The Solution Admin Host (SAH) is a physical server that hosts one VM, the Red Hat OpenStack Director as the Undercloud.
The SAH BIOS configuration must be configured prior to OpenStack deployment. Refer to SAH BIOS specification.
The SAH is configured using the Open Source hardware configuration toolkit (OS-HCTK) tool.
Please contact your Dell EMC Sales or Professional Services representative for access to the toolkit.
Open Source hardware configuration toolkit
The Open Source hardware configuration toolkit (OS-HCTK) is a configuration utility with sample scripts and configuration files that is used to automate the setup and configuration of BIOS and RAID settings for Dell EMC servers used for OpenStack open source software solutions.
The OS-HCTK allows a user to create a USB key from which a Dell EMC PowerEdge R640 can be booted and the BIOS and RAID settings can be applied.
