2.3 Major Components

2.3.1 LSI* 1078 SAS ROC

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

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

2.3.2 Flash ROM

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

http://www.intel.com/design/flash.

Flash

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.
