Maybe the best thing here is to have us (i.e. the people on this list)
come up with a set of standard and expected use cases, and have the ZFS
team tell us what the relative performance/tradeoffs are.  I mean,
rather than us just asking a bunch of specific cases, a good whitepaper
Best Practices / Cookbook for ZFS would be nice.


For instance:


compare UFS/Solaris Volume Manager against ZFS in:

[random|sequential][small|large][read|write]
on
UFS/SVM: Raid-1, Raid-5, Raid 0+1
ZFS:  RaidZ, Mirrors




Relative Performance of HWRaid vs JBOD
e.g.

3510FC w/ RAID using ZFS
vs
3510FC JBOD using ZFS



I know a bunch of this has been discussed before (and I've read most of
it :-), but collecting it in one place and filling out the actual
analysis would be Really Nice.
