Intel perhaps?
From what I read, it could centre around the Intel Atom C2000 series. My understanding is that this includes the C2718 / Avotons which I understand from other research into a low power hypervisor host, would burn out/slow down/fail after around 12-18 months use.
If it is around Intel kit, that would explain the obvious NDA that Cisco is under. Who else has the clout to impose such a thing on NetZilla?
