Introduction
28 MSA1000 Reference Guide
Selective Storage Presentation (SSP)
SSP permits sharing of the MSA1000 storage between servers, including servers
running different operating systems.
Each logical drive on the controller has an Access Control List (ACL) that
contains the worldwide names of the server host adapters that have access to the
drive. If a server tries to send commands to a logical drive that it does not have
access to, the firmware will reject the command.
The SSP maps the worldwide names of server host adapters to connection names
and sets up ACLs for logical drives based on these worldwide names.
SSP can be set up and managed through the ACU and the CLI.
The following diagram illustrates an SSP scenario.
