Right? When "full" virtualization happened , we went from LPARs to VMs but the terms were used SOOOOOO interchangably . Similar to then p-series / i-series became POWER in 2008 and now getting close to 20 years later, I still hear p-series more often than one might think.

Serial? POWER4. Back when the term 'Logical Partition' made sense. They should have renamed it to 'Virtual Machines' when micro-partitioning was introduced on POWER5.

Changing from serial to ethernet was awesome. Also moving off of WebSM - good times.

It's been this way for quite a while. At least since V7.
V5 HMC which came out with Power5 couldn't manage Power4 or though. The connectivity from the HMC to the FSP changed from serial to Ethernet with Power5. Power5 was also the start of PHYP as we now know it. Power4 wasn't as functional - no VIO, no shared etc, just dedicated CPU, Memory and I/O.

@Phill Rowbottom,
Makes perfect sense. Seems to fit right in with how IBM does things.

A HMC release supports N-2 generations of Power as it's lowest generation (down to). R11-2=Power9, R10-2=Power8, R9-2=Power7......

Yes, me - just yesterday :-)
Direct upgrade from v1062 with latest PTF (GUI "HMC Upgrade" from IBM website) was straightforward.
The very first login attempt complained about some strange errors but no more problems since then.
Warning - it really does not control any Power8 servers.
Works fine with Power9, no P10&11 in my lab yet...
Regard Igor.

How's the stability?
According to FLRT V11 required for Power 11. I just want to get ready.
