Next-Generation 100G Spine Switch Enables Digital Transformation

This fixed spine switch delivers the high-density 100G / 40G connectivity required by enterprise and cloud data centers. Its programmable architecture is designed for dense workloads, with the capacity to transition to emerging protocols and new technologies. Automation, simplified management, and in-context end-to-end network visibility help infrastructure teams continue to drive SLAs as they transition.

Adaptable Architecture

  • Programmable ASIC enables adoption of new protocols and technologies without disrupting network operations
  • High-density 100G server connectivity in a 1U fixed form factor switch with a 24MB dynamically shared packet buffer for high-performance workloads
  • 2 Tbps/1.3Bpps switching capacity for high density and scale for growth
  • Payload timestamping to more accurately set and measure performance SLAs

Embedded Network Visibility

  • Scale services across the network for seamless support of highly distributed multi-tier application workloads
  • Rich network parameter filters (IP and MAC addresses, port numbers, VNIs) and workload matching identify workload-specific actions and mitigate risk
  • Automated application of rule-based actions (count, drop, mirror) to incoming network traffic, with further actions outside the switch including pushing context-rich data to Extreme SLX Insight Architecture or Extreme Workflow Composer and to third-party applications
  • Provides flexible, high-performance data streaming for additional off-device processing, reporting, and archiving, and features industry-leading 128GB of dedicated storage for analytics

Adaptable Architecture

Address today’s data center virtualization and workload density demands with a flexible architecture that delivers cost-effective density, scale, and performance, and a programmable ASIC that can adapt to protocol and technology innovations through an OS upgrade.

Embedded Network Visibility

Gain insights that drive faster troubleshooting with embedded visibility from the physical network to the application workload provided by Extreme SLX Insight Architecture and SLX Visibility Services, powered by the SLX-OS.

DevOps Inspired Automation

The SLX 9240 and Extreme Workflow Composer™ enable cross-domain automation throughout the network management lifecycle. Our turnkey, customizable approach minimizes execution delays and assures easy integration with cross-domain workflows for efficiency and risk reduction.
