Configurators can help you define your product to your unique requirements. They generate all the information you need to enter in the ordering system.

The IBM System Storage TS2240 Tape Drive is an external stand-alone or rack-mountable shelf unit and contains a Linear Tape-Open (LTO) Ultrium 4 Half-High Tape Drive designed for the heavy demands of backup tape storage. It is supported for serial-attached SCSI (SAS) attachment to selected IBM System x products and non-IBM servers that support those interface specifications. The TS2240 Tape Drive Model incorporates fourth-generation IBM LTO Ultrium technology. It offers the following significant improvements over the Ultrium 3 Tape Drive:

Increased performance - Maximum tape drive throughput data rate performance is up to 120 MB/sec native data transfer rate. Data tracks are written 16 at a time.
Note: Although the TS2240 Tape Drive provides the capability for excellent tape performance, other components of the system may limit the actual performance achieved. Also, although the compression technology used in the tape drive can typically double the amount of data that can be stored on the media, the actual degree of compression achieved is highly sensitive to the characteristics of the data being compressed.

Larger capacity - The tape cartridge capacity, doubled over the Ultrium 3 Data Cartridge, up to 800 GB native physical capacity (1,600 GB with 2:1 compression), with the use of the IBM LTO Ultrium 800 GB Data Cartridge. This is achieved by increasing the linear density, the number of tape tracks, and the media length. The tape itself is an advanced metal particle tape developed to help provide durability and capacity.

Ultrium 3 cartridge compatibility - The Ultrium 4 Half-High Tape Drive can read and write on Ultrium 4 and 3 cartridges, and can read LTO Ultrium 2 Data Cartridges.
SAS attachment - The TS2240 Tape Drive comes with a 3 Gbps single port SAS attachment, for connection to a wide spectrum of open system servers. The new model will attach to selected System x and PC servers that support Microsoft Windows and Linux systems.

Encryption supported on Ultrium 4 Half-High SAS tape drives - The IBM System Storage TS2240 LTO Ultrium 4 Half-High SAS Tape Drive will support Application Managed Encryption of data on the base drive with Ultrium 4 media meeting LTO consortium specifications.

WORM media support - The IBM 3589 Ultrium 4 800 GB WORM Tape Cartridges are designed for applications such as archiving and data retention as well as those applications requiring an audit trail. These cartridges work with the IBM LTO Ultrium 4 Tape Drive to help prevent the alteration or deletion of user data. IBM Ultrium 800 GB WORM Tape Cartridges can be ordered as unique 3589 models with the following features:

Pre-labeling, with the ability to specify a starting volume serial number and color coding

Packaging in individual jewel cases or in bulk

Cartridge memory, built into every cartridge, which helps to enhance functionality and media reliability by storing access history and media performance information, for use by the tape drive every time the cartridge is accessed

Half-inch particle tape with a 800 GB WORM native capacity in a single cartridge

Larger internal data buffer - There is a 256 MB internal data buffer in the Ultrium 4 Tape Drive as compared to a 128 MB internal data buffer in the Ultrium 3 Tape Drive.

Proven IBM LTO Ultrium features of the IBM LTO Ultrium 4 Half-High Tape Drive include:

Servo and track layout technology - There are 896 data tracks in Ultrium 4 versus 704 data tracks in Ultrium 3. The high-bandwidth servo system features a low-mass servo to help more effectively track servo bands and improve data throughput with damaged media in less-than-optimal shock and vibe environments.

Surface Control Guiding Mechanism - IBM's patented Surface Control Guiding Mechanism, used in the IBM TS2240 Tape Drive, is designed to guide the tape along the tape path. This method uses the surface of the tape, rather than the edges, to control tape motion. This helps reduce tape damage (especially to the edges of the tape) and tape debris, which comes from the damaged edges and can accumulate in the head area.

Magneto resistive (MR) head design - Use of flat lap head technology in MR heads for Ultrium 4 helps minimize contact, debris accumulation, and wear on the tape as it moves over the read/write heads.

Digital speed matching - The Ultrium 4 Half-High Tape Drive is designed to perform dynamic speed matching (at one of seven speeds, 31 to 120 MB/sec) to adjust the drive's native data rate as closely as possible to the net host data rate (after data compressibility has been factored out). This helps reduce the number of backhitch repositions and improve throughput performance. Speed matching on the Ultrium 4 Half-High model ranges from 31 to 120 MB/sec versus 30 to 80 MB/sec on the Ultrium 3 Half-High model.

Power management - Ultrium 4 Tape Drive power management function is designed to control the drive electronics to be either completely turned off or stay in a low-power mode when the circuit functions are not needed for drive operation.

Separate writing of multiple filemarks - Separate writing of multiple filemarks is designed to evoke any write command of two or more filemarks to cause a separate data set to be written containing all filemarks after the first. It helps improve performance if a subsequent append overwrites somewhere after the first filemark. This change helps prevent having to rewrite data sets containing customer data and the first filemark if such an append occurs.

LTO Data Compression (LTO-DC) - Ultrium 4 uses LTO-DC, which is an implementation of a Lempel-Ziv class 1 (LZ-1) data compression algorithm. LTO-DC is an extension of Adaptive Lossless Data Compression (ALDC) and an improvement over previous IBM lossless compression algorithms. IBM's patented "Scheme-Swapping" compression is designed to look ahead at incoming data and determine the most efficient storage method (either ALDC or pass-thru mode) to help provide optimal data compression and increased data throughput.

LTO Cartridge Memory (LTO-CM) - Contained within the LTO Ultrium data cartridge is the LTO-CM, which is a passive, contactless silicon storage device that is physically a part of the cartridge. The LTO-CM is used to hold information about that specific cartridge, the media in the cartridge, and the data on the media. The storage capacity of the LTO-CM is 8 KB. Communication between the drive and the LTO-CM is via a low-level RF field transmitted by the drive to the cartridge.

Ultrium 800 GB Data Cartridge:

The tape cartridge physical capacity of the IBM Ultrium 800 GB Data Cartridge has doubled over the IBM Ultrium 400 GB Data Cartridge to up to 800 GB native physical capacity (1,600 GB with 2:1 compression). IBM LTO Ultrium 4 Tape Drives can read and write Ultrium 3 data cartridges, and read only Ultrium 2 data cartridges. LTO Ultrium 800 GB data cartridges can be ordered using machine type 3589, LTO Ultrium tape cartridges or part number 95P4278 at the time of purchase.

These cartridges have been designed to provide several enhancements over previous tape technologies. They are designed to work with tape drives that have increased tape speeds and high-density data recording. The case is specially designed for use in automated libraries, and is designed for repeated, unattended handling. The tape itself is an advanced metal particle tape developed for durability and capacity.

The TS2240 Tape Drive provides an excellent migration path from digital linear tape (DLT or SDLT), 1/4-inch, 4mm, or 8mm Tape Drives. It can be a cost effective solution for backup, save-and-restore, and archiving functions as the entry point for the family of IBM Ultrium tape products.
