Intel has a very narrow "supported" definition for OPA: Haswell-E5,
Broadwell-E5, Skylake Xeon Scalable.

I personally don't think there's anything technical behind this, just
marketing/product-positioning.

We run OPA on some old (Nehalem) nodes as a test platform for our
system environment (without problems).
