What is the maximum switching capacity of the HPE FlexFabric 7904?

The HPE FlexFabric 7904 Switch Chassis (JG682A) offers 3.8 Tbps switching capacity and up to 2.3 Bpps throughput in a nonblocking lossless Clos architecture with VOQs. This supports high-density configurations like 48x40GbE or 192x10GbE ports, ideal for data center core switching with large buffers and wirespeed performance.

How many I/O slots and port options does it have?

It features 4 I/O module slots supporting maximum 48x40GbE ports, 192x10GbE ports, 96x1/10GbE ports, 8x100GbE ports, or combinations. The compact 2U design provides high density versus traditional chassis, with jumbo frames up to 12288 bytes for efficient data handling.

What SDN and overlay features are supported?

Supports OpenFlow 1.3, VXLAN, VMware NSX federation, TRILL, and IRF for large Layer 2 scaling. Includes SDN App Store and SDK for programmability, enabling automated fabrics in virtualized and cloud environments with full Layer 2/3 capabilities.

What are the physical dimensions and weight?

Dimensions are 44 cm width x 72 cm depth x 8.81 cm height in a 2U rack-mountable form factor. Chassis weight is 17.9 kg, with mid-plane free design for optimal airflow and reliability via direct fabric card connections.

What management interfaces are available?

Management via IMC, command-line interface, out-of-band serial RS-232C, Telnet, terminal, and modem interfaces. SNMP manager with IEEE 802.3 Ethernet MIB and Ethernet interface MIB support simplifies network operations and monitoring.

What are the environmental operating conditions?

Operates at 0 to 40°C temperature and 10 to 95% noncondensing humidity. Voltage input is 100-120/200-240 VAC, suitable for standard data center power environments with front-to-back airflow options.
