5.2.2 Performance highlights
In general terms, Half-High drives are designed for small to medium workload requirements whereas Full-High drives are designed for medium to large workloads. Although the data rates between Half-High and Full-High are the same at 160 MBps, Full-High drives have significantly better times for rewind/locate operations and file access than that of the Half-High equivalent. Full-High drives also provide three times the load/unload life. Therefore, if you run applications that are highly dependent on tape processing speed, take advantage of the significant performance improvements that are provided by this tape drive. Table 5-1 shows the performance characteristics of the TS2360 tape drive.

By using the built-in data compression capability of the tape drive, greater data rates than the native data transfer rate can be achieved.
|
Important: Although the TS2360 tape drive provides the capability for excellent tape performance, other components of the system might limit the actual performance that is achieved. Also, although the compression technology that is used in the tape drive can typically double the amount of data that can be stored on the media, the actual degree of compression that is achieved is highly sensitive to the characteristics of the data that is being compressed.
|
5.3 Media
To ensure that the IBM Ultrium tape drive conforms to the IBM specifications for reliability, only IBM LTO Ultrium tape cartridges should be used. Other LTO-certified data cartridges can be used, but they might not meet the standards of reliability that are established by IBM.
5.3.1 Data cartridges
The TS2360 tape drive uses the Ultrium 6 Data Cartridge. It has a native capacity of 2.5 TB, and compressed capacity of 6.25 TB with a 2.5:1 compression ratio. It uses a linear, serpentine recording format. The TS2360 tape drive reads and writes data on 2176 tracks, 16 tracks at a time.
The outside of the Ultrium 6 cartridges is black; WORM cartridges are black and silvery gray. The cartridge has a nominal life of 20,000 load and unload cycles.
In Table 5-2, the compatibility of the Ultrium Data Cartridges and tape drives are shown. Ultrium 1, Ultrium 2, and Ultrium 3 Data Cartridges are not supported when Ultrium 6 tape drives are used.

5.3.2 Write Once Read Many cartridges
Certain records retention and data security applications require a Write Once Read Many (WORM) method for storing data on tape. To meet this data storage requirement, a WORM feature is available on IBM LTO Ultrium generation 3, 4, 5, and 6 drives. You can enable the WORM feature by upgrading to WORM-capable drive firmware and by using a special WORM tape cartridge.
A specially formatted WORM tape cartridge is required because standard Read/Write media are incompatible with the WORM feature. Each WORM cartridge has a unique, worldwide cartridge identifier (WWCID), which comprises the unique CM chip serial number and the unique tape media serial number.
For more information about WORM media, see “WORM tape format” on page 47.
5.3.3 Cleaning cartridges
A specially labeled IBM LTO Ultrium Cleaning Cartridge cleans the drive. One cleaning cartridge is included in the shipping package of the TS2360 tape drive.
|
Important: The drive automatically ejects an expired cleaning cartridge.
|
For more information about the cleaning cartridge, see “Specifications for cleaning cartridges” on page 55.
5.3.4 Cartridge memory (LTO-CM)
All generations of the IBM LTO Ultrium Data Cartridges include a Linear Tape-Open Cartridge Memory (LTO-CM) chip, which is a passive contact-less silicon storage device that is physically a part of the cartridge. It is designed to hold information about specific cartridge, the media in the tape drive and the data on the media.
The LTO-CM enhances the efficiency of the cartridge and aids in determining the reliability of the cartridge by storing data about its age, how many times it was loaded, and how many errors it accumulated. Whenever a tape cartridge is unloaded, the tape drive writes any pertinent information to the cartridge memory. A cleaning cartridge's LTO-CM chip tracks the number of times that the cartridge is used to prevent it being used more than 50 times. The storage capacity of the Ultrium 6 Tape Cartridge Memory Chip is 16320 bytes. Communication between the TS2360 tape drive and the LTO-CM is via a low-level radio frequency field transmitted by the drive to the cartridge.
5.4 Encryption
The IBM Storage System TS2360 tape drive supports host Application Managed Encryption (AME), which uses T10 encryption protocols. Data encryption is supported with LTO Ultrium 4, Ultrium 5, and Ultrium 6 Data Cartridges only.
The encryption-enabled drive contains the necessary hardware and firmware to encrypt and decrypt host tape application data. The Encryption policy and encryption keys are provided by the host application, and there is no encryption setup required (or available) for this drive.
Encryption requires the latest tape device drivers that are available on the Fix Central download site, which is available at this website:
For more information about tape encryption, see IBM System Storage Open Systems Tape Encryption Solutions, SG24-7907.
5.5 Linear Tape File System
IBM Linear Tape File System (LTFS) is the first file system that works with the multiple partitioning that is available on LTO Ultrium 6 and LTO Ultrium 5 tape and brings a new level of use and portability to open systems tape storage. This storage software helps you reduce complexity in data management and access time through the enablement of a self-describing tape that includes a simple file index. It helps to decrease tape, file management, and archive costs while improving response time for new business needs.
LTFS allows files and directories to be shown on desktop and the directory listing and you can drag-and-drop files to and from tape. LTFS also supports data exchange and has a simple one-time installation.
The IBM LTFS SDE software is included with each TS2360 and uses LTO 6 tape partitioning. It enables a self-describing tape file format and delivers an easy tape storage and distribution solution without the use of more database applications. IBM Linear Tape File System is the perfect solution for those in the Media and Entertainment industry and other fields that need massive data storage on tape for long retention periods, such as banking, scientific research, and government sectors. For more information and list of supported operating systems, see this website:
For more information about LTFS-SDE, see Linear Tape File System: Installation and Configuration, SG24-8090.
