Building Clusters with HyperScale™
Voltaire’s fourth generation Grid Director 4000 series of smart switches addresses the growing size and complexity of clusters with 40 Gb/s connectivity, advanced carrier-class management and a unique HyperScale™ stackable architecture. The Voltaire QDR InfiniBand Grid Director 4700 is a director-class switch that features 324 ports of 40 Gb/s InfiniBand connectivity in a 19U chassis and between 100 and 300 nanoseconds of port-to-port latency.
The switch’s HyperScale architecture provides a unique inter-switch link capability for stacking multiples of 324 ports to form highly scalable, cost effective, and low latency fabrics. As a result, I/O bottlenecks common with multi-core servers are removed, allowing applications to operate at maximum efficiency.
With configurations of up to 324 ports or double-sided 648 ports of 40 Gb/s per port InfiniBand connectivity, the Voltaire QDR InfiniBand Grid Director 4700 delivers an impressive 51.8 Tbps of non-blocking bandwidth and the lowest latency in the industry. Its smart design provides unprecedented levels of performance and makes it easy to build clusters that can scale out to thousands of nodes.
Smart Switches for Next Generation Data Centers
The Voltaire QDR InfiniBand Grid Director 4700 comes with many new smart capabilities to meet the needs of next generation data centers.
- As clusters continue to grow, Voltaire offers higher port densities enabled with new optical, pluggable (QSFP) interfaces.
- Leveraging advances in cabling technology together with the switch’s advanced port and signal optimization capabilities, the QDR InfiniBandGrid Director 4700 can determine the optimal settings for the connected QSFP cable. This makes the selection of cables more flexible and provides for simpler and faster cluster deployments.
- The switch’s on-board device management provides a simple interface for deploying, troubleshooting, maintaining and upgrading the switch.
- The QDR InfiniBand Grid Director 4700 works with Voltaire’s Unified Fabric Manager (UFM), which automatically discovers, virtualizes, monitors and optimizes the fabric infrastructure and accelerates the active applications.
- Voltaire fabric optimization includes advanced congestion management capabilities for detecting congestion with advanced multi-path and adaptive routing capabilities to prevent degraded application performance.
Building Efficient Clusters & Grids
The Grid Director 4700 is the industry’s most cost-effective building block for deploying high performance clusters and data centers. Whether looking at price-to-performance or energy-to-performance, the QDR InfiniBand Grid Director 4700 reaches new levels of achievement.
Voltaire’s InfiniBand solutions have been at the top of both the Top500 list of fastest supercomputers in the world and the Green500 (green500.org) list of “greenest” supercomputers for years, indicating recognized leadership in both performance and efficiency. The design of the Grid Director 4700 ensures that this leadership will be maintained in the QDR era.
Also available is the Voltaire Grid Director™ 4036, which offers 36 QDR InfiniBand ports in a 1U switch.
