What’s New in the VMware vSphere 6.0 Platform

VMware vSphere Replication Enhancements

VMware vSphere Replication™, the VMware proprietary replication engine, provides data protection and disaster

recovery for the vSphere platform by replicating virtual machines within the same site and across sites. It is

tightly integrated with vSphere and is managed using vSphere Web Client. It is included with vSphere Essentials

PlusKitandlatereditionsofvSphere.Multiplepointsintimerecoverycanbeenabledtoprovideasmanyas

24 recovery points for a replicated virtual machine. vSphere Replication is used as a standalone solution and as a

replication engine for VMware vCenter Site Recovery Manager™ and VMware vCloud® Air™ Disaster Recovery.

The recovery point objective (RPO) can be set on a per–virtual machine basis and can range from 15 minutes to

24 hours. After initial synchronization between the source and the target locations, only changes to the virtual

machines are replicated, enabling vSphere Replication to minimize network bandwidth consumption. New to

vSphere Replication in vSphere 6.0 to further improve eciency is the option to compress replicated data as it is

sent across the network.

It is now possible to easily isolate network trac associated with vSphere Replication. This enables vSphere

administrators to control bandwidth by conﬁguring more than one network interface card in a vSphere Replication

virtual appliance and by using vSphere Network I/O Control to separate network trac. The result is improved

performance and security.

Enhancements have been made to the way vSphere Replication performs a full synchronization. Previous

versions of vSphere Replication requested and compared remote checksums with local checksums to

determine the regions of a virtual disk that had to be replicated. With some storage platforms and vSphere 6.0,

vSphere Replication can query vSphere for storage allocation information, to reduce the amount of time and

network bandwidth required to perform a full synchronization.

vSphere Replication is fully compatible with VMware vSphere Storage vMotion® at both the source and target

locations. Prior to vSphere 6.0, moving a replica at the target location required vSphere Replication to perform a

full synchronization. With vSphere 6.0, migrating a replica with vSphere Storage vMotion no longer requires this.

That makes it much easier to balance storage utilization with vSphere Storage vMotion and VMware vSphere

Storage DRS™ while avoiding RPO violations.

Improvements have also been made to VMware Tools for Linux virtual machines. With some Linux OSs,

VMware Tools features the ability to quiesce the guest OS during replication and backup operations.

vSphere Replication can utilize this new functionality to enable ﬁle system–consistent recovery of Linux

virtual machines.
