What is the maximum number of 10GbE ports available on the VDX 6940-64S?

The base configuration provides 64 fixed 10GbE SFP/SFP+ ports. Using 4x10 breakout cables on the 12 40GbE QSFP+ ports adds 48 additional 10GbE ports, totaling 144 10GbE ports maximum. This flexibility allows customers to optimize port allocation based on workload requirements.

Does this switch support 100GbE connectivity?

Yes. Up to 4 of the 40GbE QSFP+ ports can be configured as 100GbE QSFP28 ports using qualified 100GbE transceivers. However, each 100GbE port configured disables three 40GbE ports, so maximum 100GbE deployment uses all 4 ports with no 40GbE operation.

What is the switching fabric bandwidth and latency?

The VDX 6940-64S provides 2.88 Tbps switching fabric bandwidth with 2.16 Bpps forwarding performance and 700ns port-to-port latency. This non-blocking architecture ensures deterministic performance across all ports simultaneously, critical for latency-sensitive applications.

How many VLANs and routes does this switch support?

The switch supports 4,096 VLANs, 12,000 IPv4 unicast routes, and 3,000 IPv6 unicast routes. It also maintains 112,000 MAC address table entries and 84,000 ARP entries, enabling large-scale multi-tenant and segmented network deployments.

What power supply options are available?

The BR-VDX6940-64S-AC-R model includes two internal redundant field-replaceable AC power supplies with load-sharing capability. Input voltage range is 90-264 VAC at 47-63 Hz, supporting global data center deployments without voltage conversion.

Is this switch FIPS 140-2 certified?

Yes, the VDX 6940 series is FIPS 140-2 certified as a multi-chip standalone cryptographic module. It also meets RoHS-6 compliance with lead exemption and NEBS requirements, suitable for regulated and carrier-grade environments.

What operating system is pre-installed?

Brocade Network OS is pre-installed on the VDX 6940-64S, providing comprehensive Layer 3 switching, routing, and advanced networking features. The OS supports In-Service Software Upgrade (ISSU) for zero-downtime maintenance and updates.
