Liqid Assigned Two Patents

Failover handling in modular switched fabric for storage systems
Liqid Inc., Lafayette, CO, has been assigned a patent (9,684,575) developed by Breakstone, Jason, Broomfield, CO, Long, Christopher R., Colorado Springs, CO, and Cannata, James Scott, Denver, CO, for a “failover handling in modular switched fabric for 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 Peripheral Component Interconnect Express, (PCIe) interface, and configured to store data and retrieve the data stored on associated storage media responsive to data transactions. The data storage system also includes processing modules each comprising one or more processors, where a first processor is configured to receive data transactions and transfer the data transactions for delivery to associated ones of the storage drives. A monitoring system is configured to identify when the first processor fails, and responsively instruct a second processor to handle further data transactions directed to storage drives associated with the first processor.“

The patent application was filed on June 23, 2015 (14/747,368).

Power handling in scalable storage system
Liqid Inc., Lafayette, CO, has been assigned a patent (9,678,910) developed by Breakstone, Jason, Broomfield, CO, and Long, Christopher, Colorado Springs, CO, for a “power handling in a scalable storage system.“

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 assembly is provided. The data storage assembly includes a plurality of storage drives each comprising a PCIe host interface and solid state storage media, with each of the storage drives configured to store and retrieve data responsive to storage operations received over an associated PCIe host interface. The data storage assembly includes a PCIe switch circuit coupled to the PCIe host interfaces of the storage drives and configured to receive the storage operations issued by one or more host systems over a shared PCIe interface and transfer the storage operations for delivery to the storage drives over selected ones of the PCIe host interfaces. The data storage assembly includes holdup circuitry configured to provide power to at least the storage drives after input power is lost to the data storage assembly.“

The patent application was filed on April 23, 2015 (14/694,578).
