Available models include: T10000 A, B, C
The T10000 uses partial response, maximum likelihood (PRML)
complemented by dual magneto-resistive (MR) head technologies that
provide
32
channels that write data to the tape and read it back.
This dual-head technology:
The new tape cartridge for this drive uses a single-reel hub design—the
supply reel is inside the cartridge and the take-up reel is inside the tape drive.
The interface connections to the T10000 are strictly fiber-optic—either Fibre
Channel or FICON (
future offering
)—to support the high rate of data transfers.
The T10000 supports a variety of operating system platforms:
Available models include LTO2, LTO3, LTO4, and LTO5.
Hewlett-Packard LTO tape drives are a small, modular,
capacity-centric
drive.
These drives conform to the LTO open standard where drive technology is based
on an open standard that provides media compatibility across all brands and
manufacturers of LTO Ultrium products.
LTO drives record data using write-equalized run length limited (RLL) code.
LTO2 uses an LZ1-based compression scheme while LTO3 uses PRML and a
derivative of the Advanced Lossless Data Compression (ALDC-2) technique.
Data is written in a linear format with a serpentine pattern—the tape reverses
direction after each set of tracks is written to the end of tape (EOT).
The tape cartridge for LTO Ultrium drives is a single-reel hub design—the supply
reel is inside the cartridge and the take-up reel is inside the tape drive.
The drives require different media and must be labeled as such:
Note:
HP drives support the LTO standard for backward compatibility, which is
to write back one generation and read back two generations.
The target customers for HP LTO drives are mid-range tape automation
environments with Windows NT/2000, Netware, Linux, and UNIX (HP-UX).
