Description

The 7388X5 series is Arista's modular platform for hyperscale and AI data centre leaf and spine deployments. This is the empty 4RU chassis with one supervisor slot and eight interface-module slots, built for large-scale cloud networks, AI/ML clusters, big data farms and serverless compute environments.

With the DCS-7388X5-SC switch card and interface modules fitted, the system scales to 64 x 400G, 128 x 200G or 128 x 100G ports at up to 25.6 Tbps and 10.66 Bpps, with latency from 825 ns and a 114 MB shared packet buffer. The chassis has four power supply slots in an N+N arrangement and five fan modules in N+1, with front-to-rear airflow. It runs Arista EOS with Fixed Group 4 feature licences, and the minimum EOS release is 4.29.1.

The chassis takes the DCS-7388-SUP supervisor, the DCS-7388X5-SC switch card, FAN-7012HP-RED or FAN-7012MP-RED fan trays and PWR-2421-HV-RED 2400W power supplies. Supported interface modules are the DCS-7388-16CD2, DCS-7388-8DR and DCS-7388-8D.

FAQs

Q: What do I need to make this chassis operational?
A: The empty chassis needs the DCS-7388-SUP supervisor, a DCS-7388X5-SC switch card, FAN-7012HP-RED or FAN-7012MP-RED fan trays and PWR-2421-HV-RED power supplies. Interface modules are then added to the eight module slots.

Q: Which interface modules does it support?
A: The DCS-7388-16CD2 (16 x QSFP56), DCS-7388-8DR (8 x QSFP-DD) and DCS-7388-8D (8 x QSFP-DD with MACsec). The blank covers are DCS-7388-PCVR and DCS-7388-LCVR.

Q: What power supplies does it use?
A: It takes up to four PWR-2421-HV-RED 2400W HV AC/DC power supplies in an N+N hot-swappable arrangement. Maximum system power is 3,458 W for a fully loaded configuration.

Q: How is EOS licensed on this platform?
A: The 7388X5 uses Arista EOS with Fixed Group 4 feature licences. Optional licences include LIC-FIX-4-E (Enhanced L3), LIC-FIX-4-Z (Monitoring and Automation), LIC-FIX-4-V (Virtualization) and LIC-FIX-4-MACSEC. The minimum EOS release is 4.29.1.

Q: What maximum port density can this chassis reach?
A: With the DCS-7388X5-SC switch card and interface modules fitted, it supports up to 64 x 400G, 128 x 200G or 128 x 100G ports at up to 25.6 Tbps.
