 # Validating with a Raspberry Pi: Mainnet advice
 
-Whether or not your Pi is up to the task will depend on a number of factors such as SSD speed, network connectivity, etc. So it's best to verify performance  on a testnet first.

 The best thing you can do is to set your Pi to run Pyrmont. **If you have no trouble syncing and attesting on Pyrmont, your setup should be more than good enough for mainnet** as well (Mainnet is expected to use fewer resources).

It is easy (and cheap) to get redundancy of components (even spare PIs in different locations, more of this to come).</p>&mdash; Ethereum on ARM (@EthereumOnARM) <a href="https://twitter.com/EthereumOnARM/status/1332772217420177408?ref_src=twsrc%5Etfw">November 28, 2020</a></blockquote> <script async src="https://platform.twitter.com/widgets.js" charset="utf-8"></script>
 
-Although we don't expect it to happen, we recommend buying a spare Pi, and enterprise grade SSD, on the off-chance yours fails. Keep your original SD around, so you can copy the image + Nimbus software quickly over to your spare SSD.
