1 Overview
The LSI
®
PCI Express
®
(PCIe
®
)-to-Serial Attached SCSI (SAS) host bus adapter (HBA), referred to as the LSI 12Gb/s SAS
HBA, provides high-performance internal storage connectivity for servers and workstations. The LSI 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
LSI 12Gb/s SAS HBA is based on the Fusion-MPT™-architected LSI SAS 3008 controller that integrates the latest
enhancements in PCIe 3.0 technology and 12Gb/s SAS technology.
2 Features

3 Functional Descriptions
3.1 PCI Express Interface
The LSI SAS 9300-16i HBA uses two LSI SAS 3008 controller chips and one PCI Express switch to provide
high-bandwidth interconnection ability. 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 LSI 12Gb/s SAS HBA supports eight-lane PCIe performance up to 64Gb/s single direction and 128Gb/s
dual direction.
3.2 SAS-3 Interface
The LSI SAS 3008 controller chip contains the SATA+SAS functionality for the LSI 12Gb/s SAS HBA. The following table
shows the LSI SAS 12Gb/s SAS performance.
