SAS 9305-16i PCI Express to 12Gb/s SAS Host Bus Adapter User Guide
June 17, 2016 Chapter 1: SAS 9305-16i Host Bus Adapter User Guide
Overview
Chapter 1: SAS 9305-16i Host Bus Adapter User Guide
1.1 Overview
The PCI Express (PCIe)-to-Serial Attached SCSI (SAS) host bus adapter (HBA), referred to as the Avago 12Gb/s SAS HBA,
provides high-performance internal storage connectivity for servers and workstations. The 12Gb/s SAS HBA provides
sixteen lanes of 12Gb/s SAS connectivity and is matched with eight lanes of PCIe 3.0 8Gb/s performance. The
low-profile design of the SAS HBA includes a full-height mounting bracket and a low-profile mounting bracket that
create a universal fit for any server. The 12Gb/s SAS HBA is developed on the Fusion-MPT-based SAS 3216 controller
that integrates the latest enhancements in PCIe 3.0 technology and 12Gb/s SAS technology.

1.3 Functional Descriptions
1.3.1 PCI Express Interface
PCIe is a high-speed standard local bus for point-to-point interfacing of I/O components to the processor and the
memory subsystems in high-end computers and servers.
The 12Gb/s SAS HBA supports eight-lane PCIe performance up to 64Gb/s single direction and 128Gb/s dual direction.
1.3.2 SAS-3 Interface
The SAS 3216 controller chip contains the SATA+SAS functionality for the 12Gb/s SAS HBA with SAS performance of
1200 MB/s per port in each direction.
