The final Apple Xserve was the 2009 1U rack server, built around Intel Xeon 5500-series processors and designed for business, education, and creative teams. Macworld’s contemporary review found it faster and more power-efficient than the preceding model, but also identified meaningful drawbacks—including incomplete remote management and limits on memory and video options. Apple later confirmed it would not develop another Xserve and stopped taking orders after January 31, 2011. Today, whether one is worth keeping depends on a specific legacy workload; current resale prices, modern operating-system compatibility, and parts availability are not established by the historical sources below.
What was the final Apple Xserve?
The final generation was announced on April 7, 2009. Apple described it as a 1U rack server based on Intel “Nehalem” Xeon processors, with optional solid-state boot storage and storage configurations advertised at up to 3TB. Its US launch starting price was $2,999, including Mac OS X Server v10.5 Leopard with an unlimited-client license; that was a launch-era price and bundle, not a guide to present-day value. Apple’s launch announcement.
Apple’s technical specifications describe configurations with one 2.26GHz quad-core Xeon 5500-series processor or two quad-core processors at 2.26GHz, 2.66GHz, or 2.93GHz. The system had three hot-plug drive bays, two PCI Express 2.0 x16 slots, dual Gigabit Ethernet, and optional redundant 750W power supplies. Apple’s Xserve technical specifications.
Storage figures depend on the source and configuration
Apple’s April 2009 announcement advertised internal storage up to 3TB. Apple’s technical-specification page separately lists support for up to 6TB using qualified hot-plug drive modules. These are distinct Apple statements from different contexts; the 6TB figure is not a reason to treat every drive configuration as interchangeable or guaranteed to work.

- Please make sure to check part 614-0408 for functionality and compatibility with your equipment.
Memory limits were configuration- and software-dependent
Apple’s specification page describes a physical memory configuration of up to 48GB and notes that Mac OS X Server v10.6 supports up to 96GB. Macworld listed Leopard Server’s inability to use the machine’s full RAM capacity as a drawback in its 2009 review. The operating-system version therefore matters when interpreting memory figures.
How did the 2009 Xserve perform in its contemporary review?
In a review published July 3, 2009, Macworld judged the new Xserve faster and more efficient than its predecessor. The review’s findings are period measurements and observations, not present-day testing or a guarantee of performance for a used machine.

- Power: Macworld reported plug-level measurements showing 25 percent less power at idle and 10 percent less at peak load than the prior model.
- Exhaust temperature: At peak load, Macworld measured exhaust air at 90°F for the new Xserve and 115°F for the previous Harpertown model—a 25°F difference.
- Configuration tested: Apple supplied a dual quad-core 2.26GHz Xeon system with 12GB RAM, a 128GB SSD, three 1TB SATA disks, an optional RAID card, and two power supplies. Macworld gave that review configuration a retail price of $6,249; it was not the base price or a current valuation.
Macworld’s reported exhaust readings are 25°F apart; that subtraction is more precise than the review’s separate prose description of the change as “30 degrees.” Read Macworld’s July 2009 review.

- Lower power consumption and heat output than the preceding generation in Macworld’s measurements.
- A substantial performance improvement over earlier Xserve generations, as assessed in the review.
What the reviewer criticized
- Lights-Out Management was incomplete.
- SAS drives required third-party sourcing, and the review noted no warranty uplift for SAS drives.
- There was no video-card choice.
- Leopard Server could not use the system’s full RAM capacity.
Apple also published SPECpower_ssj2008 results in its launch announcement. Those were Apple-conducted tests of specified preproduction and shipping configurations, so they should not be read as an independent, directly comparable benchmark.

Is an Apple Xserve still worth using?
There is no single answer for every surviving unit. The historical review supports a conclusion about the 2009 model relative to its predecessor at the time; it does not establish present-day reliability, market value, service-part supply, or compatibility with current operating systems. A machine already supporting a required legacy service may have a role, but a new purchase or production deployment calls for checking the exact unit, required software, and replacement-part situation rather than relying on its original specifications.
- Potentially useful: a known, working Xserve kept for a narrow legacy workload where its rackmount form factor and existing software environment are specifically needed.
- Needs careful validation: any deployment dependent on a particular OS version, remote management, storage setup, or replacement drive. Apple’s specification requires qualified drive modules, drives, and Apple-qualified firmware.
- Not established by the historical sources: current secondhand pricing, present inventory, current operating-system support, and current service-parts availability.
What replaced the Xserve?
Apple’s November 2010 transition guide said the company would not develop a future Xserve and would accept orders through January 31, 2011. Apple proposed Mac Pro with Snow Leopard Server for customers needing more performance, storage, and expandability, and Mac mini with Snow Leopard Server for smaller workgroups or single-service workloads. These were Apple’s transition options in 2010, not current server recommendations. Apple’s Xserve transition guide.

- Boost Your System’s Performance: Increase available memory for smoother multitasking, improved responsiveness and better performance when running memory-intensive applications.
- Matched Specifically to Your Machine: OFFTEK selects the correct memory configuration for the computer shown in this listing, removing the uncertainty from choosing a compatible upgrade.
- We Do the Technical Checking for You: There is no need to compare memory speeds, voltages, form factors or other technical details, as the upgrade has been matched to the machine’s supported requirements.
- Extend the Life of Your Computer: Increasing the available memory can help your existing machine remain productive for longer, offering a cost-effective alternative to replacing the complete system.
- Quick and Straightforward Upgrade: Memory is normally simple to install and requires no software installation; shut down and disconnect the machine before fitting and follow the manufacturer’s instructions.
| 2010 transition option | Apple’s stated fit at the time | Important distinction |
|---|---|---|
| Mac Pro with Snow Leopard Server | Customers requiring greater performance, storage, and expandability. | A Mac Pro tower was not equivalent where a high-density 1U rackmount form factor was required. |
| Mac mini with Snow Leopard Server | Smaller workgroups or single-service workloads; Apple’s guide described small businesses and workgroups of up to 50 in its 2010 context. | The “up to 50” audience was period guidance, not a modern capacity recommendation. |
For a surviving Xserve or a replacement decision, compare the actual workload and user count, storage and expansion requirements, rack density and form factor, power and heat constraints, and the required Mac OS X Server services. A tower or desktop replacement may serve the workload while failing the rack-space requirement that led to choosing a 1U server.
Are ordinary SATA drives compatible with Xserve?
Do not assume that a standard SATA drive is guaranteed to work. Apple’s technical specifications call for qualified hot-plug drive modules using Apple-qualified drives and firmware. Apple lists an Xserve 2TB SATA Drive Module, part MC435G/A, as an accessory, but that does not establish that the module is currently available. Verify the part number, condition, and fit for the particular machine before buying. Apple’s technical specifications and accessory information.

When did Apple discontinue Xserve?
In its November 2010 transition guide, Apple wrote, “Apple is transitioning away from Xserve.” The company said it would not develop a future version and would take orders through January 31, 2011. Apple’s transition guide.
