Product Details

The IS5035 switch system provides the highest-performing fabric solution in a 1RU form factor by delivering 2.88Tb/s of non-blocking bandwidth to High-Performance Computing and Enterprise Data Centers, with 100ns port-to-port latency. Built with Mellanox’s 4th generation InfiniScale® IV InfiniBand switch device, the IS5035 provides up to 40Gb/s full bidirectional bandwidth per port. This stand-alone switch is an ideal choice for top-of-rack leaf connectivity or for building small to medium sized clusters. The IS5035 is designed to carry converged LAN and SAN traffic with the combination of assured bandwidth and granular Quality of Service (QoS).

Sustained Network Performance

The IS5035 enables efficient computing with features such as static routing, adaptive routing, and advanced congestion management. These features ensures the maximum effective fabric bandwidth by eliminating congestion hot spots. Whether used for parallel computation or as a converged fabric, the IS5000 family of switches provides the industry’s best traffic-carrying capacity.

World-Class Design

The IS5035 is an elegant top of the rack design, that is designed for performance, serviceability, energy savings and high-availability. The design is optimized for fitting into industry standard racks and also for scale-out computing solutions from industry leaders. The IS5035 supports reversible airflow making the design fit into data centers with different thermal designs. Redundant and hot swappable power supplies and fans provide high availability for both High-Performance Computing and Enterprise Data Center applications. Status LEDs for fans and power supply units are placed on both sides of the system for easy status identification. Quick start guide, rack mount kit, AC power cord and RJ45 to DB9 console cables are provided as part of the standard system providing new levels of out of the box experience and performance.

FabricIT™ - The Fabric Manager

FabricIT™ delivers complete fabric management and chassis management. FabricIT fabric management running on the IS5035 enables fast setup for cluster bring-up, fabric-wide bandwidth & latency verification, and various diagnostic tools to check node-node, node-switch connectivity and cluster topology view. FabricIT chassis management is embedded in IS5035 and provides administrattive tools to manage the firmware, power supplies, fans, ports, and other interfaces. Various threshold parameters can be set and the chassis can be managed inband and outband.
