Arista ACE Specialist - Data Center case studies
Arista ACE Specialist - Data Center · Put your knowledge to work in context.
The Arista ACE Specialist - Data Center is a vendor credential for network engineers who design, build, and operate Arista-based data center fabrics. It is aimed at practitioners with hands-on exposure to leaf-spine architectures, Arista's Extensible Operating System (EOS), and the CloudVision management platform, rather than at candidates seeking a general networking certification. The exam is organized into four equally weighted domains: Data Center Networking Fundamentals; Arista EOS Configuration and Operations; CloudVision and Network Automation; and Data Center Design, Routing, and Troubleshooting. Each domain carries roughly a quarter of the content, so no single topic can be skipped without risking the overall result. The Arista ACE Specialist - Data Center case studies are 5 cases and about 2,369 words.
1MLAG Peer Link Saturation During Storage Rebuild
A two-switch MLAG pair (leaf-01/leaf-02) serves 24 servers across two 40G MLAG bonds each. A storage cluster rebuild begins after a drive failure; the affected server pair pushes ~38 Gbps sustained across its bond for 40 minutes.

A leaf-spine fabric has 4 spines and 16 leaves, all 100G, with ECMP across the spines (4-way per leaf). A new analytics workload runs a single large TCP flow from a source on leaf-03 to a destination on leaf-11.

An Arista EVPN/VXLAN fabric uses two spine route reflectors (RR-1, RR-2) for the underlay and overlay BGP. All 20 leaves peer with both RRs.
