Method and apparatus for web based storage on demand

摘要

Rapid demanding for storage capacity at internet era requires a much flexible and powerful storage infrastructure. Present invention disclosed a type of storage system based a model of centrally controlled distributed scalable virtual machine. In this model, one or more service pools including virtual storage service pool and application service pools can be automatically created to meet the demands for more storage capacity from various applications. Specially this model provide a solid foundation for distributing storage volumes for supporting storage on-demand and sharing with exceptional management capabilities. In addition, this model provides a flexible fault recovery topology beyond the traditional recovery plan.

主权项

1. A computing system implementing a topology for fault recovery, the computing system comprising:
a plurality of storage servers and a plurality of hosts interconnected across a network infrastructure; wherein the storage servers are organized to have a plurality of mirrored pairs, each of which operable delivering storage service to one of the hosts, and
wherein at least a first one of the storage servers is configured as a first spare storage server for delivering fault replacement service to a first one of the mirrored pairs whenever a fault occurred to one of mirrored storage servers in the first one of the mirrored pairs; and wherein each of the hosts is configured for access to at least one of the mirrored pairs, and
wherein the hosts are configured with at least a first spare host and two or more non-spare hosts among the hosts, the first spare host being configured for delivering fault replacement service to the two or more non-spare hosts whenever a fault occur to a first one of the two or more non-spare hosts while the first one of the two or more non-spare hosts access to storage service delivered by the first one of the mirrored pairs.
