Hello @Pakpoom Chatsuwan (ED)
Welcome to the world of Azure Stack HCI! It's great that you're exploring this solution as an alternative to VMware vSphere. Let's ensure you're on the right track for setting up your environment.
Setting Up Azure Stack HCI
- Download the Azure Stack HCI Operating System:
- First, download the Azure Stack HCI operating system from the Azure portal.
- You'll need this OS image to install on your server.
- Installation Process:
- Start the Install Azure Stack HCI wizard on the system drive of the server where you want to install the operating system.
- Choose the language to install or accept the default language settings.
- Select "Install now" to proceed.
- Review and accept the license terms.
- On the installation type page, select Custom: Install the newer version of Azure Stack HCI only (advanced).
- Confirm the drive on which the operating system will be installed.
- The installation process will restart the operating system twice to complete the process.
- Change the user's password before signing in to the operating system using the Server Configuration tool (SConfig).
- Resiliency Options:
- Azure Stack HCI uses Storage Spaces Direct (S2D) for fault tolerance, implemented in software (similar to RAID).
- There are two main options for resiliency: mirroring and parity. Mirroring:
- Provides fault tolerance by keeping multiple copies of all data (similar to RAID-1).
- Choose between two-way (50% storage efficiency) or three-way mirroring (33.3% storage efficiency).
- Three-way mirroring can tolerate at least two hardware problems (drive or server) simultaneously. Parity (erasure coding):
- Provides fault tolerance using bitwise arithmetic.
- Better storage efficiency without compromising fault tolerance.
- Choose between single parity (50% storage efficiency) or dual parity (advanced technique with local reconstruction codes at larger scales).
- OS Disk Redundancy:
- Since you cannot use hardware RAID cards, Azure Stack HCI relies on software-based redundancy.
- Your OS disk is already redundant due to the underlying Storage Spaces Direct technology.
- No additional setup is needed for OS disk redundancy; it's inherent in the Azure Stack HCI architecture.
- Best Practices:
- Ensure that your local administrator password follows Azure password length and complexity requirements.
- Use a password that is at least 12 characters long and contains a lowercase character, an uppercase character, a numeral, and a special character.
- Regularly monitor your environment and follow Azure Stack HCI best practices for optimal performance and reliability.
Remember, Azure Stack HCI provides a flexible and resilient platform for your workloads. If you have any further questions or need assistance, feel free to ask! 😊
