The grid block device: Performance in LAN and WAN environments

Abstract

We present initial results from the implementation of the Grid Block Device, a distributed, replicated block device for the Grid based on the the replication algorithm of Y. Amir[1]. It supports application-specific replication strategies and consistency models. Although the presented WAN results are dissapointing because of issues with the underlying group communication library, we believe the LAN results show that the Grid Block Device could become a viable solution for truly distributed storage. © Springer-Verlag Berlin Heidelberg 2005.
