Server Board S1200V3RP TPS
Functional Architecture
Revision 1.2

3.4.3.1
AHCI
The Intel
®
C220 series chipset provides hardware support for Advanced Host Controller
Interface (AHCI), a standardized programming interface for SATA host controllers. Platforms
supporting AHCI may take advantage of performance features such as no master/slave
designation for SATA devices
—each device is treated as a master—and hardware assisted
native command queuing. AHCI also provides usability enhancements such as Hot-Plug. AHCI
requires appropriate software support (for example, an AHCI driver) and for some features,
hardware support in the SATA device or additional platform hardware.
The server board includes support for two embedded software RAID options:
Intel
®
Embedded Server RAID Technology 2 (ESRT2) based on LSI* MegaRAID SW
RAID technology
Intel
®
Rapid Storage Technology (RSTe)
Using the <F2> BIOS Setup Utility, accessed during system POST, options are available to
enable/disable SW RAID, and select which embedded software RAID option to use.
3.4.3.2
Intel
®
Rapid Storage Technology enterprise
The Intel
®
C220 series chipset provides support for Intel
®
Rapid Storage Technology enterprise,
providing both AHCI (see above for details on AHCI) and integrated RAID functionality. The
industry-leading RAID capability provides high-performance RAID 0, 1, 5, and 10 functionality
on up to 6 SATA ports of the Intel
®
C220 series chipset. RSTe RAID support is provided to allow
multiple RAID levels to be combined on a single set of hard drives, such as RAID 0 and RAID 1
on two disks. Other RAID features include hot-spare support, SMART alerting, and RAID 0 auto
replace. Software components include an Option ROM for pre-boot configuration and boot
functionality, a Microsoft Windows* compatible driver, and a user interface for configuration and
management of the RAID capability of the Intel
®
C220 series chipset.
3.4.3.3
Intel
®
Embedded Server RAID Technology 2 (ESRT2)
Features of the embedded software RAID option Intel
®
Embedded Server RAID Technology 2
(ESRT2) include the following:
Based on LSI* MegaRAID Software Stack
Software RAID with system providing memory and CPU utilization
Supported RAID Levels
– 0, 1, 10, RAID 5 support provides with upgrade key of
RKSATA4R5.
Open Source Compliance = Binary Driver (includes Partial Source files) or Open Source
using MDRAID layer in Linux*
OS Support = Microsoft Windows 2012*, Microsoft Windows 2008*, RHEL*, SLES, and
other Linux* variants using partial source builds
Utilities = Microsoft Windows* GUI and CLI, Linux* GUI and CLI, DOS CLI, and EFI CLI
3.4.4
Low Pin Count (LPC) Interface
The Intel
®
C220 series chipset implements an LPC Interface as described in the
LPC 1.1
Specification
and provides support for up to two Master/DMI devices. On the server board, the
LPC interface is utilized as an interconnection between the chipset and the Integrated Base
