Liqid Inc., Lafayette, CO, has been assigned a patent (9,798,636) developed by Breakstone, Jason, Broomfield, CO, Long, Christopher R., Colorado Springs, CO, and Cannata, James Scott, Denver, CO, for a "front end traffic handling in modular switched fabric based data storage systems."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "Systems, methods, apparatuses, and software for data storage systems are provided herein. In one example, a data storage system is provided that includes storage drives each comprising a PCIe interface, and configured to store data and retrieve the data stored on associated storage media responsive to data transactions received over a switched PCIe fabric. The data storage system includes processors configured to each manage only an associated subset of the storage drives over the switched PCIe fabric. A first processor is configured to identify first data packets received over a network interface associated with the first processor within a network buffer of the first processor as comprising a storage operation associated with at least one of the plurality of storage drives managed by a second processor, and responsively transfer the first data packets into a network buffer of the second processor.

The patent application was filed on June 23, 2015 (14/747,450).
