Abstract
Embodiments of the invention provide methods and systems of managing a file access, in a distributed file system environment. In the provided methods and systems, each of the host computers is connected with one of the file servers as a target file server and issues the file access request to the target file server, for access to a target file stored in at least one of the file servers. The management computer collects load information from the file servers, analyzes it, by specifying location of the target file and the target file server, and based on the analysis, redistributes the target file among the file servers and reallocates connections between the host computers and the target file servers.
Claims19
A method of managing a file access, in a system which comprises a plurality of host computers, a network, and a plurality of file servers, respectively storing at least one or more files, wherein each of the host computers is connected with a target file server associated with the each of the host computers via the network, and issues a file access request to the target file servers, for access to a target file stored in one of the file servers, comprising the steps of:
- collecting a load information from the file servers;
- analyzing the load information, by specifying location of the target file and the target file server;
- redistributing the target file among the file servers;
- and
- reallocating connection between the host computers and the target file servers.
A system comprising:
- a plurality of host computers;
- a network;
- a plurality of file servers, connected with the host computers via the network, the file servers respectively storing at least one or more files;
- and
- a management computer communicated with the host computers and the plurality of file server via the network;
- wherein each of the plurality of host computers is configured to issue a file access request to a target file server, for access to a target file stored in one of the plurality of file server,
- wherein the management computer is configured to collect a load information from the file servers,
- wherein the management computer is configured to analyze the load information, by specifying location of the target file and the target file server, wherein the management computer is configured to redistribute the target file among the file servers, and
- the management computer is configured to reallocate connections between the host computers and the target file servers.
