We don't have any of these nodes at RAL T1 yet.
Which Viglen model number are these, HX225i/R or HX225a/R? As far as I
know they are the same chassis but with different mobo/cpus.
Our twins (viglen and non-viglen) and disk server PSUs are very reliable
- only two disk server (1+1 redundency) PSU have failed in 2 years.
