Interface/Ports

100-GbE Ports	Up to 4 100-GbE QSFP28 ports; configuring each disables three 40-GbE ports
SFP+ GbE Ports	96 fixed 10-GbE ports supporting SFP+ and TSFP+ optics
QSFP+ GbE Ports	12 40-GbE QSFP+ ports; each breakable into four 10-GbE SFP+ ports for total 144 10-GbE ports

What is the maximum number of 10 GbE ports available on the VDX 6940-144S?

The switch provides 96 native 10 GbE SFP+ ports. Using breakout mode, the 12 40 GbE QSFP+ ports can each be broken into four 10 GbE ports, enabling up to 144 total 10 GbE ports. This flexibility allows operators to maximize port density based on deployment requirements.

Can I configure both 40 GbE and 100 GbE ports simultaneously?

No. The 12 40 GbE QSFP+ ports and 4 100 GbE QSFP28 ports share the same physical interfaces. Configuring each 100 GbE port disables three 40 GbE ports. Operators must choose between 40 GbE or 100 GbE uplink configurations based on their network architecture.

What is the switching fabric bandwidth and latency?

The VDX 6940-144S delivers 2.88 Tbps of full-duplex switching fabric bandwidth with 2.16 Bpps forwarding performance. Port-to-port latency is 700 nanoseconds, enabling non-blocking, line-rate switching across all ports. This performance supports latency-sensitive applications and high-throughput data center workloads.

How many VLANs and ACL entries does the switch support?

The switch supports up to 4,096 VLANs and 10,000 ACL entries, enabling complex multi-tenant network segmentation and granular security policies. These capabilities support enterprise-scale deployments requiring isolation between tenants and fine-grained traffic control.

What power supply configuration is included?

The VDX 6940-144S includes two internal, redundant, hot-swappable 1100W AC power supplies with load-sharing capability. Input voltage ranges from 90-264 VAC at 47-63 Hz. This redundant configuration eliminates single points of failure and ensures continuous operation during maintenance.

What is the physical form factor and airflow specification?

The switch is a 2U, 19-inch EIA-compliant rackmount chassis with dimensions of 3.4 inches height, 17.3 inches width, and 18.0 inches depth. It supports front-to-back or back-to-front airflow with maximum airflow of 370 cmh (218 CFM) and nominal acoustic noise of 69 dBA.

What operating system is pre-installed?

Brocade Network OS is pre-installed on the VDX 6940-144S, providing Layer 3 routing, advanced switching features, and comprehensive network management capabilities. The operating system supports the full feature set including VLAN management, ACL configuration, and port profiling.
