The Half High LTO-7 Tape Drive Feature
This section describes the 7226 Model 1U3 Storage Device Enclosure Features #8441 and #8446, the Half High LTO-7 Tape
Drives. It describes operator controls and indicator LEDs, gives instructions for loading and unloading a tape cartridge, and
tells how to clean the tape drive. These tape drives are streaming tape storage devices that use LTO technology.

LTO Features
The IBM LTO-7 Tape Drive is a high-performance, high-capacity data-storage device that is designed to backup and restore
open systems applications. These files can include multimedia, imaging, transaction processing, large databases, and other
storage-intensive applications. Each tape cartridge can store up to 6 TB of data (uncompressed), or up to 15 TB of data
(compressed), assuming a 2.5 to 1 compression ratio. It is the seventh generation in the Ultrium series of products, and is
available with a Serial Attached SCSI interface (SAS) or Fibre Channel interface. This model incorporates the Linear Tape-Open
(LTO) IBM Ultrium 7 Half-High Tape Drive.
Note: The actual capacity varies depending on the application, the type of data, and the tape cartridge. 6 TB is typical and 15
TB is possible when the Data Compression setting is activated. The default setting of Data Compression is controlled by the
host system. The user and the application software can control the activation or deactivation of the data compression setting.
The drive can typically achieve a 2.5:1 compression ratio.
The LTO half high tape drive features:
Single port 6 Gbps Serial Attached Small Computer Systems Interface (SAS); or single port 8 Gbps Fibre Channel
Interface. (Auto-negotiation to lower speeds is assumed.)
Half height form factor
Native storage capacity of 6 TB per cartridge (15 TB at 2.5:1 compression)
Maximum native data transfer rate of up to 300 MB per second
Burst data transfer rate:
SAS 600 MB per second
FC 800 MB per second
1024 MB read-and-write cache
Support for encryption on Ultrium 5, 6, and 7 tape cartridges
Single Character Display (SCD) operator panel
Ready and Fault status LEDs
