Sun SPARC Enterprise T5120 and T5220
Server Architecture
Sun SPARC Enterprise T5120 and T5220 servers have been designed to provide
breakthrough performance while maximizing reliability and minimizing power
consumption and complexity. This section details the physical and architectural aspects
of these systems.
System-Level Architecture
A unified motherboard design is common to both the Sun SPARC Enterprise T5120 and
T5220 servers (Figure 9). The motherboard is a 20-layer printed circuit board (PCB)
containing the UltraSPARC T2 processor, FBDIMM sockets for main memory, ILOM
service processor, disk controller, and I/O subsystems. I/O options include USB, DVD
control, quad Gigabit Ethernet, and two levels of PLX PCI Express branching out into
sockets for a wide variety of third-party PCI Express expansion options. Shaded regions
indicate features that are only available on the Sun SPARC Enterprise T5220 server.
