Description

The Arista DCS-7001-SUP-EL is a Supervisor-EL control plane module designed for the 7700R4 Distributed Etherlink Switch platform, optimised for large-scale AI/ML data centre deployments. Featuring an 8-core/16-thread x86 CPU at 2.3 GHz, 64GB RAM, and 512GB NVMe storage, this spare module supports 1+1 supervisor redundancy, stateful failover, and in-service software upgrades (ISSU) to keep critical workloads online. Built for hot-aisle/cold-aisle environments with front-to-rear airflow and secure boot enabled for hardened platform security.

Features

High-performance x86 control plane engineered for large-scale AI/ML data centre switching fabrics
- Secure Boot enabled by default for hardened platform security and trusted boot integrity
- Front-to-rear (-F) airflow supports standard hot-aisle/cold-aisle data centre rack deployments
- Designed for 1+1 supervisor redundancy within Arista 7001 Series systems
- Stateful supervisor failover minimises disruption during hardware failure events
- In-service software upgrades (ISSU) allow EOS updates without traffic interruption
- Runs Arista EOS for comprehensive control plane management and programmability
- Integrates with CloudVision for network-wide observability, telemetry, and automation
- Part of the 7700R4 Distributed Etherlink Switch platform optimised for AI/ML compute clusters

FAQs

Q: What chassis is the DCS-7001-SUP-EL compatible with?
A: The DCS-7001-SUP-EL is designed for use with Arista 7001 Series systems operating within the 7700R4 Distributed Etherlink Switch platform, a high-density fabric optimised for AI/ML accelerated compute and data centre interconnect deployments.

Q: Is this module intended as a spare or a standard order item?
A: This SKU is sold as a spare replacement module, making it suitable for keeping as a hot-standby unit or replacing a failed supervisor in an existing 7001 Series installation.

Q: Can the Supervisor-EL module be replaced without taking the system offline?
A: Yes. The DCS-7001-SUP-EL is a hot-swappable, field-replaceable module designed for 1+1 supervisor redundancy with stateful failover, enabling replacement without system downtime or disruption to critical workloads.

Q: What is the front-to-rear airflow designation?
A: The -F suffix indicates front-to-rear airflow, where cool air enters from the front (cold aisle) and exhausts out the rear (hot aisle), aligning with standard hot-aisle/cold-aisle data centre cooling configurations.

Q: What workloads does the 7700R4 platform support?
A: The 7700R4 Distributed Etherlink Switch platform is optimised for large-scale AI/ML accelerated compute clusters, supporting Ultra Ethernet, RDMA workloads, DCQCN, PFC, ECN, and Cluster Load Balancing for high-performance GPU and AI fabric deployments.
