Abstract
A storage controller receives data from a host. The data is provided to a storage stack on the storage controller. The storage stack can perform deduplication, compression or file layout operations on the data, which is then written to a first storage unit coupled to a first port of the storage controller. The storage controller determines whether a second port of the first storage controller is configured as a remote port. In response to determining that the second port is configured as a remote port, the data is also provided to a pass-thru stack on the first storage controller. The pass-thru stack performs protocol conversion on the data and writes the data to the second port on the storage controller.
