# Tips and Suggestions * Enterprise grade servers can be bought second hand on Ebay for a lot cheaper * You don't need enterprise grade equipment to run a nodeRyzen 7, 32GB ram, at least 500 GB NVMe should be enough to run something * Most second hand servers come without rails and front disk pockets. You will need both * Some servers require extra cables, such as NVMe extenders or similar. Make sure to check that out first * [Awesome YT channel](< https://www.youtube.com/@cloudninjas>) to watch and learn before you buy anything * All servers need power supply. Research UPSs, PDUs, surge protectors and other similar devices to protect and power your equipment * Modular setups are more resilient. For example small networking devices can greatly benefit from an additional offline UPS, powering only that particular device * Servers have 2 power supplies for a reason. Ideally each one should be connected to a different input source * Think of powering networking devices, with an alternative input supply. If the power goes down, the nodes wont work without the network. * Automation (use existing software to ease your life) * Use open source tools. Find a [list here](/tools-and-more/resources.md) * Design cable management and your space in advance * Servers make noise. Be prepared. They also produce heat. You need to think about it in advance * "Do not put public and private (nodes) infrastructure in one basket". Your public endpoints should be separated networks * Physical security is as important as digital. Ideally, the server room should have 24/7 security, and limited physical access * Learn to read logs, don't guess. Learn to use packet tracing. Don't guess. Learn to monitor your nodes. Don't guess --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
