US 2018/0004667 A1 · FUNCTIONAL CACHING IN ERASURE CODED STORAGE

Abstract

Encoding a file into a plurality of chunks, wherein a subset of the plurality of chunks may be used to create a functional equivalent of the file. At least one additional chunk is created from the plurality of chunks. The at least one additional chunk is directed to be stored in a cache memory and the plurality of chunks are directed to be stored on at least one storage node. Upon demand for the file, at least one additional chunk is cased to be retrieved from the cache and at least a portion of the plurality of chunks are caused to be retrieved from the at least one storage node and the functional equivalent of the file is constructed through utilization of the at least one additional chunk and the portion of the plurality of chunks.

Dependent claims

An apparatus comprising:

a processor;
and
memory coupled to the processor, the memory comprising executable instructions that cause the processor to effectuate operations comprising:
encoding a file into a plurality of chunks wherein a subset of the plurality of chunks may be used to create a functional equivalent of the file;
creating at least one additional chunk from the plurality of chunks;
directing the at least one additional chunk to be stored in a cache memory and the plurality of chunks to be stored on at least one storage node;
upon demand for the file, causing the at least one additional chunk to be retrieved from the cache;
and
constructing the functional equivalent of the file through utilization of the at least one additional chunk and the portion of the plurality of chunks.
