If you change your mind about using a local SSD drive in your 5.5 ESXi host for virtual flash, but find that it won’t seem to let it go take a look at VMware KB article 1036609
I configured virtual flash just to see what would happen, then decided to use the SSD for VSAN instead. Only, after disabling the Virtual Flash Host Swap Cache Configuration, the “Remove All” button on the Virtual Flash Resource Management page told me “Host’s virtual flash resource is inaccessible.” and “The object or item referred to could not be found.”
Fortunately I found the KB article above and used
ls /vmfs/devices/disks/
to identify my disks and
partedUtil delete "/vmfs/devices/disks/mpx.vmhba1:C0:T0:L0" 1
to delete the partition on my SSD drive
