Well, noticeable again comes back to
Hello,
today we made some tests with failed drives on a zpool.
(SNV60, 2xHBA, 4xJBOD connected through 2 Brocade 2800)
On the log we found hundred of the following errors:
Sep 16 12:04:23 svrt12 fp: [ID 517869 kern.info] NOTICE: fp(0): PLOGI to 11dca
failed state=Timeout, reason=Hardware Error
Gino,
although these messages show some similarity to ones in the Sun Alert
you are referring to, it looks like this is unrelated. Sun Alert 57773
describes symptoms of a problem seen in SAN configurations with specific
switches (Brocade SilkWorm Switch 12000, 24000, 3250, 3850, 3900) with

This should, of course, set off one's common-sense alert.
it is 91 times more likely to fail and this system will contain data
that I don't want to risk losing
If you don't want to risk losing data, you need
One option I'm still holding on to is to also use the ZFS system as a
Xen-server - that is OpenSolaris would be running in Dom0... Given
that
the Xen hypervisor has a pretty small cpu/memory footprint, do you
think
it could share 2-cores + 4Gb with ZFS or should I allocate 3 cores of

Well, noticeable again comes back to your workflow. As you point out
to Richard, it's (theoretically) 2x IOPS difference, which can be very
significant for some people.
Yeah, but my point is if it would be noticeable

Glad you brought that up - I currently have an APC 2200XL
(http://www.apcc.com/resource/include/techspec_index.cfm?base_sku=SU2200XLNET)
- its rated for 1600 watts, but my current case selections are saying
they have a 1500W 3+1, should I be worried?
Probably not,
