“As in the first quarter, the second quarter again demonstrated strong year-on-year growth,” said Jeffrey Hewitt, research VP at Gartner. “There remained some regional variations, but all geographies demonstrated improving market conditions. However, x86-based servers grew 28.9% in units in the second quarter and 37% in revenues; RISC/Itanium Unix servers remained constrained, with declines of 16.5% in shipments and decreases of 8.8% in vendor revenues, compared to the same quarter last year; whilst the ‘other’ CPU category, primarily mainframes, fell 22.8% in revenues for the quarter.

From the regional standpoint, Eastern Europe grew the most significantly in server shipments, with a 46.9% increase in the second quarter of 2010, as well as the highest vendor revenue growth, at 26.2% for the period. All other regions had varying shipment and revenue increases.
