Device Overview
● Hardware features...........................................................................................................15
● Hardware components.................................................................................................... 21
Hardware features
The following Brocade VDX 6940 devices extend VCS technology in a spine and leaf architecture:
• The Brocade VDX 6940-36Q provides up to 36 40 GbE quad small form-factor pluggable (QSFP)
ports for connecting devices in a VCS fabric. The base model of this 1U form-factor device contains
twenty-four 40 GbE ports. A single 40G Port Upgrade license can add 12 additional ports to provide
the full complement of 36 40 GbE ports. Each 40 GbE port can be reconfigured as four 10 GbE ports
in QSFP breakout mode to provide a total of 144 10 GbE ports for the device.
• The Brocade VDX 6940-144S provides up to 12 40 GbE quad small form-factor pluggable (QSFP)
ports and 96 fixed 10 GbE ports for connecting devices in a VCS fabric. The base model of this 2U
form-factor device contains 64 fixed 10 GbE base ports and no 40 GbE ports. Two 10G Port Upgrade
licenses can provide the full complement of 96 fixed 10 GbE ports in two 16-port increments. Two
40G Port Upgrade licenses provide up to 12 40 GbE ports in two six-port increments.
Multiple fan and power supply field replaceable units (FRUs) in these devices allow redundant operation
in the event of FRU failure.
A key feature of these devices is Brocade VCS™ technology, which includes virtual cluster switching, a
set of technologies that allows users to create flatter, virtualized, and converged data center networks.
VCS fabrics are scalable, permitting users to expand at their own pace, and simplified, allowing users to
manage the fabric as a single entity. VCS-based Ethernet fabrics are convergence-capable with
technologies such as Fibre Channel over Ethernet (FCoE) for storage.
4x10 GbE breakout mode support
Each 40 GbE port on the Brocade VDX 6940-36Q can be configured for breakout mode to provide four
10 GbE interfaces. The Brocade VDX 6940-144S does not support breakout mode at Network OS 6.0.1
release.
You can administer and operate the 10 GbE interfaces as any other SFP port. Optical and twinaxial
copper 4x10 GbE breakout cables provide a connection from the 40 GbE port to four 10 GbE SFP ports
on other devices. Breakout connections are primarily used for edge port connectivity, but can also
support ISL trunking with VDX 8770 and VDX 6740 platforms.
The 40 GbE ports support dynamic QSFP breakout configuration. For more information on configuring
breakout mode, refer to the Network OS Layer 2 Switching Configuration Guide.
For a information on QSFP transceivers that support 4x10 GbE breakout mode, refer to the online
matrices and data sheets referenced in Supported transceivers on page 17.
Brocade VDX 6940 Hardware Installation Guide 15
53-1003495-02

Brocade trunking support
Network OS supports Brocade trunks (hardware-based link aggregation groups, or LAGs). These
trunks are dynamically formed between two adjacent devices with connected interswitch link (ISL)
ports unless trunking is disabled on connecting ports. Traffic is evenly distributed along all links in a
trunk.
Brocade trunking is supported on the following port types:
• 10 GbE ports
• 40 GbE ports in 40 GbE mode
• 10 GbE interfaces when 4x10 GbE breakout mode is configured on 40 GbE ports. Note that 4x10
GbE breakout mode is only supported on the Brocade VDX 6940-36Q with Network OS 6.0.1.
Following are general limitations and considerations of this feature:
• Ports forming a trunk must be configured at the same speed as follows:
‐40 GbE ports configured in 40 GbE mode - 40 Gbps
‐10 GbE interfaces on 40 GbE ports configured in 4x10 GbE breakout mode - 10 Gbps. Note that
4x10 GbE breakout mode is only supported on the Brocade VDX 6940-36Q with Network OS
6.0.1.
‐10 GbE ports - 10 Gbps
• Ports forming a trunk must be in the same trunk group. Trunk groups are different for the Brocade
VDX 6940-36Q and Brocade VDX 6940-144S.
• Any port in a trunk group can belong to a specific trunk, but ports do not need to be contiguous. For
example, port 1, 2, and 7 can form a trunk with a remote device. If ports 3 and 4 are connected
later, they will form a separate trunk.
• The maximum number of ports that can form a trunk are as follows:
‐12 fixed 10 GbE ports
‐12 10 GbE interfaces on 40 GbE ports on Brocade VDX 6940-36Q in 4 x 10 GbE breakout mode.
‐Three 40 GbE ports (40 GbE mode)
• Trunking is not supported between Brocade VDX 6940 device 40 GbE ports and Brocade VDX
8770 devices when the 40 GbE ports are configured in 40 GbE mode. Trunking is supported on 40
GbE ports in 4x10 GbE breakout mode between the Brocade VDX 8770 and Brocade VDX
6940-36Q.
• 40 GbE and 10 GbE trunking is supported between Brocade Brocade VDX 6940 and Brocade VDX
6740 devices.
• MCAST LAG spraying is not supported on trunks.
• Standard 802.1ag LAG and Brocade vLAG functions are supported on fixed 10 GbE ports, 40 GbE
ports in 40 GbE mode, and on 10 GbE interfaces on 40 GbE ports when in 4x10 GbE breakout
mode. However, all ports in the LAG or vLAG must be configured at the same speed, 10 GbE or 40
GbE. If the port speeds do not match, the port will not be logically online and will fail to become a
member of the LAG or vLAG.
Ports forming a trunk must be in the same trunk group. The following tables show the port numbers
that belong to each trunk group for Brocade VDX 6940 devices. Colored labels attached above and
below ports on the port-side of the device designate ports that belong to the same trunk group.

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.

•Using the Brocade VDX 6940-144S as a spine device and Brocade VDX 6940-36Q as a leaf device
in medium-size VCS deployments. As a spine device, the Brocade VDX 6940-144S can uplink to a
core device, such as the Brocade VDX 8770, using its 40 GbE ports in 40 GbE mode. The fixed 10
GbE ports can downlink through a Brocade VDX 6940-36Q, functioning as a leaf device, to edge
nodes, such as servers.

Brocade VDX 8770. The Brocade VDX 6940-36Q40 GbE ports configured in 4x10 GbE breakout
mode to provide 10 GbE links and the fixed 10 GbE ports on the Brocade VDX 6940-144S can
downlink to edge nodes, such as servers.
