Monitoring copy data resources

Edit online

You can monitor the use and type of block storage resources in Copy Data.

You can get a complete breakdown of how each type of storage is used across the block storage environment.

Remote Relationships

Detailed information on remote relationships includes the type of relationship that exists between the source and target storage systems.
Synchronous relationship Synchronous relationship

Host writes are delayed until the source receives confirmation that the data is written to the target volume.

Asynchronous relationship Asynchronous relationship
Host writes can continue while data is being written to the target volume.
Where the type of volume is known, one of the following icons appears next to the volume in question.
Standard volumeStandard volume
A volume that is not thin-provisioned, compressed, encrypted, or encrypt-able.
Thin provisioned volumeThin provisioned volume
The volume is only allocated the required amount of server space as required.
Compressed volumeCompressed VDisk volume
Data is compressed as it is written to the VDisk.

Consistency Group

Details the status and type of the consistency group, and the number of relationships that exist in the group.

FlashCopy

Details the information on the last FlashCopy® operation between each source and target storage system.

VDisk Mirrors

Details the information on the volumes, pools, tiers, and synchronization status of the VDisk mirrors.

  • Identify target and source mirror disks at a glance.
  • Easily see the disks that are compressed, thin, or normal.

Replication Policies

Provides details about the replication policies such as name, ID, location 1 system, location 2 system, replication topology, RPO, and volume groups.

Volume Group Snapshots

Provides details about the volume groups snapshots such as name, state, safeguarded or not, associated volume group, time when snapshot created, expiration time, snapshot provisioned capacity(TB), and snapshot written capacity(%).

Safeguarded Copy

For DS8000, you can view the volumes that are backed up, the pool that the copies of a volume are written to, and the amount of capacity that is used to store the volume copies.

HyperSwap

Details the information on the status of the master and auxiliary volumes, pools, and tiers of the HyperSwap® relationships.

  • Quickly identify the master and auxiliary volumes and pools.
  • Drill down to see the amount of allocated disk for each volume.

Unprotected Volumes

Details the information on the volumes that are not backed up.
