20. SMBus Connector (6-1 pin SMB)
This connector supports SMBus (System Management Bus) devices. SMBus
devices communicate by means of the SMBus with an SMBus host and/or
other SMBus devices. SMBus is a multi-device bus that permits multiple
chips to connect to the same bus and enable each one to act as a master by
initiating data transfer.
21. SATA Serial ATA IDE Connectors (2 x 7-pin PRI_SATA, SEC_SATA)
Two headers support serial ATA IDE HDD devices. Both RAID 0 or 1 is
supported by both serial connectors. Only one HDD may be attached to
each serial ATA IDE connector for RAID 0 or 1. In addition, one HDD may be
connected to the PRI_ATA133 connector along with one HDD to each serial
ATA connector in a RAID 0 array. (See pages 31 and 82 for more information
about RAID setups.)
