Title: Raghavan Devanathan: Innovator in Data Storage Solutions

Introduction

Raghavan Devanathan is a notable inventor based in Bengaluru, India. He has made significant contributions to the field of data storage systems, holding a total of four patents. His work focuses on enhancing communication adapters and buffer management in storage systems.

Latest Patents

One of Raghavan's latest patents is titled "Guaranteed delivery in receiver side overcommitted communication adapters." This invention involves receiving an input/output (I/O) request that includes a data stream from a host processor. The network adapter of a storage controller manages the storage for the host processor. The storage controller features a storage buffer to temporarily hold data before it is migrated to the storage. It also includes a data cache. The invention determines whether the storage buffer has sufficient free space to accommodate the incoming data stream. If there is enough space, the data stream is stored in the storage. Conversely, if space is limited, the data stream is stored in the data cache.

Another significant patent is "Buffer credit management in a data storage system." This invention introduces buffer over-commit logic that calculates a buffer over-commit value based on the average duration of I/O operations and the cumulative lifespans of a set of buffers. The logic can determine the buffer over-commit value in various ways, including being proportional to the difference between average I/O operation duration and buffer lifespan.
