Lenovo QLogic 12200 and 12300 InfiniBand Edge Switches

QLogic 12200 and 12300 InfiniBand Edge Switches for the IBM Intelligent

Cluster and IBM iDataPlex

Product Guide (withdrawn product)
Over the past 10 years, InfiniBand networks have become the preferred means for interconnecting high performance computing (HPC) resources. The QLogic 12200 and 12300 are 36-port Quad Data Rate
(QDR, 40 Gbps) InfiniBand switches designed to cost-effectively link workgroup resources into a cluster or provide an edge switch option for a larger fabric. The 12200 is a fixed configuration, externally managed InfiniBand switch; the 12300 is a modular, internally or externally managed InfiniBand switch.
Both switches are part of the 12000 Series of products that delivers an unmatched set of high speed networking features and functions.
Figure 1 shows the rear of the 12200 switch. The 12300 is very similar in port layout.

The QLogic 12200 and 12300 QDR InfiniBand edge switches are based on QLogic TrueScale ASIC technology and deliver the next evolution in switching for high performance computing (HPC). The available models are tailored for the requirements of the solution:

• The QLogic 12200 Fixed Configuration switch for the IBM Intelligent Cluster (0449-019 and 0449-028) provides 36 QDR ports in a compact 1U 14.5-inch deep fixed form factor, making it the ideal edge switch for large HPC fabric deployments. Model 0449-028 has two power supplies for redundancy and supports the optional management module, part number 68Y6995.
• The QLogic 12200 Fixed Configuration switch for iDataPlex (0449-020 and 0449-029) provides 36 QDR ports in a compact 1U 14.5-inch deep fixed form factor. It includes AC power entry, air flow, and mounting hardware tailored for IBM iDataPlex, making it the ideal embedded or edge switch for iDataPlex solutions deploying InfiniBand. Model 0449-029 has two power supplies for redundancy and supports the optional management module, part number 68Y6995.
• The QLogic 12300 Configurable switch for IBM Intelligent Cluster (0449-021) is an ideal edge switch for enterprise clustering. It provides 36 QDR ports in a standard 1U 26-inch deep form factor and includes a management processor supporting chassis management and an embedded InfiniBand Subnet Manager. The highly available 12300 design is built around state-of-the-art fault detection and recovery capabilities. It ships with redundant hot-swap power and cooling modules.

Benefits
The QLogic 12200 and 12300 InfiniBand switches offer the following benefits:

• Low latency: The QLogic 12200 and 12300 provide scalable, predictable low latency, even at 90%traffic use. Predictable latency means HPC applications can be scaled easily without worrying about diminished cluster performance or costly system tuning efforts.
• Flexible partitioning: The QLogic 12200 and 12300 advanced design is based on an architecture that provides comprehensive virtual fabric partitioning capabilities that enable the InfiniBand fabric to support the evolving requirements of an organization. The TrueScale architecture, together with IFS, allows the fabric to be shared by mission-critical applications while delivering maximum bandwidth utilization.
• Investment protection: The 12000 series of switch products adhere to the IBTA version 1.2 specification, ensuring the ability to interoperate with all other IBTA compliant devices.
• Highly reliable: The highly available 12200 and 12300 design is built around state of the art fault detection and recovery capabilities. In addition, 12300 ships with hot swappable, redundant power and cooling modules.
• Easy to manage: The 12200 takes advantage of QLogic’s advanced InfinBand Fabric Suite Software to facilitate quicker installation and configuration. IFS has advanced tools to verify fabric configuration, topology and performance. Faults are automatically isolated to the component level and reported. In addition, an optional embedded capability of 12300 can be used for switch management.
• Power optimized: Maximum performance is delivered with minimal power and cooling requirements as part of QLogic’s Star Power commitment to developing green solutions for the data center.

QLogic InfiniBand Fabric Suite 6.0
InfiniBand Fabric Suite 6.0 is a new fabric management software product that enables high fabric performance. It incorporates Virtual Fabrics configurations with application-specific Class-of-Service (CoS), Adaptive Routing and Dispersive Routing, performance-enhanced versions of vendor- specific MPI libraries, and support for torus and mesh network topologies.
Features of IFS 6.0 include:

• QLogic Virtual Fabrics – lets you set a Class-of-Service level for each application running on the fabric to ensure the appropriate bandwidth
• QLogic Adaptive Routing – monitors the fabric and ensures that traffic is routed down the most efficient path thereby eliminating bottlenecks
• QLogic Dispersive Routing – balances the traffic load on the fabric using QLogic Performance Scaled Messaging (PSM) to ensure high performance
• MPI Library Support – supports the widely used Message Passing Interface (MPI) libraries to ensure efficient utilization
• Advanced Topology Support – enables the use of Torus and Mesh topologies for application environments
