Backup and Tape Subsystems

Notes:

■ Due to the bandwidth requirements of video, best results are achieved by dedicating an array to

a system. If you are using lower data rates or less complicated programs than our test programs,

you can have more than one system access the same array, but this is not ideal. One array per

CPU is recommended for optimal performance.

■ By adding more drives and lower data rates, you can add more systems.

■ ATTO FibreBridge worked well for attaching legacy SCSI devices to the Fibre Channel loop.

■ If you open a program from a volume where you have read only privileges, you will need to do

a “Save as” and save the program to a volume where you have write access. We do not

recommend that more than one user is working on a program at any given time.

■ When Mastering to tape it is critical that no other system on the loop shuts down or reboots and

that you have Read/write exclusive privileges.

The above conﬁgurations have been tested by Media 100 and ATTO. Any deviation from the above

could result is problems with the network, down time, and stability issues.

Backup and Tape Subsystems

Tape backup systems have always been a good idea, but the speed and cost of tape mechanisms

have been a deterrent. Since there have been some improvements and we have received questions,

we have looked at some products recently. Because of the increased speed and ﬂexibility, these

products can be a great investment and used for off-line storage.

■ The Cybernetics CY-8000-ASP — a very ﬂexible dual AIT drive:

 From the front panel you can select various operation modes.

 It is capable of striping two AIT tapes for faster backups.

 It allows mirroring so that you have two copies of your backup if you want to archive or

store one off site.

 It can be set to cascade mode so when one tape is full it automatically continues the backup

on the second tape so you do not have to be available to swap tapes.

 It will also work in independent mode as two separate tape drives. There is also an off-line

mode which allows you to make duplicate tapes for off-site storage of data exchange.

■ The Exabyte 210 Automated 8mm Tape Library

 A durable robotic system that holds up to 10 20GB (uncompressed) data cartridges.

 Fully compatible with Retrospect backup software and is extremely reliable.

 It is available in a tower or rack mount style.

■ The Exabyte EZ-17 is smaller desktop model that accommodates one Exabyte Mammoth tape

drive and 7 Exatape™ AME data cartridges (20GB uncompressed) in a removable data

cartridge magazine.

■ The Exabyte Mammoth 8mm Tape Drive is a single low-cost solution.
