HP and Dell, on the other hand, led in low-end, x86 computers. HP was No. 1 with $2.1 billion in revenues in the quarter, or a 34.3 percent market share, up about 2.5 percent from a year ago. Dell followed with $1.3 billion, or a 22 percent share, followed by IBM with $975.3 million, or 16.2 percent.
Overall revenues from Linux-based servers increased by about 40 percent in the quarter, to $1.5 billion, Gartner said.
"Linux server revenue didn't grow as fast as I though it would, but it's still pretty healthy," McLaughlin said.
Linux has been so successful over the last several years that overall revenue growth would eventually start to slowdown, McLaughlin said.
"I don't think it's going to come to a standstill, but there was so much growth that people are now catching up in terms of its use," the analyst said.
