Internal Mini-SAS HD Adapter Adaptec HBA 1100-4i

The Adaptec HBA 1100-4i is a low-profile internal Mini-SAS HD adapter that delivers enterprise-class resiliency through the Smart Storage stack. Based on the PM8222 8x12G SmartIOC 2100 SAS/SATA protocol controller, the card supports up to 24 drives in the HBA 1100 family and is compatible with Microsemi HBA, RAID, and expander tools. The adapter is optimized for mixed device environments including SMR HDDs, modern SAS/SATA SSDs and software-defined storage solutions, while offering improved energy efficiency compared with prior generations.

Advantages

The HBA 1100-4i offers reduced power consumption—over 40% savings versus earlier designs—and significant power benefits relative to competing products. It supports SMR-specific command sets (ZAC/ZBC) for cost-efficient warm and cold storage, and delivers high scalability and interoperability with existing Microsemi management tools and drivers. The adapter also provides high throughput and low latency when paired with low-latency SSDs using SmartPQI drivers.

Suitable for

• Enterprise and hyperscale servers requiring internal Mini-SAS HD connectivity
• Warm and cold storage systems using SMR HDDs
• High-performance storage with SAS/SATA SSDs in rack servers
• Software-defined storage platforms (Microsoft Storage Spaces Direct, VMware vSAN, OpenStack Swift/Ceph)

How to use

Install the HBA 1100-4i into an available PCIe slot on a supported server platform and connect internal drives via Mini-SAS HD cables to the adapter ports. Install the SmartPQI host OS drivers provided by the vendor for optimized low-latency SSD performance and load the maxView management tools for unified device and firmware management. Configure the operating system or software-defined storage stack (for example Microsoft Storage Spaces Direct or VMware vSAN) according to the vendor guidelines to expose connected SAS/SATA devices to the host.

Recommendations

Use vendor-supplied drivers and firmware updates to ensure optimal performance and compatibility. For high-performance SSD deployments, prefer the 24-port variant (HBA1100-24i) or ensure sufficient PCIe bandwidth; for warm/cold storage with SMR drives verify ZAC/ZBC command-set support in your stack. Keep the adapter within supported OS and hardware compatibility lists when scaling up to larger device counts.
