TSM Tape Media Detail Table
The following table is displayed for reports that have a TSM host group scope.
Node Name | Name of the TSM node/server |
File Space Name | Name of the TSM file space that was copied to tape |
Copy Type | Type of transfer to tape |
Storage Pool | The TSM Storage Pool name |
# of Files in Stg Pool | Number of files in the TSM storage pool for this node |
Stg Pool Phy MBytes | Amount of data in the TSM storage pool for this node |
Stg Pool Log MBytes | Size of the TSM storage pool log file |
Estimated Capacity Notes
Every time tape data is captured, Storage Viewer recalculates the estimated tape capacity for the tape media type and volume pool combination. It takes into consideration the written KBs for the media type and volume pool for full tapes and then stores the average as the estimated tape capacity. Initially, when there is not enough data captured, this value may look low compared to the capacity stated by the vendor. Over time, the estimated capacity improves to the actual number of KBs that is being written to the tapes. Note that the amount of data that fits on the tapes differs based on the compression algorithm used and the type of data that is being backed up, which results in different compression ratios.
