Switching Technology
HIGH-CAPACITY STRATAXGS® ETHERNET SWITCH FAMILY WITH
INTEGRATED 10G SERIAL PHY
Overview
Highlights
• Highest density 10 GbE and
40 GbE switch in the industry.
• Comprehensive DCB features,
including PFC, ECN, and ETS, for
lossless Ethernet.
• Standard TRILL implementation
for multipath switching.
• Integrated Smart Buffer with
self-tuning thresholds ensures
dynamic memory allocation and
optimal performance levels.
• DMVoQ to eliminate head-ofline blocking.
• EEE support for energy savings
• Complete metro features including MPLS, VPLS, and PBB.
• Port virtualization to support
data center virtualized server
implementation.
With the emergence of cloud computing and converged fabrics in data center architectures, datacenter switches must provide other services in
addition to high-density 10 Gigabit Ethernet (GbE)
connectivity and line-rate-per-port performance.
The Broadcom® BCM56840_PLUS family of
switches provides Fibre Channel over Ethernet
(FCoE) and storage virtualization services, allowing
customers to consolidate storage and data traffic
on a single/reliable Ethernet fabric. This consolidation reduces overall power consumption in the
data center, simplifying server I/O and reducing
overall management costs. Additionally, the
BCM56840_PLUS provides Layer 2 multipathing
and data center bridge congestion management
capabilities. These capabilities allow customers to
build scalable, high-performance Layer 2 fabrics,
while network design is simplified by removing
spanning tree and ensuring reliable end-to-end
performance.
Summary of Benefits

and line-card applications.
• Single design meets the needs of multiple markets including Enterprise, HPC, and cloud data
centers as well as carrier-access applications.
