Introduction

John H. Howard is a notable inventor based in San Jose, California. He has made significant contributions to the field of data storage technology, holding 2 patents that showcase his innovative approach to improving write operations and cache management.

Latest Patents

One of his latest patents is focused on fast write operations. This technique allows a host write request to be written to cache and nonvolatile storage in the data storage device controller, rather than performing an immediate physical write. The controller signals the host that the write operation is complete, while the physical data storage device is updated later. This method enhances performance and ensures data integrity by maintaining two copies of the write operation until the physical update occurs.

Another patent by Howard addresses DASD cache block staging. This method reduces the volume of data transfer between Direct Access Storage Device (DASD) and cache, simplifying the management of variable length records. By always selecting the starting point for staging a record at the beginning of the missing record, this technique efficiently allocates and manages cache space in fixed-length blocks.
