Title: Alan David Brunelle: Innovator in Storage Solutions

Introduction

Alan David Brunelle is a notable inventor based in Merrimack, NH (US). He has made significant contributions to the field of storage solutions, holding a total of 3 patents. His work focuses on enhancing data integrity and efficiency in clustered filesystems.

Latest Patents

One of his latest patents is a fully active and non-replicated block storage solution. This innovation provides techniques for implementing cache coherency in a clustered filesystem. In this system, data blocks are stored in the cache of each host node, allowing for efficient data management. When a client device requests to write data blocks to a shared storage device, the system ensures that the data is stored in the cache of the host node. A notification is then sent to other host nodes to invalidate any cached copies of the data blocks, maintaining data integrity.

Another significant patent by Brunelle is related to persistent reservation IO barriers. This method allows multiple computers to share a storage device while ensuring data integrity. A computer registers for reserved access by storing its identifier in the storage device. If the registered computer loses knowledge of its identifier, it can replace it with a new one, ensuring continued access and data integrity.

Career Highlights

Brunelle has worked with prominent companies in the technology sector, including Hewlett-Packard Development Company, L.P. and Oracle International Corporation. His experience in these organizations has contributed to his expertise in storage solutions and data management.
