Our primary goal is to deliver a high-performance and secure blockchain infrastructure that fosters trust and reliability. We aim to achieve this by focusing on the critical elements of blockchain technology - namely, ensuring high single-thread performance for validator services, and low latency for RPC services, among others.

Validator services in blockchain infrastructures demand high single-thread performance due to the nature of their operations. Validators, in essence, validate transactions and blocks within the blockchain. They act as the arbitrators of the system, ensuring the veracity and accuracy of the information being added to the blockchain. This is an intensive process that involves complex computations and encryption, thus requiring a high-performance, single-thread system to maintain efficiency.

The low latency required for our RPC services is another vital factor in our hardware design. RPC, or Remote Procedure Call, is a protocol that allows a computer program to execute a procedure in another address space, usually on another network, without the programmer needing to explicitly code for this functionality. In simpler terms, it's a way for systems to talk to each other. Low latency in these operations is crucial to ensure a smooth and seamless dialogue between various systems within the blockchain. A delay or a lag in these communications can cause bottlenecks, leading to a slowdown in overall operations.

The hardware components and their configurations we have selected are specifically designed to address these needs. By leveraging advanced technologies like the AMD Ryzen 9 7950X for its superior single-thread performance, DDR5 memory for fast data retrieval, and NVMe SSDs for their exceptional speed in data storage and retrieval, we aim to provide an infrastructure that can effectively handle the demands of blockchain technology.

Our infrastructure is also designed to ensure scalability and flexibility. As the demands of the blockchain ecosystem grow, so too should our capacity to handle these increasing demands. Hence, our hardware design also incorporates elements that will allow us to easily scale up our operations when necessary.

In essence, our hardware is purpose-built to deliver high-performance blockchain operations that are secure, reliable, and capable of scaling with the demands of the evolving blockchain ecosystem.

Proxmox Network Configuration Guide

Overview

Networking in Proxmox is managed through the Debian network interface configuration file at /etc/network/interfaces. This guide will walk you through the process of configuring the network interfaces and creating a Linux bridge for your Proxmox server.

Pre-requisites:

Before we begin, you should have:

  1. A Proxmox VE installed and configured on your server.
  2. Administrative or root access to your Proxmox VE server.

Step 1: Understand Proxmox Network Configuration Files

Proxmox network settings are mainly configured in two files:

  • /etc/network/interfaces: This file describes the network interfaces available on your system and how to activate them. This file is critical for setting up bridged networking or configuring network interfaces manually.
  • /etc/hosts: This file contains IP address to hostname mappings.

Step 2: Configure Primary Network Interface

First, open the network interfaces configuration file for editing: Set your primary network interface (e.g., enp9s0) to manual:

nano /etc/network/interfaces

auto enp9s0
iface enp9s0 inet manual

Step 3: Configure Linux Bridge

Next, create a Linux bridge (vmbr0):

auto vmbr0
iface vmbr0 inet static
    address 192.168.69.103
    netmask 255.255.255.0
    gateway 192.168.69.1
    bridge_ports enp9s0
    bridge_stp off
    bridge_fd 0

Make sure to replace the address, netmask, and gateway parameters with the correct values for your network.

Step 4: Apply Configuration

Save and exit the file, then restart the network service for the changes to take effect:

systemctl restart networking.service

Step 5: Verify Configuration

Use the ip a command to verify that the bridge was created successfully:

ip a

Step 6: Configure the Hosts File

The /etc/hosts file maps network addresses to hostnames. Open this file in a text editor:

nano /etc/hosts

Then, define the IP address and corresponding FQDN and hostname for your Proxmox server:

127.0.0.1	localhost
192.168.69.103	bkk03.yourdomain.com	bkk03

# The following lines are desirable for IPv6 capable hosts
::1     localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

Remember to replace 192.168.69.103, bkk03.yourdomain.com, and bkk03 with your server's IP address, FQDN, and hostname, respectively.

After updating the /etc/hosts file, save and exit the editor.

Important: Ensure the FQDN in your /etc/hosts matches the actual FQDN of your server. This FQDN should be resolvable from the server itself and any machines that will be accessing it. The Proxmox web interface uses this hostname to generate SSL certificates for the HTTPS interface, so incorrect resolution may lead to certificate issues.

By carefully following the instructions provided in this guide, administrators can ensure a robust and secure networking setup for their Proxmox servers. This guide should provide a good starting point for both new and experienced Proxmox administrators to understand and manage the network settings of their servers effectively.

Troubleshooting

If you run into issues during this process, you can use the following commands to troubleshoot:

  • systemctl status networking.service: Displays the status of the networking service.

  • journalctl -xeu networking.service: Provides detailed logs for the networking service.

  • ip addr flush dev <interface> and ip route flush dev <interface>: Clears IP addresses and routes on a given interface.

  • ip link delete <bridge> and ip link add name <bridge> type bridge: Deletes and recreates a bridge.

  • ip link set <interface> master <bridge>: Assigns an interface to a bridge.

  • ip addr add <ip>/<subnet> dev <bridge>: Assigns an IP address to a bridge.

Remember to replace <interface>, <bridge>, <ip>, and <subnet> with the appropriate values for your network.

For more detailed information about Proxmox networking, refer to the official Proxmox documentation.

Filesystem

Blockchain nodes, such as validators and archive nodes, require a highly reliable and efficient filesystem to operate effectively. The choice of filesystem can significantly affect the performance and reliability of these nodes. In light of performance concerns with ZFS, especially in ParityDB workloads as discussed in paritytech/polkadot-sdk/pull/1792, this guide provides a detailed approach to configuring a robust filesystem in Proxmox.

Filesystem Choices and Their Impact

The extensive use of I/O operations by blockchain nodes means the filesystem must manage write and read operations efficiently. CoW filesystems, while feature-rich and robust, introduce overhead that can degrade performance, as evidenced by the cited benchmarks.

Why Not ZFS or Btrfs for Blockchain Nodes?

  • ZFS: While ZFS is revered for its data integrity, the added overhead from features like snapshotting, checksums, and the dynamic block size can significantly slow down write operations crucial for blockchain databases.
  • Btrfs: Similar to ZFS, Btrfs offers advanced features such as snapshotting and volume management. However, its CoW nature means it can suffer from fragmentation and performance degradation over time, which is less than ideal for write-intensive blockchain operations.

Given these insights, a move towards a more traditional, performant, and linear filesystem is recommended.

For high I/O workloads such as those handled by blockchain validators and archive nodes, LVM-thin provisioned with ext4 stands out:

  • ext4: Offers a stable and linear write performance, which is critical for the high transaction throughput of blockchain applications.
  • LVM-thin: Allows for flexible disk space allocation, providing the benefits of thin provisioning such as snapshotting and easier resizing without the CoW overhead.

Strategic Partitioning for Maximum Reliability and Performance

A well-thought-out partitioning scheme is crucial for maintaining data integrity and ensuring high availability.

RAID 1 Configuration for the Root Partition

Using a RAID 1 setup for the root partition provides mirroring of data across two disks, thus ensuring that the system can continue to operate even if one disk fails.

Implementing RAID 1:

  1. Disk Preparation:

    • Select two identical disks (e.g., /dev/sda and /dev/sdb).
    • Partition both disks with an identical layout, reserving space for the root partition.

  2. RAID Array Creation:

    • Execute the command to create the RAID 1 array: 
      mdadm --create --verbose /dev/md0 --level=1 --raid-devices=2 /dev/sda1 /dev/sdb1
    • Format the RAID array with a resilient filesystem like ext4: 
      mkfs.ext4 /dev/md0
    • Mount the RAID array at the root mount point during the Proxmox installation or manually afterward.

Boot Partition Configuration

Having two separate boot partitions provides redundancy, ensuring the system remains bootable in the event of a primary boot partition failure.

Configuring Boot Partitions:

  • Primary Boot Partition:

    • On the first disk, create a boot partition (e.g., /dev/sda2).
    • Install the bootloader and kernel images here.

  • Fallback Boot Partition:

    • Mirror the primary boot partition to a second disk (e.g., /dev/sdb2).
    • Configure the bootloader to fall back to this partition if the primary boot fails.

LVM-Thin Provisioning on Data Disks

LVM-thin provisioning is recommended for managing data disks. It allows for efficient disk space utilization by provisioning "thin" volumes that can be expanded dynamically as needed.

Steps for LVM-Thin Provisioning:

  1. Initialize LVM Physical Volumes:

    • Use the pvcreate command on the designated data disks: 
      pvcreate /dev/nvme1n1 /dev/nvme2n1 /dev/nvme3n1

  2. Create a Volume Group:

    • Group the initialized disks into a volume group: 
      vgcreate vg_data /dev/nvme1n1 /dev/nvme2n1 /dev/nvme3n1

  3. Establish a Thin Pool:

    • Create a thin pool within the volume group to hold the thin volumes: 
      lvcreate --size 100G --thinpool data_tpool vg_data

  4. Provision Thin Volumes:

    • Create thin volumes from the pool as needed for containers or virtual machines: ```bash lvcreate --virtualsize 500G --thin data_tpool --name data_volume

  5. Format and Mount Thin Volumes:

    • Format the volumes with a filesystem, such as ext4, and mount them: 
      mkfs.ext4 /dev/vg_data/data_volume
mount /dev/vg_data/data_volume /mnt/data_volume

Integrating LVM-Thin Volumes with Proxmox

Proxmox's pct command-line tool can manage container storage by mapping LVM-thin volumes to container mount points.
