InfiniBand is an industry-standard high-performance interconnect for clusters and enterprise grids. This industry-standard fabric creates clusters that address many of the requirements, such as those found in scientific, technical, and financial applications. InfiniBand solutions are designed for high availability and can also deliver the scalability required by distributed database processing.

The QLogic 12200-BS21 is a 36-port, 40 Gbps InfiniBand switch that cost-effectively links workgroup resources into a cluster. This compact 1U solution is used for building small node count fabrics. Included in the switch are redundant power supplies, power cords, a rack mount kit, and the QLogic InfiniBand Fabric Suite. The QLogic 12800-040 is a 72-port, 40 Gbps InfiniBand switch that links resources using a scalable, low-latency fabric. The 12800-040 supports up to four 18-port QDR leaf modules. Included in the switch are redundant QDR Management Modules, redundant power supplies, redundant fans, power cords, a rack mount kit, and the QLogic InfiniBand Fabric Suite. The QLogic 12800-180 is a 324-port 40 Gbps InfiniBand switch designed to maintain larger clusters, supporting up to eighteen 18-port QDR leaf modules. Included in the 12800-180 are redundant QDR Management Modules, a full complement of Management Modules to provide a 100% nonblocking fabric for all ports, redundant power supplies, redundant fans, power cords, rack mount kit, and QLogic InfiniBand Fabric Suite.

These new QDR high-performance server switches enable you to form high-performance clusters and grids that deliver the performance required for you to realize the full potential of your applications and systems.

** The IBM 7874-036 and IBM 7874-072 can be mounted in any IBM 19-inch rack. To address the need for larger system cable management of the InfiniBand cables, the IBM 7874-324 is required to be installed in a 7014-T42 rack, with the rack extender feature number. The rack extender is 20-inches deep.

Note: Larger configurations require the use of an external Host Subnet Manager (HSM). This will be running on an IBM System x3550 or IBM System x3650, with InfiniBand Host Channel Adapter and InfiniBand cable. Commercial configurations can use the Embedded Subnet Manager (ESM), which is monitored from the network. More than 144 nodes will require the use of the HSM.

Benefits

The QLogic 12800 and 12200 InfiniBand switches offer the following benefits:
  • Low latency: The QLogic 12800 and 12200 provide scalable, predictable low latency, even at 90% traffic use. Predictable latency means that HPC applications can be scaled easily without worrying about diminished cluster performance or costly system-tuning efforts.
  • Flexible partitioning: The QLogic 12800 and 12200 advanced design are 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.
  • Modular design: InfiniBand port, power, cooling, and management modules are common in the series, giving customers the flexibility to deploy and grow HPC environments in a cost-effective fashion.
  • Investment protection: The QLogic 12800 and 12200 adheres to the InfiniBand Trade Association Version 1.2 specification, ensuring the ability to interoperate with all other IBTA-compliant devices.
  • Highly reliable: This system is designed for high availability with features that include port-to-port and module-to-module failover, non-disruptive firmware upgrades, component-level diagnostics and alarming, and both in-band and out-of-band management.
  • Easy to manage: The 12800 and 12200 use QLogic’s advanced IFS software for 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.
  • Simple installation and configuration: Using the installation and configuration wizards contained in the IFS package allows users to bring up fabrics in days instead of weeks.
  • 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.
