Sun's Solaris annual support contracts range from $240 to $1,180 for one- or two-socket x86 servers, depending on whether the buyer chooses the "basic" or "premium" plan. Sun's basic plan costs about 40 percent less and the premium plan about 50 percent less than comparable Red Hat plans, said Sun spokesman Bob Wientzen.
Red Hat's Web site lists Red Hat Linux ES basic for $349 per year per system and Red Hat Linux AS premium for $2,499. A Red Hat spokesman did not return calls and an e-mail requesting comment, but after Oracle's move last fall, Red Hat chief executive officer Matthew Szulik said Red Hat would not lower its prices due to a competitor's price cuts.
