Abstract
Techniques are provided for storing data and metadata on sharded storage arrays. In one embodiment, data is processed in a sharded distributed data storage system that stores data in a plurality of shards on one or more storage nodes by providing a plurality of addressable virtual shards within each of the shards, wherein at least a first one of the addressable virtual shards stores the data, and wherein at least a second one of the addressable virtual shards stores the metadata related to the data; obtaining the data from a compute node; and providing the data and the metadata related to the data stored to the sharded distributed data storage system for storage in the respective first and second addressable virtual shards. The metadata related to the data is stored together at a portion of a corresponding stripe for the data in the second one of the addressable virtual shards. A third one of the addressable virtual shards optionally stores a checksum value related to the data.
