# VTS Capacity

The VTS Capacity attributes provide utilization information about the physical tapes utilized by a virtual tape server (VTS).

Active Data TB: The number of bytes, in terabytes, of data being managed by this VTS.

Active Logical Volumes(1000): The number of logical volumes managed by the VTS that contains active data. This data is reported in units of 1000.

Empty Physical Volumes: The number of empty physical cartridges available for use by the VTS.

Empty Volume Free Space GB: The estimated storage capacity in gigabytes, available on the empty 3590 cartridges managed by the VTS.

ESCON® Channels Connected: The number of ESCON channels connected to this VTS.

Host Channel Activity GB: The total, READ + WRITE, number of gigabytes (1,073,741,824) processed by the MVS™ host channels to the virtual tape volumes associated with the VTS.

Host Channel GB Read: The number of gigabytes (1,073,741,824) read by the MVS host channels from the virtual tape volumes associated with the VTS.

Host Channel GB Written: The number of gigabytes (1,073,741,824) written by the MVS host channels to the virtual tape volumes associated with the VTS.

Host Channel Read Percent: The percentage of all host channel byte movement that was the result of a read request by the MVS host channels from the virtual tape volumes associated with the VTS.

Managed System: The SMS name of this system.

Physical Tape GB Read: The number of gigabytes (1,073,741,824) read by the MVS host channels from the virtual tape volumes associated with the VTS.

Physical Tape GB Written: The number of gigabytes (1,073,741,824) written by the virtual tape server to the physical tape drives.

Physical Tape Read Percent: The percentage of all physical tape byte movement that was the result of a read request by the VTS.

Reclaim Threshold Percentage: The percentage identified when a physical cartridge is made available for reclamation. When the percentage of active data falls below the reclaim threshold, the physical volume is available to go through reclamation.

- DISTRIBUTED VTS: A VTS that is part of a peer-to-peer VTS environment, but has not been designated for user interface commands.
- DISTRIBUTED USER INTERFACE VTS: A VTS this is part of a peer-to-peer VTS environment, and has been designated for user interface commands.
- COMPOSITE VTS : The logical view of a peer-to-peer VTS environment.
- NOT APPLICABLE: The library type attribute does not apply to TS7700 resources.

VTS Name: The name of the VTS as assigned via the ISMF panels.
