Drive orientation
HP LTO Ultrium drives will operate in 0°, –90° and +90° orientations when viewed from the front
panel. In addition, in the 0° axis, the drive will operate with +20°nose-up tilt.
NOTE:SAS drives should be powered from the normal rear panel connector, not through the
power part of the SAS connector.
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.

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 server enclosures and in
external desktop enclosures to verify EMC performance against the regulatory standards in force at
the time of introduction.
Products will comply with new regulatory standrads by or before the date of withdrawal of the
superseded standards, during their prodution life.

LTO-Cartridge Memory (EEPROM)
LTO Cartridge Memory (LTO-CM) is EEPROM 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.
•Power to the transponder is coupled through the interface.
•The range depends on implementation (maximum 10 to 20 mm). The best error rate
performance occurs at short distances.
Media24
HP restricted
Page 25
•The memory can be read from below (by a drive) or the front (in libraries).
•8192 bytes
•Organized as 255 x 32 byte blocks
•>500K write cycles, 20 year data retention life
•Write/read size is word-wide (2 bytes) or block-wide (32 bytes)
Further information
•For suggestions of how to make use of cartridge memory in libraries, see “LTO Cartridge
Memory (LTO-CM)” in Chapter 5, “Supporting LTO Ultrium Features” in Software Integration,
Volume 2 of the HP LTO Ultrium Technical Manual.
HP LTO Ultrium 4 drives are specified to interchange data cartridges with other tape drives that
comply to the LTO U-28, U-316 and U-416 specification documents:
•Cartridges are read on a drive in good operating condition, and have been written on a
logo-certified drive in good condition.
•Environmental conditions (including DC voltage supplies) are within the specified limits.
Future compatibility
In future, HP LTO 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 LTO Ultrium drives will always maintain write and read compatibility with other manufacturers’
LTO Ultrium drives and tapes that meet the LTO Ultrium format specification.
Streaming native data rate range (3:1)40–120 MB/s (LTO 4)
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:
The drive will match the throughput of any host up to the maximum native transfer rate multiplied by
the current compression ratio. There is no performance penalty for hosts that are slower than the
maximum. This capability is accomplished with a 128 MB buffer and the Adaptive Tape Speed
(ATS) algorithm.
27–80 MB/s (LTO 3)
13.7–35.6 MB/s (LTO 2)
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.

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 LTO Ultrium drives) 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
