Force10 ExaScale Switch vs. Cisco Nexus 7000 Switch
Sat, 9/18/10 - 7:27pm    View comments

Force10CiscoForce10 Networks commissioned Tolly to evaluate the energy consumption of the Force10 ExaScale E-Series E1200i Core Switch/Router vs. the Cisco Nexus 7000 Series 18 and the Juniper EX8216.

View Cisco vs. Competitor lab tests.

Tolly's 3 Key Findings:

1. Force10 provides higher density line-rate GbE and 10GbE configurations than Cisco or Juniper.
2. With Gigabit Ethernet, Force10 consumes 52% less power than Cisco and 22.5% less power than Juniper in Watts per Gbps of throughput.
3. With 10 Gigabit Ethernet, Force10 consumes 56% less power than Cisco and 29% less power than Juniper in Watts per Gbps of throughput.

Note: The Cisco and Juniper devices were not tested. Typical energy consumption calculation were based on data provided by each vendor on its company website. While no testing was conducted of Cisco or Juniper products, Tolly did offer to share the energy consumption model with each vendor.

Cisco offered corrections to its configuration which are integrated into the published model.

A Juniper representative stated that "We are not endorsing any comparisons not based on actual measurements." The Juniper representative also noted that Juniper supports only two measurement methodologies: ATIS-TEER and ECR

So according to Tolly's test, the Force10 ExaScale configured with the maximum possible 140 10GbE ports consumed ~5,000W less energy than the Cisco Nexus 7000 and ~1,350W less energy than the Juniper EX8216. Outfitted with 10GbE ports, the Force10 ExaScale drew only 3.34W per Gbps of throughput compared with calculations of 7.59W for the Cisco Nexus 7000 and 4.69W for the Juniper EX8216 (see below Figures 1, 2 as well as Table 1):
