It allow us to

a) extend replication from Secondary Site to Third Site. Replica server at Secondary Site will forward information about changes that occur on the primary VM to a third server. After initiate planned or unplanned failover from the primary server to Replica server, the extended Replica server provides further business continuity protection.


b) change the frequency of replication. Previously we are limited to 5 min replication. Well a lot of customer make a lot of comment on this limit and would like to be shorter or longer. In this new version, this value is now configurable from 30 second, 5 min or 15 minute.
