Fits into Any Data Center Design
VDX 6940-36Q and 6940-144S front access ports are
positioned to enable easy server or switch connectivity
and to simplify cabling. With a choice of front-to-back
or back- to-front airflow, these switches are ideal for
deployments connecting servers, storage, and other
switches, as well as for providing compatibility for either
hot aisle or cold aisle data center designs. For the 40 GbE
ports that also support 10 GbE connections with breakout
cables, the switches oer the flexibility needed to support
a mixed environment as data centers or service providers
transition to higher bandwidth.
VDX 6940 switches are designed to connect data centers
in multiple ways to meet individual design requirements.
This flexible design provides investment protection, giving
organizations a single switch that can support varying
data center requirements. The following features help
organizations meet their evolving needs:
• 10/40/100 GbE uplinks: The 40 GbE QSFP+ ports oer
the flexibility to expand and interconnect the network
infrastructure intelligently and eciently while reducing
bottlenecks. VDX 6940 switches oer the option to
separate each 40 GbE uplink into four 10 GbE uplinks
via breakout cables. As capacity and need increase,
organizations can revert to 40 GbE when ready.
• Ports on Demand: Ports on Demand (PoD) enables
organizations to activate additional ports. They can
purchase the number of ports that they currently need
and seamlessly scale up later by simply applying a
software license. This flexible and cost-ecient “pay as
you grow” licensing model solves scalability challenges
by allocating IT resources as needed.
Maximizes Network Availability with Eciency
and Resiliency
Extreme data center fabrics create a more ecient and
resilient network, and deliver the high performance and
high reliability required by modern data centers, including
cloud and highly virtualized environments.
