Next-Gen Data Centre Leaf-Spine Networks
Architect ultra-low latency 100G/400G Leaf-Spine Clos fabrics with VXLAN EVPN overlays, non-blocking backplanes, and automated network infrastructure as code.
High-Performance Networks for Mission-Critical Data Centres
Legacy three-tier data center networks suffer from Spanning Tree (STP) bottlenecks and latency spikes under heavy East-West virtualization and container traffic. Amrux Tech designs modern Leaf-Spine Clos switching topologies powered by Cisco Nexus and Arista EOS.
- Non-blocking 100G / 400G Leaf-Spine Clos network topologies.
- VXLAN EVPN overlay networks for multi-tenant cloud segmentation.
- Infrastructure-as-Code automation (Ansible, Terraform, Python).
- Direct Cloud Cross-Connects (AWS Direct Connect / Azure ExpressRoute).
Data Centre Visibility
Across leaf-spine fabrics, VXLAN EVPN overlays, server racks, and AI compute clusters.
Ultra-low latency 400G Leaf-Spine data centre switching.
Amrux engineers non-blocking data centre networks using VXLAN EVPN overlays, cut-through switching, and AI/storage cluster optimization.
Why Legacy 3-Tier Data Centre Networks Fail Modern Workloads
Heavy VM live-migrations and microservice communication choke legacy Spanning Tree topologies.
Spanning Tree (STP) Bandwidth Waste
Legacy STP blocks half of all redundant physical switch links to prevent loops, wasting 50% of available core network bandwidth.
- BGP-EVPN active-active multipathing
- Equal-Cost Multi-Path (ECMP) routing
- 100% link utilization
Manual VLAN Provisioning Delays
Manually configuring VLAN tags across dozens of top-of-rack switches slows server deployment and increases misconfiguration risks.
- VXLAN programmatic overlay
- Automated VLAN-to-VNI mapping
- GitOps network deployment
High Latency for AI & Storage
Slow switch backplanes delay NVMe-over-Fabrics storage traffic and AI cluster parameter synchronization.
- Cut-through switching latency (<800ns)
- RoCE v2 (RDMA over Ethernet) tuning
- Deep buffer telemetry
