• Fan boards provide connections for power and control for both the primary and
secondary fans in the front of the chassis. No cables are required since every dual fan
module plugs directly into one of these PCBs which, in turn, plugs into the Connector
Board.
• PCI Express riser cards plug directly into the motherboard, allowing PCI Express cards
to be installed.
• Two XAUI riser cards provide slots that access to the on-chip 10 Gb Ethernet interfaces
on the UltraSPARC T2 Processor. Alternately, these slots can provide access to PCI
Express interfaces. Each slot can either accept an optical/copper XAUI card, or an
industry standard low-profile PCI Express card with up to an x8 form factor edge
connector (x4 electrically). Cards are installed in a horizontal orientation.
• The disk backplane mounts to the disk cages in the two chassis, delivering disk data
through one or two 4-channel discrete mini-SAS cables from the motherboard. A
4-disk backplane is offered for the Sun SPARC Enterprise T5120 server while the Sun
SPARC Enterprise T5220 server supports an 8-disk backplane.
• A front USB panel card inserts directly into the disk backplane, providing two USB
connections to the front of the system.
Sun SPARC Enterprise T5120 Server Overview
The compact Sun SPARC Enterprise T5120 server provides significant computational
power in a space-efficient low-power 1U rackmount package. With high levels of price/
performance and a low acquisition cost, this server is ideally suited to the delivery of
horizontally-scaled transaction and Web services, and can function as a very capable
HPC compute node. The server is designed to address the challenges of modern
datacenters with greatly reduced power consumption and a small physical footprint.
Depending on the model selected, the Sun SPARC Enterprise T5120 server features a
single four-, six-, or eight-core UltraSPARC T2 processor.
Enclosure
The 1U Sun SPARC Enterprise T5120 server enclosure is designed for use in a standard
19-inch rack (Table 3).
