PCI/PCI-X IOBP
On the 10 slot PCI/PCI-X IOBP there are a total 8 Public slots (PCI-X mode1/2), 2 Private Fast-core
slots (PCI-X mode1), and 1 Private Slow-core UCIO slot (PCI 32-bit/33-MHz). The eight Public
slots are further subdivided into three speed/bandwidth configurations:
•
Four PDHP (Public Dual Hot-plug), which operate at 64-bit/66-MHz PCI-X
•
Two PSHP-SDR (Public Single Hot-plug - Single Data Rate), operating at 64-bit/133-MHz
PCI-X
•
Two PSHP-DDR (Public Single Hot-plug - Double Data Rate), at 64-bit/266-MHz (133-MHz
double clocked) PCI-X mode2
