Managing Virtual Volumes With Storage Manager

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.

Remote Data Collector

A remote Data Collector is installed at a remote site and connected to the primary Data Collector to provide access to disaster recovery

options when the primary Data Collector is unavailable. In the event that the primary Data Collector is down, you can connect to the

remote Data Collector at another site to perform Disaster Recovery.
