Figure 36. Architecture Overview

6.4.2.2 x4 PCI Express* Card Edge Interfaces

Two x4 PCI Express* card edges are used to connect the active midplane to the hot-swap

backplane. For details, see Table 28 and Table 29. The use of card edge connectors to the

backplane eliminates all hard drive cabling.

6.4.2.3 LSI LSISAS1078 ROC

The LSI LSISAS1078 ROC supports transfer rates of up to 3 GB/s on each SAS port. It

integrates a high-speed DDR/DDR2 SDRAM interface for Hardware RAID cache. It utilizes a

PCI Express* interface to provide transmission and reception rates of up to 10 GB/s over a

x4 link.

6.4.2.4 Optional Hardware RAID Support

The active midplane supports options to provide full hardware RAID support. Options required

to enable hardware RAID support include an Intel

RAID Activation Key (Product Order Code –

AXXRAKSAS2) and installation of a Mini-DIMM for Intel

RAID Cache support. To protect from

data loss during an unexpected power loss event, an Intel

RAID Smart Battery Backup module

(AXXRSBBU3) is also supported. Hardware RAID levels supported include 0, 1, 5, 10, and 50.
