An Nlyte alternative for small data centers

At a glance

	Nlyte (as listed on its public pages)	DC Sim
What it is	Enterprise DCIM (Nlyte Asset Optimizer, Nlyte Energy Optimizer); a Carrier company	Browser-based data center simulator and 3D twin
Built for	Data centers, colocation, hybrid cloud and edge operators, from one facility to thousands of locations	Small and mid-size data centers and the partners who serve them
Price	By quote; not published	Monitor $5 per rack per month ($49 minimum); Design $490–3,900 one-time per project
Deployment	On premises or in the cloud	In the browser; connectors inside your network run in an agent that only dials out
How you start	Demo and quote through sales	Excel template today; walkthrough on your own file
Asset lifecycle, change management, workflows	Listed	Inventory from your sheet, NetBox or Zabbix; no asset or change workflows
Capacity planning	Space, power and cooling; model new deployments before installation; Cooling Capacity Planner	Design mode with U, weight, breaker and cooling checks and an N−1 audit
Power and environmental monitoring	Listed, including branch circuit monitoring	Reads Zabbix directly and any tool’s readings export; no own sensors
What-if	Power failure simulation listed (Energy Optimizer); scenario modelling for capacity	Fail any power, cooling, network, liquid or fire node; dark, one-feed and overloaded lists; estimated thermal impact
3D	3D Row View listed in a Nlyte webinar description	3D twin with Floor, Air, Water, Fire, Power, Cabling, Network, Device and Token layers
ITSM, CMDB, BMS	ServiceNow, BMC, Cherwell and other ITSM platforms; CMDB and BMS integrations	Not offered; NetBox and Zabbix connect directly
Liquid cooling and leaks	Not on the public pages	Liquid sheet: CDUs, manifolds, leak what-if (estimated)
Tokens per kWh	Not on the public pages	Token layer per server and rack

“Listed” means the feature appears on Nlyte’s public pages on the date checked; it is not a review of how well it works.

Price

Nlyte does not publish prices. Its pricing page names what a quote is based on: the size and number of facilities, infrastructure assets and power capacity, the modules required, the deployment model and integrations, and the support level. Without a public figure there is no side-by-side cost table here. DC Sim at list price:

Racks	DC Sim Monitor (per year)	DC Sim Design (one-time, if you plan a room or row)
10	$600	$490
20	$1,200	$490
50	$3,000	$1,490

When Nlyte is the better fit

• You need a DCIM system of record across many sites: asset lifecycle from receiving to disposal, capacity planning, change workflows and audit trails.
• Your service desk and CMDB must stay in sync with the physical estate, through ServiceNow, BMC, Cherwell or another ITSM platform, and your building management system feeds the same view.
• You want energy and branch circuit monitoring with standard reports across data centers, colocation and edge sites.

When DC Sim is the better fit

• A room of 5 to 50 racks where the main question is what fails with what, and how hot it gets, without a DCIM project.
• You want a published price: $5 per rack per month, or one-time per design project, with a 30 % margin for MSPs and integrators as partners.
• You want to simulate the layout before building: Design mode checks U, weight, breakers and cooling, and the N−1 audit runs the failure scenarios on a room that does not exist yet.
• Power and cooling capacity in one model: fail a UPS at peak or a cooling unit and see what goes dark and the estimated minutes to 27, 32 and 35 °C (zonal model, not CFD).
• Liquid, fire and tokens next to power and cooling, for AI rooms.

Using both

Keep Nlyte as the system of record. Export racks, devices, power and cables into the template sheets (Racks, Devices, Power, Cables) and import them into DC Sim to fail things in 3D; readings from any monitoring fit the Readings sheet. There is no direct Nlyte connector; NetBox and Zabbix connect directly (integrations).
