"The server market was driven by increases in spending by hyperscale as well as enterprise and midsize data centers. Enterprises and midsize businesses are in the process of investing in their on-premises and colocation infrastructure to support server replacements and growth requirements even as they continue to invest in public cloud solutions," said Jeffrey Hewitt, research vice president at Gartner. "Additionally, when it came to server average selling prices (ASP) increases for the quarter, one driver was the fact that DRAM prices increased due to constrained supplies."
