At its conference for analysts this week, Sun Microsystems will outline the direction in which it's headed with its UltraSparc processors and its datacentre management initiative. During briefings on Monday and Tuesday, the company is expected to articulate its strategy to fight encroachment in the server hardware market by Intel-based rivals such as Dell Computer and to capitalise on its Java programming language and Solaris operating system. Central to Sun's plans are a redesign of its UltraSparc line of processors, meant to leapfrog the competition, and software improvements that will lower the cost of datacentre operations, George Papadopoulos, Sun's chief technology officer, said at a briefing with reporters last week. Sun will discuss plans to employ the next generation of the UltraSparc processors in blade servers, which are expected to be released next year. The systems will exploit so-called "multicore" processor technology that Sun acquired from Afara Websystems last year. A multicore-processor design allows a manufacturer to place more than one processing unit on a single silicon wafer, leading to more computing muscle and lower energy consumption. As previously reported, Sun will finish work on the UltraSparc IV chip in the second half of this year that etches two processors on a single slice of silicon. With Sun's follow-on processors, the company will be able to create the "equivalent to a 32-way SMP (symmetric multiprocessor) on a chip," said Papadopoulos. Because this multicore-processor technology is relatively immature, Sun will be deploying the chips on single-function servers, such as Web servers, rather than high-end servers that handle demands such as high transaction volume, he said. IBM has already employed a dual-core architecture on its Power4 processor, and Intel is pursuing the same technology for its Itanium line of chips. Although processor technology to handle computing tasks in parallel has been around for years, applications typically had to be written specifically to take advantage of a processor's ability to break up computing into several parallel processing tasks, or "threads". But as applications become less dependent on the underlying operating system and chip architecture, businesses will be able to more easily take advantage of multicore processors, Papadopoulos said. "Developers should not be writing to operating systems," he said. On the software side, Sun will detail plans to bundle its Java-based middleware with its Solaris operating system and improve the logical partitioning in Solaris. The partitioning capabilities, code-named Kevlar, will allow a single machine to effectively run several applications, each in its own dedicated subset of the operating system, to ensure better security and performance, Papadopoulos explained. The briefing for analysts will also serve as a forum to describe the next phase of Sun's strategy for automating datacentre operations. Sun used the analyst conference last year to tout its N1 initiative to create a "network operating system" that will allow companies to allocate computing resources more flexibly, according to demand. The idea is to give administrators more control over the hundreds or thousands of servers and storage units in a data center in order to lower operating costs. Sun will also seek to simplify the lives of system administrators, as well as software developers, with a programme to bundle and release various software components on a regular schedule, code-named Orion. Much like Sun releases updates to Solaris each quarter, Orion will serve as a "delivery vehicle" for Sun software, Papadopoulos said. Included in Orion will be Solaris and the Sun ONE suite of Java server software and tools. Sun will test and certify that various versions of components, such as the network directory and Java 2 Enterprise Edition (J2EE) server software, function smoothly together. "(Orion) promises interoperability of components and also simplifies operations," Papadopoulos said. Although Sun was late to develop its own strategy for selling servers for the Linux operating system, Papadopoulos said that Sun will sharpen its focus on software for Intel's 32-bit processors, which run both Linux and Solaris.
