Introduction
Overview The Hewlett Packard (HP) LTO4 is the fourth-generation of Ultrium, Linear
Tape-Open tape drives. This generation offers more capacity and increased
performance than earlier versions of LTO tape drives.
Encryption
Capable
The Hewlett Packard LTO4 is the first, non-StorageTek T-Series tape drive to
support the Crypto Key Management System Version 2.0.
This encryption-capability requires a special, custom designed, Ethernet
card—called the Dione card—that enables the LTO4 drive to connect to and
interface with the Key Management System (KMS) network.
With this connection, the LTO4 is capable of communicating with the KMS
to transfer encryption keys over the secure network.
Note: The HP LTO4 can only use one encryption key at a time. During a read
operation, if another encryption key is found, the Dione card requests the
key directly from the KMS.
Media
(Native capacity)
The HP LTO4 drive with LTO4 media can store up to 800 GB of data.
This drive can also read and write on LTO3 media (400 GB), and provides
read-only capabilities with LTO2 media (200 GB).
The LTO4 tape drive also supports Write Once, Read Many (WORM) secure
media. This non-erasable, non-rewritable media meets several compliance
regulations such as HIPAA, Sarbanes-Oxley, and SEC 17A-4.
Note: Encryption is only possible using LTO4 media, including LTO4
WORM media, with the HP LTO4 tape drive. If you insert LTO2 or LTO3
media, encryption will be disabled.
Interfaces
(Native rates)
The HP LTO4 drive supports up to 120 MB/s data transfer rates using Data
Rate Matching (DRM). This features allows the tape drive to dynamically
and continuously adjust the speed of the drive, from 40 to 120 MB/s for
maximum performance
Interface support for the HP LTO4 includes:
■ Ultra 320 Small Computer System Interface (SCSI)
■ 4 Giga-bits per second (Gbps) Fibre Channel
