IBM eX5 Implementation Guide

Chapter 3. IBM System x3850 X5 and x3950 X5 61

Figure 3-5 MAX5 connectors and LEDs

Figure 3-6 shows the internals of the MAX5 including the IBM EXA chip, which acts as the

interface to the QPI links from the x3850 X5.

Figure 3-6 MAX5 memory expansion unit internals

For an in-depth look at the MAX5 offering, see 3.5, “MAX5” on page 68.

3.1.4 Comparing the x3850 X5 to the x3850 M2

Table 3-1 on page 62 shows a high-level comparison between the eX4-based x3850 M2 and

the eX5-based x3850 X5.
