Are there any links to best practices or validated design guides for iSCSI in VXLAN deployments ?

I am cross-posting the same information (for others' benefit too) we provided you in the support case,
iSCSI is based on TCP, and you should configure the interface to 8950 (to accommodate the VXLAN header on an Ethernet segment).
You can use ping command to verify the max allowed MTU. the following command will set do-not-frag bit and specify payload to be 2000 bytes (so add packet headers to this number during your calculations)
ping -M do 126.96.36.199 -s 2000
