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.
