Curious if anybody has experience with an all flash FAS deployment?    We currently utilize Flash Cache and Flash Pool backed by SAS 15K and 10K drives but are considering an all flash FAS solution for our next system.    

What prompted you to go with an all flash config versus leveraging flash as a cache tier?   What size SSD's are you using?  

Not interested in an E-series array as we depend upon the features of ONTAP.   Also not interested in fronting an E-series array with an ONTAP system.    I am aware of the 96 disk per stack limitation that goes along with FAS and flash.  

Cheers!
