Scalable low-latency storage interface

A method to control communication between a set of virtual functions (VB) and a media management system (MMS), the method comprising:

• consolidating commands from the set of VFs and dynamically allocating write buffers (WBs) from a set of available WBs to the set of VFs using the commands using a command queue manager circuit;
• for each VF in the set of VFs:
• managing a submission queue (SQ) for a respective VF from the set of VFs, and receiving a command from the respective VF, including one or more submission queue entries (SQEs), using a VF submission queue circuit;
• and
• managing a list of pending writes for the respective VF and coordinating the one or more received SQEs with allocated WBs using a VF write buffer list (WBL) circuit;
• managing WB access for the set of VFs and providing write data to the MMS using a WB access circuit;
• allocating a first plurality of WBs to receive multiple logical blocks of data of a first SQE;
• receiving a first logical block of data of the first SQE at a first WB and providing the first logical block of data to the first allocated WB;
• and
• providing, using the first allocated WB, the first logical block of data to the MMS before all of the multiple logical blocks of data of the first SQE are received and provided to the allocated first plurality of WBs.

At least one non-transitory machine-readable medium including instructions that, when executed by processing circuitry of a host interface circuit, cause the host interface circuit to control communication between a set of virtual functions (VFs) and a media management system (MMS), including to:

• consolidate commands from the set of VFs;
• dynamically allocate write buffers (WBs) from a set of available WBs to the set of \Ts using the commands;
• for each VF in the set of VFs;
• manage a submission queue (SQ) for a respective VF from the set of VFs;
• receive a command from the respective VF, including one or more submission queue entries (SQEs);
• and
• coordinate the one or more received SQEs with allocated WBs;
• and
• manage WB access for the set of VFs and provide write data to the MMS using the allocated WBs
• allocate a first plurality of WBs to receive multiple logical blocks of data of a first SQE;
• receive a first logical block of data of the first SQE at a first WB and provide the first logical block of data to the first allocated WB;
• and
• provide, using the first allocated WB, the first logical block of data to the MMS before all of the multiple logical blocks of data of the first SQE are received and provided to the allocated first plurality of WBs.
