Title: The Innovations of Darrell D E Long
Introduction
Darrell D E Long is a notable inventor based in Soquel, California. He has made significant contributions to the field of computing, particularly in filesystem management. With a total of 5 patents to his name, his work has had a considerable impact on how data is managed and accessed in modern computing environments.
Latest Patents
One of his latest patents is titled "Managing filesystem versions." This invention provides a system and method for managing logical versions of a filesystem through a near-instantaneous copy process. Each logical version, including the primary version, is assigned a unique epoch number, and each filesystem object is assigned two epoch numbers that define the space of logical versions for which the object exists. A version table maintains a list of all valid epoch numbers, ensuring that original states of previous logical filesystem versions are preserved.
Another significant patent is the "Method, system and computer program product for implementing copy-on-write of a file." This invention presents various copy-on-write implementations for a computing environment. One implementation employs a read mapping table for virtual block to physical block mapping during read operations, while a different write mapping table is used for writing modified blocks. This innovation allows for efficient copy-on-write operations, even in distributed client-server environments.
