Latest Patents

Kihwal Lee holds a patent titled "Method for efficient storage node replacement." This patent describes methods and apparatus for a horizontally scalable high-performance object storage architecture. The architecture allows for complete decoupling of metadata from object storage. Instead of using file names, users receive a locator upon uploading and committing an object. This locator can be stored alongside user-defined metadata or embedded directly in the static content. Clients have the flexibility to choose storage nodes based on dynamic performance measures. The design ensures that performance can scale horizontally by adding more nodes, and it achieves high service availability through object-level synchronous replication, eliminating single points of failure. Additionally, failed nodes can be rebuilt using data copies from other nodes without taking the cluster offline. The ability to add or remove nodes online further reduces maintenance-related service downtime.
