Introduction

Overview

The Seagate computer environments that require high-performance, extra-high-capacity data storage. Based on a 3.5-inch mechanism, the internal and external Scorpion 240 autoloaders provide 20 Gbytes of data-storage capacity per cartridge (40 Gbytes compressed) for a total of 240 Gbytes (compressed) per six-cartridge magazine. The drive has a native transfer rate of 2.75 Mbytes per second, 5.5 Mbytes per second compressed.

The Scorpion 240 drive combines established DAT technology, high-density recording and hardware data-compression capability, along with Seagate’s proven computer-grade design to provide unmatched reliability and performance characteristics among DDS products. The Scorpion 240 is ideal for server and network/enterprise applications such as:

• Backup of high-capacity networks and disc arrays

• Network and internet servers

• Automated storage management

• Online, unattended data collection

• Near-line secondary storage for text, graphics or multimedia information

• Archival storage

Scorpion

240 digital data storage (DDS) autoloader is designed for

DDS Format Standard Compatibility

The Scorpion 240 drive supports the DDS-4, DDS-3, DDS-2 and DDS recording formats. Compatibility with each of these standards ensures complete write and read interchange of recorded digital data between all compliant drive and media vendors.

Note: The Scorpion 240 can use 90-meter DDS-1 media but not 60-meter DDS-1

media.

The Scorpion 240 drive supports DDS data compression, effectively doubling storage capacity and transfer rates.

The Scorpion 240 drive complies with the following guidelines and specifications:

• The DDS recording format standard, ANSI/ECMA-139,

Tape Cartridge for Information Interchange - Helical Scan Recording - DDS Format.

3,81mm Wide Magnetic

(native)

Note: 60-meter DDS tape cannot be used with the Scorpion 240. In data-compression mode, the Seagate Scorpion 240 drive typically doubles the

storage capacity and transfer rate of the native uncompressed operation. Tape capacity and sustained data-transfer rate are dependent upon the characteristics of the files being compressed, along with system parameters such as the speed of the host, the operating system and the application software used. The Scorpion 240 drive also offers synchronous or asynchronous SCSI transfers with a high-speed burst data-transfer rate of 80 Mbytes per second.

The Scorpion 240 provides superb reliability through three levels of error-correction code (ECC) and the four-head design, which provides for read-after-write (RAW) error detection and correction. The Scorpion 240 also includes a “flying” preamplifier for greater signal-to-noise ratio.

Introduction

Features

The Scorpion 240 DDS drive represents Seagate’s commitment to engineering reliable and durable tape drive products that implement leading-edge technology. Key features of the drive include:

• Platform based on state-of-the-art drive mechanism and tape handling

components sealed in a dust-free enclosure.

• Two models available: 5.25-inch full-height internal drive (STDL42401LW) and

external subsystem with built-in auto-sensing, worldwide power supply (model (STDL62401LW))

• ANSI/ECMA compliance and capability to write and read DDS-4, DDS-3, DDS-2,

and DDS cartridges. (The Scorpion 240 can use 90-meter DDS-1 media but not 60-meter DDS-1 media).

• Advanced onboard DDS-DC hardware using Data Compression Lempel-Ziv

(DCLZ) data-compression algorithm

• High-speed transfer rates for fast backups:

– 2.75 Mbytes per second typical—uncompressed data – 5.5 Kbytes per second typical—compressed data

• High-performance SCSI burst transfer rate of 10 Mbytes per second

asynchronous and 80 Mbytes per second synchronous

• Flash memory to store setup parameters and enable field firmware upgrades

• Four-head design with RAW error detection and rewrites

• Three levels of ECC to ensure data integrity

• Uncorrectable error rate of less than 1 in 10

• Custom Seagate-designed LSI circuitry to reduce component count and boost

drive reliability

• LVD / Ultra Wide SCSI connection

• Automatic power-on self-test

• Support for TapeAlert™ Certified Solutions
