HP increased its server share to 25.4 percent in Q2 2015 from 25.1 percent in Q1 2015.
Dell share marginally decreased to 17.5 percent from 17.6 percent.
Cisco increased its server market share to 6.4 percent from 5.7 percent, according to IDC Worldwide Quarterly Server Tracker.
IDC said the server market increased 6.1 percent to $13.5 billion in the second quarter of 2015 with revenue growing in rack-optimized, blade, and density-optimized form factors, while towers declining slightly.
Server shipments increased 3.2 percent to 2.29 million units.
Volume system revenue increased 8.1 percent to $10.1 billion supported by expansion of x86-based hyper-scale server infrastructures coupled with enterprise and SMB refresh of x86-based platforms.
High-end system demand increased 4 percent to $2.3 billion helped by IBM’s z13 refresh.
Demand for midrange systems fell 5.4 percent to $1.1 billion.
“The growth in the server market is confirmation of the larger IT investment taking place, despite dramatic change occurring in system software thanks to open source projects such as Docker and OpenStack,” said Al Gillen, program vice president, Servers and System Software at IDC.
HP achieved 7.7 percent increase in revenue to $3.4 billion driven primarily by strong demand for its density-optimized servers, which grew 118.7 percent, and its rack-optimized servers, which rose at 10.5 percent.
Dell generated $2.4 billion revenue from servers with a growth of 5.9 percent – fuelled by growth in its blade and rack-optimized products. Dell’s blade server revenue grew 38.7 percent, discounting Lenovo’s acquisition of IBM’s x86 server business.
IBM retained its number 3 position following the divestment of its x86 with $2 billion in revenue and 14.8 percent market share. IBM’s revenues are associated with its POWER and System Z product lines.
Cisco’s 19.3 percent growth was above average for the industry. Cisco’s blade business revenue is second only to HP.
