Selective Storage Presentation
SSP is a controller firmware feature that enables the administrator to control access
from multiple hosts to logical drives on the MSA500 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.
