Hardware Profile Guide¶
This document explains the functionality of RAID and firmware configuration that is available in airshipctl. This will assist to author Baremetal Host documents with added RAID and firmware functionality.
The Host Generator M3 Function¶
Airshipctl has a
hostgenerator-m3 function which it uses to generate Metal3
Baremetal Host documents. This generator uses a
templatize a BMH specification. It takes a set of parameters and a template as
inputs and provides BMH documents as outputs, making it easier to generate
a large set of BMH documents efficiently.
The Example Hardware Profile¶
A Hardware Profile, in airshiptl terms, is a collection of parameters that comprise a hardware level configuration of a server. Currently, it contains RAID and firmware configurations. And later, this can be extended.
example hardware profile is one such set, which is available as a
reference for all the supported parameters. You can modify this to your liking
to generate hardwareprofiles that suit your environment.
The firmware parameters supported, in the example profile are as follows:
firmware: sriovEnabled: false virtualizationDisabled: false simultaneousMultithreadingDisabled: false
These are the default values, you can adjust to your liking
The RAID levels supported are 0, 1 and 1+0. Some examples of using these levels in your configurations are given
raid: hardwareRAIDVolumes: - name: "VirtualDisk1" level: "1+0" sizeGibibytes: 1024 numberOfPhysicalDisks: 4 rotational: False - name: "VirtualDisk2" level: "1" sizeGibibytes: 500 numberOfPhysicalDisks: 2 rotational: True - name: "VirtualDisk3" level: "0" sizeGibibytes: 500 numberOfPhysicalDisks: 2 rotational: True - name: "VirtualDisk4" level: "0" sizeGibibytes: 250 numberOfPhysicalDisks: 1 rotataional: False
For additional detail on these parameters, see the Baremetal Host doc.
