Hi,
The difference between PERC 2/SI and PERC 2/DC is the following one:
Perc 2/SI is an embedded card with a SINGLE channel. You can plug all your disks only on one SCSI channel.
PERC 2/DC is a Additionnal Card with DUAL channels. That means that you can split your hard disk drives beetween two channels. It's interresting for performance with some types of raid like the raid 50. (2xRaid 5 in stripping).
Regards.
Greg.
