# 1 Product Overview

Oracle's StorageTek SL150 Modular Tape Library is a rack mounted automated tape library with a capacity of 30 to 300 LTO Ultrium tape cartridges (tapes) with 1 to 20 half-height LTO-5 or LTO-6 Fibre Channel (FC) or Serial Attached SCSI (SAS) tape drives (see Figure 1-1).

## General Information

The minimum library configuration consists of a 3U (133.4 mm, 5.25 inches) base module, designated Module 1, with one robotic hand, a mailslot, a power supply, and one tape drive (with an option to add a second tape drive and a second power supply). Tapes reside in a removable 15-cartridge magazine on each side of the module. Up to three tape slots of the base module left magazine can be designated as reserved slots to store diagnostic or cleaning tapes.

The external interface for library control is provided by a bridged tape drive. The robot control is a SCSI Medium Changer device appearing as LUN 1 on a tape drive. The base module is the smallest fully functional library.

The library can be expanded from one to ten modules. A 2U (88.9 mm, 3.5 inches) expansion module provides the library an additional capacity of 30 tapes and up to two tape drives. Expansion modules are designated Module 2 through Module 10. Modules provide two 15-cartridge magazines, slots for up to two tape drives, and slots for up to two power supplies.

A graphical user interface (GUI) provides local or remote role-based access control for the library.

- A library is remotely managed by entering the hostname or IP address into a web browser (such as Chrome, Firefox, or Safari). An example of the remote interface is shown in Figure 1-2.

  The library information is presented as a graphical representation. Module 1 shows the tape slots in the left magazine, tape slots in the right magazine, and available tape drives between the magazines. The mailslot resides above the right magazine while the robot is above the left magazine. The magazine representation has identifiers for column number and row number. There is a separate image for each module in the library.

- The base module front control panel has an LCD touch screen panel (operator panel) which provides basic information about the library (see Figure 1-1). The touch screen is designed for use as an information point rather than a tool for maintenance.

  The front control panel touch screen is also used to perform basic initialization setup (defining a default administrator password, setting the library date and time, and performing network configuration of Port 1). Additional library management functions are performed by the administrator using the remote interface.

The library can be divided into a maximum of two partitions with each having a bridged tape drive in the base module. Each partition behaves as an independent library, but all partitions share the use of the single robot, reserved slots, and mailslot.

## Class 1 Laser Product Notice

The StorageTek SL150 Modular Tape Library contains a class-1 laser as defined by IEC 60825-1 Ed. 2 (2007).

Warning: Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.

## Library Status Indicators

Library status indicators are located on the front control panel above the left cartridge magazine (see Figure 1-3) and at the rear of the library on the robot customer replaceable unit [CRU] in the dark rectangle to the left of the robot lock (see Figure 3-1).

Figure 1-3 Library Status Indicators (Front Control Panel)

- Fault: a fault anywhere in the library triggers the fault LED. Look for active fault indicators on other CRUs.

- OK: indicates an operational library.

  When both the Fault and OK indicators are active at the same time, the library is in a degraded state.

## Customer Replaceable Units

The SL150 Modular Tape Library customer replaceable units (CRUs) are:

- Front control panel

- Tape cartridge magazines

- Robot

- Tape drive

- Power supply

- Expansion module controller

- Base module chassis

- Expansion module chassis (Module 2 through 10)

### CRU Indicators and Controls

Each customer replaceable unit (CRU) has status indicators.

Note: The indicators are powered by main power. If the library is turned off, all indicators are turned off.

- Locate Library LED: aids in identification of the specific tape library in need of attention. The LED is enabled locally or through the remote interface.

- Front Control Panel (see Figure 1-1 near the upper left corner of the touch screen):

  Fault: indicates a failure anywhere in the front control panel CRU.

  OK: functioning properly.

- Robot (see Figure 3-1):

  Fault: indicates a failure anywhere in the robot CRU.

  OK: functioning properly.

  - Robot Lock (see Figure 3-21): Secures the robot at the top of the base module after the robot is either parked or manually raised. You must lock the robot before removing it or when replacing an expansion module CRU.

- Power Supply (see Figure 3-10):

  Fault: indicates a power supply failure.

  OK: functioning properly.

- Tape Drive (see Figure 3-8):

  Locate: this LED is on when enabled through the remote management interface to prepare the tape drive for removal from the library.

  Fault: indicates a drive tray failure.

  OK: functioning properly.

  Port 1 activity (FC and SAS tape drives)

  Port 2 activity (SAS tape drives and LTO-6 FC tape drive)

  Encryption status

  Encryption reset: a push button switch to reset the tape drive to a default IP address.

- Module Controller (see Figure 3-18):

  Fault: a fault anywhere in the module controller (KLE card) triggers the fault LED and turns off the OK LED for that specific controller (a library can have up to nine module controllers).

  OK: functioning properly.
