Abstract:
A method, computer program product, and computing system for receiving, at a host computing device, a request to copy data from a source Non-Volatile Memory Express (NVMe) namespace directly accessible by a source storage controller to a destination NVMe namespace directly accessible by a destination storage controller and may determine whether the destination storage controller can directly access the source NVMe namespace. In response to determining that the destination storage controller cannot directly access the source NVMe namespace, a first identifier associated with the data may be generated via the source storage controller. The first identifier may be provided to the host computing device. A data handle associated with the first identifier may be generated via the destination storage controller. The data may be copied, via the destination storage controller, from the source NVMe namespace to the destination NVMe namespace based upon, at least in part, the data handle.
