Abstract
The IBM Half High LTO Gen 4 SAS Tape Drive is the fourth-generation Linear Tape-Open (LTO) offering introducing larger storage capacities, increased performance, and advanced security features to effectively meet the demanding backup, archival and regulatory compliance requirements of your System x environments.
The IBM Half High LTO Gen 4 SAS Tape Drive is an excellent tape storage solution for businesses requiring backup or low-cost, real-time archiving of their data within a small window of time. This fourth generation drive provides up to twice the storage capacity, up to 1.6 TB with 2:1 compression, and provides up to a 50% performance increase, up to 240 MBps (864 GB/hr) with 2:1 compression, over the preceding LTO 3 half height technology. This enterprise data protection offering is available in a 5.25-inch half-height internal form factor for integration into IBM System x tower servers and external IBM 1U rack-mount enclosures or a half-height external unit for stand-alone table top or rack shelf applications.

Internal use
The following components are needed:
- A supported SAS host bus adapter installed in the server (see Table 3)
- An available 5.25-inch, half-height bay
External use
If the internal tape drive is to be installed in an external enclosure, the following components are needed. We describe these enclosures and the enclosure adapter kit in the "Supported enclosures and enclosure kit" section.
- A supported SAS host bus adapter installed in the server (see Table 3)
- A supported external enclosure:
