Two tape dirves are currently used for backup of the PHAS departmental servers.

1. StorageTek L20 tape library attached to one Adaptec 29160 SCSI controller.  It currently contains 1 HP LTO2 tape drive, sync at 160MB/sec, 68-pin HD SE LVD SCSI connector Ultrium-460: 200/400Gb, ?MB Buffer, Sustained rate 15 MB/s (54 GB/hr) native, 30 MB/s (108 GB/hr) compressed.

2. HP Ultrium-215 (uses tapes C7979A) Shares an Adaptec 29160 SCSI controller with a SCSI hard drive.  Sync at 80MB/sec, 68-pin HD LVDS connector Ultrium-215: 100/200Gb, 16MB Buffer, Sustained rate 7.5 MB/s (27 GB/hr) native, 15 MB/s (54 GB/hr) compressed, Burst rate of 80MB/s, data rate-matching range 6-7.5MB/s.

This drive is used to backup the NetVault tape indexes.  These indexes contain info about what is backed up to which tape drive.  These tapes are labelled NV-DBASE-XXX, where XXX is a number from 000 to 999.

3. HP DAT-40i tape drive , This drive is no longer used for backups.  Specs:  40GB,   21.6 GB/hr, 6MB/sec   (compressed 2:1).

I keep some tapes archived in the Hebb Building in Room 5D (basement), in a steel cabinet.  The key is on the set with the large aluminum Fob marked "HEBB PODIUM / TAPE STORAGE".
