The Sun SPARC Enterprise® M-Series server product family offers a scalable range of compute power, from rackmount Sun SPARC Enterprise M3000, M4000, and M5000 servers to datacenter Sun SPARC Enterprise M8000 and M9000 servers (Figure 1). These systems implement a common high-performance architecture and utilize the latest SPARC64® processors, helping organizations maximize solution performance.
This Sun BluePrints™ article discusses the characteristics of SPARC64 processors, attributes of each individual Sun SPARC Enterprise M-Series server, and I/O subsystem behavior. Within this document, an emphasis is placed on how system features impact application performance. In addition, the article provides some insights with regard to gaining the best performance from Sun SPARC Enterprise M-Series servers and large computer systems in general. The content of this article assumes a basic understanding of server architecture, multithreaded processors, virtualization technology, and performance tuning principles.
