Technical Product Specification

Hardware IntelP®P RAID Controller RS2PI008 Technical Product Specification

2.3.2 Flash ROM

An 8-MB CFI-compliant flash ROM is used to accommodate RAID firmware and RAID BIOS

Console 2 OpROM.

2.3.3 Boot Strap ROM (SEEPROM)

The serial bootstrap ROM is used to configure the LSI*SAS2108 ROC before the server board

configures the PCI Express* registers. The bootstrap ROM sets the Phase Lock Loop (PLL)

dividers, bootstrap configuration, and so on.

2.3.4 NVSRAM

A 32-KB NVSRAM is used to store disk and drive setup information.

2.3.5 SDRAM (Cache)

The Intel

RAID Controller RS2PI008 includes 512 MB of integrated DDR2 800 MHz ECC

SDRAM memory. This DIMM is connected directly to the memory controller interface bus of the

ROC and serves as storage for the executable code transferred from the flash. It also serves as

cache during RAID transactions. Cache mode selection takes immediate effect while the server

is online and is available on a per virtual drive basis. The ROC memory controller provides

single-bit ECC error correction with multi-bit detection support.

The Intel

RAID Controller RS2PI008 supports the optional Intel

RAID Smart Battery

AXXRSBBU7 which can be mounted directly to the J6B2 connector on the RAID controller or

connected remotely to the J6B1 connector on the RAID controller through a supplied cable to

provide a battery backup option for data cached in the memory. See Figure 3.

: Only one option can be used at a time. Attempting to install two Smart Batteries may

result in system errors.
