Scale Computing latest HC6 release features built-in Remote Disaster Recovery to allow users to set up continuous replication on a VM by VM basis between two HC3 clusters with space-efficient snapshot technology replicating to a secondary site, tracking only the blocks unique to each manual or automatic snapshot and sending the changed blocks. Testing a DR infrastructure plan is now as simple as cloning a snapshot on the target cluster and starting a VM with no disruption to ongoing replication. In case of disaster, users can simply “clone” a snapshot on the target cluster for the manual failover of a VM that is immediately bootable or simply replicate changed data at a DR site back to the primary site for simple failback.
Marco gives a great overview of the Scale Computing solution from Virtualization Field Day 4. This is a great solution if you’re looking at deploying virtualization in your SMB.
