Introduction
This manual provides detailed instructions for the IBM 81Y4494 ServerRAID H1110 SAS/SATA Controller. It covers the necessary steps for proper installation, configuration, operation, and troubleshooting to ensure optimal performance and longevity of your hardware. Please read this manual thoroughly before attempting any installation or operation.
Setup and Installation
Proper installation is crucial for the functionality of the IBM 81Y4494 ServerRAID H1110 controller. Follow these steps carefully.
1. Safety Precautions
- Always disconnect power from the server before opening the chassis.
- Wear an anti-static wrist strap to prevent electrostatic discharge (ESD) damage to components.
- Handle the controller by its edges; avoid touching components or connectors.
2. Physical Installation
- Open Server Chassis: Power down the server and disconnect all power cables. Open the server chassis according to the server manufacturer's instructions.
- Locate PCIe Slot: Identify an available PCI Express (PCIe) slot on the server's motherboard. The IBM 81Y4494 requires a PCIe x8 or x16 slot for full bandwidth, though it can operate in a smaller slot if physically compatible.
- Remove Slot Cover: Carefully remove the metal slot cover corresponding to the chosen PCIe slot.
- Insert Controller: Align the controller with the PCIe slot. Apply even, firm pressure to seat the card fully into the slot. Ensure the retention clip or screw secures the card.

- Connect SAS/SATA Cables: Connect the appropriate SAS or SATA data cables from your storage devices (hard drives, SSDs) to the ports on the IBM 81Y4494 controller. Ensure secure connections.
- Close Chassis: Once all connections are made, close the server chassis and reconnect power cables.
3. Driver Installation
After physical installation, power on the server. The operating system may automatically detect and install a generic driver. For optimal performance and full functionality, it is recommended to download and install the latest drivers from the official IBM support website for your specific operating system.
- Visit the IBM Support website.
- Search for "81Y4494" or "ServerRAID H1110".
- Download the appropriate driver package for your server's operating system.
- Follow the provided instructions for driver installation.
Operating the Controller
The IBM 81Y4494 ServerRAID H1110 functions primarily as a Host Bus Adapter (HBA), providing direct connectivity to SAS and SATA storage devices. It typically operates in a "JBOD" (Just a Bunch Of Disks) mode, allowing the operating system to manage individual drives or implement software RAID.
1. Drive Detection
Upon successful driver installation and system boot, connected SAS/SATA drives should be detected by the operating system. You can verify this through the operating system's disk management utilities.

2. Storage Configuration
For advanced storage configurations, such as software RAID (e.g., RAID 0, RAID 1, RAID 5, RAID 10), use the tools provided by your operating system (e.g., Windows Storage Spaces, Linux mdadm) or third-party software solutions. The H1110 provides the physical interface; the operating system handles the logical volume management.
3. Monitoring
Monitor the health and status of your connected drives using the operating system's built-in tools or specialized monitoring software. Some operating systems may provide basic information about the HBA itself.
