The IS5030 Edge switch provides a high-performing fabric solution in a 1RU form factor by delivering 2.88 Tbps of non-blocking bandwidth with 100 ns port-to-port latency.The IS5030 provides up to 40 Gbps full bidirectional bandwidth per each of the 36 ports. These stand-alone switches are an ideal choice for top-of-rack leaf connectivity or for building small to medium sized clusters. The IS5030 is designed to carry converged LAN and SAN traffic with the combination of assured bandwidth and granular Quality of Service (QoS).

The IS5030 Edge switches are built for high performance, reliability, and manageability. They support redundant and hot-swappable fans and a second power supply can be added for power supply redundancy and hot-swap. They have a built-in PPC405 management module that runs a feature rich embedded chassis management software for hardware health monitoring and diagnostics.

Features and benefits

The Mellanox IS5000 family of Director-class and Edge-class InfiniBand switches have the following features:
  • Converged fabrics
    Inter-processor communication (IPC), application data, or transfers to or from storage easily flow through an IS5000 fabric. Granular QoS and guaranteed bandwidth allocation can be applied per traffic type. This ensures that each type of traffic has the resources needed to ensure the highest application performance.
  • Sustained network performance
    The IS5000 family of switches enables efficient computing by using static routing, adaptive routing, and advanced congestion management. These features ensure the maximum effective fabric bandwidth by eliminating congestion hot spots.
  • World-class design
    The IS5000 family of switches is designed for performance, serviceability, energy savings, and high availability. The IS5030 switches are optimized for industry-standard racks and scale-out computing solutions from industry leaders. For greater scale-out requirements, the IS5200 and IS5600 chassis switches are the ideal choice. Common modules are used across the entire IS5000 Director class of switches, such as leafs, spines, management modules, power supplies, and fans, which provides ultimate value and ease of use.
  • FabricIT: Comprehensive and integrated fabric management solution for cluster computing, database, storage, and grid computing
    FabricIT provides a reliable and scalable management solution for InfiniBand networks that can be deployed as a stand-alone manager on a compute or management node or integrated into the Mellanox IS5000 family of switches. FabricIT includes a comprehensive package for cluster power on, fabric-wide bandwidth and latency verification, and various diagnostic tools to check node-node and node-switch connectivity, provide a cluster topology view, and verify the upper layer protocol.
  • Low-latency switching
    The IS5000 family of switches offer the lowest switching port-to-port latency, providing the most efficient communication between processing nodes, supporting larger and more scalable fabrics, and providing near-linear application performance scaling.
  • Granular QoS for cluster, LAN, and SAN traffic

    IPC, LAN, and SAN traffic can be carried over a common InfiniBand fabric, thereby reducing the number of adapters, switch ports, and cables and lowering space, power, equipment, and operational costs. With support for granular QoS over the IS5000 switches, different traffic types can share the same fabric resources at the appropriate QoS levels, thereby maximizing the utilization of the fabric while maintaining traffic isolation with no compromises to performance.
