| 发明名称 | Replicating cache nodes in a cluster | ||
| 摘要 | A method and apparatus for replicating instances of cache nodes in a cluster is described. In one embodiment, the number of available cache nodes in the cluster is determined. Available cache nodes from the cluster are selected based on a parameter. An instance of a cache node is replicated to only one of the selected cache nodes in the cluster. | ||

| 主权项 | 1. A method comprising: identifying an instance of a first cache node in a pool in a cluster; nominating a second cache node to participate in the pool in the cluster to replicate the first cache node; selecting the second cache node to participate in the pool in the cluster in view of a parameter, wherein the parameter indicates that the second cache node is located on a different physical rack than the physical rack of the first cache node; determining a failure of the first cache node; initiating a state transfer to the second cache node in view of the failure of the first cache node; and replicating the instance of the first cache node to the second cache node in view of the state transfer. | ||
