Systems and methods for implementing a horizontally federated heterogeneous cluster

摘要

Systems, methods, and computer-readable media for intelligent distribution of data in a storage cluster are described herein. An example method can include striping a volume across a plurality of storage nodes. For example, a plurality of logical blocks of the volume can be distributed to the storage nodes in relation to respective sizes of the storage nodes. Additionally, the method can include maintaining a cluster volume table (CVT) storing information regarding distribution of the logical blocks across the storage nodes. The CVT can include a plurality of entries, where each of the entries in the CVT can include information identifying a respective owner storage node of a respective logical block. Optionally, a factor can be used to determine a number of logical blocks distributed to a storage node for each stripe when striping the volume across the storage nodes.
