Server revenue worldwide was down 7.7 percent year-over-year in the first quarter, as weak economic conditions and server consolidation by customers slowed sales, according to research firm IDC. Revenue in the market dropped to $10.9 billion in the quarter, the fifth-time in the last six quarters the server industry saw year-over-year decline. Server shipments also fell in the period by 3.9 percent year-over-year.
