Install Simplyblock

Installing simplyblock for production requires a few components to be installed, as well as a couple of configurations to secure the network, ensure the performance, and data protection in the case of hardware or software failures.

Simplyblock provides two test scripts to automatically check your system's configuration. While those may not catch all edge cases, they can help to streamline the configuration check. This script can be run multiple times during the preparation phase to find missing configurations during the process.

Automatically check your configurations
# Configuration check for the control plane (management nodes)
curl -s -L https://install.simplyblock.io/scripts/prerequisites-cp.sh | bash

# Configuration check for the storage plane (storage nodes)
curl -s -L https://install.simplyblock.io/scripts/prerequisites-sn.sh | bash

Before We Start

A simplyblock production cluster consists of three different types of nodes:

  1. Management nodes are part of the control plane which managed the cluster(s). A production cluster requires at least three nodes.
  2. Storage nodes are part of a specific storage cluster and provide capacity to the distributed storage pool. A production cluster requires at least three nodes.
  3. Secondary nodes are part of a specific storage cluster and enable automatic fail over for NVMe-oF connections. In a high-availability cluster, every primary storage node automatically provides a secondary storage node.

A single control plane can manage one or more clusters. If started afresh, a control plane must be set up before creating a storage cluster. If there is a preexisting control plane, an additional storage cluster can be added to it directly.

More information on the control plane, storage plane, and the different node types is available under Simplyblock Cluster in the architecture section.

Network Preparation

For network requirements, see System Requirements.

Simplyblock recommends two individual network interfaces, one for the control plane and one for the storage plane. Hence, in the following installation description, we assume two separate subnets. To install simplyblock in your environment, you may have to adopt these commands to match your configuration.

Network interface Network definition Abbreviation Subnet
eth0 Control Plane control 192.168.10.0/24
eth1 Storage Plane storage 10.10.10.0/24
