The Xserve (Early 2009) has no frontside bus, and as such there is no published bus speed. In its place, the Mac Pro uses Intel's QuickPath Interconnect system, a bi-directional, point-to-point connection system, which is functionally equivalent to a frontside bus operating at roughly 1:1 with the processor clock speed. An 8-core model with all slots and bays filled weighed 38.3 lbs.

Introduced in April 2009, the Xserve (Early 2009) replaced the Xserve (Early 2008). Though the clock rate of the Xeon 5500-series processor was lower than that of the 5400-series, the system used Intel's Nehalem architecture, which provided more efficient caching and faster, point-to-point connections between the CPU and other system components, which resulted in a generally faster system, particularly for highly multi-threaded applications.

The Xserve (Early 2009) was available in two base configurations, both with 3 GB of RAM and a 160 GB 7200 RPM hard drive. The quad-core model, with a 4-core 2.26 GHz Xeon 5500-series processor, started at $2999. The 8-core model, with two 4-core 2.26 GHz processors, started at $3599. Built-to-order options included dual 4-core 2.66 and 2.93 GHz processors, up to 24 GB of RAM, a 128 GB solid-state drive, up to 3 TB of storage via three hot-swappable bays, a Dual-Channel Gigabit Ethernet PCI Express card, Dual- and Quad-Channel 4 Gb Fibre Channel PCI Express cards, and a second hot-swappable 750W Power supply.
