Extreme 8520

Next Generation Secure Data Center and

Mobile Edge Leaf Switches

Introducing the Extreme 8520 switches for large scale BGP-EVPN IP

Fabric enterprise data centers and service provider ﬁxed and mobile edge

architectures. As a part of Extreme’s Universal platform, the Extreme 8520

delivers scalable L2 and L3 services and deterministic network performance

while simplifying deployment and reducing cost.

The Extreme 8520 platforms are top-of-rack, ﬁxed form factor

1/10/25/40/100GbE leaf switches with 32MB of packet buer and an overall

non-blocking, in and out throughput of 2Tbps. There are two network

hardware platforms, oering forty-eight 1/10/25 GbE SFP28 ports and either

six or eight 100/40 GbE QSFP28 ports.

As part of Extreme’s Trusted Delivery initiative, the Extreme 8000 Series

of Universal switches introduce powerful security enhancements with a

combination of Secure Boot technology, enhanced by an industry-ﬁrst

Measured Boot implementation. Measured Boot extends the security posture

of the system into the execution of the operating system itself for greater

protection against threats.

The Extreme 8520 network hardware platforms enable organizations to

design open networks that accommodate a variety of applications and east-

west trac patterns. With its high-density scale-out architecture, leading

power eciency, and airﬂow options, the Extreme 8520 platforms deliver

cost-eective solutions that optimizes power, cooling, and data center space,

wherever your center of data might be.

Trusted Delivery Trusted Delivery from Extreme Networks is designed to protect your key service delivery infrastructure at remote, often-unattended sites, as well as within colocation and data center environments where shared facility access is a concern. With Measured Boot – a security mechanism designed to verify the boot and runtime processes – Extreme Networks provides the capability to validate hardware components, boot process, and the operating system from factory to installation.
