Congestion mitigation in a distributed storage system
First Claim
1. A system comprising:
- a local computing device communicatively coupled to a plurality of remote computing devices via one or more network links, wherein the local computing device and the plurality of remote computing devices have a file system distributed among them;
a file system request buffer on the local computing device; and
file system choking management circuitry on the local computing device, wherein the file system choking management circuitry is operable to control;
a data batch timing setting;
a data batch size setting;
a metadata batch timing setting;
a metadata batch size setting;
a first rate at which a first type of file system requests are fetched from the file system request buffer, wherein the first type of file system requests comprises requests to read data from the file system and requests to write data to the file system, wherein the file system choking management circuitry is operable to control the first rate according to an adjustment of a first batch size setting; and
a second rate at which a second type of file system requests are fetched from the file system request buffer, wherein the second type of file system requests comprises requests to read metadata from the file system and requests to write metadata to the file system.

Abstract
A system comprises a plurality of computing devices that are communicatively coupled via a network and have a file system distributed among them, and comprises one or more file system request buffers residing on one or more of the plurality of computing devices. File system choking management circuitry that resides on one or more of the plurality of computing devices is operable to separately control: a first rate at which a first type of file system requests (e.g., one of data requests, data read requests, data write requests, metadata requests, metadata read requests, and metadata write requests) are fetched from the one or more buffers, and a second rate at which a second type of file system requests (e.g., another of data requests, data read requests, data write requests, metadata requests, metadata read requests, and metadata write requests) are fetched from the one or more buffers.
