Beginning with LTO Ultrium 3, Write Once Read Many (WORM) functionality provides for non-erasable, non-rewritable operation with tape media and is designed for long term tamper resistant record retention
The LTO Ultrium 3 specification for WORM includes the use of low level encoding in the Cartridge Memory (CM), which is also mastered into the servo pattern as part of the manufacturing process. This encoding is designed to prevent tampering.
Data can be appended at the end of a WORM cartridge to which data was previously written, allowing the full use of the high capacity tape media.
LTO Ultrium 3 WORM cartridges can be used with any LTO Ultrium 3 tape drive with the appropriate microcode and firmware.
LTO Ultrium 3 non-WORM enabled and WORM enabled drives can coexist in the same library.

1.1.2 IBM TotalStorage 3580 Tape Drive
The IBM TotalStorage 3580 Tape Drive (abbreviated to IBM 3580) is an external, stand-alone, SCSI-attached tape drive that attaches to a variety of server and operating system platforms (see 1.2.1, “Hardware server platforms” on page 28).
The IBM 3580 can also connect to Fibre Channel server Host Bus Adapters through the IBM SAN Data Gateway Routers models 2108-R03 or 2108-G07.
The IBM 3580 is available as four separate model types, depending on the Ultrium format and SCSI interface.
IBM 3580-L23 has an Ultrium 2 drive and a Low-Voltage Differential (LVD) Ultra2 SCSI attachment that connects to LVD fast/wide adapters.
IBM 3580-H23 has an Ultrium 2 drive and a High-Voltage Differential (HVD) Ultra™ SCSI attachment that connects to HVD fast/wide adapters.
IBM 3580-L33 and IBM 3580-L3H have an Ultrium 3 drive and a Low-Voltage Differential (LVD) Ultra SCSI attachment that connects to LVD fast/wide adapters.
The IBM 3580-L33 and IBM 3580-L3H are functionally identical; the only difference is the IBM 3580-L3H is an Express Model, which is part of the On-Demand Express Portfolio.
The four previously available model types are:
IBM 3580-L11 and IBM 3580-L13 have an Ultrium 1 drive and a Low-Voltage Differential (LVD) Ultra2 SCSI attachment that connects to LVD fast/wide adapters.
IBM 3580-H11 and IBM 3580-H13 have an Ultrium 1 drive and a High-Voltage Differential (HVD) Ultra SCSI attachment that connects to HVD fast/wide adapters.
The IBM 3580-L11 and IBM 3580-L13 are functionally identical; the only difference is that the IBM 3580-L13 has a three-year Customer Element Exchange warranty. The IBM 3580-H11 and IBM 3580-H13 are functionally identical; the only difference is that the IBM 3580-H13 has a three year Customer Element Exchange warranty.

1.1.3 IBM TotalStorage 3581 Tape Autoloader
The IBM TotalStorage 3581 Tape Autoloader (abbreviated to IBM 3581) is an external, stand-alone or rack-mounted autoloader that can incorporate an IBM Ultrium 1 or Ultrium 2 tape drive. It attaches to a variety of server and operating system platforms (See 1.2.1,
“Hardware server platforms” on page 28).
The IBM 3581 capacity with Ultrium 1 drives is seven tape cartridges, providing a media capacity of up to 700 GB (1.4 TB with 2:1 compression) data storage per library, and a sustained data rate of up to 15 MB per second (uncompressed).
The IBM 3581 capacity with Ultrium 2 drives is seven tape cartridges, providing a media capacity of up to 1.4 TB (2.8 TB with 2:1 compression) data storage per library, and a sustained data rate of up to 35 MB per second (uncompressed).
The six model types are:
IBM 3581-L17 has an Ultrium 1 drive and a LVD Ultra2 SCSI attachment.
IBM 3581-L13 has an Ultrium 1 drive and a LVD Ultra2 SCSI attachment and comes with a three-year Customer Element Warranty.
IBM 3581-L23 has an Ultrium 2 drive and LVD Ultra2 SCSI attachment and comes with a three-year Customer Element Warranty.
IBM 3581 H-17 has an Ultrium 1 drive and a HVD Ultra SCSI attachment.
IBM 3581 H-13 has an Ultrium 1 drive and a HVD Ultra SCSI attachment and comes with a three-year Customer Element Warranty.
IBM 3581 H-23 has an Ultrium 2 drive and a HVD Ultra SCSI attachment and comes with a three-year Customer Element Warranty.
Figure 1-6 on page 10 shows the IBM 3581.
Note: All models of the IBM TotalStorage 3581 Tape Autoloader (IBM 3581-L17/H17, IBM 3581-L13/H13, and IBM 3581-L23/H23) were withdrawn from marketing in October 2004.
The replacement is the IBM TotalStorage 3581 2U Tape Autoloader Model L28; see 1.1.4,
“IBM TotalStorage 3581 2U Tape Autoloader” on page 10.

1.1.4 IBM TotalStorage 3581 2U Tape Autoloader
The IBM TotalStorage 3581 2U Tape Autoloader (abbreviated to IBM 3581 2U) is a desktop or rack-mountable unit (requiring two rack units, thus “2U”) that operates in automatic,
sequential, or random mode and comes equipped with a robotic interface that moves tape cartridges to and from the drive and cartridge carousel. The IBM TotalStorage 3581 2U Tape Autoloader attaches to a variety of server and operating system platforms (See 1.2.1,
“Hardware server platforms” on page 28).
The IBM 3581 2U uses the IBM Ultrium 2 and Ultrium 3 drives for fast data transfer and reliability in automated library services. The Ultrium 2 cartridge has a native capacity of 200 GB. The Ultrium 3 cartridge has a native capacity of 400 GB.
The IBM 3581 2U has an eight-cartridge capacity. With an IBM Ultrium 2 drive, the native media capacity is 1.6 TB (3.2 TB with 2:1 compression) with a sustained data rate up to 35 MB/sec (uncompressed). With an IBM Ultrium 3 drive, the native media capacity is 3.2 TB (6.4 TB with 2:1 compression) with a sustained data rate up to 80 MB/sec (uncompressed) with Ultrium 3 media.
The IBM 3581 2U’s robotic system includes an I/O door, a cartridge carousel with eight cartridge slots, and a cartridge loader. The I/O door allows the importing or exporting of a single cartridge to or from the Autoloader. The cartridge carousel encircles the Ultrium 2 or 3 drive and positions the specified cartridge slot in front of the tape drive. A robotic cartridge loader moves the cartridges between the cartridge slots and the tape drive.
The four models of the IBM 3581 2U are:
The IBM TotalStorage 3581 2U Tape Autoloader Model L28
– The IBM 3581-L28 has an Ultrium 2 drive and a Low-Voltage Differential (LVD) Ultra 160 SCSI attachment that connects to LVD fast/wide adapters.
– Using the optional High-Voltage Differential (HVD) converter (feature #3104), a SCSI LVD to HVD converter/expander converts the Autoloader’s low voltage differential (LVD) to wide high voltage differential (HVD).
The IBM TotalStorage 3581 2U Tape Autoloader Model F28
– The IBM 3581-F28 has an Ultrium 2 drive and a 2 Gbps native switched fabric Fibre Channel attachment.
The IBM TotalStorage 3581 2U Tape Autoloader Model L38/L3H
– The IBM 3581-L38 has an Ultrium 3 drive and a Low-Voltage Differential (LVD) Ultra 160 SCSI attachment that connects to LVD fast/wide adapters.
The IBM TotalStorage 3581 2U Tape Autoloader Model F38/F3H
– The IBM 3581-F38 has an Ultrium 3 drive and a 2 Gbps Native Switched Fabric Fibre Channel attachment.
The IBM 3581-L38 and IBM 3581-L3H are functionally identical. The IBM 3581-F38 and IBM 3581-F3H are functionally identical.The only difference is the IBM 3580-L3H and IBM 3581-F3H are Express Models and are part of the On-Demand Express Portfolio.
