3.1.2 Overall architecture and components
From an architectural point of view, the DS8800 offers continuity with respect to the
fundamental architecture of the predecessor DS8100, DS8300, and DS8700 models. This
ensures that the DS8800 can use a stable and well-proven operating environment, offering
the optimum in availability. The hardware is optimized to provide higher performance,
connectivity, and reliability.
Figure 3-2 and Figure 3-3 show the front and rear view of a DS8800 base frame (model 951)
with two expansion frames (model 95E), which is the current maximum DS8800 system
configuration.
