PCIe Slot Description

When you configure PCIe cards for the RH5885 V3, the following is advised:

  • PCIe slots are available only when the corresponding CPU is installed.
  • Configure a PCIe riser card if PCIe slots 5 to 7 are to be used.
  • For a PCIe x16 card, using slot 5 is preferable to achieve maximum bandwidth and optimal performance.
  • For a PCIe x8 card, using slots 1 to 3 are preferable, followed by slot 5 to achieve maximum bandwidth and optimal performance.

Table 2-49 describes the mapping between PCIe slots and CPUs, and the compliant PCIe standards of the RH5885 V3.

Logical Structure

This topic describes the logical structure of the RH5885 V3.

Figure 2-35 shows the logical structure of the RH5885 V3.

The RH5885 V3 supports a maximum of four Intel® Broadwell-EX® E7-4800 v4 or E7-8800 v4 series CPUs, 16 memory channels, and 48 DIMMs. The CPUs interconnect with each other through QuickPath Interconnect (QPI) buses at a speed of up to 9.6 GT/s.

CPUs connect to PCIe riser cards and PCIe slots on the mainboard over PCIe connectors to provide different types of PCIe slots.

A RAID controller card is combined with the hard disk backplane to work as the hard disk interface module, which connects to CPUs over PCIe connectors.

The baseboard management controller (BMC) module contains a BMC chip. It manages the server, including powering on or off the server, obtaining slot IDs, inspecting power supplies, implementing KVM over IP, and providing the black box function.
