compare with a Sun-integrated Solaris system, then. The availability
problems still exist according to reports on the list.
With 7000 series (aka Amber Road)?
and I had my issues both with EMC Symmetrix and EMC Clariion series,
including unexpected downtimes, couldn't access data on Symmetrix and it
took some time for EMC engeeneers to "unstuck" some IOs in their firmware,
then an endless fsck loop on a nas version of clariion, then a data loss
on clarrion with sata drives... some other stability issues with
celerra...
all in all I like their products, they are really good.
But it doesn't mean they are bug free and don't have their issues - they
definitely do.
If a reliability is your top priority you want a nice end-to-end
integration, validation, etc. It always has been like that - storage or
not.
What zfs allows you is to (carefully) take some relatively cheap HW and
provide a reliability sometimes even better than much more expensive
solutions. But still it doesn't mean you'll get there with whatever hw
junk you put together - you won't.
