Drive orientation
An HP Ultrium drive will operate in the 0°, –90° and +90° when viewed from the front panel.
In addition, in the 0° axis, the drive will operate with +20°nose-up tilt.

Physical specification
3 Electrical 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 must be capable of providing 5V nominal (when 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.

4 Electromagnetic compatibility
NOTE: The EMC performance of internal storage products depends on the characteristics of
the system in which the product is installed. HP has tested products installed in network storage
system enclosures and in external desktop enclosures to verify EMC performance against the
regulatory standards in force at the time of introduction.

LTO-Cartridge Memory (EEPROM)
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.
21
Interface specification
•
Contactless, passive RF interface using a proximity inductive coupling with a range in the
order of millimeters.
•
•
Power to the transponder is coupled through 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 128 x 32 byte blocks
>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:
2 byte: ~20 Kb/ s
32 byte: ~70 Kb/ s
32 byte: ~18.5 Kb/ s
4 KB: ~0.5s
4 KB: ~1.8s
2 byte: ~1.4 Kb/ s
32 byte read: ~ 5.8 ms
32 byte write: ~ 15.8 ms

Memory (LTO-CM)” in Chapter 5, “Supporting Ultrium Features” in Software Integration,

This specification 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) are within the specified limits.
NOTE: HP Gen 3 Ultrium drives do not support 10 GB and 30 GB cartridges. HP
recommends the use of the SET CAPACITY SCSI command to shorten standard cartridges
logically for test purposes.
Future compatibility
In future, HP Ultrium drives will always be capable of reading and writing tapes from the
current generation and one generation before, and reading tapes from two generations before.
HP Ultrium drives will always maintain write and read compatibility with other manufacturers’
Ultrium drives and tapes that meet the LTO Ultrium format specification.

The bandwidth of the data compression engine determines the drive’s streaming capabilities
based on the compression ratio of the data it is handling as follows:
Compression Engine Bandwidth:
120 MB/ s
3:1
Maximum Streaming Compression Ratio:
The drive will match the throughput of any host up to the maximum native transfer rate
multiplied by the current compression ratio. There will not be any performance penalty for hosts
that are slower than the maximum. This capability is accomplished with a 64 MB buffer and
the Adaptive Tape Speed (ATS) algorithm.
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.
