Product Overview
Key Features
Apple’s fifth-generation rackmount server, Xserve combines leading-edge Intel
processors, an advanced server architecture, flexible storage features, and powerful
remote management features with Apple’s legendary ease of use and the server
software features of Mac OS X Server. The following features make Xserve a robust,
versatile server solution for business and institutions everywhere.
Two Dual-Core Intel Xeon processors. Xserve incorporates two Dual-Core Intel Xeon
“Woodcrest” processors for a performance gain of up to five times over the previous-
generation Xserve G5.

Each 64-bit Xeon processor has 4MB of shared L2 cache,
compared with 512K on the PowerPC G5, and an enhanced 128-bit SSE3 vector engine.
Dual point-to-point system buses. Two independent frontside buses running at
1.33GHz provide a wide and fast path to system memory. These channels maximize
processor performance by transferring instructions and data at a combined total
throughput of up to 21.3GB/s.
Advanced memory technology. Xserve uses an advanced 256-bit-wide memory
controller that uses four channels of 667MHz DDR2 fully buffered DIMMs (FB-DIMMs)
with Error Correction Code (ECC) protection. This state-of-the-art memory subsystem
provides up to three times the bandwidth of Xserve G5 and twice the capacity—up
to 32GB. It also supports simultaneous reads and writes through the memory
controller and other advanced high-availability features.
High-bandwidth server architecture. To deliver exceptional server performance,
Xserve provides enhanced memory bandwidth, storage bandwidth, and I/O bandwidth
to match the increase in processing performance. PCI Express on the logic board con-
nects all key subsystems. It powers two 8-lane expansion slots, providing four times
the I/O bandwidth of Xserve G5, and supports the latest high-bandwidth I/O cards,
including Fibre Channel, graphics, and networking. Onboard I/O features also include
dual Gigabit Ethernet ports, two FireWire 800 ports, a USB 2.0 port, and a serial port.
Flexible advanced storage. With three drive bays, Xserve provides an advanced 3Gb/s
storage controller that supports both SATA (Serial ATA) and SAS (Serial Attached SCSI)
internal storage capabilities. SATA drives provide outstanding value and excellent
performance while delivering industry-leading capacity—up to 2.25TB using 750GB
hard drives. Enterprise-class SAS hard drives deliver phenomenal performance—up to
126MB/s with seek times as low as 3.5 ms—and are ideal for demanding applications.

In addition, optional PCI Express cards allow connection to external storage devices,
including Apple’s Xserve RAID storage system.
