Also new is the Linux Application Environment, code-named Project Janus, which lets Solaris 10 and native Linux binaries run side by side with no modifications. Read more here about Janus and its delays. The new 128-bit Solaris ZFS file system has 16 billion billion times more capacity than current 64-bit file systems, he said.
But Suns Loiacono told eWEEK that when the first production version of the new Solaris 10 operating system ships, it will likely not include the new 128-bit Solaris ZFS file system or the Linux Application Environment (Janus) technology that allows Linux binaries to run natively on Solaris.

"The ZFS file system, which automates many common tasks for system administrators, may not make it until the first update after Solaris 10 ships, which should be within two quarters of that initial ship date," Loiacono said last week. "This revolutionary new file system required a lot of work and we had to make sure it could meet the quality standards we set for Solaris in general, and so we decided we would pull it if necessary."
Longtime Solaris users such as Thomas Nau, head of the Communication and Information Centers infrastructure department at the University of Ulm, Germany, say they would have liked to see ZFS in the initial release because it is the only bundled file system that really supports file systems larger than 1TB without introducing other limitations. "We require ZFS to handle our large file systems more easily as we are approaching a number of limits," he said James Dobson, a systems architect at Dartmouth College, of Hanover, N.H., said he is interested in Janus since the college uses Solaris, mostly on Sun SPARC hardware, with more on x86 and x86-64 hardware expected in the future. "My vendors ship i386/Linux binaries—more specifically, Red Hat Enterprise Server/Advanced Server. I run these on Fedora and other free Linux distributions. I would like to run these on Solaris if possible," Dobson said. But he said an important question that must be answered is why Sun is doing this. "Is it a transition tool? A porting tool? A real tool for production use? I think we would all prefer to run native applications," Dobson said. "If Sun is not able to get ISVs to port to Solaris x86, then Janus becomes critical for the success of their platform. Thought is required as to why they are doing this so it can meet the needs of customers," he said. "It should, for example, allow me to run graphical applications—interactive, like Mathworks Matlab. Some plans Ive heard suggest it will be run in virtual machine, in a Linux "zone," which may not let me use Janus on the workstation."

He was responsible for a national reporting team of 20 based in four bureaus. He also edited and contributed to its weekly technology page, and launched a financial and technology radio service supplying daily news bulletins to the national broadcaster, the South African Broadcasting Corporation, which were then distributed to some 50 radio stations across the country.

He was then transferred to San Francisco as Business Report's U.S. Correspondent to cover Silicon Valley, trade and finance between the US, Europe and emerging markets like South Africa. After serving that role for more than two years, he joined eWeek as a Senior Editor, covering software platforms in August 2000.

He has comprehensively covered Microsoft and its Windows and .Net platforms, as well as the many legal challenges it has faced. He has also focused on Sun Microsystems and its Solaris operating environment, Java and Unix offerings. He covers developments in the open source community, particularly around the Linux kernel and the effects it will have on the enterprise.

He has written extensively about new products for the Linux and Unix platforms, the development of open standards and critically looked at the potential Linux has to offer an alternative operating system and platform to Windows, .Net and Unix-based solutions like Solaris.

His interviews with senior industry executives include Microsoft CEO Steve Ballmer, Linus Torvalds, the original developer of the Linux operating system, Sun CEO Scot McNealy, and Bill Zeitler, a senior vice president at IBM.
