2.2 Maximum Number of Each Type of Mounted PCI Card and Available PCI Slots
For the maximum number of each type of mounted PCI card and the available PCI slots, see Table 2-1 to Table 2-6 according to the domain OS version.
  1. "Maximum number mounted" means the maximum number of PCI cards that can be mounted in the SPARC M10-4 or PCI expansion unit. The numbers in parentheses indicate the slot numbers where cards can be mounted, among the PCI slots of the SPARC M10-4. If there are no parentheses, all of the slots are available for mounting. In any PCI expansion unit where cards can be mounted, all of the slots are available for mounting.
  2. "2CPU" and "4CPU" under "Maximum number mounted" in the tables refer to the following cases.
    - 2CPU: Configuration with 4 root complexes
    In one case, a CPU memory unit has not been installed.
    In another case, a CPU memory unit has been installed on site, and the I/O bus has not been reconfigured.

    - 4CPU: Configuration with 8 root complexes
    In one case, a CPU memory unit has been ordered together with the server (installed at the factory).
    In another case, a CPU memory unit has been installed on site and the I/O bus has been reconfigured.
  3. The SPARC M10 has an I/O bandwidth of 8 GB/s (simplex) per root complex. The bandwidth between the PCI expansion unit and the SPARC M10 is also 8 GB/s. Therefore, if multiple PCI cards operating at the same time share that bandwidth, each PCI card may not demonstrate the maximum performance. If a high-speed communication card requires a certain level of performance, take the following measures to secure the bandwidth.
    - Mount the card in a PCI slot in the SPARC M10-4 instead of in an PCI expansion unit.

    - Avoid mounting another PCI card in a PCI slot of the same root complex.
