Server unit shipments grew by 10.9% in Q2 2005, the lowest unit growth in more than two years, IDC says. Linux servers posted their 12th consecutive quarter of double-digit growth, with YTY revenue growth of 45.1% and unit shipments up 32.1%. Microsoft Windows servers showed strong growth, as revenues grew 14.3% and unit shipments grew 10.9% YTY. Significantly, quarterly revenue of $4.1 bln for Windows servers represented 33.5% of overall quarterly factory revenue, as customers deploy more fully configured Windows servers for server virtualization initiatives. Unix servers experienced 2.5% revenue growth year over year; however, unit shipments declined 8.7% when compared with Q1 2004. Worldwide Unix revenues of $4.3 bln for the quarter reflect continued IT investment in this server market segment with particular strength in the high-end of the market.
