The CR-brick contains the processors (8 processors per CR-brick) and two internal
high-speed routers. The routers connect to other system bricks via NUMAlink cables and
expand the compute or memory capacity of the Altix 3700 Bx2. The 40U rack in this
server houses all bricks, drives, and other components; up to a 64-processor
configuration in a single rack. The Altix 3700 Bx2 server system can expand up to 512
Intel Itanium 2 processors, (a minimum of one IX-brick is required for every 256
processors).
The system requires a minimum of one 40U tall rack with at least one power bay and one
single-phase PDU per rack. (The single-phase PDU has two openings with three cables
that extend from each opening to connect to the power bay. The three-phase PDU has two
openings with six cables that extend from each opening to connect to two power bays.)
You can also add additional racks containing CR-bricks, I/O bricks, and disk storage to
your server system.
Figure 3-2 shows an example configuration of a 64-processor Altix 3700 Bx2 server.
