Abstract
The IBM Half High LTO Generation 3 SAS Tape Drive is the third-generation Linear Tape-Open (LTO) offering that delivers enterprise class capacity at an entry-level LTO Generation 3 price point. The drive offers an attractively priced entry offering into LTO technology for mid- to high-end System x servers requiring high-capacity, high-performance, and high-reliability tape solutions. These compact, half-high 5.25” internal and external form factor offerings leverage IBM copper-based technology to enable low-power, low-temperature integration into IBM System x tower servers, external IBM 1U rack-mount enclosures or for the external unit to be used as a standalone table top or shelf unit.
Using its onboard hardware data compression feature and assuming a 2:1 compression ratio, this drive can store up to 800 GB compressed per cartridge at a backup rate of up to 120 MBps. The LTO Generation 3 delivers strong performance with data transfers up to 60 MBps in native mode (216 GB/hr) and up to 120 MBps in compressed mode (432 GB/hr).
Introduction
The IBM Half High LTO Generation 3 SAS Tape Drive is the third-generation Linear Tape-Open (LTO) offering that delivers enterprise class capacity at an entry-level LTO Generation 3 price point. The drive offers an attractively priced entry offering into LTO technology for mid- to high-end System x servers requiring high-capacity, high-performance, and high-reliability tape solutions. These compact, half-high 5.25” internal and external form factor offerings leverage IBM copper-based technology to enable low-power, low-temperature integration into IBM System x tower servers, external IBM 1U rack-mount enclosures or for the external unit to be used as a standalone table top or shelf unit.
Using its onboard hardware data compression feature and assuming a 2:1 compression ratio, this drive can store up to 800 GB compressed per cartridge at a backup rate of up to 160 MBps. The LTO Generation 3 delivers strong performance with data transfers up to 80 MBps in native mode (288 GB/hr) and up to 160 MBps in compressed mode (576 GB/hr).
