2.3.1 Introducing the Windows Server 2003 Drivers
Windows Server 2003 runs on Intel architecture (32-bit), Itanium
Processor Family (IA-64), and Extended-64 (AMD64/EM64T) processors.
A Windows application uses the SCSI pass-thru facility to pass SCSI
commands directly to the parallel SCSI, Fibre Channel, or SAS Protocol
devices. This facility allows applications to directly control and access
devices by filling in a data structure and calling into the port or class
driver. Windows Server 2003 provides class drivers for hard disk drives,
optical drives, CD-ROM drives, printers, and scanners. Other class
drivers, provided by peripheral manufacturers, may be added to support
new devices. (Tape device support is built into the operating system itself
and does not require a class driver.)
Microsoft provides the port driver and LSI provides the LSI_SCSI.SYS ,
LSI_FC.SYS , and LSI_SAS.SYS miniport drivers. These drivers complete
the path to the LSI controller or processor with an optional U320 SCSI,
Fibre Channel, or SAS BIOS. The
LSI_SCSI.SYS , LSI_FC.SYS and
LSI_SAS.SYS drivers meet the Microsoft specification for miniport drivers.
These drivers allow connection of parallel SCSI, Fibre Channel, and SAS
devices including disk drives, CD-ROM drives, and tape drives for PCI
and PCI-X based systems. The drivers support all Windows Server 2003
Service Packs.
The LSI miniport drivers use the Microsoft StorPort port driver (instead
of the Microsoft ScsiPort driver used in earlier versions of Windows). The
StorPort driver has architectural enhancements that provide performance
improvements on large server systems with many storage adapters. The
miniport drivers are designed to take advantage of these enhancements
for improved performance.
2.3.2 Driver Features and LSI Device Support
The LSI_SCSI.SYS , LSI_FC.SYS , and LSI_SAS.SYS miniport drivers
support the following:
•
320 Mbytes/s parallel SCSI transfers for LSI53C1020 and
LSI53C1030 controllers using the
LSI_SCSI.SYS driver
•
1 Gbyte, 2 Gbyte, and 4 Gbyte Fibre Channel transfers for
LSIFC949X, LSIFC939X, LSIFC929X, LSIFC919X, LSIFC929, and
LSIFC919 controllers using the
LSI_FC.SYS driver
