METHOD AND APPARATUS FOR SEAMLESS MANAGEMENT FOR DISASTER RECOVERY
First Claim
1. A management server coupled to processor devices and storage devices, comprising:
- means for storing storage device information relating to the storage devices;
means for storing mapping information between application programs executed by the processor devices and portions of storage implemented in the storage devices being utilized by the application programs;
means for receiving a command specifying a first application program executed by a first processor device, from the application programs and the processor devices;
means for specifying a first storage portion in a first storage devices from the storage devices, based on the mapping information; and
means for specifying a candidate storage portion(s) in a candidate storage device(s) from the storage devices, based on the storage device information,wherein the candidate storage portion(s) is capable to store replica of data in the first storage portion.
