Product Brief
Overview
Marvell® Prestera® 98EX56xx series deliver scalable feature-rich
high-capacity Ethernet switches designed to address the
emerging needs of borderless Enterprise. Marvell
groundbreaking technologies lay out the essential foundation
for innovations in network visibility, intelligence, performance
and security in modern campus networks, while delivering
higher bandwidth required for network resiliency and in order
to accommodate for the latest LAN and Wi-Fi6 access points
technologies capacities.
The switches integrate high performance 28G and 56G I/O
technology, supporting up to 400GbE ports on the larger
devices. These high-performance links provide the capacity for
the North-South network trafc driven by the Hybrid Cloud and
Co-location deployment trends of cloud services for traditional
enterprise networks.
Supporting the traditional 24 and 48 port interfaces at either
25/50/100GbE these devices allow for aggregation of the
access switches for various size campus deployments. Mixing
these downlink speeds with 2 to 8 uplink ports at
100/200/400G provide the substantial capacity increase
corresponding to the speed upgrades driven in the access by
the WiFi6 standards, multigigabit wired equipment and general
growth in workloads bandwidth.
The Marvell® Prestera® 98EX56xx series also enables advanced
high port radix system designs either in modular form factor or
via port breakout modes enabling each individual 100G QSFP28
interface to support 4 individual ports at independent speeds.
This high radix connectivity option scales to up to 1024 ports
enabling a collapse of the aggregation and core layers or the
access and aggregation layers reducing the network from 3 to 2
layers.
98EX56xx is an integral part of the unied Prestera® Ethernet
switch and Alaska® PHY Enterprise solution set, architected
from the ground up to accelerate the digital transformation.
TrackIQ, NetIQ and SecureIQ groundbreaking technologies lay
out the essential foundation for innovations in network
visibility, intelligence and security.
SecureIQ multilayer security programmable security sensors,
security-groups segmentation and optionally integrated
line-rate 256b MACSec encryption, deliver network-embedded
protection, essential for making the network access more
secured and resilient against ever-evolving security threats.
TrackIQ precise application-aware telemetry collection at
line-rate and predictive health reporting enable actionable
analytics applications and expedites forensic troubleshooting.
Variety of data export and streaming options provides high
degree of integration with analytics tools exibility.
NetIQ programmable engines, embedded compute and robust
workload management enable smart services ofoad,
accelerate intelligent data processing at or near the network
access edge, reducing hybrid cloud bandwidth requirements,
and empower AI-driven autonomous networking.
SyncE and high accuracy one-step and two-step PTP further
usher network deployments that require precise time
synchronization.
The unied software development kit (SDK) industry-standard
switch abstraction interfaces enable networking system
vendors to easily migrate across networking silicon choices,
reduce development costs and accelerate time to market.
The 98EX56xx family of Ethernet switches, designed to operate
in xed and modular chassis platforms, are ideal for Enterprise
Aggregation and Core deployments.
A Family of 10/25/40/50/100/200/400G Ethernet Switches for Enterprise Aggregation
