Example deployments
Smaller data-center deployments can initially deploy the Brocade VDX 6940-36Q as spine devices
and Brocade VDX 6740 as leaf devices, and as the data center grows, easily transition to a
heterogeneous deployment using Brocade VDX 6940-144S, Brocade VDX 6940-36Q. and Brocade
VDX 6740 devices to provide a scalable solution.
Following are example deployments for the Brocade VDX 6940-36Q and Brocade VDX 6940-144S:
• Using the Brocade VDX 6940-36Q or Brocade VDX 6940-144S as a spine device in smaller VCS
deployments.
The Brocade VDX 6940-36Q 40 GbE ports in 40 GbE mode can uplink to core
devices, such as the Brocade VDX 8770. 40 GbE ports configured in 4x10 GbE breakout mode to
provide 10 GbE links and the fixed 10 GbE ports ( Brocade VDX 6940-144S only) can downlink
through a leaf device, such as the Brocade VDX 6740, to edge nodes, such as servers.
