Design → Monitor in one tool
Lay out the room before it exists, with U, weight, breaker and cooling checks as you go. Publish a version, import the as-built, keep the same model as the running twin.

What it is
One Excel file. Nine layers. Fail any node.
DC Sim is a browser-based data center simulator. You import one Excel file with your racks, devices, power chain and cables, and get a 3D twin with floor, air, water, fire, power, cabling, network, device and token layers. Click any node, press Fail, and see which racks go dark and which services stop.
Three advantages
Three things nobody else gives you
On top of the monitoring you run
DC Sim does not replace your monitoring or DCIM. Zabbix and NetBox connect with a URL and a read-only token: inventory, readings and alarms become the twin. Every other tool comes in as a sheet export.
Zabbix · AvailableNetBox · AvailableDevice data that knows the hardware
Type the model the way the vendor prints it, or pick it from the catalog. It fills in size, weight, power, airflow and the parts inside; a device the catalog does not know you describe once and reuse.

Fill, import, fail.
- 01
Fill one Excel file
Devices is the only required sheet: rack, U and model per row. Cables, Racks, Power, Networks, Cooling and Readings each unlock another layer.
- 02
Import
Preview, a check list with 3D locations, apply. Re-upload later and see exactly what changed. Values only: formulas, macros and encrypted files are refused.
- 03
Fail things first
A scenario library built from your own model: feed loss, UPS, cooling, leak, fire, more load. Each run sits next to an untouched baseline.

What is DC Sim?
A browser-based data center simulator by Sensaka: one Excel import becomes a 3D twin with floor, air, water, fire, power, cabling, network, device and token layers, and any power, cooling or network node can be failed to see what goes dark.
Can I sign up today?
Not yet. The product runs today on demo data and on files you send us; we walk you through your own room on a call. Self-serve accounts and checkout are on the roadmap.
Do I have to install anything?
No. The twin runs in the browser. Zabbix and NetBox connect with a URL and a read-only token; inside your own network the same connectors run in a small agent that only dials out. Any other tool's export comes in as a sheet.
Is this CFD?
No. Air and water layers use a zonal model and every projected number is labelled estimated. It is built for questions like "what happens if this cooling unit stops", not for detailed airflow engineering.
How much does it cost?
Monitor is about $5 per rack per month with a $49 minimum. Design is one-time per project from $490. Integrators and MSPs earn a 30 % margin as partners.
Is there a Chinese edition?
Yes. The Chinese-language edition is distributed by our partner CloudSino.
