The new XServer has been rebuilt to tackle the most rigorous server task at maximum speed. It's outstanding performance starts with the Quad-Core Intel Xeon 5400 series processors. XServer comes fully equipped for deployments in demanding businesses and institutions. An unlimited-client license for Mac OS XServer—integrating a host of powerful network services and intuitive management and monitoring tools—adds unparalleled value at no extra cost. For increased uptime, robust hardware features like ECC memory and lights-out management are standard on all systems, with dual power supplies and hardware RAID available as configureto-order options.

Xserve with Mac OS X Server is ideal for traditional server applications, including cross-platform file and print, managing Mac desktops in workgroups or classrooms, web and application serving, and media streaming. Innovative new communication tools in Leopard Server—such as group calendaring, wiki-based collaboration, and a media workflow engine called Podcast Producer—give workgroups the power to interact like never before. And with 8-core processing and a 64-bit operating system, Xserve has the horsepower for compute-intensive environments, such as rendering farms and computational clusters.

Next Generation Intel Processor	Greener, more efficient design	Flexible storage options	Unlimited-client license for Mac OS X Server
Featuring the Quad-Core Intel Xeon "Nathalem" processor and an integrated memory controller, the new Xserve boosts performance up to 2x.	Designed with the environment in mind, the new XServe delivers 89 percent better performance per watt and eliminates many toxins such as PVC and BFRs.	An ultra-efficient 128GB solid-state boot drive option, up to 6TB of internal storage, and RAID 5 support give the new Xserve industry-leading storage capability.	Xserve provides everything you need to serve Mac, Windows and Linux clients, right out the box. No more paying extra for client licences.

Key Features

Quad-Core Intel Xeon processors

Xserve incorporates Quad-Core Intel Xeon 5400 series “Harpertown” processors with a 1600MHz frontside bus for a massive processing gain. Each 64-bit Xeon processor, built using an advanced 45-nanometer production process for reduced die size and power consumption, has 12MB of shared L2 cache, enhanced floating-point units, and 128-bit SSE4 vector engines.

New system architecture

Featuring two independent frontside buses running at 1600MHz, providing up to 25.6GB/s of throughput to the rest of the system, and 800MHz DDR2 ErrorCorrection Code (ECC) memory, the new system architecture in Xserve is ideally matched to feed the fast Quad-Core Intel Xeon processors with data. The advanced 256-bit-wide memory controller uses four FB-DIMM (fully buffered DIMM) channels to provide up to 32GB of capacity while providing a 64 percent improvement in memory bandwidth over the previous generation.

PCI Express 2.0 expansion

To deliver exceptional server performance, Xserve provides enhanced I/O bandwidth to match the increase in processing performance.
Two PCI Express 2.0 expansion slots—one 16-lane, one eight-lane—provide up to 8GB/s of throughput to support the latest Apple and third-party high-bandwidth I/O cards, including dual- and quad-port 4Gb Fibre Channel and 10Gb Ethernet networking.

Flexible advanced storage

With three drive bays, Xserve provides up to 3TB of internal storage capacity through an advanced storage controller that supports SATA (Serial ATA) and SAS (Serial Attached SCSI) drives.1 Enterprise-class SAS hard drives deliver phenomenal performance—up to 125MB/s with seek times as low as 3.5 ms— and are ideal for demanding applications.4 An optional Xserve RAID card provides internal hardware RAID 0, 1, and 5 with 256MB of cache plus a 72-hour cache battery backup for advanced data protection.

Built-in lights-out management

As long as the electrical power cord and Ethernet cable are plugged in, built-in remote management capabilities allow control of an
Xserve system from anywhere on the network—even if the system isn’t turned on. Easy-to-use Server Monitor software provides remote monitoring and control of
Xserve with an intuitive graphical interface.

Efficiency 

Xserve is built around cutting-edge 45-nm process technology, so it packs even more power but consumes even less. Running at a maximum 80W per socket across all speeds, Xserve achieves up to twice the performance per watt. With enhanced idle power, processor power consumption drops as low as 4W. An intelligent thermal control system tracks more than a dozen sensors and manages the speed of each fan, optimally cooling the entire system and reducing power noise.
