Intel® Server Board SE7505VB2 PCI I/O Subsystem 5.1.2.2 P64-B Arbitration P64-B supports three PCI masters: two PCI-X slots and the P64H2. All PCI masters must arbitrate for PCI access using resources supplied by the P64H2. The host bridge PCI interface (P64H2) arbitration lines REQx* and GNTx* are a special case in that they are internal to the host bridge. The following table defines the arbitration connections.

All PCI masters must arbitrate for PCI access, using resources supplied by the P64H2. The host bridge PCI interface (P64H2) arbitration lines REQx* and GNTx* are a special case in that they are internal to the host bridge. The following table defines the arbitration connections.

The Silicon Image 3112A provides a single 32-bit / 33-MHz PCI bus master interface as a multifunction device, packaged in a 128-pin PQFP. It supports two modes: base mode and RAID mode. The Silicon Image 3112A controller supports the following features: Automatically selects highest available transfer speed for all devices Supports: - UDMA up to 150MB/second - All UDMA and PIO modes - Up to two SATA devices - ACPI and ATA/ATAPI6 RAID 0 and 11 On-line mirror rebuilding RAID set accommodates multiple size HDDs HDDs function normally when not in RAID sets Adjustable stripe size for RAID 0 1 RAID functionality available under most operating systems.
