Hardware, Embedded Systems ACM's latest journal had an interesting article about RAID which suggested it might be time for triple parity raid. "How much longer will current RAID techniques persevere? The RAID levels were codified in the late 1980s; double-parity RAID, known as RAID-6, is the current standard for high-availability, space-efficient storage. The incredible growth of hard-drive capacities, however, could impose serious limitations on the reliability even of RAID-6 systems. Recent trends in hard drives show that triple-parity RAID must soon become pervasive."

D. Last and not least, while ZFS is -a- solution to improving the resiliency of RAID arrays, in my view, the OS lock-in, patent issues (that prevent other OS from implementing a kernel version of ZFS), and less than ideal implementation makes ZFS a far from ideal solution.


For the last time: there is no OS lock in. I've been patient with you but you keep on spouting this BS.

You keep moaning about choice and how people should be open to other file systems, but so far all I can see is you blithering on about how ZFS won't run on your favourite OS.

In fact, you're starting to come across as the type of person that many of the ZFS engineers at Sun were fighting against when drafting up what license to apply to their file system.
The sort of person that expect everyone to bend over and kiss the holy grail of GPL as if it was the second coming.

I mean seriously - you've made 2 good points and the rest of your posts have been a self-indulgent CDDL rant loosely masquerading as a scientific argument (and your rant is particularly worthless given high end virtulisation costs nothing these days)


Yes you don't like the joined-up layers of ZFS - but that's opinion. There's no "right" or "wrong" way - just a preferred way.
Yes you'd like to see more universal standards.
But lets not overstate the facts just so you get some attention while stood there on your soapbox.
