Abstract: Replicating database elements in an InfiniBand® architecture subnet includes a master subnet manager function updating database elements of an InfiniBand® architecture subnet. A replicated set of the database elements is created at each of a set of standby subnet managers using the InfiniBand® architecture subnet. A standby subnet manager included in the set of standby subnet managers assumes the master subnet manager function after the master subnet manager function has been relinquished. The standby subnet manager included in the set of standby managers that assumes the master subnet manager function uses the replicated set of the database elements to manage the InfiniBand® architecture subnet.

Abstract: InfiniBand architecture subnet management includes providing an InfiniBand architecture subnet (200) with a master subnet manager function (206) managing the InfiniBand architecture subnet (200), where the master subnet manager function is located at a first node (202) of the InfiniBand architecture subnet. An active general service manager function (208) manages a service (214, 218) within the InfiniBand architecture subnet, where the active general service manager function is located at the first node. The master subnet manager function migrates to a second node (204) and the active general service manager function as well as the active managers migrate to the second node to co-locate with the master subnet manager function.

Abstract: A method and apparatus for selecting a limited number of standby subnet managers includes providing an InfiniBand architecture subnet (100, 200, 300, 400, 500, 600) having a plurality of nodes (102), where each of the plurality of nodes has a priority value (307, 308) and a globally unique identifier (309, 310). Each of the plurality of nodes includes a subnet manager (305, 306). Each of the plurality of nodes is ranked according to the priority value and the globally unique identifier. The subnet manager is selected to be one of a set of standby subnet managers (328) based on the priority value and the globally unique identifier of each of the plurality of nodes.

Abstract: Replicating database elements (808) in an InfiniBand architecture subnet (800) includes a master subnet manager function (806) updating database elements of an InfiniBand architecture subnet. A replicated set (830) of the database elements is created at each of a set of standby subnet managers (832) using the InfiniBand architecture subnet. A standby subnet manager (824, 826) included in the set of standby subnet managers assumes the master subnet manager function after the master subnet manager function has been relinquished. The standby subnet manager included in the set of standby managers that assumes the master subnet manager function uses the replicated set of the database elements to manage the InfiniBand architecture subnet.
