ODX - Inconsistent behavior on different servers

-

hi,

i have installed couple of new hyper-v hosts in our prod. environment , have noticed odx "works" on 1 of them. config looks like:

host a: hp proliant dl380e g8 / windows server 2012 datacenter

host b: ibm bladecenter hs23 / windows server 2012 standard (limited # of vm's on one)

storage: smb3 share on netapp filer (fas3220 - clustered ontap 8.2.1)

reg key hklm\system\currentcontrolset\control\filesystem\filtersupportedfeaturesmode has same value, being 0 (=odx enabled), on 2 servers. 

when copy, host a, vhdx file on smb3 share (to same share), can see odx being used (no traffic on netw. interfaces , tokens file's modified date gets updated current timestamp). when exact same operation host b (same share), can see data being transferred to/from host (and token file's modified date not being updated). besides 2 2012 servers, i've installed 2 2012r2 servers , don't appear using odx either.

could tell me if there's setting in server 2012/r2 has influence on how odx performs or if i'm missing something?

thx lot.
