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 Overview 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, 3,81mm Wide Magnetic Tape Cartridge for Information Interchange - Helical Scan Recording - DDS Format. 2 · Scorpion 240 Product Manual The DDS-DC recording format standard, ANSI/ECMA-150, 3,81mm Wide Magnetic Tape Cartridge for Information Interchange - Helical Scan Recording DDS-DC Format using 90 m length tapes. The DDS-2 recording format standard, ANSI/ECMA-198, 3,81mm Wide Magnetic Tape Cartridge for Information Interchange - Helical Scan Recording - DDS-2 Format using 120 m Length Tapes. The DDS-3 recording format standard, ANSI/ECMA-236, 3,81mm Wide Magnetic Tape Cartridge for Information Interchange - Helical Scan Recording - DDS-3 Format using 125 m Length Tapes. The DDS-4 recording format specification from ECMA-288: 3,81 mm Wide Magnetic Tape Cartridge for Information Interchange - Helical Scan Recording: DDS-4 Format. Note: For the latest ECMA standards, see the ECMA web site at http://www.ecma.ch · · · Scorpion 240 Capacity and Transfer Rates The Scorpion 240 provides the following capacities and transfer rates, depending on recording mode and tape length: Recording Mode DDS Tape length Capacity (native) Capacity (compressed) Transfer rate (native) 90 meters 2.0 Gbytes 4 Gbytes 915 Kbytes/sec DDS-2 120 meters 4.0 Gbytes 8 Gbytes 915 Kbytes/sec DDS-3 125 meters 12.0 Gbytes 24 Gbytes 2.75 Mbytes/sec DDS-4 150 meters 20.0 Gbytes 40 Gbytes 2.75 Mbytes/sec 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 3 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).

This specification includes all power-on and operational time but excludes maintenance periods. Operational time is assumed to be 30 percent of the power-on time. Operational time is the time the tape is loaded on the cylinder (tape moving and/or cylinder rotating). Note. The MTBF rating does not represent any particular drive, but is derived from a large database of test samples. Actual rates may vary from unit to unit. Mean Time to Repair The mean time to repair (MTTR) is the average time required by a qualified service technician to diagnose a defective drive and to install a replacement drive. The MTTR for DAT products is less than 0.5 hour (30 minutes). The Seagate DDS drives are field-replaceable units. If a problem occurs with a subassembly or component in the drive, you should replace the entire unit. Return the drive to the factory in its original packaging. Contact your distributor, dealer, your computer system company or your Seagate sales representative to arrange the return. DDS Cartridge Specifications DDS drives provide maximum data integrity and reliability when Seagate-qualified DDS cartridges are used as the recording media. Seagate maintains an ongoing program to qualify manufacturers of DDS cartridges. The following cartridges are recommended: · · · · DDS-2 data cartridge: model M34000, 120-meter tape DDS-3 data cartridge: model STDM24G, 125-meter tape DDS-4 data cartridge: model STMD40, 150-meter tape DDS-4 cleaning cartridge: model 90301 Use only a Seagate-qualified DDS-4 cleaning cartridge with the Scorpion 240 to avoid damaging the drive. Note. Contact your Seagate sales representative for information on qualified DDS data and cleaning cartridge manufacturers and models. Specifications 11 Regulatory Compliance These DDS drives comply with the regulations listed in the following table. Agency CSA TUV-RHEINLAND UL FCC CE Regulation C22.2, No. 950-M89 EN 60 950 1950 Class A and Class B1 CE compliance 1. Required compliance for external model; verification on file for internal models. Use these drives only in equipment where the combination has been determined to be suitable by an appropriate certification organization (for example, Underwriters Laboratories Inc. or the Canadian Standards Association in North America). You should also consider the following safety points: · · Install the drive in an enclosure that limits the user's access to live parts, gives adequate system stability and provides the necessary grounding for the drive. Provide the correct voltages (+5 VDC and +12 VDC) based on the regulation applied--Extra Low Voltage (SEC) for UL and CSA and Safety Extra Low Voltage for BSI and VDE (if applicable).
