Insert/Eject Station The I/E Station allows for the insertion and ejection of cartridges without interrupting the normal operation of the library. The I/E Station uses two different cartridge magazines. One magazine has a capacity of six half-inch cartridges (3590/ DLT/SDLT/LTO), the other magazine has a capacity of nine 8 mm (AIT) cartridges. A maximum of two magazines of any type can be present in the I/E Station at any time. If you have two different magazines in an I/E Station, such as one halfinch and one 8 mm magazine, the library requires Scalar DLC. For more information on Scalar DLC, refer to Scalar DLC Option on page 2-11 or contact an ADIC representative. The coordinate for the rows in the old style I/E Station is always contiguous (1 to 12 for half-inch and 1 to 18 for 8 mm). Since two magazines of different cartridge types can be present in the I/E station at any time, the first cell of the bottom magazine of the new style I/E station always starts with Row 10. 22 June 2004 Internal Components 2-7 Connectivity The Scalar 1000 offers several different connectivity options, allowing the library to support a wide range of backup topologies and applications. Flexible library connectivity delivers active support for loop and switched fabric Fibre Channel protocols, along with SCSI. SAN Connectivity The Scalar 1000 can be connected to a Fibre Channel Storage Area Network (SAN) via the Storage Networking Controller (SNC). The SNC provides four parallel SCSI bus connections, one ethernet, and two Fibre Channel connections. The SNC allows native SCSI devices (for example: robot controller and tape drives) to be seen by any hosts that are attached to the SAN. The library controller and the tape drives access the SAN via the SNCs that can be installed in a Scalar 1000 CM or EM. See Figure 2-2 on page 2-9. 2-8 System Description 6-01150-01 Rev A Figure 2-2 Storage Networking Fibre Channel Attachment (Through an SNC) 22 June 2004 Connectivity 2-9 SCSI Connectivity The Scalar 1000 can be directly connected to one or two SCSI buses. Because each SCSI bus is independent, it can be Single Ended, High Voltage Differential, or Low Voltage Differential. Both ends of each bus must be terminated and a terminator is shipped with each SCSI adapter card ordered. The minimum configuration of a Scalar 1000 library requires one SCSI adapter and the SCSI type (Single Ended, High Voltage Differential or Low Voltage Differential). Although the Scalar 1000 can be attached to a wide SCSI bus, it is not a wide SCSI device and its SCSI ID must be in the range of 0 to 7. See Figure 2-3. Figure 2-3 Direct SCSI Attachment 2-10 System Description 6-01150-01 Rev A Scalar DLC Option The Scalar 1000, through its optional Scalar Distributed Library Control (Scalar DLC) interface, provides the industry's most advanced combination of management and diagnostics. The Scalar DLC software serves as a centralized library management tool that simplifies and automates the tracking and management of all system resources for optimal performance and maximum availability. The Scalar DLC attaches to the library SCSI bus. The host continues to directly attach to the drives through a SCSI or a Fibre Channel Interface. For more information on Scalar DLC, including detailed information on the supported interfaces, refer to ADIC Scalar DLC documentation.
