VVols
Storage Manager supports the VMware virtual volumes (VVols) framework. VMware administrators use vCenter to create
virtual machines and VVols. You must be connected to a Data Collector Managerto use VVols.
When properly configured, you can use Storage Manager to manage and view VVols, storage containers, datastores, and other
aspects of VMware infrastructure.

Disaster Recovery Features
Storage Manager allows you to plan and implement a disaster recovery strategy for your Storage Center volumes.
Remote Storage Centers and Quality of Service
Storage Centers can be connected to each other by Fibre Channel or iSCSI to allow data to be copied between them. Storage
Manager allows you to coordinate connected Storage Centers to distribute copies of your data to remote sites, ensuring that
your data is protected and available even if one site goes down.
Replication Quality of Service (QoS) definitions allow you to control when and how much bandwidth is used for communication
between Storage Centers.

Replications and Live Volumes
As part of an overall Disaster Recovery Plan, replication copies volume data from one managed storage system to another
managed storage system to safeguard data against local or regional data threats. If the source storage system or source site
becomes unavailable, you can activate the destination volume to regain access to your data.
A Live Volume is a pair of replicating volumes that can be mapped and active at the same time. Similar to a conventional
replication, the primary (source) volume on a primary storage system replicates to a secondary (destination) volume on a
secondary storage system. However, both the primary volume and secondary volume can accept writes.

Disaster Recovery Activation
If you configure replications, Live Volumes, or both, you can use Storage Manager to prepare for and perform disaster recovery.
Storage Manager allows you to predefine your disaster recovery plans, including which servers the recovery volumes will be
mapped to. In the event of a real disaster, you can use Storage Manager to activate your disaster recovery plans, making your
data available to the resources that need it as soon as possible.
