The QLogic 12000 InfiniBand Switch Series of products adapts to a wide range of customer High Performance Computing (HPC) environments. Based on the QLogic TrueScale ASIC platform, these advanced 40Gbps QDR InfiniBand switches offer the highest port count, the highest port density, and the most flexibility for organizations with HPC needs that are continually evolving.

The QLogic 12000 InfiniBand Switch Series of products runs with the QLogic InfiniBand Fabric Suite (IFS).  IFS simplifies InfiniBand networking with automated installation, configuration, and monitoring of the fabric.

  • Unmatched flexibility and scale with 40Gb (QDR) products that scale from 18 to 36 ports
  • Ability to improve HPC cluster efficiency with industry-leading features, including: adaptive routing, dispersive routing, and Virtual Fabrics
  • Designed to meet the most demanding "time-to-solution" needs of the High Performance Computing (HPC) market
  • 40Gb (QDR) InfiniBand Switch offerings from 18 to 36 ports
  • QLogic TrueScale ASIC architecture, with scalable, predictable performance
  • Comprehensive set of advanced InfiniBand features
  • Optional InfiniBand Fabric Suite (IFS) management solution provides expanded fabric views and a powerful set of management tools

High performance computing (HPC) solutions have used InfiniBand networks to meet the needs of the most demanding set of applications. The QLogic 12300 is an 18–36 port, 40Gbps InfiniBand switch designed to cost-effectively link workgroup resources into a cluster or provide an edge switch option for a larger fabric. Customers can manage the modular InfiniBand switch internally or externally. The QLogic 12300 is part of the 12000 Series of products that deliver an unmatched set of high-speed networking features and functions.

Simple Installation and Configuration.
Using the installation and configuration wizards contained in the IFS package allows end users to deploy fabrics in days instead of weeks.

Low Latency.
QLogic's 12300 provides scalable, predictable low latency, even at 90 percent traffic utilization. Predictable latency means HPC applications can easily be scaled without having to worry about diminished cluster performance or costly system tuning efforts.

Flexible Partitioning.
The QLogic 12300 advanced design is based on an architecture that provides a comprehensive set of Virtual Fabric Partitioning capabilities, enabling 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 standard, ensuring the ability to interoperate with all other IBTA-compliant devices.

Highly Reliable.
The highly-reliable 12300 is built around state-of-the-art fault detection and recovery capabilities. It ships with hot-swappable, redundant power and cooling modules.

Easy to Manage.
Customers can manage the 12300 by utilizing an optional embedded fabric management capability and by taking advantage of QLogic's advanced IFS software to facilitate quicker installation and configuration. IFS tools verify fabric configuration, topology, and performance. Faults are automatically isolated to the component level and reported.

Power Optimized.
Maximum performance is delivered with minimal power and cooling requirements as part of QLogic's StarPower™ commitment to developing green solutions for the data center.
