Small form factor – 3.5²
Three configurations Internal, External and Hot Plug
Memory in Cassette functionality with AIT media
Overview
AIT 50-GB tape delivers
high capacity, high reliability, and high performance in a small form
factor. No bigger than a standard-sized hard disk drive, the AIT 50-GB
drive can be mounted in a half height drive bay. This allows the AIT
50-GB drive to be utilized in Compaq ProLiant Rack Density Servers where
drive height is a concern.
AIT 50GB Tape Drive, Customer benefits include:
High availability data protection – increases server up-time
Investment protection – backward read compatible
Faster Access with Memory in Cassette functionality

Mount Enclosure
Compatible with Compaq’s TA1000 AIT Tape Array (hot plug
configuration only)
Extends capacity and performance where DAT tape technology ends.
Advanced Metal Evaporated media aids in providing a tape drive
that needs minimal cleaning
Delivers 50-GB capacity at 6 MB/s in 3.5 in W x 1.6 in H size tape
drive
Disaster Recovery is now possible with DRTape.
Product Highlights
Disaster Recovery
The AIT 50-GB tape drive
has been improved with the added feature of DRTape. DRTape insures that
in case of a system failure, you will be able to restore your system
from a single tape.
What is Disaster Recovery: An AIT 50-GB Tape Drive that can:
Under Disaster Recovery (DR) situations, ID itself as a boot
device
Hold enough information to bring the system up for a DR restore
from tape
Is completely self contained in that it needs no other software or
CD’s to restore the system.
Note: DR not supported
on hot plug configuration
High Reliability
With optimized information
access features, the AIT 50-GB Advanced Intelligent Tape Drive extends
capacity and performance where DAT tape technology ends. AIT is designed
to handle the ongoing explosion of data storage requirements. Advanced
Metal Evaporated media aids in providing a tape drive that needs minimal
cleaning and virtually no head clogging. This drive has a mean time
before failure (MTBF) rating of 300,000 hours at a 30 percent duty
cycle. If the AIT 50-GB drive is used eight hours a day, seven days a
week (33 percent duty cycle), the heads are rated to last over 10 years!
Compression
Built-in Advanced Lossless
Data Compression (ALDC) hardware compression
Compatibility Testing
Compaq’s AIT 50-GB tape
drives are fully supported and compatible with Compaq Servers,
StorageWorks Enclosures and controllers. Compaq thoroughly tests
products with leading software and operating systems, including VERITAS
Backup Exec, CA ARCserve and Dantz Retrospect.
Manageability
Compaq makes managing your
tape device simple with the Compaq Insight Manager and Tape Storage
Management Console. These two tools help customers diagnose problems and
upgrade their firmware.
Advanced Intelligent
Tape (AIT) Technology
AIT drive employs a helical
scan recording style in which data tracks are written at an angle
relative to the edge of the tape. This provides higher density
recording, enabling Compaq customers to lower costs and increase
efficiency by storing more data on a single tape.
Memory-In-Cassette
AIT technology features
Memory-In-Cassette (MIC) a 64-Kb memory chip built into the data
cartridge which speeds access to your data. The MIC chip provides
sophisticated data access capability that allows users to load and
unload the tape at the mid-point, which helps in locating files in
seconds.
Backward Read Compatible
Backward read compatibility
with Digital TZS20, AIT 35 GB and all other first generation AIT tape
drives.
Mix and Match
Hot plug tape was designed
with reduced cost of ownership in mind. Now there is no need to purchase
a separate controller just for your tape drive. The hot plug
capabilities give our customers the ability to mix tape drives and hard
drives on the same SCSI bus.
Serviceability
Servicing your tape drive
has never been this easy. With hot plug tape, there are no tools
required and you do not have to power down your server. Simply pull out
your defective device and plug in your new one.
Big Power in a Small
Tape
Small but powerful,
Compaq’s AIT drive is equipped to handle the data deluge. The AIT 50-GB
drive delivers 50-GB capacity at 6 MB/s in 3.5 W x 1.6 H size tape
drive. More importantly, data access is rated at an average of 27-55
seconds to any point on a 755 feet/230 meter tape.
