2-2 System Description 6-01337-04 Rev A
2- General Description The Scalar 10K is a tape storage library that can be configured as a single media or mixed media library. It can be expanded from a single module library to a multiple module library. The Scalar 10K automates the storage, retrieval, and control of LTO-1, LTO-2, LTO-3, LTO-4, Super DLT (SDLT), and 1/2inch tape cartridges. Cartridges are mounted and unmounted in tape drives using application software from the host without operator intervention.
System Configurations The Scalar 10K can be configured as a Capacity-On-Demand (COD) configuration, Customer-Specific configuration, or a Dual Aisle configuration. For more detailed information about each of the following configurations, refer to Chapter 3, System Configurations. Capacity-On-Demand Configuration In a COD configuration, you receive a fully-populated library but do not use all storage slots. This gives you room to expand in the future.
Modules The Scalar 10K consists of five different modules. For an example of the five different modules, see Figure 2-2 on page 2-8. The Control Module (CM) and Accessor Module (AM) are the fundamental building blocks and are required on every library. See Figure 2-1 on page 2-3. The Expansion Module (EM), Tower Module (TM), and Drive Module (DM) are feature modules and are added as requirements change. The optional EM extends the length of the aisle.
In a Dual Aisle configuration, a safety barrier is included, which allows for concurrent maintenance by trained service personnel. Refer to Dual Aisle Configurations on page 3-14. Expansion Module The EM extends the length of the aisle and allows the library to be expanded to accommodate additional drive and cartridge requirements. In a COD or Customer-Specific configuration, the Scalar 10K can include a maximum of three EMs.
Table 2-1 TM Capacity Media Type Cartridge Capacity LTO 660 SDLT 552 1/2-incha 552 a. The 1/2-inch media type is used in 3592-J1A/TS1120 tape drives. In a Dual Aisle configuration, two inside TMs are required between each AM or EM. Optionally, outside TMs can be attached to the EMs on the primary aisle and secondary aisle. Refer to Dual Aisle Configurations on page 3-14.
Figure 2-2 Top View of Scalar 10K Modules Internal Components Figure 2-3 on page 2-10 shows the inside of a Scalar 10K.
Tape Drives The Scalar 10K supports the following tape drives: • IBM LTO-2 LVD - SCSI • IBM LTO-2 FC Multimode • IBM LTO-3 FC Multimode • IBM LTO-4 FC Multimode • IBM 3592-J1A/TS1120 Drive firmware supports both re-writable and Write Once Read Many (WORM) cartridges. All tape drive types, excluding 3592-J1A/TS1120 tape drives, are enclosed in a Universal Drive Sled (UDS) chassis.

Storage Assembly A storage assembly (Figure 2-4) is a modular storage assembly that contains tape cartridges. The AM and EM have four attachment areas called racks. Each rack can contain storage assemblies. See Figure 2-5 on page 2-12. Each linear media rack can support total slot capacities as indicated in Table 2-2 on page 2-12. Figure 2-4 Storage Assembly Each rack is divided into five sections counting from top to bottom as shown Figure 2-5 on page 2-12.

The 1/2-inch media type is used in 3592-J1A/TS1120 tape drives.
Cartridge Accessor The cartridge accessor (Figure 2-6 on page 2-13) identifies and moves cartridges between the storage cells, tape drives, and I/E stations. The cartridge accessor has: • A gripper assembly containing a cartridge gripper and the barcode scanner. The gripper is designed to pivot horizontally 180º, get and put cartridges in storage cells, tape drives, or the I/E station. The gripper fingers are designed to have full range control for open/close to handle different media types.
Tape Cartridges The Scalar 10K automates the retrieval, storage, and control of LTO, SDLT, and 1/2-inch cartridges. Note Duplicate barcode labels (even with different media identifiers) are NOT supported. Two characters are used to identify the cartridge type. For LTO, SDLT, and 1/2-inch cartridges, the media identifier is embedded at the end of the barcode label. All code 39 labels are supported. Refer to the Scalar 10K Operator Guide for more information on label types supported by the Scalar 10K.

Connectivity The Scalar 10K 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, network attachment, along with SCSI. SAN Connectivity The Scalar 10K can be connected to a Fibre Channel Storage Area Network (SAN) via the Storage Network Controller (SNC). See Figure 2-8 on page 2-17.
Figure 2-8 September 2007 Indirect Fibre Channel Attachment Connectivity 2-17
SCSI Connectivity The Scalar 10K library can be directly connected to one or two SCSI buses. See Figure 2-9. Because each SCSI bus is independent, it can be Single Ended or Differential. Both ends of each bus must be terminated. A terminator is shipped with each SCSI adapter card ordered. The minimum configuration of a Scalar 10K library requires one SCSI adapter. The SCSI type (Single Ended or Differential) must be specified at the time of order.
Scalar DLC The Scalar 10K, through its Scalar Distributed Library Control (Scalar DLC) interface, provides the industry’s most advanced combination of management and diagnostics. It creates and maintains the Scalar 10K configuration, the physical location of the cartridge accessor, and the inventory of cartridges. The database is kept in flash memory of the Library control hardware. The Scalar DLC attaches to the library SCSI bus.
Figure 2-10 Scalar DLC Network Attachment Redundant Servers The redundant Scalar DLC Integrated Controller for the Scalar 10K Dual Aisle library consists of Scalar DLC 2.5 or later software loaded on two rack-mountable servers. Each Server has Dual SCSI drives that are connected to an embedded RAID controller, 512MB memory, an LVD SCSI card for library connection, and redundant AC power supplies. In addition, each server operates with Windows Advanced Server with Microsoft Cluster Server (MSCS).
Together, these independent servers create a "server cluster." The cluster appears to users as a single server. Should the primary server fail, the secondary (passive) server automatically takes over all Scalar DLC functions. The systems also ships with a rack-mountable flat panel LCD monitor/keyboard/mouse, a rack-mountable KVM switch, a rack-mountable external RAID subsystem, and required system cabling. See Figure 2-11.
Remote Library Management The factory installed Remote Management Unit (RMU) in each system uses a standard web browser for remote library access. The supported browsers are: • Microsoft Internet Explorer version 5.0 and above • Netscape Navigator version 4.01 for Unix and 4.
