After its initial launch several years ago, sales of Apple's Xserve rack server line struggled. Throughout each quarter of 2003, Xserve sales averaged in the 5,000 to 6,000 unit range. Then, in first-quarter, 2004, sales slumped to a low of 4,412. Apple responded with a timely revamp followed by a drop in price to a little more than $2,000. Result: Sales have more than doubled, according to Gartner's quarterly survey numbers.
"Clearly, the core audience for the Apple Xserve is among existing Mac users," said John Enck, an analyst at Gartner. "It plays well in any environment that has a good deal of heterogeneity in the client and server environment."

The March 2004 version introduced the Mac OS 10.3 (code named Panther) and a 64-bit IBM G5 processor. This latest iteration has further strengthened that foundation with more RAM and greater storage space. As a result, Xserve is gaining traction in markets looking for high performance and a low footprint.
In the scientific community, for example, Virginia Tech clustered 1,100 Xserve servers to form a supercomputing platform that ranked number 7 in the latest Top500 Supercomputing Sites survey. Another adopter, government contractor Colsa, combined 1,556 Xserve units for hypersonic flight simulation.
"We have seen significant growth in science, education, SMB and the creative arena," said Alex Grossman, director of hardware product marketing at Apple. "Many of these users are looking for high-performance computing."
In the case of Xserve, that performance comes with up to 8 GB of RAM, a 1 GHz front side bus, and a 2 GHz 64-bit processor. While Intel is planning to move Itanium to 90 nanometers some time next year, IBM is already there with the G5, the processor used in XServe.
Xserve's allure is further heightened by a complementary RAID box that adds as much as 5.6 TB in a 3U space, up from 3.5 TB in the March release. That works out to about $2 per GB. Apple also recently added a new hardware RAID card to supplement the RAID software built into Panther to enhance storage performance.
Each Xserve RAID box has three hard drives and can be arranged in RAID 0, 2, 3, 5, 10 as well as more exotic configurations, like RAID 30 and 51. RAID 5 delivers 800 GB of space, and RAID 0 offers 1.2 TB per unit.
"A lot of customers don't need the extra RAID box, as the Xserve alone gives them all the storage they need," said Grossman. "When it comes to tier-two storage, its hard to beat Xserve RAID for cost effectiveness."
The storage box is Fibre Channel based to the host, and much of the traditional Fibre Channel complexity is masked from the user, according to Grossman.
