Abstract
A system comprises control circuitry that is operable to assign a first of a plurality of computing devices to serve file system requests destined for any of a first plurality of network addresses; assign a second of the computing devices to serve file system requests destined for any of a second plurality of network addresses; maintain statistics regarding file system requests sent to each of the first plurality of network addresses and the second plurality of network addresses; and reassign, based on the statistics, the first of the computing devices to serve file system requests destined for a selected one of the second plurality of network addresses.
Claims20
A system comprising:
- control circuitry distributed among a plurality of computing devices, wherein the control circuitry is operable to maintain statistics regarding file system requests,
- wherein prior to a network event:
- a first computing device of the plurality of computing devices is operable to serve a file system request to any of a first plurality of IP addresses of a set of IP addresses,
- a second computing device of the plurality of computing devices is operable to serve a file system request to any of a second plurality of IP addresses of the set of IP addresses, and
- a third computing device of the plurality of computing devices is operable to serve a file system request to any of a third plurality of IP addresses of the set of IP addresses,
- and wherein subsequent to the network event, based on the statistics, an elected coordinator of the plurality of computing devices is operable to:
- reassign the second computing device to serve file system requests destined for a first portion of the first plurality of IP addresses, wherein the reassignment is according to a ranking of the first plurality of IP addresses, and wherein the ranking of the first plurality of IP addresses is according to a plurality of respective loads on the first plurality of IP addresses, and
- reassign the third computing device to serve file system requests destined for a second portion of the first plurality of IP addresses,
- and wherein a front end of the second computing device is configured to track statistics regarding file systems requests that the second computing device serves,
- and wherein the statistics tracked by the second computing device are independent of functionality of the first computing device.
