Intel® E7501 (Plumas 533) MCH. The E7501 Memory Controller Hub (MCH) processor interface supports the System Bus Protocol at peak bandwidth of 3.2 GB/s (400 MHz) or 4.26 GB/s (533 MHz), and is optimized for dual Intel Xeon processors with 512-KB L2 cache. The MCH supports a 144-bit wide channel of Double Data Rate (DDR) DRAM operating in lock-step, and provides Hub Interface 1.5 connection for ICH3-S and Hub Interface 2.0 connection for P64H2 devices.

Intel® P64H2 PCI-X hub. The P64H2 is PCI/PCI-X 64-bit Hub 2 that provides high-performance I/O capability including 16-bit Hub Interface 2.0 connection to MCH, and two independent 64-bit PCI/ PCI-X interfaces.

5604-pin CPU sockets. Two 604-pin surface mount, Zero Insertion Force (ZIF) sockets are onboard for the Intel® Xeon™ processor with 512KB L2 cache and a 400/533 MHz system bus that allows up to 3.2GB/s or 4.26GB/s data transfer rate. These sockets also support Intel Xeon CPUs with Hyper-Threading Technology feature.

8/4-pin 12V SSI power connector. This 8/4-pin connector is for an SSI-type/ATX power supply.

SCSI connector. This dual-channel SCSI connector supports up to 30 devices and data transfers of 320Mbps.

The onboard SCSI connectors are available only on PU-DLS models.

8Adaptec® AIC-7902W SCSI controller. The 7902W SCSI controller is a PCI-Xdual-channel Ultra320 SCSI ASIC compliant to PC 2000-2001. Each channel supports a data transfer rate up to 320 MB/s on a Wide (16-bit) SCSI bus with Low Voltage Differential (LVD) devices. The combined available SCSI throughput is 640 MB/s. In PCI and PCI-X modes, the controller operates as a multifunction 32-bit or 64-bit bus master.

The Adaptec® AIC-7902W SCSI controller is available only on

PU-DLS models.
