Gartner figures show that users worldwide are investing in both 32-bit and 64-bit servers, with purchases rising sharply between the third quarters of 2004 and 2005.
The three major suppliers, Hewlett-Packard, Dell and IBM saw sales rise, and 28% of x86 servers in use now come from HP, said Gartner.
As for Risc and Itanium Unix servers, organisations bought the largest number from Sun, followed by IBM and then HP.
Windows and Linux-based servers and server blades all saw stronger adoption over the past year, according to analyst firm IDC, but the number of Unix servers shipped declined overall in Q3 2005, compared with Q3 2004, said IDC.
