The Intel
®
Server Board SE7500WV2 is configured with two 64-bit PCI-X riser slots, each of which is connected to
separate fully independent 64-bit PCI-X buses controlled by the P64H2 PCI controller hub. These PCI riser slots are
specifically designed to support either a 1U PCI riser card with a single PCI expansion slot or a 2U PCI riser card with
three PCI expansion slots and provide the following features:
•
PCI segment P64-B:
−
Designed to support a single riser card capable of supporting full-length, full-height PCI cards. This segment
provides support to the onboard network interface controller and to the one or three PCI expansion slots
available on the PCI riser card.
•
PCI segment P64-C:
−
Designed to support a single riser card capable of supporting only low profile PCI cards. This PCI segment
provides support for the onboard SCSI controller (SCSI SKU only) along with the one or three PCI expansion
slots available on the PCI riser cards.
•
Zero channel RAID:
−
The SCSI version of the Intel Server Board SE7500WV2 is capable of supporting a zero channel RAID
controller in the first slot of either the 1-slot or 3-slot PCI riser card used on the P64-C PCI segment. This add-
in card leverages the onboard SCSI controller along with its own built-in intelligence to provide a complete
RAID controller subsystem onboard.
−
With a zero channel RAID card installed in the appropriate PCI expansion slot, SCSI interrupts are routed to the
RAID card instead of to the PCI interrupt controller.
The PCI-X specification supports a 64-bit bus operating at speeds of 66 MHz, 100 MHz or 133 MHz, to provide
throughput speeds of 528 MB/s, 800 MB/s and 1064 MB/s respectively. More than just an improvement in bandwidth,
PCI-X also provides a number of efficiency enhancements and intelligence to the bus to allow better use of the available
bandwidth, support for hot-swap, and full backward compatibility to PCI 2.2. As is the case with PCI 2.2, the PCI-X bus
operates at the frequency of the lowest frequency card connected to the bus.
A PCI-X bus operating at 66 MHz can support up to 4 PCI-X devices. With the addition of PCI-X-to-PCI-X bridge
additional slots can be supported.
A PCI-X bus operating at 100 MHz can support a maximum of two devices.
A PCI-X bus operating at 133 MHz can support only a single device.
