<sup>1</sup> Simplyblock highly recommends DDR5 memory on storage nodes for optimal performance.<br>
<sup>2</sup> It is possible to test with only one dedicated NVMe, but this is not approved for production.<br>
<sup>2</sup> Test setups require a minimum of 1 nvme. From 26.3., we support non-nvme device clusters (any SATA or SAS linux block device), this feature is still experimental.<br>
<sup>3</sup> The required number of nodes is only valid for erasure coding scheme 1+1.

Simplyblock auto-detects NUMA nodes. It will configure and deploy storage nodes per NUMA node.

Manual changes to the configuration are possible if the proposed configuration is not applicable.

It is recommended to deploy multiple storage nodes per storage host if there are more than 32 cores available
per socket.
For more information on simplyblock on NUMA, see [NUMA Considerations](numa-considerations.md).

During deployment, simplyblock detects the underlying configuration and prepares a configuration file with the
recommended deployment strategy, including the recommended amount of storage nodes per storage host based on the
detected configuration. This file is later processed when adding the storage nodes to the storage host.
Manual changes to the configuration are possible if the proposed configuration is not applicable.
