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.
