 WIP Tezos Octez node setup and baking OVH x softstack x Tezos
+
+This is the documentation for setting up a Tezos Baker/Validator node with a server from [OVH](https://www.ovh.com).
+## Requirements
+- High CPU performance for transaction processing
+- Sufficient memory to handle blockchain data and operations
+- Fast and reliable storage with SSD
+- Good network performance
+
+In numbers:
+- 8 GB RAM
+- 2 CPU cores (better 4 vCPU)
+- Min. 256 GB SSD Drive
+- Linux (Docker optional)
+- Network min. 100 Mbps
+
+History types for a node:
+- **Rolling mode:** The most lightweight mode. It stores recent blocks with their current context.
+- **Full mode (default mode):** It also stores the content of every block since genesis so that it can handle requests about them, or even recompute the ledger state of every block of the chain.
+- **Archive mode:** Also stores the history of the context, allowing services like indexers to enquire about balances or staking rights from any past block.
+
+Network types:
+- Mainnet
+- Oxfordnet was a testnet. Seems to be deprecated.
+- Ghostnet is a permanent testnet for devs or bakers.
+
+The node is intended for baking with no need to store content of every previous block. This is why the history type can be in **rolling** mode. Network type must be **mainnet**.
+
+## Select OVH server
+
+1. Got to [ovh.com](https://www.ovh.com)

+
+3. Select *Hardware* filter 
+- Select min. **16GB** RAM
+- Select **NVMe** storage for SSD
+- Select min. **256GB** storage
+![[3-select-hardware.png]]
+
+4. Select suitable server

+
+## Deployment of a tezos node
+
+1. Choose ovh server: **SYS-4-SSD-16** 
+2. Login to server with ssh. Perform ssh hardening.
+3. Installation and Setup of a node
+4. Keep octez up to date
+5. Monitor performance and activity
