A server room where one switch, one link or one power feed can stop every application is not infrastructure — it is a bet. We engineer data center networks from your requirements, with the equipment brand chosen openly at design stage: a spine-leaf fabric where every path is doubled, servers dual-homed so any one device can fail without an outage, and an out-of-band management network that keeps you in control precisely when production is down — sized honestly at 2-4 racks, ~10 racks, or two rooms with disaster recovery between them.
Four patterns behind almost every emergency call we get:
Every path doubled, every device replaceable, and a way in that survives the outage itself:
Architecture drawn by AtlasCommTech following carrier-grade data center design practice. Diagram labels are kept in English for engineering clarity.
Why us: our founder spent 13 years inside the Huawei partner ecosystem delivering carrier networks — where a dropped link is a reportable incident. We bring that reflex to rooms of two racks as much as twenty.
The solution is sized to your requirements and budget first — the same architecture can be delivered on several vendors' product lines. We help you choose by supply availability in your destination country, budget and your team's operating habits.
Six properties a resilient fabric has that a stack of unmanaged switches never will:
Tell us your rack count and what runs in them — the tier tells you the shape of the fabric:
| Scale tier | Typical site | What the design includes |
|---|---|---|
| 2–4 racks | Company server room · hospital or campus machine room | A collapsed redundant switch pair instead of a full fabric, every server dual-homed, firewall pair at the border, UPS and out-of-band access — the no-single-point property without the box count. |
| ~10 racks | Growing company · hosting room · virtualization cluster | Two spines, a leaf per rack, dual-active uplinks everywhere, 10G/25G to servers with 40G/100G spine links, data center firewall pair, out-of-band management network, structured addressing and a written failover test plan. |
| Multi-room DR | Two rooms or two sites · regulated or downtime-sensitive business | Fabric per room plus a dedicated interconnect for replication, primary-standby roles with a rehearsed switchover runbook, out-of-band access to both rooms, and honest recovery targets agreed on paper before any hardware is ordered. |
The solution is built from these equipment categories — the brand is chosen with you at design stage. Exact models depend on your port speeds, rack count and country — so we spec models after your requirements list, not before.
| Role | What it does |
|---|---|
| Leaf / top-of-rack switches | Connect the servers and storage in each rack at 10G/25G, with dual-active uplinks to both spines; sized by server NIC count and speed. |
| Spine switches | The high-speed crossroads every leaf plugs into — 40G/100G ports, deployed in pairs so either one can fail or be serviced live. |
| Border router / DCI link | Connects the fabric to campus, WAN and — in DR designs — carries the replication link to the standby room. |
| Data center firewall pair | Polices traffic entering the fabric and between internal security zones; deployed as an active pair so inspection never becomes the single point of failure. |
| Out-of-band management switch | A small separate switch wired to every device's management and console port — your way in when the production network is the thing that broke. |
| Management platform | Fabric-wide topology view, alarms, configuration backup and change history — so the room survives staff turnover and 2 a.m. incidents alike. |
