  • System and method for partitioning a computer system into domains
    Patent number: 6961761
    Abstract: A domain partitioning system for a multi-node computer system is disclosed. An external server manager is coupled to a domain configuration unit by a dedicated sideband channel. The server manager has write privileges to the domain configuration unit that allows the server manager to control the domain partitioning and the routing tables. None of the domains of the computer system are permitted write access to the domain configuration unit. In one embodiment, the domain configuration unit is a set of domain partition registers and routing table registers coupled to a system interconnect.
    Type: Grant

  • Method and system for logical partitioning of cache memory structures in a partitoned computer system
    Patent number: 6754776
    Abstract: A system and method of logically partitioning shared memory structures between computer domains is disclosed. In one embodiment, each domain is assigned a unique address space identifier. The unique address space identifier preferably has tag extension and index extension bits. This permits the tag and index bits of a conventional local domain address to be extended with tag extension and index extension bits. Data entries in the shared memory structure may be accessed using an extended index value. Hits may be determined using an extended tag value.
