The server revenue share of HPE, Dell and Lenovo dipped in Q4 2015, while IBM and Cisco gained, according to Gartner.
Gartner said HPE’s server revenue share fell to 25.2 percent from 27.9 percent.
The server revenue share of Dell declined to 16.7 percent from 17.3 percent.
Lenovo’s server share dropped to 7.5 percent from 7.9 percent.
IBM has increased its server revenue share to 13 percent from 12.8 percent. Enterprise networking maker Cisco also enhanced its server revenue share to 6.1 percent from 5.5 percent.
Server revenue increased 8.2 percent in the fourth quarter of 2015, while shipments grew 9.2 percent.
Server shipments grew 9.9 percent, and server revenue increased 10.1 percent in 2015.
The growth driver for the quarter in terms of absolute value was the Other Vendors category.
Jeffrey Hewitt, research vice president at Gartner, said: “This collection of unspecified vendors that includes original design manufacturers (ODMs), like Quanta and Wistron, contributed over $750 million in revenue and over 170,000 server unit shipments for the period.”
This demonstrates that the growth of hyperscale data centers, like those of Facebook, Google and Microsoft, continues to be the leading contributor to physical server increases globally.
The global mega data center market is expected to exceed $14 billion by 2019 growing at a CAGR of over 7 percent during the forecast period, according to Technavio’s latest report.
Rakesh Panda, a lead analyst at Technavio for data center research, said: “60 percent of the planet will be connected to the Internet by 2020, with a cumulative generation of 40 ZB or more of data, which will be stored and managed through data centers.”
In addition, banking and financial organizations, healthcare, retail, telecommunications, and other industries such as mining and manufacturing operate regional and global data centers.
Gartner says x86 server demand increased in shipments by 9.3 percent and revenue by 10.4 percent for the fourth quarter of 2015.
The outlook for 2016 suggests that modest growth will continue in the server market with some constraint being felt from current economic and currency exchange issues in some regions.
