The demand for customized servers is growing as buying trends change, with more companies designing servers in-house instead of buying from well-established vendors such as Hewlett-Packard or Dell.
Server market revenue in the fourth quarter last year was $14.2 billion, dropping by 4.4 percent compared to the same quarter in 2012, according to a survey released by IDC. The survey showed that sales from smaller white-box server makers -- called "ODM Direct" by IDC -- collectively growing at the fastest rate of 47.2 percent year over year.

The group of white-box server makers includes Quanta and Inventec, which make servers for companies such as Google, Facebook, and Amazon, which have mega data centers and deploy servers by the thousands. Those companies design servers in-house, which are designed to handle the growing flow of search and social networking requests.
The custom servers are also being plugged into hyperscale environments, where servers can be easily added to meet growing computing demands. Hyperscale environments are also being used for a growing number of public and private cloud deployments, which need to be flexible on computing and storage requirements.
The custom servers direct from white-box system makers are also attractive as they are less expensive, IDC said in a statement.
The growth of home-grown servers is hurting the top three server makers IBM, Hewlett-Packard, and Dell, who sell servers based on proprietary designs and system management technologies. The top spot was shared by HP, whose server revenue grew by 5.7 percent and IBM, whose server revenue dropped by 28.5 percent. In third place was Dell, whose server revenue dropped by 2.4 percent in the quarter. One exception was Cisco, whose server revenue went up by 34.5 percent. Oracle, sharing the fourth place with Cisco, recorded a drop of 2.2 percent.
Most custom servers use x86 chips from Intel or Advanced Micro Devices. Revenue for x86 servers was $10.7 billion worldwide, growing by 7.8 percent. Unit shipments of x86 servers during the fourth quarter was 2.5 million units, growing by 8.6 percent.
The Unix server market took a hit with the growth in x86 server sales, IDC said in a statement. Growth in the hyperscale server segment is hurting the growth of servers with proprietary chips like IBM's Power, Oracle's Sparc, and Intel's Itanium. Intel this month introduced the new Xeon E7 v2 x86 chip, which is expected to push Itanium close to its end of life, analysts have said.
The customized server market is receiving a boost from the Open Compute Project, which is making reference designs for servers, data centers, networking, and storage equipment. Many companies, including financial organizations like Goldman Sachs, are warming to OCP server designs, which reduce the reliance on proprietary server designs. Intel, Advanced Micro Devices, and others are making chips, motherboards, and components that fit into these barebones servers. One specification called Group Hug will make it possible to put x86 and ARM chips in the same socket.
HP and Dell continue to introduce new servers, but are also making an effort to fit into the custom server market. Dell is refocusing the efforts of its Data Center Solutions (DCS) to build custom servers. But IBM is heading out of the x86 server market as in January it agreed to sell its x86 server business to Lenovo for $2.3 billion.
