Supported Linux Distributions
Simplyblock requires a Linux Kernel 5.19 or later with NVMe over Fabrics and NVMe over TCP enabled. However, sbcli-pre,
the simplyblock commandline interface, requires some additional tools and expects certain conventions for configuration
files and locations. Therefore, simplyblock officially only supports Red Hat-based Linux distribution as of now.
While others may work, manual intervention may be required and simplyblock cannot support those as of now.

| Amazon Linux 2023 | - | x64, arm64 | Partially supported1 |
1 Amazon Linux 2 and Amazon Linux 2023 have a bug with NVMe over Fabrics Multipathing. That means that NVMe over Fabrics on any Amazon Linux operates in a degraded state with the risk of connection outages. As an alternative, multipathing must be configured using the Linux Device Manager (dm) via DM-MPIO.
