Introduction

Prahlad Purohit is a notable inventor based in Sunnyvale, California. He has made significant contributions to the field of storage systems, holding three patents that showcase his innovative techniques and methodologies.

Latest Patents

One of his latest patents is titled "Space savings reporting for storage system supporting snapshot and clones." This invention efficiently determines accurate storage space savings reported to a host connected to a reference-counted storage system that employs de-duplication and compression. The storage space savings relate to snapshots and/or clones supported by the storage system. The snapshot or clone may be represented as an independent volume, either as a read-only copy (snapshot) or a read-write copy (clone) of a parent volume. The metadata is organized as multi-level dense trees, with volume metadata entries for storing the metadata. Space adjustment counters, such as clone space adjustment (CSA) and diverged space adjustment (DSA) counters, are employed to determine the storage space savings.

Another significant patent is "Shared dense tree repair." This invention involves a consistency checker configured to perform repairs to multi-level dense tree metadata structures shared between volumes managed by a volume layer of a storage input/output (I/O) stack. The consistency checker verifies and repairs on-disk structures of the volume layer according to a distributed repair procedure that maintains consistency properties across all volumes in a volume family.
