A Starting from OpenSPARC

Sun is not the first opening. Recall, IBM 鏃?Zai in 2004 to reduce research cost and Kuo Tai Wei Liao Power Chan Ye Lian, limited Dude opened Power Jiagou technology, and Cheng Li Power.org Laigeizhongdian Huobantigong the Xiang Guan Jiyu Power Processor Architecture and Application of Kai Fa Zhi Chi support.

From this standpoint, IBM seems to go one step ahead, but the Sun OpenSPARC victory in the opening of its more radical, not forcing developers must join the club SPARC.

Indeed, whether IBM or Sun, open RISC processor, hardware and software specifications are not entirely voluntary - who are willing to share with other high-profit business? The reason why IBM and Sun to take such a policy, of course, not to open standards.

The reason for these moves and high-end processor market status are inseparable. In the enterprise computing market, market centers from the mainframe -> RISC SMP-> x86 server trends are obvious, RISC processor R & D companies are also facing growing pressure on R & D - Since the RISC processor SGI fade out R & D Competition After the R & D in the enterprise processor market, the only AMD, IBM, Sun and Intel Competition.

Although IBM and Sun used in the evaluation of all the occasions of the x86 Opteron and Xeon servers, all that they can not become a rival RISC SMP systems. But in fact, with the x86 architecture-based SMP system performance began to grow, RISC server market alone is greater than the grand enterprise would be difficult to reproduce. The x86 SMP system RISC systems is that the performance advantage of nearly fatal, and the cost reduced by at least 50%.

Therefore, reduce the cost, the key to continued RISC SMP system, which Sun and IBM is the biggest reason to make the decision open as open can result in more capacity.
