ADIC 7000DLT, 4000 installation and operation guide Overview, Model DLTTape DLTTape Iiixt

Overview

This section of the document provides a physical description of the switches, indicators and connectors on the front and rear panels of the 4000/7000DLT Series. Additional information describes other requirements (additional hardware and/or software) needed to utilize the 4000/7000DLT Series.

Description

The 4000/7000DLT Series consists of two models, the DLTTM4000 and the DLTTM7000. They are all SCSI-2 compatible, high performance, streaming tape cartridge data storage devices designed for storage of near-line and off-line data. All models use data compression, compaction, and Digital Linear Tape (DLT) to obtain the capacities shown in Table 2-1. The 4000/7000DLT Series are equipped with a 2- line by 20-character backlit LCD display. The LCD displays drive status messages, error messages, and drive Power-On Self-Test (POST) results messages.

Table 2-1	Maximum Capacity
Model	DLTTape III	DLTTape IIIXT	DLTTape IV
4000DLT	10 GB (native)	15 GB (native)	20 GB (native)
	20 GB (compressed)	30 GB (compressed)	40 GB (compressed)
7000DLT	10 GB (native)	15 GB (native)	35 GB (native)
	20 GB (compressed)	30 GB (compressed)	70 GB (compressed)

The 4000/7000DLT Series are equipped with a 5 1/4 inch form factor, half-inch tape drive. The design includes a dual- channel read/write head, Digital Lempel-Ziv (DLZ) high- efficiency data compression, and tape mark directory to maximize data throughput and minimize data access time.

Used for unattended backups or archiving, the 4000/7000DLT Series allows you to back up a higher data capacity at higher speed than either 8mm or 4mm DAT-based drives. Table 2-2 lists the maximum compressed mode transfer rates of the two models:
