HYDRA B2-12T8-32H (Tomahawk, Bare-Metal)

Is a high-density 400GbE switch capable to meet tomorrow’s data center scale and bandwidth. The next-gen Hyperscale fabrics will rely on 400GbE avoiding costly topology changes and diving deeper into IO intensive workloads such as Deep Learning and NVMe storage networks.

32 QSFP-DD interfaces are backward compatible with QSFP28 and provide a flexible solution for any data center, enterprise, or CSP environment supporting break-out configuration with up to 128x 100G ports.

Consistent latency and 12.8Tbps throughput deliver wire-speed Layer 2 and Layer 3 performance. Traffic instrumentation, automation, and visibility features are the key to managing the massive scale and bandwidth of the upcoming networks.

The system has BMC (Baseboard Management Controller) embedded to provide server-style management in the Ethernet switch. Besides the health monitoring of the temperature, power status, and cooling fans; BMC also aids in the deployment and management of software and hardware assets.

Key features
  • New Elephant Flow feature can detect high-bandwidth, long-lived flows and take QoS actions to protect Mice Flows
  • More than doubles the IP route forwarding scale compared to previous Aurora devices
  • Dynamic Load Balancing and Dynamic Group Multipathing enhance ECMP
  • New shared-buffer architecture offers 4X higher burst absorption and improved performance for ROCEv2 workloads
  • Over 40 percent reduction in power per port compared to previous Tomahawk devices
Simplified deployment
  • With full Open Network Install Environment (ONIE) support, network operators can install the target Network Operating Systems (NOS) as part of data center provisioning, in the fashion that servers are provisioned.
Network monitoring
