Abstract
Device, system, and method of storage controller having simulated volumes. For example, an apparatus for data storage management includes: a storage controller to manage access to one or more physical volumes, the storage controller including a simulation module to simulate access to one or more simulated volumes.
Claims21
A system comprising:
- a storage controller for managing access to at least one physical volume and at least one simulated volume, the storage controller comprising:
- an interceptor module to intercept a command from a host and determine if the command is to be executed by a physical volume or by a simulated volume;
- and
- a simulation module to simulate access to the at least one simulated volume and to simulate at least one characteristic of a physical volume.
1 more element
A method comprising:
- intercepting a command;
- determining if the command is to be executed by at least one physical volume or by at least one simulated volume;
- and
- simulating access to at least one simulated volume if the command is to be executed by a simulated volume and simulating at least one characteristic of a physical volume.
1 more element
A non-transitory computer program product comprising:
- a computer useable medium having computer usable program code embodied therewith, the computer usable program code comprising:
- computer usable program code configured to manage data storage, the computer usable program code comprising:
- computer usable program code configured to intercept a command from a host and determine if the command is to be executed by at least one physical volume or by at least one simulated volume;
- and
- computer usable program code configured to simulate access to at least one simulated volume if the command is to be executed by a simulated volume and simulate at least one characteristic of a physical volume.
