Hello elementx,
Thank you for your reply.
I understand that NetApp isn't motivated to use resources to continue improving tools for vsphere 8 that NetApp decided in future to discontinue such as NDE (deployment engine) and Easy Scale (semi-automated cluster scaling).
We are completely fine with manual installation of ESXi 8.x on NetApp compute nodes without the use of NetApp additional tools build for vsphere 8.x.
From production perspective it is important to us just that NetApp send required information to VMware that ESXi 8 can be installed on NetApp H410c compute nodes so we don't lose VMware support in case of upgrade from ESXi 7 to ESXi 8.
As per your advice, we will also contact NetApp support for additional information.
