Abstract
A system and associated methodology for sharing a common data storage medium in a computer cluster is hereafter disclosed. Each server within the cluster includes a processor, an operating system, a stand-alone file system and a cluster management system. Moreover, the data storage medium is configured to store data usable by each of the servers within the server cluster. The cluster management system communicates with each stand-alone file system to coordinate access among the plurality of servers to the data storage medium.
Claims19
A system for shared data access, comprising:
- a plurality of servers configured into a server cluster wherein each server includes a processor, an operating system, a stand-alone file system, and a cluster management system;
- and
- a data storage medium configured to store data and coupled to each of the servers within the server cluster wherein the cluster management system communicates with each stand-alone file system to coordinate access among the plurality of servers to the data storage medium.
A method for data access to a shared data storage medium among a plurality of servers in a server cluster, the method comprising:
- identifying one or more storage devices associated with the shared data storage medium;
- enumerating the identified storage devices associated with the shared data storage medium;
- coordinating between the plurality of servers in the sever cluster exclusive access to each identified storage device;
- and
- isolating access to the one or more storage devices to only an actively engaged server within server cluster.
