About 8TB of data was transfered from eight servers (~1TB/server). After about 10h transfers started to fail because the disks on the movers were filled. At that time 6.5 TB were transfered.
FGST servers used | 8 |
total number of files | 3359 |
total size | 8.09 TiB |
transfers failed | 534 |
The average transfer rate from disk to tape was about 78MB/s. Only one tape drive at a time was allowed for writing
and therefore files cold not be copied fas enough to tape and the cache disks filled up.

While the transfers were running the network IO and (for some time) the disk IO on the two HPSS movers were recorded.
The HPSS instance has two disk arrays that are accessed by both movers and show up as devices sdc and sdd.
The disk IO was not monitored during the first 7:30 hours therefore no data are shown for this time in the disk IO plots.
