Write cache system and method for data chunk bypass and acknowledgment of write of data chunk

A computer program product residing on a non-transitory computer readable storage medium having a plurality of instructions stored thereon which, when executed by a processor, cause the processor to perform operations comprising:

• receiving, at a first computing device, a data chunk from a second computing device;
• determining whether the data chunk includes one of a first type of data and a second type of data;
• in response to determining that the data chunk includes the first type of data:
• storing the data chunk in a cache operatively coupled to the first computing device, wherein the cache includes a first storage device type,
• sending an acknowledgement of a successful write of the data chunk based upon, at least in part, a successful storing of the data chunk to the cache, and
• copying the data chunk from the cache to a second storage device type;
• in response to determining that the data chunk includes the second type of data:
• storing the data chunk in the second storage device type, wherein the data chunk bypasses the cache, and
• sending an acknowledgement of a successful write of the data chunk based upon, at least in part, a complete storing of the data chunk in the second storage device.

A computing system including a processor and a memory configured to perform operations comprising:

• receiving, at a first computing device, a first data chunk sent from a second computing device;
• determining whether the data chunk includes one of a first type of data and a second type of data;
• in response to determining that the data chunk includes the first type of data:
• storing the data chunk to a cache operatively coupled to the first computing device, wherein the cache includes a first storage device type,
• sending an acknowledgement of a successful write of the data chunk to the second computing device based upon, at least in part, a successful storing of the data chunk to the cache, and
• copying the data chunk from the cache to a second storage device type;
• in response to determining that the data chunk includes the second type of data:
• storing the data chunk in the second storage device type, wherein the data chunk bypasses the cache, and
• sending an acknowledgement of a successful write of the data chunk based upon, at least in part, a complete storing of the data chunk in the second storage device.
