WHY RACKPLANNER

Plan your infrastructure with real data, not guesswork

Every decision about your server involves money, time and risk. Our tools eliminate the uncertainty.

Save money by avoiding mistakes

Buying the wrong hard drive, an undersized UPS or a rack that doesn't fit costs hundreds. Our calculators help you get it right the first time.

Real technical data, not opinions

Every calculation is based on real manufacturer specs: exact RAID capacities, UPS battery curves, power consumption in watts and verified noise levels.

Interconnected tools

Your data flows between calculators. Configure a RAID and pass the consumption to the UPS calculator, or check if your NAS can transcode 4K on Plex before buying it.

100% free, no signup required

No account needed, no usage limits, no hidden premium version. All tools are instantly available in English and Spanish.

FAQ

Common server and rack questions answered

What RAID configuration is best for a home NAS?
It depends on your priority. RAID 1 is ideal for 2-disk mirror setups. RAID 5 offers the best balance between capacity and protection with 3+ disks. RAID 6 adds double parity for maximum safety. Use our RAID calculator to compare options with your specific drives.
How long will a UPS last with a Synology or QNAP NAS?
A typical 700VA UPS provides between 15 and 45 minutes of runtime for a NAS with 4 drives, depending on total consumption. Runtime isn't linear: a UPS at 20% load lasts much longer than at 80%. Our UPS calculator interpolates the real battery curve of each model for an accurate result.
Can my NAS transcode 4K video on Plex or Jellyfin?
Only if your NAS has an Intel processor with QuickSync (like the Celeron J4125 or N5105). NAS units with AMD or ARM processors can't hardware-transcode 4K, though they can Direct Play if your client supports it. Our transcoding checker analyzes the exact CPU in your model.
How loud are NAS hard drives?
A typical NAS drive like the WD Red generates about 28 dB individually, but 4 drives together don't add up to 112 dB — decibels combine logarithmically, resulting in about 34 dB. Our noise simulator calculates this correctly and compares it to references like a library (30 dB) or an office (40 dB).
What rack size do I need for my server?
A 12U rack is the most popular. It fits a NAS (2U), switch (1U), patch panel (1U), UPS (2U) with 6U to spare for expansion. If space is limited, an open 6-9U rack may be enough. Our visual configurator lets you drag components and verify everything fits.
