Does the RHEL6 kernel support the dm-switch target?

Issue

• The RHEL7 kernel contains a new device-mapper target called "switch"
• Is this target also part of the RHEL6 kernel?
• The dm-switch target is created to take advantages of sending I/O requests to a node where the data is stored to avoid I/O forwarding. The storage system and architecture like EqualLogic and Nimble Storage, where volume could be spanned across several nodes, can use the module to achieve optimized performance.
• However, the RHEL 6 distributions does not come with the dm-switch target.
