Selective Storage Presentation (SSP)

For links and interfaces common to all Configuration Wizards links, please see Wizards Overview in ACU help.

Note: The Selective Storage Presentation link option will only be available for controllers that support it.

Warning: Logical drives should not be accessed by more than one server running an operating system that was not designed to share logical drives.

Consult your operating system documentation for more information.

Selective Storage Presentation (SSP) allows logical drives on an array controller to be shared by multiple servers. A server connects to the array controller by using a host controller that is installed in the server. SSP allows users to name connections from host controllers to array controllers, and it allows users to grant or deny access to connections for each logical drive. SSP is currently only supported for fibre channel controllers.

Depending on the type of array controller you have, SSP can either be enabled/disabled on a logical drive basis or on a controller basis.

Note: If a controller that previously had SSP enabled for any Host Bus Adapter(HBA) then has all of its logical drives that were selected to grant access deleted, and this state is successfully saved, SSP will automatically be disabled for that controller.

RAID Array 4x00 Controllers
If you have a RAID Array 4x00 Controller, SSP is enabled or disabled on a logical drive basis. Disabling SSP for a logical drive means that access to that logical drive is unrestricted. If you enable SSP for a logical drive, you will be able to restrict access to the logical drive.

All Remaining Controllers
For all other controllers that support SSP, SSP is enabled or disabled on a controller basis. Disabling SSP for a controller means that access to all logical drives on the controller is unrestricted. If you enable SSP for the controller, you will be able to restrict access to the logical drives on the controller.

Disable
This radio button allows you to turn off SSP so all connections will have access to the logical drive. This means that all servers with host controllers connected to the array controller will be able to access the logical drive.

Enable
This radio button allows you to turn on SSP to control access to the logical drive. Select this option if you want to select which connections will have access to the logical drive.

If you have chosen to Enable SSP you will have the option to set SSP access settings for the logical drive and rename connections.

This screen allows you to set up Connection Names for all connections from servers to the array controller. Type in the connection name you want in the appropriate text box. Renaming a connection will name that connection for all logical drives on the controller.

Also, this screen allows you to select which connections will have access to the logical drive. Check the connections to grant the connections access to the logical drive. Uncheck the connections to deny the connections access to the logical drive. If you uncheck all connections, the logical drive will be not be accessible.

This screen displays the following details about the connections:

  • Connection Name
    A user-defined name for a connection from a server to an array controller. This connection uses a host controller that is installed in the server. The connection name is a convenient way to identify a connection for a controller instead of relying entirely on the Adapter ID of the host controller.
  • Host Mode
    A user-defined setting that allows the user to choose the Host Mode of a Host Bus Adapter identified by the controller. The Host Mode setting helps to control the behavior of the controller with respect to the Host Bus Adapter.
    Note: The Host Mode option will only be available for controllers that support it.
  • Adapter ID
    A unique identification code for a host controller that is printed on the controller. This is also called a World-Wide Name (WWN).
  • Location
    Displays the location of the connection. It can be any of the following:
    • Local - the host controller is located in the local server (the server that the ACU is currently running on).
    • Remote - the host controller is located on a remote server.
    • Unknown - the location of the host controller is unknown.

  • Status
    Displays the status of the connection. It can be any of the following:
    • Online - the host controller is currently connected to the array controller.
    • Offline - the host controller is currently not connected to the array controller.
