IBM X3850 X6 User Manual

Chapter 2. Technology 21
If you want to take advantage of this recovery, it is important to carefully plan your network
and storage connectivity, because if CPU 1 fails, PCIe slots 9, 10, and 12 become
unavailable.
2.2.2 x3950 X6
The x3950 X6 server has the same architecture adapted to 8-socket configuration.
Figure 2-14 and Figure 2-15 show the system architecture of the x3950 X6 server
(Figure 2-15 shows the upper half, and Figure 2-14 shows the lower half).
