US 2018/0121133 A1 · SYSTEMS AND METHODS FOR RANDOM TO SEQUENTIAL STORAGE MAPPING

Abstract

Systems and methods for mapping random data writes to sequential or semi-sequential storage. Data writes may be initially directed to an SSD or other relatively low latency and high IOPS data storage layer. The data may remain in the SSD storage layer until a group of data may be written, together, to a sequential or semi-sequential storage layer. A data organizer may group the data into data buckets based on tags and/or policies associated with the data. In this way, data subject to similar lifetime, priority, data protection, and/or other policies may be stored on a same segment or other portion of the sequential storage layer. Similarly, data having similar access patterns, authors, files, objects, or project affiliations, may be stored together on a same segment of the sequential storage layer.

Dependent claims

A data storage system comprising:

a first storage layer comprising a first type of storage device;
a second storage layer comprising a second type of storage device different from the first type;
an I/O manager directing incoming write requests to the first storage layer;
and
a data organizer:
organizing the data stored on the first storage layer into data buckets, wherein a data bucket comprises data having at least one similar attribute;
and
when a data bucket reaches a quota, moving the data in the bucket from the first storage layer to the second storage layer.
