Based on this slide from the netapp university and the following doc, it looks to me like NVE is OKM only.
Anyone have any information to support otherwise?

https://netapp.sabacloud.com/Saba/Web_spf/NA1PRD0047/common/leclassdetail/ regdw000000003193830 On one of the slides here in the 9.1 new features document it says "Federal Internet processing standards 140...level 2 compliance, NSE systems and external KMIP server still required)
I take that to have the unfortunate meaning that NVE cannot be used with an external key management server.
