Abstract
In general, the invention relates to a method for writing data to server submission queues in a storage controller. The method includes receiving an I/O request, where the I/O request includes a command, where the I/O request is associated with a vSQ, and where the vSQ appears to the client as a set of memory locations in memory operatively connected to a storage controller. The method further includes obtaining a vSQ ID associated with the vSQ, identifying a sSQ based on the vSQ and a vSQ-to-sSQ mapping, generating a submission queue entry comprising the command and the vSQ ID, and sending the submission queue entry to the storage controller, where the sSQ is located in the memory and where the storage controller is configured to place the submission queue entry in the sSQ.
