Options

●Manual Cartridge Use. Individual cartridges can easily be transported to the drives through the Mailbox.

●Cartridge Pre-Check. Whenever you power up your Scalar Library the Media Picker will scan the cartridge storage slots and build a log of valid cartridge locations. Sensors in the Mailbox allow a similar mapping of the area.

●Reverse Cartridge Protection. The cartridge storage slots, and the slots in the Mailbox employ a design that prevents the cartridges from being inserted incorrectly.

●Downloadable Firmware. Both your Scalar Library and the DLT drives employ Flash EEPROM technology permitting easy on-site installation of firmware updates from the host computer.

●Built-in Diagnostics. Your Scalar Library includes diagnostic firmware that tells you when drive head cleaning is required, reports diagnostic results, and drive operating status. Embedded data logging of operational embedded and drive errors embedded aid you in failure analysis.

DLT Drives

Your adic library can be equipped with second-, third-, or fourth-generation DLT drives. All drive models (DLT2000XT, DLT4000, and DLT7000) can read and write 2.6 GB, 6.0 GB, and 10.0 GB tape formats for 100% interchange compatibility with earlier DLT drives. Tape density is selectable by the application software or a button on the drive.

Maximum Capacity and Sustained Transfer Rates

Differential SCSI

Differential SCSI is available for the robotics. The drives can be all differential, all single-ended, or a mix of both.
