First Claim
Patent Images
1. A method comprising:
- determining, by congestion management circuitry of a distributed electronic storage system (DESS), an amount of congestion in the DESS;
controlling, by data migration circuitry of the DESS, migration of data stored in a first tier of storage of the DESS to a second tier of storage of the DESS based on;
the amount of congestion in the DESS;
characteristics of the data; and
characteristics of the first tier of storage.

Abstract
A distributed electronic storage system (DESS) comprises congestion management circuitry and data migration circuitry. The congestion management circuitry is operable to determine an amount of congestion in the DESS. The data migration circuitry is operable to control migration of data stored in a first tier of storage to a second tier of storage based on the amount of congestion in the DESS, characteristics of the data, and characteristics of the first tier of storage.
