• SA_ID - An index (into the SA table) that is passed in the CT command descriptor to indicate
which Access Control Record (containing the key is being used to encrypt/decrypt the
command data) to use in the SA table.
• Master Security Client (MSC) - Upon first discovery, an MSC will configure the first ACG,
granting itself client access and all of the systems it wants to manage server access. Once
security is enabled on a server system, that server cannot grant itself client access. Only an
MSC can grant this access to a server by creating an Access Sub Group (ASG) and making a
server the client to the ASG.
• ACG - An ACG consists of a client system and the servers it is allowed access to manage. An
MSC creates an initial ACG. All additional ACGs are defined out of this initial ACG.
• ASG - A sub-group of systems created from the systems of a client’s ACG. One system is the
designated client and the others are made servers. The updates to the SA files are sent from the
client to the appropriate systems to create an ASG. The new client system not only has access
to remotely manage the servers in its new ACG, but and can also create additional ASGs from
its own systems in its ACG. This gives the ASG a hierarchical nature:
• Backup Master - The system designated by an MSC as the backup MSC. It can take over the
MSC if the MSC becomes permanently disabled and can no longer be the MSC.
