First ESXi Server Build with RAID: HP ProLiant DL360 Configuration

Installing VMware ESXi on an HP ProLiant DL360 requires configuring the Smart Array hardware RAID controller before booting the installer. The server must be set to UEFI mode, and the BIOS must recognize the virtual drive created by the P408i or similar controller. This process ensures that the hypervisor sees a single logical disk rather than individual physical drives, which is critical for data integrity and performance in a production environment.

Preparation and Hardware Requirements

Before beginning the installation, ensure you have the correct boot media. Download the latest ISO of VMware ESXi from the Broadcom support portal after acquiring your license. You will need to create a bootable USB drive using a tool like Rufus or UNetbootin. Set the USB drive to GPT partition scheme if your server supports UEFI, which is standard for modern DL360 models. Verify that the hard drives are seated correctly in the hot-swap bays. The HP ProLiant DL360 typically uses SFF (Small Form Factor) drives, but LFF versions exist. Ensure the backplane jumpers match the drive type installed. If you mix drive sizes or types within a single RAID array, it can lead to performance bottlenecks or configuration failures during the initialization phase.

Configuring RAID via HP Smart Storage Administrator

The most reliable method to configure RAID on this server is using the HP Smart Storage Administrator (SSA) utility built into the firmware. Restart the server and press F9 during the POST sequence to enter the System Utilities. Navigate to the Smart Storage Administrator option. This interface provides a graphical view of the controllers and physical drives. Select the Smart Array controller, such as the P408i-a SR Gen10. Choose the option to create a new logical drive. For redundancy, select RAID 1 if you have two drives, or RAID 5/6 if you have three or more. Assign a write policy of "Write Back" with Battery Backup Unit (BBU) protection enabled to maximize performance. If no BBU is present, use "Write Through" to prevent data loss during power outages. Set the read policy to "Read Ahead" for better sequential read performance. Confirm the configuration and initialize the logical drive. This step may take several minutes depending on the drive size. Do not interrupt this process. Once complete, exit SSA and return to the main menu.

BIOS and Boot Mode Configuration

Return to the F9 System Utilities menu and select System Configuration > BIOS/Platform Configuration (RBSU). Navigate to Platform Options > Boot Mode and Set to UEFI only. Disable Legacy Support unless you have specific legacy drivers that require it. Save changes and exit. When the system restarts, insert the bootable USB drive. Press F11 during POST to access the One-Time Boot Menu. Select the USB device from the list. If the installer does not appear, verify that the USB was created correctly and that the BIOS is set to UEFI. Some older versions of ESXi may require disabling Secure Boot in the BIOS settings if driver compatibility issues arise.

Installing ESXi

Once the installer loads, you will see a welcome screen. Press Enter to continue. Accept the End User License Agreement by pressing F11. Select the logical drive created by the Smart Array controller. It will appear as a VMware Virtual Disk. Do not select individual physical drives. Choose the default keyboard layout and set a strong root password. The installation will proceed automatically. This process typically takes 10-15 minutes. Upon completion, remove the USB drive and press Enter to reboot. The server will boot directly into the ESXi shell. After rebooting, note the IP address displayed on the console. Use a web browser to navigate to this IP address. Log in with the root credentials you set earlier. From here, you can manage virtual machines, storage, and network configurations through the vSphere Client.

Post-Installation Network Setup

Configure the management network interface by assigning a static IP address, subnet mask, and gateway. This allows remote access to the host. Enable SSH if command-line access is required for troubleshooting. Install the HP Management Agent if you wish to monitor hardware health through vCenter. For advanced networking, consider setting up VLANs on the virtual switches. This isolates traffic between management, VM, and storage networks. Ensure that the physical NICs are linked to the appropriate virtual switch ports. Proper network segmentation enhances security and performance.

Frequently Asked Questions

Can I install ESXi directly on individual physical drives without RAID?

Yes, but it is strongly discouraged for production environments. Installing on individual drives eliminates data redundancy, meaning a single drive failure results in total data loss. RAID provides fault tolerance and improved read performance through striping.

What should I do if the installer does not detect the hard drives?

This usually indicates that the RAID controller has not been initialized. Return to the F9 menu and run the Smart Storage Administrator again. Ensure a valid logical drive has been created and initialized. The ESXi installer only sees logical volumes presented by the HBA, not raw disks.

How do I update the firmware on the HP ProLiant DL360?

Download the Service Pack for ProLiant (SPP) ISO from HPE. Boot the server from the SPP ISO via the iLO virtual media or a mounted ISO. Run the Smart Update Manager (SUM) to update BIOS, RAID controller, and NIC firmware simultaneously. Always backup configuration before updating.

Is RAID 5 or RAID 6 better for larger drive counts?

RAID 6 is preferred for arrays with four or more drives because it tolerates two simultaneous drive failures. RAID 5 only tolerates one failure, which poses a higher risk during rebuilds with large capacity drives. Consider the rebuild time and I/O impact when choosing between these levels.

How can I monitor hardware health from within ESXi?

Install the HPE Management Agents package on the ESXi host. This integrates hardware sensors with vCenter Server, allowing you to view temperature, fan speed, and power supply status. Without these agents, ESXi cannot report detailed hardware metrics to the management platform.
