3 Electr ical requirements

PSU requirements

Internal and rack-mounted drives

The drives are specified to operate at 5V±5% and 12V±10%. Any PSU used to power the drive mu st be capable of providing 5V nominal (w hen the drive pulls 5A on the 5V rail) and 12V nominal (when the drive pulls 2A on the 12V rail). HP recommends a 10% buffer when selecting a power supply source capable of delivering the amperage and power required.

LTO-Cartridge Memory (EEPR OM)

LTO Cartridge Memory (LTO-CM) is EEPROM memory that is embedded in every LTO Ultrium tape cartridge. It is non-volatile and is contactless in that it is read by RF coupling rather than electrical contact.

Interface specification

• Contactless, passive RF interface using a proximity inductive coupling with a range in the

order of millimeters.

• P ower to the transponder is coupled thr o ugh the interface.

• The range depends on implementation (10 to 20 mm is the maximum). The best error rate

performance will occur at short distances.

• The memory can be read from below (by a drive) or from the front (in libraries).

• 32 kilobits (4 kilobytes)

• Organized as 12 8 x 32 byte block s

• >500K write cycles, 20 year data retention life

• Write size is word wide (2 bytes) or block wide (32 bytes)

• The transfer- rate performance of the cartridge memory is as follows:

• Reads:

• Writes:

•

32 byte read: ~ 5.8 ms 32 byte write: ~ 15.8 m s

2 byte: ~20 Kb/s 32 byte: ~70 Kb/s 4 KB: ~0.5s

2 byte: ~1.4 Kb/s 32 byte: ~18.5 Kb/s 4 KB: ~1.8s

Further information

• For general information about LTO-CM, see “LTO Cartridge Memory” in Chapter 5,

“Cartridges” in Background to Ultrium Drives, Volume 6 of the Ultrium Technical Manual.

• For suggestions of how to make use of cartridge memory in libraries, see “LTO Cartridge

Memory (L TO-CM)” in Chapter 5, “Supporting Ultrium Feature s” in Soft ware Integration, Volume 2 of the Ultrium Technical Manual.

Compatibility

HP Gen 3 Ultrium drives are specified to interchange data cartridges with other tape drives that comply to the LTO U-18, U-28, and U-316 specification documents:

Capacity (2:1 compression) Format Write Read

800 GB WORM Ultrium-3 Yes Yes 800 GB (680m) Ultrium-3 Yes Yes 400 GB (580m) Ultrium- 2 Yes Yes 200 GB (580m) Ultrium-1 No Yes 100 GB (290m) Ultrium-1 No Yes

This specif i cation is only applicable when:

• Cartridges carry the Ultrium logo.

• Cartridges are not damaged or faulty.

• Cartridges are read on a drive in good operating condition, and have been written on a

logo-certified drive that is in good condition.

• The environmental conditions (including DC voltage supplies) ar e w ithin the s pec if i ed limits .

NOTE: HP Gen 3 Ultrium drives do not support 10 GB and 30 GB cartridges. HP

recommends the use of the logically for test purposes.

Future compatibility

In future, HP Ultrium dri ves will always be capable of r eading and writing tapes from the curre nt generatio n and one generation bef ore , and reading tapes fr om two gener ations befo re. HP Ultrium drives will always maintain write and read compatibility with other manufacturers’ Ultrium drives and tapes that meet the LTO Ultrium format specification.

Compressed (2:1): 160 MB/s 160 MB/s

Burst transfer rate Ultra3 SCSI wide: 320 MB/s

6.6–20 MB/s (U1)

The bandwidth of the data compression engine determines the drive’s streaming capabilities based on the compressio n ratio of the data it is handling as follows:

Compression Engine Bandwidth: 120 MB/s Maximum Streaming Compression Ratio: 3:1

The drive will match the throughput of any host up to the maximum native transfer rate multiplied by the cur ren t compr ession r atio . Ther e w ill not be an y performance penalty fo r hosts that are slower than the maximum. This capability is accomplished with a 64 MB buffer and the Adaptive Tape Speed (ATS) algorithm.

Speeds

Data compression

The compression engine uses an enhanced algorithm based on ALDC where data expansion due to redundant data is minimized to <5%. This is achieved by having two compression schemes (normal and pass-through) with the ability to switch dynamically between them.

It is possible to force the drive to use Scheme 2 (pass-through mode) of the LTO-DC algorithm using the Data Compression mode page or the SDCA parameter in the Sequential Access Mode Page.

Maximum tape speed 7.00 m/s Tape read/write speed 5.32 m/s (Ultrium-3), 5.50 m/s (Ultrium-1/2) Tape rewind speed 7.00 m/s

The following table shows approximate backup times for the available tape cartridges:

Cartridge Time

Load/unload times

The load and unload times are as follows:

SCSI FC

Typical load time to BOT, ready to read or write <19s* <19s* Unload time, excluding rewind <19s <19s Automation eject (tape unthreaded) <1s <1s

* The unload time for WORM cartridges is greater, typically 22s

11 Automation Control Interface

Specification

Physical interface

• RS-422, Drive Sense, Library Sense, Reset and Attention signals

• A default of 9600 baud at power-on, after a tape drive reset and after an ACI reset. After

that, the library can configure the tape drive to use other baud rates (19200, 38400, 57600 and 115200 baud for HP Ultrium dri ves) using the Set Baud Rate command.

• 1 start bit, 8 data bits, 2 stop bits, no parity

Protocol

• Binary data packets, including checksum, packet length, status, sequence number,

• XON/XOFF flow control

• Positive or negative acknowledgement of transmission

• Constant polling not necessary— the drive returns status upon completion of each

command
