Ok, so first things first...I made a mistake. Not sure how because it's not how I planned to set it up, but eitherway, attention to detail can kill you sometimes!
I had intended to made a bunch of mirrored vdevs. I wanted to have two mirrored ssds as my slog. However they ended up included with my main storage.
So this whole time i've been running with no slog and a single ssd as my l2arc.
So now I have a single drive as my slog and two drives striped for my l2arc.
We've now noticed a drop in performance. I've been told these intel 530 ssd's won't be the best and they aren't.
SO in the interest of starting a conversation about this, how safe is it really to run without an slog and when do you really want to put one in?
There is the option of adding in a pcie intel 750 when I can get my hands on one..but really... do I need one?
We have UPS power for 1 hour and in about 4 weeks we'll have a natural gas cummins generator. So.... do I really need an slow?
We host a ton of terminal servers on vmware iscsi, so l2arc seems to be helping there while we only have 64gb of ram...just not sure about the slog!
Thoughts?
