The QLogic 12800-180 and 12800-360 QDR InfiniBand director switches, based on QLogic TrueScale ASIC technology, deliver the next evolution in switch fabric performance for High Performance Computing (HPC) environments.
These switches deliver high port density and low power per port:

• The 12800-180 provides 324 QDR ports using 18-port Ultra-High Performance (UHP) leaf modules or 432 QDR/DDR ports using 24-port Ultra-High Density (UHD) leaf modules in a 14U chassis.
• The 12800-360 provides 648 QDR ports using 18-port Ultra-High Performance (UHP) leaf modules or 864 QDR/DDR ports using 24-port Ultra-High Density (UHD) leaf modules in a 29U chassis.

The high-availability 12800 design includes hot swappable InfiniBand spine and leaf modules, fully redundant power and cooling, and redundant management processors supporting chassis management (CLI and GUI), as well as embedded InfiniBand Subnet Managers (SMs). The 12800 also supports advanced QLogic fabric features including adaptive routing, Virtual Fabrics (vFabric), Quality of Service (QoS), and management wizards for automated installation, configuration, and monitoring to maximize operational efficiency

Benefits

The QLogic 12800 InfiniBand switch offers the following benefits:

• Low Latency: The QLogic 12800 provides 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 12800 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.
• 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 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 uses 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 end 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.
