Abstract
We propose JAS, a JVM-based active storage framework for object-based storage systems. JAS programs the active storage functions of users as Java codes, and allows them to be executed on different OSD platforms (Operating systems and hardware) without recompiling. JAS offloads the active storage code from a client to the OSD by extending the standard OSD command set, and execute the Java code on the OSD ondemand by triggering them through extended client interfaces. We have implemented JAS under an object-based storage system. Experimental results show that the JVM-based active storage framework has been successfully set up, and this cross-platform design can largely improve system performance.
