1-2 Introduction

The PCI Express interface is compliant with the PCI Express

Speciﬁcation, revision 1.0a. All PCI software is backwards compliant with

previous versions of the PCI/PCI-X speciﬁcations. The LSI PCIe to SAS

products implement the PCI Express interface as a x4 or x8 interface.

The LSI PCIe to SAS host adapters use either a standard PCI or a low-

proﬁle PCI bracket type. The LSI PCIe to SAS host adapter SAS

interface is compatible with the ANSI Serial Attached SCSI Speciﬁcation,

revision 1.0 and the Serial ATA Speciﬁcation, revision 1.0a.

The functionality of LSI PCIe to SAS host adapters come from either the

LSISAS1064E controller chip or the LSISAS1068E controller chips. The

LSISAS1064E integrates four high-performance SAS/SATA phys and the

LSISAS1068E integrates eight high-performance SAS/SATA phys. The

design of LSI PCIe to SAS host adapters makes it easy to add SAS

interfaces to any computer, workstation, or server with a PCI Express

bus.

Table 1.1 shows the LSI PCIe to SAS controllers and their associated

host adapters that support SAS/SATA devices. All board numbers contain

an “E” after the numeric portion of their name, indicating that they use

the PCI Express bus. Boards without an “L” after the numbers in their

name use a standard PCI bracket type. Boards with an “L” after the

numbers in their name use a low-proﬁle PCI bracket type.
