Not standard kit !
Last I've checked on the handful of HPE superdomes we have in a customer DC, the kit can't really survive without an HPE poor guy, chained to it via a laptop.
So in ISS, this is for sure ad-hoc kit.
I mean, we have like 6 SDs and dozens of IBM Pseries in said DC, and I very rarely see IBM, but it really seems, every time I get there, the HPE bods are literally living there !
