New server setup, best practice?

[Alex Neuman van der Hans]

It really depends on context. Space, CPU and I/O issues can vary greatly from site to site.

If you want to upgrade, look into your biggest bottlenecks first. Sometimes it’s RAM, sometimes it’s disk I/O (where SSD’s would be great), sometimes it’s CPU power.

In my case I usually go for SSD’s for storing the OS, programs, and mail - and regular hard drives for things like quarantines and such, with scripts moving older stuff with various protocols (NFS, rsync, FTP) over to long-term storage to make space when needed.

Oh, and it’s not “virii”. Virus is a “mass noun”, like “rice”.  https://en.wikipedia.org/wiki/Plural_form_of_words_ending_in_-us#Virus <https://en.wikipedia.org/wiki/Plural_form_of_words_ending_in_-us#Virus>
