Sun Fire X4200 M2 Server
The Sun Fire X4200 M2 measures 2 rack-unit (RU) high (or 3.449 inches/87.6 mm), 17.5 inches (445 mm) wide, and 25.2 inches (640
mm) deep. It is a rack-optimized, x64-based system with a symmetric multiprocessor. Cooling is accomplished with internal fans
which direct airflow from the front to the back of the chassis. I/O ports are located on the rear panel, with an additional two USB on
the front panel. Access to the power connection is at the rear of the server. Hard drives and optical storage are accessible from the
front of the server.
The Sun Fire X4200 M2 server also provides following system architectural features:
• Two AMD Opteron 2200 Series processors with integrated dual-channel DDR2 memory controllers on each CPU to provide
maximum memory capacity and bandwidth scaling delivering up to 32 GB of capacity and 21.4 GB/sec. of aggregated
bandwidth with 2 CPUs populated and 4 GB DIMMs.
• AMD Direct Connect Architecture that directly connects CPU-to-CPU with 2 HyperTransport links, one of which is cache
coherent, and CPU-to-I/O with non-Coherent HyperTransport links delivering 8 GB/sec. aggregate bandwidth per link, , CPU-
to-memory using the integrated DDR2 controller, and CPU cores to each other on the same die in dual-core processors
