Sun is set to release super-thin "blade" servers in the middle of the year.
Colin Fowles, director of Sun's blade business team, said there will be two types of blade systems on offer.
The first uses Intel chips and the Linux operating system, and the other uses Sun's UltraSparc chips and its Solaris operating system.
Blade servers have a circuit board with memory, a CPU and a hard disk. They are so thin that they can be stacked side by side within a single enclosure and take up much less space.
In 2003, Sun will release a dual-processor model and then more radical "second wave" designs, he said.
Sun's blades are 16 single-processor servers in a cabinet only 5.25 inches thick, Fowles added.
Sun has been beaten to the blade market by competitors including Compaq and Hewlett-Packard.
