ADIC Libraries Attached to Scalar Distributed Library Controller (SDLC) - Prerequisites

Table of Contents

Software Requirements

The following software versions are supported for the various components:

Component Software Version
Scalar Distributed Library Controller (SDLC) 2.5
DAS Client software 3.12
ADIC library ADIC 1000 (or above)

The media changer should be attached to the computer in which the SDLC software is installed. Depending on your configuration some or all the drives may be attached to this computer. If the library is shared among several MediaAgents, you must install the DAS Client software on all the MediaAgent computers in which the library will be configured.

Hardware Configuration

Within a CommCell group, depending on the environment, the MediaAgents can be configured to access the ADIC library controlled by a Scalar Distributed Library Controller (SDLC) using one of the following configurations:

  • Direct-attached library configuration.
  • Dynamic Drive Sharing (DDS) configuration in the SAN environment.

Direct-Attached Library Configuration

The SDLC is connected to the library’s media changer with a direct SCSI. Each MediaAgent communicates with SDLC through the TCP-IP port. In addition, each MediaAgent must also be attached to the drive(s) in the library using SCSI ports.

Within the library, some or all drives must be assigned to the MediaAgents for exclusive use by the CommCell group. The unassigned drives will be available for other applications or another CommCell group.

The following diagrams provide an overview of the hardware configuration required for configuring the ADIC library using SDLC:

DDS Configuration

In a DDS configuration, the SDLC is connected to the library’s media changer with a direct SCSI. Each MediaAgent in the CommCell group communicates with the SDLC and the drives in the library through the following:

  • MediaAgent to Bridge/ Router/ Gateway using SCSI ports
  • Bridge/ Router/ Gateway to a SAN switch using Fibre Channel cable.
  • SAN switch is connected to all the drives in the library using Fibre Channel cables.

The following diagram provides an overview of the hardware configuration required for sharing an ADIC library among multiple MediaAgents with DDS configuration.
