DISASTER RECOVERY AT HIGH RELIABILITY IN A STORAGE CLUSTER

摘要

A storage grid is provided. The storage grid includes a first cluster, a second cluster, and a third cluster. Each of the first cluster, the second cluster and the third cluster is configured to store an amount of data ranging from a portion of a copy of the data to a full copy of the data. The first cluster has a full copy of data written to the first cluster and at least a partial copy of data written to the second and third cluster. The second cluster has a full copy of data written to the second cluster, and at least a partial copy of the data written to the first and third cluster. The third cluster has a full copy of data written to the third cluster and at least a partial copy of the data written to the first and second cluster. A method of storing data is also provided.

1. A method of storing data, comprising:
receiving a first data at one storage cluster of a storage grid, the storage grid comprising multiple storage clusters; and repeating the receiving and each storing operation with a second data, such that no one storage cluster of the storage grid has a full copy of the data and a full copy of the second data.
