ADS - a handle-based storage architecture under grid computing

The paper proposes a new networked storage architecture and interface by using the handle system (HS). We call it autonomous data system (ADS). This leads to a clean and simple interface for networked storage and data management. ADS can be operated independently from computers and applications. As today's network and computing become increasingly complicated, data management is critical for the efficient use of information. The proposed architecture addresses these issues by having a different demarcation and layering from conventional SAN (storage area network) (block level) and NAS (network attached storage) (file level). In other words, ADS defines an application level demarcation and is better for scalability, interoperability, efficiency, QoS support and manageability. We also propose an adaptation layer to support legacy applications for compatibility. Lastly we compare ADS with OSD (object-based storage device). ADS is to complete the process of a logical separation of storage from a computer and its OS and file systems.
