Not sure how much power or runtime you need? For multiple racks, dual power supplies, redundancy or longer backup times, we recommend requesting technical sizing through the form.
Sizing
Four questions help determine the right UPS
ERREPI works with you to determine which systems must keep running, which should shut down in a controlled way, and how to account for rack installation, monitoring, bypass and future service.
Planning also covers the connections between servers, storage and network devices. This helps you plan power and shutdown for server rooms and networks.
Which loads are critical?
Servers, storage and network devices are assessed separately. Measurements, power supply ratings and planned expansions help establish the requirements.
What is the runtime goal?
A UPS can bridge short interruptions, provide time for an orderly shutdown or continue supplying power until a backup source takes over.
How will the UPS be installed?
Rack depth, rack units, weight, airflow, connections and power distribution affect the choice.
How will the system be operated?
Planning covers monitoring, alarms, shutdown sequence, bypass, battery replacement and responsibilities.
Choosing a system
What to clarify before requesting a quote
| Application | Assessment |
|---|---|
| Servers, storage, firewall and switches | Record loads and dependencies together |
| A single rack or a small server room | Assess rack or floor-standing options against load, space and runtime |
| Multiple racks or planned growth | Compare reserve capacity, distribution and central or distributed power supply |
| Servers with dual power supplies | Define the power supply concept and required redundancy first |
| Backup generator available | Coordinate generator operation and required backup time |
| Cooling, laser printers or other high loads | Assess separately rather than connecting them to the server UPS as a matter of course |
Steps
From initial requirements to a suitable solution
- 01
Record the connected loads
Send existing load data, equipment lists or a short description of your critical IT.
- 02
Define the protection goal
Together, we establish what must keep running and what should shut down in a controlled way.
- 03
Size the UPS system
Power, runtime, reserve capacity, installation, monitoring and bypass are assessed for your project.
- 04
Discuss the quote
ERREPI uses this assessment to discuss the quote with you and clarify any outstanding technical or organisational points.
Helpful information
What to include in your first enquiry
- Servers, storage and network devices
- Measurements or power supply ratings
- Number and layout of racks
- required backup time
- shutdown or continued-operation goal
- existing backup generator
- rack space and power distribution
- monitoring and alarm requirements
- maintenance or bypass requirements
- planned expansions
You can start with incomplete information. ERREPI will help establish what else is needed for further sizing.
FAQ
Common questions about server-room UPS systems
How large does a server-room UPS need to be?
The number of servers alone does not determine this. The actual load, required runtime, reserve capacity and behaviour of connected systems are decisive.
Does a server room always need an online UPS?
The right topology depends on the loads, protection goal and existing power supply. ERREPI assesses these factors before making a recommendation.
Should the UPS maintain power or enable a shutdown?
Both are possible. Define the goal before sizing, as it affects the required runtime, battery and integration.
How are servers, storage and network devices shut down safely?
The sequence depends on service dependencies. Monitoring and shutdown communication are therefore planned together with the power supply.
When is an external maintenance bypass useful?
A maintenance bypass can make servicing or replacement easier. Whether one is needed depends on the power supply concept, system and operational requirements.
Can existing UPS systems be replaced or expanded?
Yes. Details of the existing model, current load, installation and reasons for replacement or expansion help with the assessment.
