# Sourcing Data The Solana ledger is absolutely massive. In CAR format Understanding the requirements of your use-case and what data you require is a critical first step to provisioning an Old Faithful installation. There are several places you can get data from, each with their own varying degrees of complexity and hardware requirements. ## OF1 Triton One provides a complete copy of all the files required to run Old Faithful, called OF1. This archive is currently completely free to use, and is a great way to get started with Old Faithful. Read more about OF1 [here](/running-old-faithful/sourcing-data/of1.md). ## Generating from RocksDB Solana warehouse nodes archive the network ledger in a format called [RocksDB](https://rocksdb.org/). These archives can be used with the Yellowstone `radiance` fork to generate Old Faithful compatible CAR's. Read more about generating from RocksDB [here](#generating-from-rocksdb). --- # 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. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.old-faithful.net/running-old-faithful/sourcing-data.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
