Lenovo 440-8I SAS/SATA HBA 4Y37A78601 | RAID Controller, PCIe

Keep storage expansion clean and predictable with the Lenovo 440-8I SAS/SATA HBA, MPN 4Y37A78601. Built for server environments that need direct host-to-drive connectivity, it provides 8 internal SAS/SATA ports over PCIe for attaching multiple drives without adding RAID complexity where it is not required. This adapter is a practical fit for administrators standardizing on JBOD, boot volumes, or software-defined storage stacks that manage redundancy at the OS or application layer. By avoiding unnecessary controller overhead, it helps preserve system resources while maintaining a straightforward path to scale local storage. For infrastructure teams, the value is in control: fewer moving parts, easier troubleshooting, and a storage path that stays transparent to the operating system. In dense server builds, that can simplify deployment and reduce the cost of adding capacity compared with more feature-heavy RAID controllers. If your design calls for direct-attached SAS/SATA storage with dependable Lenovo compatibility, this HBA is built for that role.
