In the Past HPE did only certificate the last two Generations means in the momen Gen9 and Gen10.
I don't see a chance that HPE will do any support or certification for older models. HPE will sell servers...
We also discussed this cause the Gen7 problem with vmware and with hpe and from both sides was no interest to fix the problems. For us it is a sign to take a look to other hardware vendors how long the support their systems for vmware.
