1.1 LTO overview

The Linear Tape-Open (LTO) program is a joint initiative of Hewlett-Packard, IBM, and Seagate Technology. In 1997, the three companies set out to enable the development of best-of-breed tape storage products by consolidating state-of-the-art technologies from numerous sources. The three companies also took steps to protect client investment by providing a four-generation road map and establishing an infrastructure to enable compatibility between competitive products.

The LTO technology objective was to establish new open-format specifications for high capacity, high performance tape storage products for use in the midrange and network server computing environments, and to enable superior tape product options.

LTO program cooperation goes beyond the initial three companies. LTO format specifications have been made available to all who want to participate through standard licensing

provisions. LTO program technology has already attracted a number of other industry leaders, so that LTO-specified products (tape drives and tape storage cartridges) will reach the market from multiple manufacturers, not just the Technology Provider Companies. This is critical to meeting an open market objective, and is accomplished through open licensing of the technology.

Cooperation is also evident in the LTO program requirement that all products produced by licensees be technically certified annually. The primary objective of this certification is to help determine whether LTO format cartridges will be exchangeable across drives produced by different Ultrium manufacturers. In other words, LTO compliant media from any vendor can be read and written in LTO compliant drives from any vendor.

All three consortium members (IBM, HP, and Seagate) are now shipping LTO Ultrium products, and numerous other licensees are shipping hardware and media.

Open Systems, SG24-5946.

The LTO Ultrium road map (Figure 1-1 on page 5) shows the evolution of LTO technology. At the time of writing, IBM Ultrium generation 2 and 3 products are offered; however, there are many existing installations of now-withdrawn Ultrium 1 products, so we also include them for your reference. The information in the road map is given as an indication of future

developments by the three consortium members, and is subject to change.

WORM tape format

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.

(38)

Figure 1-6 IBM TotalStorage 3581 Tape Autoloader

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).

(39)

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

Remote Management Unit

Available as an optional feature, a

Remote Management Unit

(RMU) provides an Ethernet port, so that the library can be configured as a TCP/IP device in the network. Library status can be sent to the network as Simple Network Management Protocol (SNMP) traps. The IBM Ultrium Tape Library Specialist enables network access (via Web browser) to the library for more detailed status and for updating the firmware of the library. All library Operator panel functions can be accessed using the IBM Ultrium Tape Library Specialist.

Figure 1-7 shows the IBM 3581 2U.

Figure 1-7 IBM TotalStorage 3581 2U Tape Autoloader

1.1.5 IBM TotalStorage 3582 Tape Library

The IBM TotalStorage 3582 Tape Library (abbreviated to IBM 3582) is an entry-level tape library that can accommodate one or two Ultrium 2 or Ultrium 3 drives. Designed for tape automation, the IBM 3582 attaches to a variety of server and operating system platforms (See 1.2.1, “Hardware server platforms” on page 28).

The IBM 3582 has one model, the 3582-L28. The IBM 3582 uses the IBM Ultrium 2 and Ultrium 3 tape drives for fast data transfer and reliability in automated library service. The Ultrium 2 cartridge has a native capacity of 200 GB. The Ultrium 3 cartridge has a native capacity of 400 GB.

Each aspect of the library subsystem has been designed for repeated, reliable unattended tape handling. The tape handling mechanism is designed to reliably move cartridges to IBM

(40)

Ultrium Tape Drives within the library. The IBM Ultrium tape cartridges have been refined using the many years of IBM tape experience to provide a tape cartridge that provides fast data transfer, but stands up to the rigors of automated handling.

The IBM 3582 is designed for easy expansion. It has a one-cartridge Import/Export station and 22 data cartridge slots. With Ultrium 2 drives and media, the IBM 3582 provides a media capacity of up to 4.8 TB (9.6 TB with 2:1 compression) and a sustained data rate of up to 35 MB per second (uncompressed). With Ultrium 3 drives and media, the IBM 3582 provides a media capacity of up to 9.6 TB (19.2 TB with 2:1 compression) and a sustained data rate of up to 80 MB per second (uncompressed).

The IBM 3582 comes standard with multi-path architecture, which allows the sharing of the library robotics. This allows the IBM 3582 to be partitioned into one to two logical libraries, providing each library with its own control path, drives, and storage slots. The Import/Export station (slot) is shared among each logical library on a first come, first served basis. The cartridges under library control are not shared among the logical libraries. This feature will enable up to two heterogeneous applications to manage a single physical library.

The tape library Import/Export (I/O) station allows cartridges to be inserted and removed without disrupting library operation. The are two I/O station options:

A single import/export slot option to load or remove single tapes Two 7-slot magazines to perform bulk load and unloads

A Bar Code Reader is standard for reading data cartridge labels, although the library can function with unlabeled cartridges.

The IBM 3582 with Ultrium 2 and Ultrium 3 drives supports SCSI HVD, SCSI LVD and native Fibre Channel connected Ultrium 2 or Ultrium 3 drives. The direct attached SCSI drives may be any mixture of SCSI LVD, SCSI HVD, or Fibre Channel up to a total of two drives.

Control path failover

For enhanced availability you can use control path failover. This optional feature provides automatic control path failover to a preconfigured redundant control path in the event of a loss of a host adapter or control path drive, without aborting the current job in progress. Support is provided under AIX, Linux, HP-UX, Windows, and Solaris™ for both SCSI and Fibre Channel attachments when the IBM tape device drive is used.

Data path failover and load balancing

Data path failover and load balancing exclusively support native Fibre Channel Ultrium 2 and Ultrium 3 Tape Drives in a IBM 3582 library using the IBM tape device driver for AIX, Linux, and Solaris. Note: Load balancing is not supported on Solaris.

Data path failover

provides a failover mechanism in the IBM device driver, which enables you to configure multiple

redundant paths in a SAN environment. In the event of a path or component failure, the failover mechanism is designed to automatically provide error recovery to retry the current operation using an alternate, preconfigured path without aborting the current job in progress. This allows you flexibility in SAN configuration, availability, and management.

When accessing a tape drive device that has been configured with alternate pathing across multiple host ports, the IBM device driver automatically selects a path through the host bus adapter (HBA) that has the fewest open tape devices, and assigns that path to the

application. This autonomic self-optimizing capability is called

load balancing

. The dynamic load balancing support is designed to optimize resources for devices that have physical connections to multiple HBAs in the same machine. The device driver is designed to dynamically track the usage on each HBA as applications open and close devices, and balance the number of applications using each HBA in the machine. This may help optimize

HBA resources and improve overall performance. Further, data path failover provides autonomic self-healing capabilities similar to control path failover, with transparent failover to an alternate data path in the event of a failure in the primary host-side path.

Data path failover and load balancing for Ultrium 3 Tape drives in all supported operating environments require an optional feature 1681 and the control path failover feature code 1680. Data path failover and load balancing for Ultrium 2 Tape drives in an AIX environment require the control path failover feature 1680 but do not require an optional feature; in non-AIX environments, the control path failover feature 1680 and an RPQ are required.

Remote Management Unit

Available as an optional feature, a Remote Management Unit (RMU) provides an Ethernet port, so that the library can be configured as a TCP/IP device in the network. Library status can be sent to the network as Simple Network Management Protocol (SNMP) traps. The IBM Ultrium Tape Library Specialist enables network access (via Web browser) to the library for more detailed status and control. All library Operator panel functions can be accessed using the IBM Ultrium Tape Library Specialist.
