Sun Microsystems T5220 manual Sun SPARC Enterprise T5120 Server Overview, Enclosure

21 Sun SPARC Enterprise T5120 and T5220 Server Architecture Sun Microsystems, Inc.

•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).
