General Development

ZFS is the world's most advanced filesystem, in active development for over a decade. Recent development has continued in the open, and OpenZFS is the new formal name for this open community of developers, users, and companies improving, using, and building on ZFS. Founded by members of the Linux, FreeBSD, Mac OS X, and illumos communities, including Matt Ahrens, one of the two original authors of ZFS, the OpenZFS community brings together over a hundred software developers from these platforms.

ZFS plays a major role in Solaris, of course, but beyond that, has it found other major homes? In fact, now that we're at it, how is Solaris doing anyway?

Kebabbert,


"Linux has never been tested on larger servers than 8-sockets, so I would be very surprised if Linux could scale well."

"But I dont like lies and FUD. To that I react and I want to dispel FUD."

"-IBM Mainframes have very weak cpus, they are not strong. No matter what IBM says."


So you admit that you've never seen the data? Neither have I. This is the problem; everything you or I say is mere speculation.

Surely it must have been tested by oracle on an apples to apples comparison, but we just aren't allowed to see the results they don't approve of. Off the top of my head VMWare does the same thing and it's annoying as hell that their marketing heads say one thing and third parties aren't even allowed to publish contradictory evidence.

I use&like Oracle's database products, they're top notch, but censoring benchmarks sure is fishy. You are clearly taking everything oracle says at face value, and provided that I were to take everything they said at face value, then you are right: linux scales poorly.

However I frankly wouldn't put it above them to employ the same marketing FUD and bias that you are accusing their competitors of doing. Understand that I'm just trying to explain why I'm skeptical, not trying to persuade you that you are wrong. Like you, I just don't have the data that would settle the question in factual terms.

"-Linux scales quite bad. No matter what Linus Torvalds say."

"-Linux code quality is non optimal. Which Torvalds and other kernel devs agrees on."

I actually agree with you, the code quality isn't great and IMHO the kernel abstractions are poor. Linus refuses to have stable API/ABIs and consequently individual pieces of code are rarely stable even if they don't have bugs in them. I have many gripes with linux and am not a blind fanboy, however none of this actually speaks against linux scalability on SMP.

In order to form my opinion on the matter, I'd want more impartial data, and ideally some evidence that the system is correctly configured.
