The Cisco® SFS 7000D InfiniBand Server Switch sets the standard for cost-effective, low-latency, 4X DDR and SDR InfiniBand switching for building high-performance clusters.
High-performance computing (HPC) applications that solve complex, computationally intensive problems are widely deployed within academic and research communities and enterprises because they deliver significant business benefits. An important enabler for the broad adoption of HPC applications is the practice of clustering multiple industry-standard servers using a high-speed network to provide supercomputer performance, at a fraction of the cost of traditional supercomputers.
The Cisco SFS 7000D delivers an ideal combination of price, performance, and packaging for building high-performance server clusters of all sizes. The Cisco SFS 7000D (Figure 1) provides 24 InfiniBand 4X ports that can operate in double data rate (DDR) or single data rate (SDR) mode, which delivers 20- or 10-Gbps server connectivity respectively. The Cisco SFS 7000D is a fully nonblocking, 960-Gbps cross-sectional bandwidth switch fabric that has less than 200 nanoseconds (ns) of port-to-port latency. In common with the Cisco SFS 7000P, the Cisco SFS 7000D comes with the embedded Cisco InfiniBand Subnet Manager, which is capable of running large clusters in a single, compact 1 rack unit (1RU) chassis.

The Cisco SFS 7000D provides the following customer benefits:
• Powered ports to enable flexible copper and optical interface configurations
FABRIC DENSITY AND SCALABILITY
The Cisco SFS 7000D is a fixed-configuration, 24-port, DDR/SDR 20- or 10-Gbps 4X nonblocking InfiniBand switch that is ideally suited to "top-of-rack" switch configurations that, when combined with other Cisco SFS 7000 Series InfiniBand switches, provide access-switch functionality in very large HPC clusters consisting of thousands of nodes to support the most demanding HPC applications.
The Cisco SFS 7000D is designed for enterprise-class reliability that supports hot-swappable redundant power supplies and cooling. The embedded Cisco InfiniBand Subnet Manager constantly synchronizes operational information with other Cisco InfiniBand Subnet Managers within the network so that if any one switch fails, another subnet manager can assume active subnet manager responsibility. The Cisco InfiniBand Subnet Manager also provides rapid rerouting in the event of a path failure or switch failure, maintaining maximum availability on the InfiniBand network.
Using the embedded Cisco InfiniBand Subnet Manager and systems management, the Cisco SFS 7000D can be deployed in a ready-to-use fashion in the network within minutes. Configuration and maintenance are simplified with a full-featured GUI and CLI using serial console, Telnet, or Secure Shell (SSH) Protocol Version 2, enabling remote management, monitoring, diagnostics, and updates. The Cisco SFS 7000D can be managed using the Cisco SFS management suite or with existing network management systems using standard protocols such as Simple Network Management Protocol (SNMP), with supported SNMPv3 security.
The Cisco SFS 7000D supports a full complement of performance monitoring, including graphing bandwidth utilization and error rates in real time to give system administrators an unprecedented view of fabric performance. The Cisco SFS 7000D quickly identifies and isolates trouble areas or "hot spots" using comprehensive fabric and chassis management embedded within the switch that automatically detects, isolates, and recovers from component-level failures. Each FRU supports a full suite of system-level diagnostic health checks that assess the health of all components to detect potential problems, such as rising temperature or internal error rates, and report these anomalies in real time to proactively notify the system administrator.
The embedded Cisco InfiniBand Subnet Manager can manage InfiniBand switch networks consisting of thousands of nodes. It may also be combined with the standalone, high-performance Cisco InfiniBand Subnet Manager to scale to much larger clusters.
The Cisco SFS 7000D single-chip design offers fully nonblocking, DDR (20-Gbps) and SDR (10-Gbps) full duplex performance at an optimal price per port compared to other networking technologies. It supports autosensing of DDR or SDR attached devices and also supports the capability to forward packets between DDR and SDR connections to provide better utilization of system resources and investment protection for existing InfiniBand 4X devices. For example, the Cisco SFS 7000D can support 16 SDR server connections with 8 DDR uplinks to the InfiniBand fabric core, which provides nonblocking uplink capacity and high-density server connectivity.
The Cisco SFS 7000D also supports sophisticated embedded system and network management that simplify network management, monitoring, diagnostics, and maintenance. It is fully compliant with the IBTA 1.0a and 1.1 standards, and is interoperable with other IBTA standards-compliant InfiniBand products. The embedded Cisco InfiniBand Subnet Manager can manage InfiniBand switch networks consisting of thousands of nodes. Optionally, the standalone, high-performance Cisco InfiniBand Subnet Manager enables the Cisco SFS 7000D to scale to support the largest InfiniBand switch networks. The Cisco SFS 7000D (Figure 2), when combined with the Cisco SFS 3000 Ethernet and Fiber Channel gateways, provides transparent IP and storage connectivity between high-performance InfiniBand server clusters and Cisco Catalyst
® 6000 Series Switch-based LANs and Cisco MDS 9000 Family switch-based SANs.
