Shipments for the quarter increased 8.7% from the same period last year to 2.2 million units, Gartner said. Revenues climbed by 2.6% to $13.4 billion.
Growth in the market was driven both in units and revenue by sales of x86 servers, while revenue from RISC-Itanium Unix servers grew by 8%.
"Underlying market dynamics such as growth from emerging markets, coupled with an ongoing demand for increased capacity, are stronger than any inhibitors such as server virtualization," Gartner analyst Errol Rasit said in a statement. "Any implications from financial market instability were not visible in the server market in the third quarter."
Analysts have said that virtualization, which is technology that enables companies to run multiple operating systems in the same machine, could lower demand by boosting hardware consolidation in the data center.
IBM continued to lead the server market in revenue, despite a drop of 8%. IBM's server shipments fell by just under 4%, while the company's overall market share in terms of shipments dropped by just under 2%. Revenue from IBM System p and System x servers rose, while sales of System z and System i servers declined.
