ABSTRACT:
A data storage system includes an input/output server and a storage unit. The input/output server includes a processor, memory, and a host channel adapter. The storage unit includes a processor, memory, and a storage module. The storage module includes a storage controller, and an interface block for connecting the storage module to a corresponding memory-mapped interface. The storage unit further includes a host channel adaptor. The storage unit host channel adapter is connected to a corresponding memory-mapped interface. The storage unit host channel adapter is capable of remote direct memory access to the input/output server. Protocol translation logic is configured to intercept a memory access request from the storage controller, and initiate a corresponding remote direct memory access to the input/output server through the storage unit host channel adapter and the input/output server host channel adapter.
