Method and apparatus for web based storage on-demand

摘要

A distributed virtual SAN infrastructure provides a scalable dynamically expandable virtual storage service pool to a plurality of host systems. The storage service pool is created via execution of a virtual storage automatic construct protocol and provides storage volume (space) to each of the host systems in on-demand base. The distributed virtual SAN infrastructure includes one or more SAN units including IP SAN unit and Fiber Channel SAN unit, at least one management console, one distributing control system across a network infrastructure, where the network infrastructure provides the communication links between all systems in the distributed virtual SAN infrastructure.

主权项

1. A control server comprising:
at least one processor, one network interface, and program code configuring the control server to control automatically constructing a plurality of service pools by controlling execution of a service pool construction protocol between the control server and each of a plurality of servers connected across a network infrastructure, the controlling execution of the service pool construction protocol comprising:
receiving a packet from a first one of the servers, the packet informing the control server that the first one of the servers is going online upon the first one of the servers being brought online;storing, via the packet received, identification of the first one of the servers for organizing the service pools, andsending an enquiring packet back to the first one of the servers for requesting information of a specific service that the first one of the servers will deliver;receiving a response packet from the first one of the servers, the response packet comprising detailed information of the specific service deliverable by the first one of the servers,
assigning the first one of the servers to a first one of the service pools according to the deliverable specific service, andupdating the stored information of the first one of the servers for the service pools by including the assignment of the first one of the servers in respect to the detailed information about the specific service obtained from the response packet.
