US 8,285,849 B2 · Storage and service provisioning for virtualized and geographically dispersed data centers

Abstract

Geographically dispersed data centers each include servers and storage systems and are in communication with each other. An application is installed on a guest operating system on a virtual machine set up on a server at a first data center. The application accesses a logical unit on a storage system at the first data center. When migration of the application is initiated, the process determines whether any of the data centers has server resources and storage resources required to receive migration of the application. A destination data center is selected from candidate data centers meeting requirements for migration of the application. The application and guest operating system are migrated from the first data center to a second virtual machine set up on a second server at the destination data center. If a replica of the LU is not already present at the destination data center, the LU is also replicated.

Dependent claims

At least one management server for controlling a plurality of dispersed data centers, each management server comprising a processor, a memory, and a manager being configured to:

set and manage replication relations between a storage area of a storage system of a first data center and a storage area of a storage system of a second data center;
maintain said replication relations by said plurality of dispersed data centers;
replicate data used by an application executed on a first server of said first data center to said storage system of said second data center;
check if there are sufficient server resources in said second data center;
maintain relationships between the storage area of said first data center and applications using the storage area of said first data center;
and
migrate said applications using the storage area of said first data center to said second data center so that the applications can be executed in said second data center.

4 more elements

A non-transitory computer-readable storage medium storing a plurality of instructions for controlling a data processor to control a plurality of dispersed data centers, the plurality of instructions comprising:

instructions that cause the data processor to set and manage replication relations between a storage area of a storage system of a first data center and a storage area of a storage system of a second data center;
instructions that cause the data processor to maintain said replication relations by said plurality of dispersed data centers;
instructions that cause the data processor to replicate data used by an application executed on a first server of said first data center to said storage system of said second data center;
instructions that cause the data processor to check if there are sufficient server resources in said second data center;
instructions that cause the data processor to maintain relationships between the storage area of said first data center and applications using the storage area of said first data center;
and
instructions that cause the data processor to migrate said applications using the storage area of said first data center to said second data center so that the applications can be executed in said second data center.
