BROCADE VDX 6740T-1G SWITCH
The Brocade VDX 6740T-1G (Figure 3) offers
48 1000BASE-T ports and two 40 GbE
QSFP+ ports. Each 40 GbE port can be
broken out into four independent 10 GbE
SFP+ ports, providing an additional eight
10 GbE SFP+ ports for uplink. All 48
1000BASE-T ports can be upgraded to
48 10GBASE-T ports via a Capacity on
Demand (CoD) software license. Two
40 GbE ports are enabled as part of the
base license. The additional two 40 GbE
ports can be upgraded via the Ports on
Demand (PoD) software license.

The Brocade VDX 6740, 6740T, and
6740T-1G are all Ethernet fabric Top-of-Rack
(ToR) switches that support a demanding
data center environment. Access ports are
positioned to allow for easy server
connectivity and to simplify cabling. With
a choice of front-to-back or back-to-front
airflow, these switches are ideal for ToR
deployments connecting servers, storage,
and other switches, as well as for providing
compatibility for either hot aisle or cold aisle
data center designs. With dual-speed
functionality, each 1 GbE port also supports
10 GbE connections, providing the flexibility
needed to support a mixed environment as
data centers transition to higher bandwidth.

HIGH PERFORMANCE FOR
DATA CENTERS
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 connections,
Brocade VDX 6740, 6740T, and 6740T-1G
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 1 GbE and 10 GbE servers.

The 40 GbE uplinks can easily aggregate
high-bandwidth traffic and reduce
bottlenecks that occur when aggregating
multiple 10 GbE connections, keeping
data center networks working at
peak performance.

The switches also help maximize network
utilization with hardware-based Brocade ISL
Trunking. Organizations can create an
80 GbE trunk by utilizing two 40 GbE ports,
or a 160 GbE trunk with 16 10 GbE ports.
The Brocade trunk is automatically formed
between two Brocade VDX 6740, 6740T,
and 6740T-1G 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.

ADVANCED DESIGN DELIVERS
LOW LATENCY AND DEEP BUFFER
The movement toward server virtualization
has increased the quantity of VMs, data,
and applications that require processing.
This increase in traffic can create
performance and latency issues. The
Brocade VDX 6740, 6740T, and 6740T-1G
deliver very low latency through wire-speed
ports with 850 ns and 3 µs (respectively)
any-port-to-any port latency. In addition, the
switches deliver an industry-leading 24 MB
deep buffer per switch. 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. The Brocade
VDX 6740, 6740T, and 6740T-1G feature a
single ASIC design, instead of multiple ASIC
designs commonly found on other switches,
further improving performance and reducing
latency since all ports can communicate via
one ASIC.
