Which backward compatibility is supported from lto3 to lto 1




















For third-party backup software support, you should go to the software vendor's website or use the Quantum compatibility guide that is available at www. These versions of Windows have native support for Travan Current members of the DDS family include the following:.

External USB 2. Both are available in internal and external form factors. Hewlett-Packard also produces USB 2. Some DDS-4 drives are also read compatible with DDS-2 media, which means they can be used in place of older drives for retrieving existing backups. It's important to check media compatibility with the drive manufacturer for details. The entire surface of the tape is used to store data, enabling more data to be placed in a given length of tape than with the linear recording techniques that the QIC and Travan family of drives use.

LVD is recommended for best performance. A sapphire media-cleaning blade that removes debris from the tape before it contaminates the drive. These improvements enable DAT 72 drives to run 10 times longer in dusty conditions than similar drives that don't have these features. Hewlett-Packard's DAT 72 drives include self-cleaning features and One Button Disaster Recovery, an easy-to-use disaster-recovery feature designed to restore a system to its most recent backed-up condition with the press of a button.

This feature is supported on several Hewlett-Packard ProLiant servers. Current drive manufacturers recommend of course! Consequently, installation and configuration of these drives is much more complex than with a Travan drive. Before installing any drive, you need to install the software drivers provided with the drive.

If additional software is needed, you should download it from the support page for the drive. You can download drivers for Windows, Linux, and other operating systems; TapeRX diagnostics; and firmware updates. To download these files, you select the drive type from the Quantum Software and Documentation Downloads page, at www.

Jumpers for enabling or disabling parity and termination power are usually located next to the SCSI device ID jumpers. DIP switches for advanced settings, such as data compression, operating system compatibility, SCSI Wide or Narrow, and others, are located at the bottom of the drive.

A small window shows the current device ID. You press buttons above and below the window to select a different device ID. DIP switches for advanced settings, such as data compression, operating system compatibility, SCSI Wide or Narrow, and others, are located at the bottom of the drive under a small access panel. Seagate was the original manufacturer of most of these drives, before it spun off its tape drive division as Certance. Quantum then purchased Certance in However, depending on the server operating system you use, you might need to adjust the position of DIP switches 5 through 8 and The default ON setting shown in Figure 9.

Quantum internal drives fit into half-height 5. If the CD contains drivers for your operating system, you should install the appropriate drivers. If a driver for your operating system is not supplied with the drive, you can download updates from the Hewlett-Packard website.

To determine software compatibility with a particular Hewlett-Packard tape backup drive, you can go to www. Next, you click the entry for each combination of drive and operating system for compatibility details and links to driver updates. Other jumpers should not be moved from their default locations.

Hewlett-Packard internal drives fit into half-height 5. For best performance, you should not connect the drive to a USB 2. This is in dramatic contrast to traditional helical-scan technology used by DDS and DAT 72 drives, in which the data is recorded in diagonal stripes, with a rotating drumhead, while a much slower tape motor draws the media past the recording head.

The result is a very durable drive and a robust medium. DLT drive heads have a minimum life expectancy of 15, hours under worst-case temperature and humidity conditions. SDLT uses several technologies to increase capacity and reliability over those of the already-impressive DLT standards. These include laser-guided magnetic recording LGMR , a pivoting optical servo on the backside of the media, thin-film magneto-resistive cluster heads for tape reading and writing, high-efficiency PRML channels for greater recording density, improved media coating, and a positive engagement tape-leading buckling mechanism.

This enables you to replace older, smaller drives with newer, larger drives without losing access to older backups. This media can also be read by SDLT drives. For external drives, you use push buttons to set the device ID. For other drives, see the documentation. As with any SCSI drive, if a tape drive is the last drive in the daisy-chain, it must be terminated. With external drives, you connect an external terminator to the second connector on the drive refer to Figure 9.

LTO Ultrium is the highest-performing and highest-capacity open standard tape backup system currently available for servers. Originally, LTO developed two standards: Ultrium optimized for high capacity and Accelis optimized for high speed.

Accelis was never adopted, in large measure because Ultrium provided comparable speeds at higher capacities. Thus, Ultrium and LTO are sometimes used interchangeably. The first Ultrium drives LTO-1 were released in LTO Ultrium technology divides a track half-inch tape into four data bands, separated by servo bands.

Two servo bands are used simultaneously to provide accurate head positioning and to overcome any flaws in the media. Tape is written bidirectionally at very high speeds. Each data band is written in the opposite direction from the previous band to help avoid cross-talk between data bands. The drive reads this information and uses it to help operate the cartridge in an optimal manner.

This information can also be read by an RF receiver before the cartridge is inserted into a tape drive. WIth lto 3 we could still write to our lto 2 tapes but with lto 4 we were stuck with only reading our lto 4 tapes.

In the end we determined that our lto 2 tapes were aging many were 3 years old and that it was probably time to move on so we went with LTO 4 and bought new tapes. To continue this discussion, please ask a new question.
