Description

The Arista 7388X5 is a compact 4RU modular data centre switch for hyperscale cloud, AI/ML and I/O-intensive environments that need high-radix 400G leaf or spine switching. A single 25.6Tbps packet processor is fully connected to all 8 interface module slots with no oversubscription, and the switch runs Arista EOS.

This bundle provides 64 x 400G QSFP-DD ports without MACsec, with front-to-rear airflow. The platform delivers up to 10.66 billion packets per second with port-to-port cut-through latency as low as 825ns and a 114 MB dynamic shared packet buffer. The chassis has 8 interface module slots and 1 supervisor slot, with up to 4 hot-swappable 2400W power supplies in N+N and 5 fan modules in N+1. The supervisor has a quad-core x86 CPU, 32GB memory and a 512GB SSD. Supported scale includes 128-way ECMP, 800K IPv4 LPM routes and 128K MAC addresses.

It accepts 10G to 400G pluggable optics and cables through QSFP-DD interfaces, with existing 100G optics and cables usable. Interface modules DCS-7388-8D (8 x 400G QSFP-DD) and DCS-7388-16CD (16 x 100G/200G QSFP56) fit chassis DCS-7388-CH. Optional perpetual EOS feature licences are available for the Fixed Group 3 tier.

FAQs

Q: Does the 7388X5 need a software licence?
A: It runs Arista EOS with the base feature set bundled. Optional perpetual EOS feature licences for Fixed Group 3 are available, including LIC-FIX-3-E for Enhanced L3, LIC-FIX-3-Z for Monitoring and Automation, and LIC-FIX-3-V for Virtualization. CloudVision is a separate monthly subscription.

Q: Which power supplies does this chassis use?
A: It takes up to 4 hot-swappable 2400W power supplies in N+N redundancy: PWR-2421-HV-RED for 200-277 VAC or 240-380 VDC input, or PWR-2411-DC-RED for 40-72 V DC input. Maximum system power is 3,458 W in a fully loaded configuration with 15W optics.

Q: What optics and interface modules work with it?
A: The QSFP-DD interfaces accept 10G to 400G pluggable optics and cables, and existing 100G optics and cables can be used. Interface modules DCS-7388-8D (8 x 400G QSFP-DD) and DCS-7388-16CD (16 x 100G/200G QSFP56) fit chassis DCS-7388-CH.

Q: How does this SKU differ from other 7388X5 bundles?
A: DCS-7388X5-64DR-F provides 64 x 400G QSFP-DD ports without MACsec and with front-to-rear airflow. The airflow direction is fixed, as the platform has no reversible airflow option.

Q: Can the port speeds be changed?
A: Yes. The platform supports 400G, 200G and 100G operation, and speed changes from 400G to 100G are hitless.
