Scalable data using rdma and mmio

A computerized method for storing data in a memory mapped input/output (MMIO) enabled storage device of a control server communicatively coupled with a client device through a remote direct memory access (RDMA) enabled network interface controller (rNIC), the method comprising:

• receiving through a first communication protocol from the client device a first data block for storing on the storage device;
• receiving through the first communication protocol from the client device a first entry for a submission queue, the first entry for communicating using a second communication protocol;
• receiving through the first communication protocol from the client device a second entry for a send queue to send a second data block from a memory reserved for the client device to the client device over the first communication protocol;
• and
• receiving a trigger in response to receiving the second entry, and sending the second data block to the client device using the first communication protocol.

A non-transitory computer readable medium having stored thereon instructions that when executed by one or more processing elements perform a method of retrieving data from a memory mapped input/output (MMIO) enabled storage device of a control server communicatively coupled with a client device through a remote direct memory access (RDMA) enabled network interface controller (rNIC), the method comprising:

• receiving from the client device, through a first communication protocol, a first entry for a submission queue, the first entry using a second communication protocol that permits communication between the control server and the MMIO enabled storage device;
• receiving from the client device, through the first communication protocol, a second entry for a send queue, the second entry using the first communication protocol to send a data block from a memory reserved for the client device to the client device;
• receiving a trigger for the first entry;
• and
• receiving, using the second communication protocol, the data block from the MMIO enabled storage device in response to executing the first entry;
• and
• transmitting, using the first communication protocol, the data block to the client device in response to the data block being received from the MMIO enabled storage device.

A server including:

• a remote direct memory access (RDMA) enabled network interface controller (rNIC) configured to communicate with a client using a first communication protocol and to communicate with a storage device using a second communication protocol;
• and
• a memory configured to store a data block received from the storage device using the second communication protocol,
• wherein the rNIC is further configured to transmit the data block stored in the memory to the client device using the first communication protocol.

A server including:

• a remote direct memory access (RDMA) enabled network interface controller (rNIC) configured to communicate with a client device using a first communication protocol and to communicate with a storage device using a second communication protocol, the storage device including a memory reserved for the client device;
• a memory configured to store a first data block that is for storing on the storage device, in response to the rNIC receiving the data block from the client device;
• a submission queue configured to store a first entry in response to receiving the first entry from the client device, the first entry facilitating communication between the rNIC and the storage device using the second communication protocol;
• a send queue configured to store a second entry in response to receiving the second entry from the client device, the second entry facilitating sending a second data block from the memory reserved for the client device to the client device over the first communication protocol;
• and
• a doorbell configured to send the second data block to the client device using the first communication protocol in response to being triggered.
