3.1 ServeRAID-MR10i SAS/SATA Controller
The ServeRAID-MR10i SAS/SATA Controller is a dual PHY, SAS
PCI Express adapter and is used in a system with a PCI Express slot
.
PCI Express goes beyond the PCI specification in that it is intended as
a unifying I/O architecture for various systems: desktops, workstations,
mobile, server,
communications, and embedded devices.
The following subsections provide graphics and connector information for
the ServeRAID-MR10i controller.
The ServeRAID-MR10i PCI Express Disk Array Storage Adapter has one
LSISAS1078 ROC (RAID-on-chip) processor that controls eight internal
SAS/SATA ports through two SAS 4x internal connectors.
This subsection provides the board layout and connector information for
the ServeRAID-MR10i controller, which has eight internal SAS/SATA
connectors.
Figure 3.1 displays the connectors on the controller, while
Table 3.1 describes them.
