Controller Evaluation Platform Board 12
The Intel
®
IQ31244 PCI-X to Serial ATA Controller Evaluation Platform Board (IQ31244) is an
Intel
®
80321 I/O processor-based design using a PCI-X bridge, four Intel SATA controllers, and
Intel
®
82546EB Dual-Port Gigabit Ethernet Controller.
The main application for this customer reference board is external storage. The primary function of
this system is to translate between a disk or network interconnect and SATA. It will also be used to
demonstrate iSCSI and basic NAS functionality.
Figure 27 shows the block diagram of this customer reference board.
