Broadcom Avago SAS 9305-16e – High‑Performance Storage Controller

The Broadcom Avago SAS 9305-16e is a cutting‑edge SAS (Serial Attached SCSI) host bus adapter designed for enterprise storage environments. With an eight‑channel architecture and a PCIe 3.0 x8 interface, it delivers exceptional throughput while maintaining a low‑profile form factor suitable for dense server deployments.

Key Technical Specifications

• Channel Count: 8 independent SAS channels enabling simultaneous data paths to multiple drives.
• Data Transfer Rate: Up to 12 Gb/s per channel, providing a maximum aggregate bandwidth of 96 Gb/s.
• PCIe Interface: PCIe 3.0 x8 host bus, ensuring ample lane width for high‑speed communication with the system CPU and memory.
• External Connectivity: Four SFF‑8644 (Mini‑SAS HD) ports, each supporting 12 Gb/s SAS links to external storage enclosures.
• Internal Interface: Supports both SAS and SATA devices internally via the eight channels.
• Power Consumption: 13 W during operation, optimized for energy‑efficient data centers.
• MTBF (Mean Time Between Failures): 3,500,000 hours, reflecting robust reliability for mission‑critical workloads.
• Maximum Devices: Up to 1,024 storage devices can be attached across the eight channels.
• Supported RAID Levels: JBOD (Just a Bunch Of Disks) – ideal for environments that require raw block access without software RAID.

Operating System Compatibility

The controller is engineered to work seamlessly across a broad spectrum of operating systems, ensuring flexibility in heterogeneous IT infrastructures:

• Linux Distributions: Red Hat, SuSE, Debian, CentOS, and generic Linux kernels.
• Windows Platforms: All supported Microsoft Windows server editions.
• Other Unix‑like Systems: FreeBSD, Solaris 8, Solaris 9.
