Component

Description

NetBackup media server

Specifies a host that has NetBackup media server software and is a client to the ACS library software host.

The NetBackup ACS robotic daemon (acsd) formulates requests for mounts, unmounts, and inventories. An API then uses IPC communication to routes these requests to:

  • (UNIX) The NetBackup ACS storage server interface (acsssi). The requests are converted into RPC-based communications and sent to the ACS library software.

  • (Windows) the Oracle StorageTek LibAttach service. This service sends the requests to the ACS library software.

Oracle StorageTek LibAttach Service

Windows computers only

Specifies that Library Attach for Windows, an ACS library software client application, enables Windows servers to use the StorageTek Nearline enterprise storage libraries.

LibAttach provides the connection between Windows and ACS library software through a TCP/IP network.

Obtain the appropriate LibAttach software from Oracle. See the Veritas support Web site for the latest compatibility information.

The following ACS library software:

  • Automated Cartridge System Library Software (ACSLS)

  • Oracle StorageTek Library Station

Receives the robotic requests from NetBackup and uses the Library Management Unit to find and mount or unmount the correct cartridge on media management requests.

On compatible host platforms, you may be able to configure ACS library software and NetBackup media server software on the same host.

Library Management Unit (LMU)

Provides the interface between the ACS library software and the robot. A single LMU can control multiple ACSLS robots.

Library Storage Module (LSM)

Contains the robot, drives, or media.

Control Unit (CU)

Specifies that the NetBackup media server connects to the drives through device drivers and a control unit (tape controller). The control unit may have an interface to multiple drives. Some control units also allow multiple hosts to share these drives.

Most drives do not require a separate control unit. In these cases, the media server connects directly to the drives.

CAP

Specifies the Cartridge Access Port.
