The Intel® Integrated RAID Module SROMBSASMR supports both enterprise-class serial ATA
(SATA) and serial-attached SCSI (SAS) disk drives, which allows solutions to be customized for
performance, reliability, system expansion flexibility, and hard drive capacity. It provides such
flexibility and helps lower the total cost of ownership with a standardized server and storage
infrastructure.
This RAID module is designed with four internal SAS/SATA ports through 4 individual
connectors and uses a custom board-to-board 50-pin connector to provide x4 PCI Express*
support.

The Self Monitoring Analysis and Reporting Technology (SMART) detects up to 70 percent of all predictable disk
drive failures. In addition, SMART monitors the internal performance of all motors, heads, and drive electronics.
The LSI* 1078 SAS ROC is an integrated SAS and I/O controller with an embedded Power PC*
core running at 533 MHz. For information, see
provides this functionality:
PCI Express* interface (x8), 2.5 Gbps
Local 72-bit DDR2 SDRAM interface with ECC checking
Dual independent internal DMA controllers maximize parallel data movement operations
between system memory and any peripheral/block on the processor local bus (PLB),
including local external devices such as Flash ROM, NVRAM, etc.
Two messaging units. Only one can be enabled per power-on cycle:
- Fusion MPT message unit
- Proprietary / test message unit
Two I
2
C interfaces for memory detection and PCI Express* SMBus connectivity. Serial
boot-strap ROM is also connected here.
Integrated dual UART for MegaRAID* diagnostic use only.
Eight channels of 3 Gbps full duplex SAS / SATA / Tunneled SATA
Two banks of SGPIO signals to accompany the two sets of x4 SAS/SATA ports
PCI Express* interface supports x8, x4, and x1 lane configurations
The Intel® Advanced+ Book Block Flash Memory device is a 4 MB FLASH ROM configured for
16-bit I/O, manufactured on Intel’s latest 0.13 μm and 0.18 μm technologies. This is a featurerich solution for low-power applications. This device incorporates low-voltage capability (3 V
read, program, and erase) with high-speed, low-power operation. Flexible block-locking allows
any block to be independently locked or unlocked. For more information, see the Intel
Memory web site at

2.3.3 Boot Strap ROM (SEEPROM)
The serial bootstrap ROM is used to configure the 1078 before the server board configures the
PCI Express* registers. The bootstrap ROM sets the PLL (Phase Lock Loop) dividers, external
memory bus speed, etc.
2.3.4 NVSRAM
A 32-KB NVSRAM stores board and disk drive setup configurations.
2.3.5 SDRAM (Cache)
The Intel® Integrated RAID Module SROMBSASMR includes 128 MB of integrated DDR2 667MHz ECC SDRAM memory. It supports a three chip 40-bit memory configuration. The memory
chips are 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 optional Intel
®
RAID Smart Battery AXXRSBBU3 provides a battery backup option for data
cached in the memory.
