Patent ID: 7185025

Claim:
An InfiniBand architecture computer subnet, comprising: a master subnet manager function; database elements of the InfiniBand architecture computer subnet, wherein the master subnet manager function updates the database elements; a replicated set of the database elements; and a set of standby subnet managers, wherein the replicated set of the database elements is created at each of the set of standby subnet managers, wherein a standby subnet manager included in the set of standby subnet managers assumes the master subnet manager function, and wherein the standby subnet manager included in the set of standby subnet managers that assumes the master subnet manager function initializes the InfiniBand architecture computer subnet using the replicated set of the database elements wherein the replicated set of database elements comprises a service record and wherein the service record comprises a lease time, wherein the master subnet manager function converts the lease time to a first end time, wherein the master subnet manager function converts the first end time to a remaining time, wherein the standby subnet manager included in the set of standby subnet manager converts the remaining time and a local time at the standby subnet manager included in the set of standby subnet managers.
