Figure 11-6 Standard PowerPC processor complexes for DS6800-511
The next figure, Figure 11-7, provides a less abstract view. It outlines some details on the
dual processor complex of the DS6800 enclosure and its gates to host servers through HAs,
and its connections to the disk storage backend through the DAs.

The DS6800 controls, through its two processor complexes, not only one I/O enclosure as
Figure 11-7 displays, but can connect to up to 7 expansion enclosures. Figure 11-8 on
page 229 shows a DS6800 with one DS6000 expansion enclosure.
