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
http://www.lsi.com/ . The 1078 SAS ROC
provides this functionality:
ƒ PCI Express* interface (x8), 2.5 Gbps
ƒ Local 72-bit DDR2 SDRAM interface with ECC checking
ƒ 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.
ƒ Two messaging units. Only one can be enabled per power-on cycle:
- Fusion MPT message unit
-
Proprietary / test message unit
ƒ Two I 2 C interfaces for memory detection and PCI Express* SMBus connectivity. Serial
boot-strap ROM is also connected here.
ƒ Integrated dual UART for MegaRAID* diagnostic use only.
ƒ Eight channels of 3 Gbps full duplex SAS / SATA / Tunneled SATA
ƒ Two banks of SGPIO signals to accompany the two sets of x4 SAS/SATA ports
ƒ PCI Express* interface supports x8, x4, and x1 lane configurations
