Obsidian announces 40Gbits/s InfiniBand range extenders delivering high-performance disaster tolerance for IBM DB2 pureScale clusters

摘要

As technology partners with IBM in delivering business continuity solutions for high performance synchronously distributed databases, Obsidian has chosen the Information On Demand event to launch its next generation Longbow device, the C400. IBM's pureScale is a clustered DB2 implementation that leverages InfiniBand LAN technology to scale out from small to very large server node counts at a single site while maintaining high transaction rates and fault tolerance. However, until GDPC (Geo-Dispersed PureScale Cluster) DB2 configurations using Obsidian's Longbow technology were released, pureScale was confined to a single location -vulnerable to single-site failures.
