Cirrus Data Assigned Two Patents

Inserting virtual storage layer in fibre channel based SAN
Cirrus Data Solutions, Inc., Syosset, NY, has been assigned a patent (9,792,076) developed by Lam, Wayne K., Lam, Wai T., Jericho, NY, Tam, Yikshum, Roslyn Heights, NY, and Zhu, Lin, Jericho, NY, for a “systems, devices, apparatus, and methods for transparently inserting a virtual storage layer in a fibre channel based storage area network while maintaining continuous input/output operations.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method of transparently inserting a virtual storage layer into a Fibre channel based storage area network, (SAN) while maintaining continuous I/O operations is provided. A device is inserted between a host entity and a first storage device. The device identifies a plurality of first paths between the host entity and the first storage device, and defines a plurality of second paths by defining, for each first path among the plurality of first paths, a corresponding second path between the host entity and a second storage device. The device determines, for each of the plurality of first paths, a respective first state. The device establishes, for each of the second paths among the plurality of second paths, a second state based on the first state of the corresponding first path. The device redirects, to the second storage device, communications directed from the host entity to the first storage device, via the plurality of second paths.”

The patent application was filed on October 31, 2016 (15/339,438).

Identifying stored data by device located in path between virtual FC switches
Cirrus Data Solutions, Inc., Syosset, NY, has been assigned a patent (9,740,649) developed by Lam, Wai, Lam, Wayne, Jericho, NY, and Liu, Chang, Wuhan, China for a “systems, devices, apparatus, and methods for identifying stored data by a device located in a path between virtual Fibre channel switches and performing a data management service.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A first port of a device is connected to a first switch port of a first virtual switch defined within a switch device and a second port of the device is connected to a second switch port of a second virtual switch defined within the switch device. A target world wide port name of a target port of a storage system connected to the second virtual switch is identified by the device. The first port of the device is registered, in a first registration procedure, with the first virtual switch based on the target world wide port name. Registration information relating to an initiator port of a server that is associated with the target port is received in a second registration procedure. An initiator world wide port name of the initiator port of the server is determined based on the registration information. A storage volume in the storage system that is associated with the initiator port is identified based on the initiator world wide port name of the initiator port.”

The patent application was filed on September 29, 2016 (15/280,925).
