Cisco Assigned Four Patents

Migrating logical volumes from thick provisioned layout to thin provisioned layout
Cisco Technology, Inc., San Jose, CA, has been assigned a patent (11,385,947) developed by Lawrence, Nivin, Rao, Sandesh K., Fremont, CA, Veerachamy, Manikandan, Milpitas, CA, Chandra, Amit, Sinha, Tushar, San Jose, CA, Kumar, Manoj, Fremont, CA, and Duffey, David W., Austin, TX, for “migrating logical volumes from a thick provisioned layout to a thin provisioned layout.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “The present disclosure is directed to migrating logical volumes from a thick provisioned layout to a thin provisioned layout, and includes one or more processors and one or more computer-readable non-transitory storage media comprising instructions that, when executed by the one or more processors, cause one or more components of the system to perform operations comprising creating an abstraction layer on top of a logical volume in a storage device, the abstraction layer for accessing the logical volume, the logical volume one of a plurality of logical volumes in a volume group of the storage device, allocating a thin pool from remaining storage space in the volume group of the storage device, creating a snapshot of the logical volume, adding a thin virtual volume corresponding to the logical volume to the thin pool, and copying data from the snapshot to the thin virtual volume.”

The patent application was filed on November 24, 2020 (17/103,061).

Multi-tenant optimized serverless placement using smart network interface cards and commodity storage
Cisco Technology, Inc., San Jose, CA, has been assigned a patent (11,381,526) developed by Mestery, Kyle Andrew Donald, Woodbury, MN, and Wells, Ian James, Milpitas, CA, for “multi-tenant optimized serverless placement using smart network interface cards and commodity storage.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Multi-tenant optimized serverless placement using network interface card and commodity storage may be provided. A first request to execute a first function may be received. Next, it may be determined to execute the first function at a first network interface card. The first network interface card may include a plurality of processors. Then, a container may be created at the first network interface card. The container may have at least one processor of the plurality of processors. The first function may be executed at the container.”

The patent application was filed on May 8, 2019 (16/406,872).

Efficient distribution of peer zone database in FC fabric
Cisco Technology, Inc., San Jose, CA, has been assigned a patent (11,381,524) developed by Subramani, Karthik, Tummala, Venu Gopal, and Uppunda, Kishan Kumar Kotari, Karnataka, India, for an “efficient distribution of peer zone database in fibre channel fabric.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Provided are techniques for the efficient distribution of peer zone databases in a FC Fabric. In an example, a switch instantiates a peer zone definition defining a peer zone in which two or more initiator host devices are each permitted to communicate with one or more target storage devices via the switched FC fabric and the two or more initiator host devices are prevented from communicating with each other. The switch stores the peer zone definition in a peer zone database at the FC switch, and distributes the peer zone definition to other FC switches of the switched FC fabric without performing a Fabric lock operation.”

The patent application was filed on July 17, 2020 (16/931,730).

Tenant-level sharding of disks with tenant-specific storage modules to enable policies per tenant in distributed storage
Cisco Technology, Inc., San Jose, CA, has been assigned a patent (11,354,039) developed by George, Johnu, Zhang, Kai, Udupi, Yathiraj B., San Jose, CA, and Dutta, Debojyoti, Santa Clara, CA, for a “tenant-level sharding of disks with tenant-specific storage modules to enable policies per tenant in a distributed storage systemc.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Embodiments include receiving an indication of a data storage module to be associated with a tenant of a distributed storage system, allocating a partition of a disk for data of the tenant, creating a first association between the data storage module and the disk partition, creating a second association between the data storage module and the tenant, and creating rules for the data storage module based on one or more policies configured for the tenant. Embodiments further include receiving an indication of a type of subscription model selected for the tenant, and selecting the disk partition to be allocated based, at least in part, on the subscription model selected for the tenant. More specific embodiments include generating a storage map indicating the first association between the data storage module and the disk partition and indicating the second association between the data storage module and the tenant.”

The patent application was filed on May 20, 2020 (16/879,612).
