PowerVM Scale Out

We're not entirely sure a separate PowerVM Scale Out chip exists. PowerVM can be licensed directly for use on the OpenPOWER systems if desired. SiteAdmin (talk) 12:46, 2 January 2018 (CST)

I had definitely heard about this on the Level1Techs Forums; searching through early posts in the thread I came across a reference to an AIX Virtual User Group “webinar” wherein at ~33:00 is fairly clear about dual-socket PowerVM chips being this direct-attach RAM Scale-Out variant. I guess they could have cancelled it later on? If I feel up to it, I could go skimming through the different redbooks and see if there is some mention of dual-socket IBM i/AIX machines having a non-Cumulus chip.

This 2018 IBM POWER9 Family (PDF) document definitely seems to suggest that SMT8 Scale Out was a possible configuration, and it does have the Scale Up/Out + SMT 8/4 grid diagram; however, the “PowerVM Scale Out” machines it references seem to have more RAM slots than the AC922; suspicious.

Research for evidence of non-Nimbus LaGrange modules

I found a tweet from an ex-Rackspace employee talking about SMT8 chips also being packaged as LaGrange. I plan to add more here later. AbstractConcept (talk) 15:06, 12 March 2020 (CDT)
