Storage Replication in Windows Server vNext

Gavin Payne


One of the most interesting features for me that’s been announced in the next version of Windows Server so far is Storage Replication.

Microsoft’s definition in a blog post from last year is below, I’ve highlighted the parts that are I think could make this a disruptive new feature.

Storage Replica enables storage-agnostic, block-level, synchronous replication between clusters or servers for disaster recovery, as well as stretching of a failover cluster for high availability. Synchronous replication enables mirroring of data in physical sites with crash-consistent volumes ensuring zero data loss at the file system level. Asynchronous replication allows site extension beyond metropolitan ranges with the possibility of data loss.

The source article I read is available here.

I’m sure this feature will have restrictions and limitations, but I see this potentially as a way of:

  • Providing multi-site high availability without Availability Groups or infrastructure-level storage replication
  • Deploying failover clusters in cloud platforms (Azure etc)


Time will tell if any of these become possible……
