ExtremeRouting™ SLX 9850
Next-Generation Modular Routing Platform for the Digital Era
With mobile connectivity, cloud services, and 4K HD video streaming
for billions of devices the norm, and the Internet-of-Things (IoT) and
augmented reality and virtual reality on the horizon, organizations must
modernize the way they communicate and conduct business. In addition
to consuming an enormous amount of network capacity, these services
increase operational complexity just as organizations are striving to meet
customer demands for greater business agility and performance.
To succeed in the digital era, organizations need network platforms that
allow them to simplify and speed up operations, without increasing
costs. Such platforms incorporate innovative software to analyze and
automate network operations, thereby reducing OpEx, and provide flexible
deployment options with forwarding performance and scale to dramatically
Extensible Routing Platform
The ExtremeRouting SLX 9850 is designed to cost-effectively deliver the
density, scale, and performance needed to address the explosive growth in
network bandwidth, devices, and services—today and well into the future.
This flexible platform, powered by Extreme SLX-OS, provides carrier-class
advanced features that leverage proven Extreme routing technology
currently deployed in the most demanding data center, service provider,
and enterprise networks. And it is all delivered through best-in-class
forwarding hardware. The extensible architecture is designed for investment
protection, to readily support future requirements for greater bandwidth,
High Availability with
230 Tbps-scale Forwarding
The SLX 9850 is the industry’s most powerful IPv4, IPv6,
MPLS/Multi-VRF and BGP-EVPN data center router,
providing a cost-efficient solution that is purpose-built
for the most demanding service provider and enterprise
data center applications. The robust system architecture,
versatile feature set, and high level of flexibility enable it to
scale from the data center spine to the data center core.
Designed with state-of-the-art network processing
technology, the SLX 9850 has a non-blocking switching
capacity of up to 230 Tbps. An advanced distributed
hardware architecture with fine-grained QoS support
enables full-duplex, high-speed performance for any
mix of IPv4, IPv6, MPLS and BGP-EVPN VXLAN Overlay
services. This innovative system architecture offers several
- Clos-based distributed non-blocking architecture:
Provides the foundation for a robust, scalable data
- Midplane-free design: Allows interface modules to
communicate directly with switch fabric modules,
enabling the chassis to have an efficient front-to-back
airflow design and no signal integrity degradation.
- High-availability implementation: Provides a clear
separation between the control plane and data plane at
10 Gigabit Ethernet (GbE) speed to enable operational
performance at high loads.
- Distributed network processing, ultra-deep packet
buffers, and advanced QoS capabilities across the
system: Streamlines execution of a rich feature set at
high data rates, even for bursty or long-lived traffic flows.
- Complete redundancy: Features a fully redundant
architecture with redundant power supply modules,
management modules, fan modules, and switch fabric
modules to minimize single points of failure.
- The SLX 9850 is available in two different models: the
SLX 9850-4, a four interface-slot system, and the SLX
9850-8, an eight interface-slot system. Management
modules, interface modules, and power supply modules
are interchangeable across both the four- and eight-slot
models, thereby decreasing inventory and maintenance
costs. All modules are hot-pluggable, minimizing system
disruption when adding or replacing a module.
