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.

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.)

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.)
