Popis: In 2007 we introduced jSCSI 1.0 to the public. The use case was to access block-patterns directly from Java without any third party JNI invoked software. In the last 2 years we explored the capabilities to assimilate multithreading in jSCSI. The goal was to leverage the outstanding features of the new Java multithreading extension introduced with Java5/Java6 and incorporate them into our proven block-level accessing framework. Today, we present the next incarnation of jSCSI 1.0, jSCSI 2.0 which yields significant performance improvements by utilizing Java s advanced multithreading capabilities. We show that our Java based implementation of a low-level architecture is not only a proposing alternative in terms of performance but also in the ease-of-use compared to common JNI-invoked system calls. Therefore, we argue that jSCSI 2.0 is not only a platform independent implementation of the iSCSI protocol, but also a fast and robust proof for implementing low-level applications in Java. ; published

Abstrakt:In 2007 we introduced jSCSI 1.0 to the public. The use case was to access block-patterns directly from Java without any third party JNI invoked software.

The goal was to leverage the outstanding features of the new Java multithreading extension introduced with Java5/Java6 and incorporate them into our proven block-level accessing framework. Today, we present the next incarnation of jSCSI 1.0, jSCSI 2.0 which yields significant performance improvements by utilizing Java s advanced multithreading capabilities. We show that our Java based implementation of a low-level architecture is not only a proposing alternative in terms of performance but also in the ease-of-use compared to common JNI-invoked system calls.
