Has anyone come across the advisability of running an enterprise-wide NTP
server under an AIX LPAR?
We're currently running NTP on old Intel hardware and the company policy is to
refresh hardware on a regular basis.
It seems a waste to buy several new servers if we could just put the NTP
service on an AIX LPAR.
I'm at a large company, serving NTP to over >1000 systems.
Policy is that we can't have old hardware, so they will spend several thousand
$$ on servers to run a single process. (we're an IBM/Lenovo based shop)
Technically, yes, this is a virtual machine, but this is on 250K$+ hardware,
not something like ESXi or Xen.
(and CPU/RAM/hardware can be dedicated to the LPAR if needed)
These boxes are meant for heavy lifting, the same type of frames power AIX,
iSeries, IBM mainframe, and Watson.
Is there a way to test? It seems like I'm heading into the unknown here. :)
There is indeed a way to test: "Just do it!"
I worked for many years in a similar enviroment (large multi-national
corporation with factories/offices in 100+ countries), our LPAR based
AIX machines were very stable.

PS. I did use to run our ultimate NTP reference clock on a hand-soldered
GPS board hanging on the side of a FreeBSD (v 4.x probably, i.e. a long
time ago) box under my desk.
A number of years later I finally got the money to do a proper job,
that's when I setup 3-4 geo-distributed GPS-based Stratum 1 clocks (from
3 different vendors), with a second layer of 6+ Stratum 2 machines.
The S2 machines used all of the S1 servers plus a set of vetted external
S1 and S2 reference servers. All other internal machines used all the S2
servers as their configured sources.
