The Origin 3900 server supports a wide range of system configurations to serve your
computing needs (see Table 2-1). The Origin 3900 server scales in 4-processor increments
and in two Cx-brick increments. (The Cx-bricks do not have to be fully populated with
processors.) The Origin 3900 server also supports a memory-only Cx-brick that enables
you to increase the amount of memory without increasing the number of processors.
