Selective Storage Presentation
SSP is a controller firmware feature that enables the administrator to control access
from multiple hosts to logical drives on the Smart Array Cluster Storage system. The
administrator selects which server host or hosts can access the stored data, restricting
access as needed to assure data integrity and security.
Each logical drive on the controller has an access control list that contains the IDs of
the server host adapters that have access to the drive. If a server attempts to send
commands to a logical drive without access authority, the controller rejects the
command.
The configuration utility maps the IDs of server host adapters to connection names
and sets up access control lists for logical drives based on the adapter IDs.
SSP Hardware Configurations
To configure the hardware for SSP, use SCSI cables to connect each server to the
2-Port or 4-Port Shared Storage Module installed in the storage system. Boot
volumes for individual servers can reside on server drives or storage system drives.
Enabling SSP
After choosing the configuration that best suits your needs, enable SSP with
ACU Version 6.0 or later. Locate ACU on the SmartStart CD. For instructions, refer
to the HP Array Configuration Utility User Guide on the Documentation CD.
