Additional Information 
High performance 
The extremely high performance of the 9710 ACS Tape Cartridge Silo 
Subsystem storage subsystem is possible through the use of the Compaq 
fiber channel tape controller (T16/3216), state of the art DLT technology, 
and Digital Lempel-Ziv (DLZ) high efficiency data compression. 
Burst data transfer rates of up to 3.0MB/sec (2:1 data compression is 
assumed) are possible dependent upon systems type and configuration. 
The 9710ACS Tape Cartridge Silo Subsystem provides true production 
system level tape storage performance for Compaq NonStop servers. 
High capacity 
Utilizing the CompacTape IV DLT tape cartridge, storage capacities  
of 20GB native or 40GB compressed are available on a single data 
cartridge. On-line backup of up to 23.52TB is possible with the optional 
588 cartridge expansion door. 
Media interchangeability 
The 9710ACS Tape Cartridge Silo Subsystem can exchange data with 
other DLT systems via currently available DLT tape media. Data can be 
interchanged on the standard CompacTape IV, CompacTape III, or 
CompacTape IIIXT DLT tape cartridges. 
High reliability 
Data integrity is unequaled by any other cartridge tape system. Critical 
reliability specifications include a head life of 10,000 hours and high tape 
passes. Media suppliers provide Media reliability and warranties, not 
Compaq.
