[Info-vax] Difference(s) bw Itanium and Integrity Servers ?

[DTL]

Hell Happy Tax Payers,

Someone woke me up from my retirement (I'm 68 today, yes) to perform some "training" to a French Customer.

Why not?

Reading about HP, HPE, VSI and such (Hi Clair, we don't know each other, do we?), I read the 2019 RoadMap and noticed something new (to me): Integrity Servers.
I found something on WP about it, but the article is not clear.
An Integrity server is a cluster of Itanium systems?
Or a new marketing name for Itanium?
Or what?

Light appreciated, please.
Many thanks!

DTL
