IDC estimates that the server market has grown to an installed base of over 32 million systems worldwide. This large installed base represents an opportunity for vendors to supply the systems required to replace these systems as they need to be refreshed. The x86 market is the largest and fastest-growing segment of the market. Sun Intel Xeon processor-based systems are targeted directly at the market and offer both Windows and Linux operating systems along with Solaris. Their form factor is on target by being focussed on rack-optimized and blade servers that represent the growth within the x86 market.
