Multiple Rocket Pool nodes on a single computer

This guide will teach you how to run more than one Rocket Pool node on the same computer using Docker. The nodes will share an existing EL-CL client combination (unless you're using it to run a Testnet node on the same computer), so this solution is very lightweight and allows running many nodes at once. But before we start, let me tell you when:

You shouldn't use this guide...

• If you just want to run multiple Minipools on the same node. Rocket Pool can already do that.
• If you're using native mode. Sorry, but this guide relies on Docker magic.
• To run your fallback node on the same computer as your primary node. You won't get any hardware redundancy this way, and running two full EL+CL client pairs on one computer doubles some of the hardware requirements. Talk with with me ([object Object] on the Rocket Pool Discord) before attempting this.

Overview

Syncing an Ethereum node is largely reliant on latency and IOPS, I/O Per Second, of the storage. Budget SSDs will struggle to an extent, and some won't be able to sync at all. IOPS can roughly be used as proxy of / predictor for latency. Measuring latency directly is arguably better.

This document aims to snapshot some known good and known bad models.

The drive lists are ordered by interface and then by capacity and alphabetically by vendor name, not by preference. The lists are not exhaustive at all. @mwpastore linked a filterable spreadsheet in comments that has a far greater variety of drives and their characteristics. Filter it by DRAM yes, NAND Type TLC, Form Factor M.2, and desired capacity.

For size, 4TB is a very conservative choice. The smaller 2TB drive should last an Ethereum full node until at least sometime 2026, with the [pre-merge history expiry](https://hackmd.io/@hBXHLw_9Qq2va4pRt

• Grab all your wireguard configs from Mullvad and dump them in a folder. For this test, this folder is ~/wireguard/.
• Add the following function to generate a list of all servers you have configs for

lswg ()  { 
    ls ~/wireguard/ | cut -d '-' -f 2 | sed 's/\.conf//'
}

• Ping each server 10 times to determine latency.

lswg | xargs -I {} ping -c 10 {}-wireguard.mullvad.net | tee mullvadwgstats
