Meets Today's Application
Demands with High Performance
and Low Latency
As data centers virtualize more of their
servers and VM density per server
increases, organizations will require
higher bandwidth connectivity to support
the explosion of data and application
processing. With 1/10 GbE and
40 GbE options, Brocade VDX 6940
Switches deliver the high-performance
computing needed to keep up with
the demands of a virtualized data
center, allowing organizations to reduce
network congestion, improve application
performance, and meet the capacity
required by 10 GbE servers. The 40 GbE
VDX
VDX VDX VDX
and 100 GbE uplinks can easily aggregate
high-bandwidth traffic and reduce
bottlenecks that occur when aggregating
multiple 10 GbE or 40 GbE connections,
keeping data center networks working at
peak performance.
In a Brocade VCS fabric, Brocade VDX
6940 Switches also help maximize
network utilization with hardware-based
Brocade ISL Trunking. Organizations
can create a 120 GbE Brocade ISL
trunk by utilizing three 40 GbE ports
or 12 10 GbE ports between Brocade
VDX 6940 Switches. The Brocade ISL
trunk is automatically formed between
two Brocade VDX switches when they
are linked together, allowing traffic to be
equally distributed among all ports. This
increases link efficiency and limits traffic
disruptions, especially during high-traffic
times. Also, 40 GbE and 10 GbE trunking
is supported between Brocade VDX

Brocade VDX 6940 Switches offer a
unique balance between two conflicting
attributes—buffer and latency. Niche
products with very high buffer often suffer
from high latency, and products with
ultra-low latency are not a good fit for
data centers with bursty traffic. Brocade
VDX 6940 Switches, with a purpose-built
data center chip, excel in optimizing buffer
and latency to deliver better application
performance. These switches deliver
800 ns any-port-to-any-port latency. In
addition, they offer an industry-leading
24 MB deep buffer. This provides the
buffering capacity to handle increases in
traffic, especially during peak times when
ports are congested, allowing traffic to be
distributed across the ports. Brocade VDX
6940 Switches also feature a single ASIC
