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 InfiniBand Fabric Suite Software to facilitate quick 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.
