Dell HBA355i Front Non-RAID Host Bus Adapter

The Dell HBA355i (DPN 07GRF6) is a modern, enterprise-grade PCIe Gen4 x8 host bus adapter designed to deliver high-performance, low-latency direct-attached storage connectivity in Dell PowerEdge environments. Built for data-intensive workloads, it provides a pure HBA (non-RAID) architecture that exposes drives directly to the operating system, making it ideal for software-defined storage platforms such as VMware vSAN, Linux ZFS, Ceph, and Windows Storage Spaces. By removing RAID overhead entirely, it ensures maximum transparency, flexibility, and predictable performance across large storage arrays.

Engineered to support up to 16 internal SAS/SATA devices, the HBA355i delivers 12Gb/s SAS and 6Gb/s SATA connectivity per drive, leveraging a PCIe Gen4 x8 host interface to ensure ample upstream bandwidth for modern storage workloads. It is fully optimised for mixed-drive environments, supporting both enterprise SAS SSDs/HDDs and SATA drives, while maintaining consistent throughput across multi-drive configurations and SAS expander-based architectures. This makes it a strong choice for high-density storage deployments where scalability and direct disk access are critical.

Designed for integration within the latest Dell infrastructure, the HBA355i is compatible with a wide range of Dell PowerEdge server. Its low-profile form factor and Dell-validated firmware ensure seamless installation, system management via iDRAC, and full platform support within Dell’s storage ecosystem. Ideal for enterprise storage builds prioritising performance, scalability, and software-defined control, the HBA355i provides a robust and future-ready foundation for modern server storage architectures.
