1. A method, comprising:
- providing an InfiniBand architecture subnet having a plurality of nodes, wherein each of the plurality of nodes has a priority value and a globally unique identifier;
providing each of the plurality of nodes with a subnet manager;
ranking each of the plurality of nodes according to the priority value and the globally unique identifier; and
selecting if the subnet manager is included in a set of standby subnet managers based on the priority value and the globally unique identifier of each of the plurality of nodes.

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.
