Block storage copy data resources

See information about the capacity, space usage, and relationships of block storage systems and how the copy data resources are used for primary and copied data.

The detailed information on the different ways a storage system is involved in remote relationships and how copying data uses resources is shown in the following tabs:

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 beside the volume in question.
Standard volume Standard volume
A volume that is not thin-provisioned, compressed, encrypted, or encrypt-able.
Thin provisioned volume Thin provisioned volume
The volume is only allocated the required amount of server space as required.
Compressed volume Compressed VDisk volume
Data is compressed as it is written to the VDisk.

Name
Indicates the name of the unprotected volume.
Pool
Storage System
Status
Copy ID
Indicates the identifier of the volume copy. For volumes in a mirrored volume relationship, the copy ID distinguishes between the primary and secondary volume copies.
Acknowledged
ID
Unique ID
Capacity (GiB)
Indicates the capacity that is committed to the volume, which might include overhead capacity if the disks for the pool are not formatted. For thin-provisioned volumes, capacity represents provisioned capacity of the volume. For XIV system and IBM Storage Accalerate, capacity represents physical or 'hard' capacity of the volume.
Thin Provisioned
Used Capacity (%)
Indicates the percentage of the capacity of the volume that is physically allocated. The capacity that is physically allocated to a thin-provisioned volume might be less than the capacity of the volume. For compressed or deduplicated volumes, this value never reaches 100% even when the provisioned capacity of the volume is fully used.
Threat Detection Timestamp
Used Capacity (GiB)
Indicates the capacity that is used by the volumes. For thin-provisioned volumes, the capacity that is used by the volumes might be less than the provisioned capacity of the volume.
Available Capacity (GiB)
Virtual Volume ID
Written Capacity (%)
Indicates the percentage of volume capacity that is written by the assigned the host. The physical and virtual allocation percentages are different when the data reduction reduces the that is required to store the written data. Available for FlashSystem A9000, FlashSystem A9000R, XIV storage systems, and resources that run IBM Storage Virtualize.
Written Capacity (GiB)
The amount of data that is written from the assigned hosts to the volume before that data is compressed or deduplicated.

IP Replication

IP Replication tab details the information on the aggregated IP replication workload between the viewed storage system and any remote partner storage system. The three charts on the tab provide you the information on the following metrics.

IP Replication Latency

IP Replication Latency: Average round-trip time for the IP partnership link since the last statistics collection period.

The following information show about the Replication Policies.

Name

Indicates the name of the volume group.

State

The state of the fileset. Valid values are listed.

Volume group

A volume group is a container for managing a set of related volumes as a single object. The volume group provides consistency across all volumes in the group. View the information that is shown about volumes in block storage systems.

The status displays the number of days, hour, minutes left for the service to expire.

Provisioned Capacity

A thin provisioned volume is a volume with a provisioned capacity that is different from its real capacity.
