8.3.2 Multiport Mini-SAS/SATA Connectors
The server board includes two 40-pin high density multiport mini-SAS/SATA connectors. On the
server board, these connectors are labeled as “SCU_0” supporting the chipset embedded SCU
0 controller, and “SCU_1”, supporting the embedded SCU 1 controller. Both connectors can
support up to four SATA or SAS ports each. By default, only the connector labeled “SCU_0” is
enabled and has support for up to four SATA ports capable of transfer rates of up to 3 Gb/s.
The connector labeled “SCU_1” is only enabled when an optional 8-port SAS or SATA Intel
