So what are the failure modes to worry about?

I'm not exactly sure what the implications of this nocache option for my 
configuration.

Say from a recent example I have an overtemp and first one array shuts down, 
then the other one.

I come in after A/C is returned, shutdown and repower everything.  Bring up the 
zpool and scrub it I would think I should be good.

Any other scenarios I should play out?

I really like mirrored dual-array setups with clustered frontends in failover 
mode.  I want performance but don't want to risk my data, so if there are 
reasons to remove this option from /etc/system I will do that.

I still see little or no usage of the cache according to the status-page on the 
3310.  I really would expect more activity so I'm wondering if it's still not 
being used.
