• Allows multiple initiators to address a single target (in a fail-over configuration) through an expander. For more information, see http://www.lsi.com/. Note: Some of these chip features may not be supported by Intel® Integrated RAID Module RMS2AF040 and RMS2AF080. Flash ROM An 16-MB CFI-compliant flash ROM is used to accommodate RAID firmware and RAID BIOS Console 2 OpROM. Boot Strap ROM (SEEPROM) The serial bootstrap ROM is used to configure the LSI* LSISAS2008 Processor Chip before the server board configures the PCI Express* registers. The bootstrap ROM sets the Phase Lock Loop (PLL) dividers, bootstrap configuration, and so on. NVSRAM A 32-KB NVSRAM is used to store disk and drive setup information. Diagnostic Components LED Placement and Function The Intel® Integrated RAID Module RMS2AF040 and RMS2AF080 contain the following LEDs: • One surface-mounted heartbeat ("DS1B1: SAS_HB_LED") LED (Green Color) to indicate LSISAS2008 activity. • Another surface-mounted system error ("DS1B2: SAS_FLT_LED") LED (Amber Color) to indicate a board error. SAS/SATA Connectors The Intel® Integrated RAID Module RMS2AF040 and RMS2AF080 provides four and eight internal SAS/SATA signal port connectors.

Integrated RAID Module
RMS2AF040 and RMS2AF080.
Flash ROM
An 16-MB CFI-compliant flash ROM is used to accommodate RAID firmware and RAID
BIOS Console 2 OpROM.
Boot Strap ROM (SEEPROM)
The serial bootstrap ROM is used to configure the LSI* LSISAS2008 Processor Chip
before the server board configures the PCI Express* registers. The bootstrap ROM sets
the Phase Lock Loop (PLL) dividers, bootstrap configuration, and so on.
NVSRAM
A 32-KB NVSRAM is used to store disk and drive setup information.
Diagnostic Components
LED Placement and Function
The Intel
®
Integrated RAID Module RMS2AF040 and RMS2AF080 contain the
following LEDs:
•
One surface-mounted heartbeat (“DS1B1: SAS_HB_LED”) LED (Green Color) to
indicate LSISAS2008 activity.
•
Another surface-mounted system error (“DS1B2: SAS_FLT_LED”) LED (Amber
Color) to indicate a board error.
SAS/SATA Connectors
The Intel
®
Integrated RAID Module RMS2AF040 and RMS2AF080 provides four and
eight internal SAS/SATA signal port connectors.
