What you will get is performance rivalling much bigger iron. No matter how you stack it up, Xserve G5 knocks out the competition in everything from pure processing power to I/O throughput. For example, the Xserve G5's two double-precision floating-point units let it perform linear equations in LINPACK 8 percent faster than 3.2GHz Xeon-based servers and 50 percent faster than the 2GHz Opteron-based server. The machine simply blasts past others in its class that cost almost twice as much.
Power Comes Standard
Designed to deliver the UNIX-based strengths and cutting-edge capabilities of Mac OS X Server, this rack-optimized server offers phenomenal processing power, massive storage capacity — up to 750GB — and remote management tools that make it a snap to deploy and maintain. Add Xserve RAID, which holds up to 3.5 terabytes of data, and you’ll see why Xserve received the highest marks from Infoworld magazine for all of 2003.
 Rack Them Up
At just 1.75 inches thick, the Xserve 1U form factor enables you to deploy a formidable array of up to 84 G5 processors in a 42U rack that makes the best possible use of the floor space in your server room or data center. The server units have been designed to fit industry-standard four-post and telco racks, and come complete with all the required mounting hardware — as well as the air ducts needed to efficiently cool the system.
Heavy Metal
The Xserve cluster node configuration is ideal for High Performance Computing (HPC) in scientific and technical environments, as well as for workgroup clusters and render farms. The G5 processor’s superscalar, superpipelined architecture supports up to 215 simultaneous in-flight instructions with a high-bandwidth execution core offering over 12 discrete functional units, including dual floating-point units and dual integer units, to process immense instructions in parallel — and of course, with 64-bit precision on 64-bit wide data paths. And by subtracting the components better suited to server tasks, Xserve cluster node delivers the lowest price per gigaflop in the industry.
Innovation Comes Standard
Each Xserve model features dual FireWire 800 ports, one FireWire 400 port, two USB 2.0 ports, an industry standard DB-9 serial port. You can expand the system using the latest 133MHz PCI-X expansion protocol with throughput of 1GBps. Add one full-length card running at 133MHz or 2 short form running at 100MHz. Blinking LEDs show you at a glance how your system is running. But when you’re down the hall or halfway around the planet, Xserve’s critically acclaimed monitoring and management tools let you keep your finger on the pulse of your network.
Robust Server OS Without Per-User “Taxes”
Xserve G5 comes with Mac OS X Server, the UNIX-based server operating system that gives you a complete suite of standards-based network services. You can serve thousands of users — without spending thousands of additional dollars in licensing fees.* Whether you have Mac, Windows, UNIX or Linux clients — or a combination thereof — Mac OS X Server provides cross-platform support for native file sharing, as well as Apache web server and WebDAV server, POP and IMAP mail, ftp, QuickTime Streaming Server, DNS and DHCP — right out of the box. Windows, UNIX and Linux are not treated any differently, and will enjoy benefits that Mac users take for granted.**
