SAN FRANCISCO Sun Microsystems Inc. says it will cut up to 6,000 of its workers, or 18 percent of its global staff.
Sun also says its software chief, Rich Green, has resigned.
The company has fallen into a deep slump as sales of its high-end servers have collapsed.
The Santa Clara, Calif.-based company said Friday the job cuts will include between 5,000 and 6,000 employees over the next year.
It says the cuts will save $700 million to $800 million annually.
