4. セットアップとインストール
4.1 安全上の注意
- Always wear an anti-static wrist strap when handling the RAID controller to prevent electrostatic discharge (ESD) damage.
- Ensure the server is powered off and unplugged from the power source before opening the chassis.
- Handle the card by its edges; avoid touching components or connectors.

4.2 ハードウェアのインストール
- サーバーを準備します。 Power down the server, disconnect all power cables, and open the server chassis.
- Locate a PCIe Slot: Identify an available x8 or larger PCI Express 2.0 slot on the server motherboard.
- コントローラーをインストールします。 Carefully align the ServeRAID M5015 card with the chosen PCIe slot and press down firmly until it is securely seated. Secure the card with the retention clip or screw provided by the server chassis.
- Connect SAS/SATA Drives: Connect your SAS or SATA drives to the Mini-SAS (SFF-8087) connectors on the controller using appropriate cables. Ensure proper cable routing for optimal airflow.
- サーバーを閉じます: Replace the server chassis cover and reconnect power cables.

5. 操作手順(設定)
After hardware installation, the ServeRAID M5015 requires configuration through its BIOS utility or a software management tool. Refer to your server's documentation for accessing the RAID controller's BIOS during boot-up.
5.1 Accessing the RAID BIOS Utility
- During server boot, watch for a prompt (e.g., "Press Ctrl+H to enter WebBIOS" or similar) to access the RAID controller's configuration utility.
- Follow the on-screen instructions to navigate the utility.
5.2 Creating a RAID Array
- From the main menu, select an option to 設定 or Create New Array.
- Choose the desired RAID level (e.g., RAID 0, 1, 5, 10, 50) based on your performance and redundancy requirements.
- Select the physical drives to be included in the array. Ensure that you do not mix SAS and SATA drives within the same array.
- Define the array parameters, such as stripe size and cache policy.
- Confirm the configuration and initialize the array. This process may take some time depending on the size and number of drives.
5.3 オペレーティングシステムのインストール
Once the RAID array is created, you can proceed with installing your operating system onto the logical volume presented by the RAID controller.
