Product Brief
Overview
Marvell® Prestera® 98DX35xx series are small footprint,
low-power, highly-integrated, feature-rich stackable 24 and 48
ports intelligent multilayer Ethernet switches, purpose-built to
address the specic requirements of the borderless enterprise
access, as mobility and cloud applications extend the traditional
boundaries.
The digital transformation and emerging technology landscape
– remote access, cloud-native models, proliferation of IoT
devices, articial intelligence (AI) applications, WiFi6,
cybersecurity threats, media-rich applications, smart edge
services – drive new requirements in network access and edge,
elevating network intelligence, performance, visibility and
security.
Digital disruption is creating a pressing need for faster speeds
and more access connectivity options in the enterprise.
Media-rich applications and WiFi6 increasing bandwidth
requirements are placing tremendous pressure on the access
network. 98DX35xx multigigabit speeds on all downlink ports is
transformative to capitalize on Wi-Fi 6 and 802.11ac Wave 2
wireless performance with the existing Ethernet access cabling,
while delivering management simplicity. 10G and 25G uplinks
provide backwards compatibility with legacy equipment while
enabling migration to higher network capacity reective of the
access bandwidth growth.
98DX35xx is an integral part of the unied Prestera Ethernet
switch and Alaska PHY Enterprise solution set, architected from
the ground up to accelerate digital transformation on the
network edge. TrackIQ, NetIQ and SecureIQ groundbreaking
technologies lay out the essential foundation for innovations in
network visibility, intelligence and security.
SecureIQ multilayer zero-access trust security secure boot and
storage, programmable sensors, and line-rate 256b MACSec
encryption on all ports deliver network-embedded
trustworthiness, enable encrypted trafc analytics applications
and provide protection to the hardware and network software
from ever-evolving security threats.
TrackIQ precise application-aware telemetry collection at
line-rate and predictive health reporting enable actionable
analytics applications and expedite forensic troubleshooting.
A variety of data export and streaming options provides a 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.
Marvell Prestera Control and Management Subsystem
advanced interfaces, and integrated Arm Cortex CPU cores
eliminate external components, providing signicant savings to
platform Bill Of Materials (BOM). The embedded multi-core CPU
provides services ofoad and direct access to the switch
pipeline, allowing applications to take full advantage of
hardware features.
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 98DX35xx family of Ethernet switches, designed to operate
in xed and modular chassis platforms, are ideal for Enterprise
Access and Edge deployments.
A Family of 1/2.5/5/10/25/40/50/100G Ethernet Switches for Enterprise Access and Edge
