Abstract
A data storage structure, comprising: a plurality of storage units, each comprising: a storage media; and a library executive configured to manage the storage media. The structure further comprises a buffer connected to a controller, the controller comprising: a host interface configured to receive the instruction from the host machine; an object aggregator configured to combine the plurality of data objects into a data segment; a persistent write buffer configured to store the data segment; a persistent map configured to identify a location of each of the plurality of objects in the data segment; an erasure coder configured to encode the data segment into an erasure code; a destager configured to transfer the data segment from the persistent write buffer to the storage media in a given storage unit; and a library controller configured to communicate with the library executive in the given storage unit.
