Latest Patents

One of his latest patents is titled "Method for selectively enabling and disabling read caching in a storage subsystem." This invention introduces a mechanism for selectively disabling and enabling read caching based on the past performance of the cache and current read/write requests. The system enhances overall performance by utilizing an autonomic algorithm to disable read caching for regions of backend disk storage that have historically low cache hit ratios. Consequently, more cache becomes available for workloads with larger hit ratios, reducing the time and machine cycles spent searching the cache for data that is unlikely to be present.

Another notable patent is the "Thin-provisioning adviser for storage devices." This invention provides a method, apparatus, and computer program product for thin-provisioning of storage in a storage system by an adviser. It creates a workload profile of the storage from performance data, which includes a measurement of changed data per a predetermined time and resource utilization data over a period. The invention derives a capacity estimate from the measurement of changed data and a placement estimate from the resource utilization data. It recommends a target capacity and placement location to users based on these estimates, along with a predicted resource utilization.
