Appl. No.:

09/513655

Inventors:

Robert J. Block - Mountain View CA
James G. Hanko - Redwood City CA
J. Kent Peacock - Menlo Park CA

Assignee:

Sun Microsystems, Inc. - Palo Alto CA

International Classification:

G06F 15173

US Classification:

709226, 709229

Abstract:

The present invention provides a method and apparatus for distributing load in a multiple server computer environment. In one embodiment, a group manager process on each server periodically determines the servers capacity and load (i. e. , utilization) with respect to multiple resources. The capacity and load information is broadcast to the other servers in the group, so that each server has a global view of every servers capacity and current load. When a given terminal authenticates to a server to start or resume one or more sessions, the group manager process of that server first determines whether one of the servers in the group already is hosting a session for that user. If that is the case, one embodiment of the present invention redirects the desktop unit to that server and the load-balancing strategy is not employed. Otherwise, for each resource and server, the proper load balancing strategies are performed to identify which server is best able to handle that particular session.

US Classification:

709229, 709212, 709217, 709219, 714 4

Abstract:

A cluster implements a virtual disk system that provides each node of the cluster access to each storage device of the cluster. The virtual disk system provides high availability such that a storage device may be accessed and data access requests are reliably completed even in the presence of a failure. To ensure consistent mapping and file permission data among the nodes, data are stored in a highly available cluster database. Because the cluster database provides consistent data to the nodes even in the presence of a failure, each node will have consistent mapping and file permission data. A cluster transport interface is provided that establishes links between the nodes and manages the links. Messages received by the cluster transports interface are conveyed to the destination node via one or more links. The configuration of a cluster may be modified during operation.

Abstract:

Improved techniques for managing operations of clustered computing system are disclosed. The improved techniques provide protection against potential problems encountered in operation of clustered computing. More particularly, the improved techniques can be implemented as an integral solution that provide protection against undesired partitions in space and partitions in time. The improved techniques do not require any human intervention.

International Classification:

G06F 15/16
G06F 12/00

US Classification:

709203, 709219

Abstract:

The present invention provides a method and apparatus for making a computational service highly available in a multiple server computer environment. In the thin client computing paradigm, end user terminals rely on remote server computers for operation of most functions traditionally associated with personal computing. If the remote server computer fails, all of the users' computers will likewise fail. The present invention provides a solution by implementing a redundant server strategy and a redirection process. One or more servers hosting a communication to the terminal do not contain the only copy of permanent user data. This makes all session hosting servers interchangeable. If a server fails, the failure is detected and the terminal switches to another host server.
