The installer first gathers information about the system and available drives, including the Platform Name and System Manufacturer. Additionally, it collects data on the drives found: the Hardware RAID drive, the VirtIO drive (in a KVM VM), and a list of SATA and NVMe drives. Based on this information, the SynetoOS 6 installer utilizes a specific hierarchy of checks to determine the target drive for the Operating System.

 

1. Syneto Platforms

The installer initiates the selection process by verifying whether the hardware is a native Syneto platform, ensuring the OS is deployed according to factory-certified specifications.


Identification Workflow

The installer queries the system BIOS: if the manufacturer is identified as "Syneto", the appliance logic is triggered. The Platform Name is then compared against an internal registry of supported models (e.g., HYPER-Core-1000-G5Plus, HYPERSeries-G3).


Predefined Installation Rules

Once a model match is confirmed, the installer applies installation rules tailored to the Hyperion architecture, and validating mandatory prerequisites (e.g., "Minimum of 2x SATA drives required").


Drive Configuration

Based on the model, the installer automatically selects the optimal boot layout:

  • Single Drive: Standard deployment on one identified disk.
  • 2-way md-mirror (Software RAID1): Mirrored installation across two identical SATA or NVMe drives for redundancy.

IMPORTANT 
If the requirements do not meet these criteria or if drive sizes are mismatched, the process prints an ERROR and terminates.

 

2. Manufacturer-Specific Platforms

If the system is not a Syneto platform, the installer checks for the following major manufacturers; if none is detected, an ERROR (Bailing out) occurs.

Platform 1x HW RAID 2x NVMe 2x SATA 1x NVMe
Dell
Lenovo
HPE

 

3. Generic Fallback (Unknown Platforms)

If the system is detected as an Unknown platform, it applies a tiered, generic fallback approach to identify the best available drive.

Detected Drive Type Result
Hardware RAID Single-drive installation
VirtIO Drive Single-drive installation (KVM >80GB)
Dual NVMe md-mirror (RAID 1) installation
Dual SATA md-mirror (RAID 1) installation
Single NVMe Single-drive installation
Single SATA Single-drive installation
Default Fallback Single-drive installation on /dev/sda

Once a drive or drive pair is selected, the installer generates the necessary partition commands to proceed with the OS installation.
