LTO Ultrium 

Ultrium Linear Tape-Open (LTO) technology was developed jointly by Hewlett-

Packard (HP), IBM, and Seagate to enable data interchange among different LTO 

Ultrium tape drive vendors. LTO is an “open format” technology, which means that 

users have multiple sources of product and media. The “open” nature of LTO 

technology enables compatibility between the three different vendors.

The SL8500 supports the Ultrium Generation 2 and 3 LTO drives available

from HP, IBM, and Quantum. These drives use a single reel data cartridge with native 

transfer rates and capacities of up to 

■

35MB/s with capacities of 200 GB for LTO2 drives 

■

80 MB/s with capacities of 300 GB for LTO3 drives 

Super DLT 

The Super DLT (SDLT) is a standard for mid-range UNIX and Windows platforms. The 

SDLT 600 incorporates an advanced tape recording technology for high capacity tapes, 

up to 300 GB, with transfer rates of 36 MB/s.

Electronics Control Module

Each library contains an electronics control module. 

HBK Card

The HBK card contains flash memory and feature upgrade controls; it resides on a 

separate logic card within the control module. It contains the configuration, firmware 

versions, and features for the library.

Library configuration is retained on the flash memory card. This saves significant time 

in cases where an HBC card must be replaced, because the new card fetches the 

configuration from flash memory instead of requiring manual re-configuration by a 

service representative.
