IBM X3850 X6 User Manual

Chapter 3. Product information 85
The PCIe lanes used in the I/O Books and Storage Book are connected to installed
processors as follows:
򐂰 The slots in the Primary I/O Book and Storage I/O Book connect either to processor 1 or
processor 2.
򐂰 The slots in the Optional I/O Book in bay 1 connect to processor 4.
򐂰 The slots in the Optional I/O Book in bay 2 connect to processor 3.
This PCIe connectivity is shown in Figure 3-23.

3.12 Primary I/O Book
The Primary I/O Book is the core module, which provides base I/O connectivity, with four
PCIe slots:
򐂰 Two PCIe 3.0 x16 slots (x16-wired), half-length, full-height, up to 75W of power
򐂰 One PCIe 3.0 x16 (x8-wired), half-length, full-height, up to 75W of power
򐂰 One Mezzanine LOM Generation 2 (ML2) slot for network adapters with the new ML2 form
factor (PCIe 3.0 x8)
As shown in Figure 3-23, the use of all slots in the Primary I/O Book requires two processors
(two Compute Books) installed:
򐂰 Processor 1 drives a PCIe x16 slot and the ML2 slot
򐂰 Processor 2 drives the other PCIe 16 slot and the PCI x8 slot
