What is the maximum switching capacity of the HPE FlexFabric 12908E?

Up to 184 Tbps bi-directional switching capacity with 6 fabric module slots in a distributed architecture. Some configurations cite 92 Tbps or 46 Tbps, supporting non-blocking performance for high-density 1/10/40/100GbE ports up to 768 1/10GbE.

How many I/O slots and ports does it support?

Features 8 I/O module slots supporting up to 384 1/10GbE, 1/10GBASE-T, or 1GbE ports per slot, scaling to 768 1GbE/10GbE, 576 40GbE, or 128 100GbE with modules. Includes 2 MPU slots and 6 fabric slots.

What layer support and advanced features are included?

Full Layer 2 and Layer 3 with IPv4/IPv6, ACLs, QoS, MPLS/VPLS, multicast, VXLAN, TRILL, IRF, and OpenFlow 1.3 for SDN. Delivers up to 92.1 Bpps throughput for resilient data center fabrics.

What are the physical dimensions and form factor?

12U rack-mountable horizontal chassis measuring approximately 17.32" W x 33.74" D x 20.91" H, weighing 103.62 lbs. It's a 16-slot design with 8 I/O, 6 fabric, and 2 MPU slots for data center deployment.

What modules are required for operation?

Minimum 1 management module, 1 fabric module, and 2 hot-swappable load-sharing power supplies. Supports modular expansion for I/O, fabric, and processing units to achieve full performance.

Is it suitable for SDN and cloud environments?

Yes, SDN-enabled with OpenFlow 1.3, VXLAN, and TRILL for overlay networks. Ideal for virtualized data centers and clouds with high-density GbE/10GbE/40GbE/100GbE and fast convergence times.
