Using a standby data storage system to detect the health of a cluster of data storage servers
First Claim
1. A method of using a standby data storage system to detect a condition of a cluster of data storage servers that control changes to a primary data storage, said method comprising the computer-implemented steps of:
- designating one or more of said data storage servers with a status within said cluster;
encoding said status into log data that reports changes to said primary data storage performed by said cluster of data storage servers;
transmitting said log data with said encoded status from said primary data storage to said standby data storage system; and
determining, at said standby data storage system, an operating condition of said cluster of data storage servers based, at least in part, on said status.

Abstract
Detecting an operating condition in a multi-server data storage system. One or more of the data storage servers are designated with a status within the cluster. The designating may be performed by at least one of the data storage servers. The status is encoded into log data having records that report changes to the primary data storage performed by the cluster of data storage servers. The log data is transmitted from the primary data storage to the standby data storage system. The standby data storage system determines an operating condition of the cluster of data storage servers based, at least in part, on the status.

16. A computer readable medium carrying one of more sequences of instructions, wherein execution of the one or more sequences of instructions by one or more processors causes the one or more processors to perform a method of using a standby data storage system to detect an operating condition of a cluster of data storage servers that control changes to a primary data storage, said method comprising the steps of:
-
designating one or more of said data storage servers with a status within said cluster;
encoding said status into log data that reports changes to said primary data storage performed by said cluster of data storage servers;
transmitting said log data with said encoded status from said primary data storage to said standby data storage system; and
determining, at said standby data storage system, an operating condition of said cluster of data storage servers based, at least in part, on said status. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
