Overview
V-Class Server Architecture
For multiple-cabinet servers, the PCI bus numbering is as shown in
Figure 10. The PCI bus number also serves as the first field of the
associated devices' hardware path, so I/O devices on cabinet ID 0 are
numbered with the first field of the hardware path of 0 to 7.
For cabinet ID 2, the PCI bus numbers are from 64 to 71. PCI busses on
cabinet ID 4 are from 128 to 135, and cabinet ID 6 devices are numbered
from 192 to 199.
The PCI bus and card slot numbering for multiple-cabinet servers is
illustrated in Figure 10 on page 14.
