Data device grouping across data storage device enclosures for synchronized data maintenance

摘要

Techniques for operating a storage front-end system are disclosed. The techniques include identifying a synchronous group of data storage devices across two or more enclosures, each of which comprise a plurality of data storage devices. Data across the data storage devices is accessible by a storage front-end system as an aggregate memory space. The techniques further include sending an activation request to the enclosures to synchronously activate the data storage devices in the synchronous group and performing a data maintenance task in the aggregate memory space of the data storage devices.

1. A method of operating a storage front-end system, comprising:
identifying a deduplication group of data storage devices across two or more enclosures, wherein each of the enclosures comprises a plurality of data storage devices, wherein data across the data storage devices is accessible by the storage front-end system as an aggregate memory space; queuing a deduplication task; determining that the deduplication group should be activated based, at least in part, on a cyclical schedule; in response to determining that the deduplication group should be activated, transmitting a request to the enclosures to synchronously activate the data storage devices; receiving an indication from each of the enclosures indicating that the data storage devices have been activated; and in response to receiving the indications from each of the enclosures, dequeuing the deduplication task; and
deduplicating at least a portion of the data in the aggregate memory space.
