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 congure replications, Live Volumes, or both, you can use Storage Manager to prepare for and perform disaster recovery.
Storage Manager allows you to predene 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.

Monitoring and Reporting Features
Storage Manager provides the following reporting and monitoring features.
Threshold Alerts
The Threshold Alerts feature provides centralized administration and monitoring of threshold alert denitions. The types of usage
metrics that can be monitored are IO, storage, and replication usage.
Storage Manager collects the usage data from the managed
Storage Centers. Storage objects on the Storage Centers are assigned to threshold denitions and each threshold denition contains
one or more threshold values. When the value of a monitored metric reaches a threshold value, an alert occurs.

Reports
The Reports feature allows a user to view Storage Center and Chargeback reports generated by Storage Manager. Storage Manager
can be congured to generate the reports on a scheduled basis.

Chargeback
The Chargeback feature monitors storage consumption and calculates data storage operating costs. Chargeback can be congured
to charge for storage based on the amount of allocated space or the amount of congured space. When cost is based on allocated
