<br>
So you could have the following:<br>
<br>
FreeBSD labels USB3 Flash drives as dax<br>
<br>
da0s1 - boot<br>
da0s2 - host\petitecloud<br>
da0s3 - vm storage<br>
da0s4 - l2arc<br>
da0s5 - zil - only useful with certain writes.<br>
<br>
However there would have to be testing for certain OS and flash drive combinations. I am certain if it is solely a Windows limitation but I have never been able to get multiple partitions on a flash drive using windows but I have heard of people doing it so i assume they used a *nix distro.<br>
<br>
The other option is using two flash drives as such:<br>
<br>
da0s1 - boot + host\petitecloud + vm storage<br>
da1s1 - l2arc<br>
<br>
ZFS is able to mount disks based on their GUID's instead of device assignments which allows flexible use of external storage.<br>

Can this be used as a cloud on a stick? (i.e. I can take it out the host that made it and stick into any FreeBSD capable machine and it will boot PC and it's instances)<br>

I have confirmed that USB3 flash drives can serve as L2ARC caches<br>
for ZFS. I am using a Kingston Hyper-x 64GB USB3 for my tests and<br>
it significantly increased writes between 3 and 10 fold for<br>
datasets with dedup set to verify.<br>
<br>
Just thought this would be helpful for deployments where 100% SSD<br>
nodes may be either impractical or out of budget and Ram capacity<br>
is limited.<br>
