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. Combined with remote
attestation, where a trusted o-box challenger provides an
objective measurement of trust, Measured Boot provides
ongoing binary-level validation during operation.
Modular, Virtualized
Operation System
The 8520 runs Extreme SLX-OS, a fully virtualized Linux-
based operating system that delivers process-level resiliency
and fault isolation. SLX-OS supports advanced switching
features and is highly programmable with support for
REST APIs, Python, and NETCONF/RESTCONF. It is based
on Linux, which oers all the advantages of open source
and access to commonly used Linux tools. With enhanced
support for Trusted Delivery features, such as Measured Boot
and strong security defaults, Extreme SLX-OS continues
to further protect against ever-growing security threats to
infrastructure.
Management
The 8520 can be managed in a variety of ways. REST,
NETCONF management interface or simple on- box
management functions are delivered with CLI for
manual configuration.
Plug-n-Play
Extreme Fabric Automation simplifies and accelerates
the deployment of the data center IP Fabric. The on-box
application runs as a service on the Integrated Application
Hosting environment within the SLX and uses industry-
standard open API based programmable interfaces to
provide the easiest way to deploy, provision and automate
single or multiple data center IP Fabric networks in the
fastest and most ecient way. Extreme Fabric Automation
is also the point of integration for VMware vCenter,
Microsoft Hyper V and OpenStack.
High-Availability and Reliability
The 8520 delivers the high performance and reliability
required by modern enterprises and service provider
data centers. It is designed for high availability from both
a software and hardware perspective, such as a clear
separation between the control plane and data plane and
redundant power supplies and fan modules.
Integrated Application Hosting
The 8520 can run onboard VM-based applications
alongside the switch OS – all without impacting
performance. This flexible and open solution enables
organizations to deploy Extreme-provided or third-
party applications and tools directly on the switch for
security, monitoring, troubleshooting or extended network
functionality—based on customer need— without a separate
hardware device. This unique design does not impact the
control and forwarding plane of the switch and provides
dedicated CPUs, memory and SSD storage for flexible
packet capture and o-line processing.
