In the middle of the server, there is a passive midplane that connects all modular components
to each other. Figure 2-6 shows the x3850 X6 midplane:
Figure 2-6 x3850 X6 midplane (front side showing Compute Book connections)
Each Compute Book contains one Intel Xeon processor, 24 memory DIMMs, and two
dual-motor fans. 24 DIMM slots are located on both sides of the Compute Book’s processor
board, 12 memory modules on each side.
Figure 2-7 shows the Compute Book with the clear side cover removed. The front of the
Compute Book are two hot-swap fans.

The x3850 X6 server supports up to four Compute Books; the x3950 X6 server supports up to
8 Compute Books. For more information about the Compute Books, see 3.6, “Compute Book”
on page 64.
