Balanced Transfers on Interfaces

A data storage device, comprising:

• a memory device;
• and
• a controller coupled to the memory device, wherein the controller comprises:
• a host interface module (HIM) comprising a re-ordering buffer and a completion and interrupt sync module, wherein the HIM is configured to maintain a first interface between the controller and a first host device, wherein the HIM is configured to maintain a second interface between the controller and a second host device;
• a flash interface module (FIM) coupled to the memory device;
• and
• a command scheduler coupled between the HIM and FIM, wherein the controller is configured to:
• balance traffic between the first host device and the second host device, wherein the balancing comprises ensuring that the first interface and the second interface are saturated.

A data storage device, comprising:

• means to store data;
• and
• a controller coupled to the means to store data, wherein the controller is configured to:
• receive a transaction packet from the means to store data;
• classify the transaction packet;
• place the transaction packet in a queue of a plurality of queues;
• send the transaction packet to a host device;
• and
• maintain saturation on an interface between the controller and the host device and interfaces between the controller and other host devices.
