1.3 Physical package
Table 1-2 lists the physical dimensions of an individual enclosure. Both servers are available
only in a rack-mounted form factor. They are modular systems that can be constructed from
one to four building-block enclosures. Each of these enclosures can take 4U (EIA units) of
rack space. Thus, a two-enclosure system requires 8U, three enclosures require 12U, and
four enclosures require 16U.
