Obsidian Announces 40Gbits/s InfiniBand Range Extenders Delivering High-Performance Disaster Tolerance for IBM DB2 pureScale Clusters
Longbow C400 enables QDR stretched clusters over WDM networks
Las Vegas, NV – October 18, 2012 – 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. Longbows transparently extend the cluster's InfiniBand fabric over tens of miles, allowing a single InfiniBand cluster to be physically dispersed across remote sites - while still functioning as a synchronous, active:active mirror. In normal operation both sites are concurrently active, relying on Longbow connectivity to maintain storage and metadata coherence. In the event of a site failure, traffic automatically fails over to the surviving site, and fails back when services are restored.
Obsidian's 100-series Longbow products are based on 10Gbits/s WAN interfaces, running at 4X Single Data Rate (SDR) InfiniBand LAN speeds. At IOD, Obsidian is launching the Longbow C400, which operates at 4X Quad Data Rate (QDR) InfiniBand speeds over up to four aggregated 10Gbits/s WAN channels using Wavelength Division Multiplex (WDM) technology across a single fiber pair.
“While building on the heritage of our first-generation Longbow C100s with four times the throughput in the same physical and power footprint, the C400s go further to offer advanced features such as the graceful tolerance of WAN channel loss, Forward Error Correction (FEC) options and even lower latencies”, remarked Obsidian's CVO, Dr. David Southwell, “By leveraging any regional/metro area WAN link supporting one, two or four 10G wavelengths, Obsidian has bridged high-performance 40G LANs with pervasive and cost-effective 10G WAN infrastructure in a fault tolerant way. This translates directly to higher GDPC transaction rates for DB2 pureScale users, intrinsically robust WAN connectivity and a simplification of the management of the optical WAN circuits.”
Meet the Obsidian team at the IOD event (Mandalay Bay, Las Vegas) in booth #325 from October 21st to October 24th.
About Obsidian Strategics
Obsidian Strategics™ is the developer of Longbow™, a series of InfiniBand products featuring range extension, routing and encryption. Longbow technology allows an InfiniBand fabric, normally a short-range network used in high-performance computing, to be extended via optical fiber over varying distances. Longbow connects across Campus, Metro or Global networks to enable unparalleled real-time backup over long-distance, high-bandwidth video transmission and efficient movement of large data sets to compute and storage resources. www.obsidianstrategics.com.
