Hi, I use a Benchmark DLT tape drive to backup data on my DELL PowerEdge 2650 system; syslog says:
Apr 20 09:09:02 gwdu111 /kernel: sa0 at ahc0 bus 0 target 6 lun 0 Apr 20 09:09:02 gwdu111 /kernel: sa0: <BNCHMARK VS640 5032> Removable Sequential Access SCSI-2 device Apr 20 09:09:02 gwdu111 /kernel: sa0: 20.000MB/s transfers (10.000MHz, offset 15, 16bit) The problem I see is that data flow is not steadily streaming; the tape drive is operating in start-stop-mode. Disk speed does not seem to be the problem, e.g.: gwdu111# dd if=/home/local2/ftp/pub/FreeBSD/3.3-RELEASE.iso of=/dev/null bs=8k 82401+0 records in 82401+0 records out 675028992 bytes transferred in 14.670024 secs (46014170 bytes/sec) What can I do to improve the situation? Any ideas are very welcome. Thanks in advance!
