Performance of the Tape Drive
Performance of the Tape Drive
The CT9840-1/CT9840FC-1, 5259, N1521A, CT9841FC-1, and M8503 tape drives
store and share information reliably and quickly. They offer the speed, capacity, and
access demanded by today’s storage-intensive applications and active users.
Mainframe-class reliability allows continuous and confident operation. Utilize space
more efficiently by attaching more drives to a new or existing library.
The subsystems have these characteristics:
•
Faster backup and restore operations:
°
Move or retrieve data with simultaneous read or write to each controller
transport unit. First access to data averages 8 seconds for the CT9840-
1/CT9840FC-1/CT9841FC-1 tape drive and 70 seconds for 5259 tape drive.
•
Store more data:
°
CT9840-1/CT9840FC-1 tape drive: Each cartridge holds up to 20 GB
uncompressed (60 GB with compression).
°
5259 tape drive: Each cartridge holds up to 110 GB uncompressed (220 GB
with compression).
°
N1521A tape drive: Each cartridge holds up to 400 GB (2:1 compression).
°
M8503 tape drive: Each cartridge holds up to 800 GB (2:1 compression).
°
CT9841FC-1 tape drive. Each cartridge holds up to 40 GB uncompressed
(120 GB with compression)
•
Flexible. Mix combination of additional drives to new or existing libraries.
°
Attach a combination of additional drives to new or existing libraries.
Robotic Cartridge Loader
The tape library holds from 168 to 630 tape cartridges. The robot contained in the
CTL700 tape library is responsible for loading and unloading the tape cartridges into
the tape drives as tapes are requested by the system.
