Enhanced VMware NSX Integration
VMware NSX 6.2 makes it possible to extend your virtual network across multiple vcenter servers and lets you work with a seconday NSX manager. This will give you much more fexibility when implementing SRM into your enviroment.
Storage Policy-based Protection Groups
Datastores that are protected by SRM will have a tag and this tag can be assigned to a virtual machine. If a virtual machine receives this tag it will be automatically moved to the linked datastore trough a storage vmotion. Once on the datastore it will be picked-up by SRM and added to the protection plan.
To remove a virtual machine from the protection plan simply remove the tag.
Stretched Storage Support
With stretched storage support, SRM 6.1 now offers the integration of a stretched cluster. This means that in addition to plans for disaster recovery, you can now also create plans for disaster avoidance and mobility.
