Just to say thank you all for your responses.

I will tell you the final set of NTP servers =)

Not too old, though. I've had problems with clocks in aging hardware (e.g. a
Pentium II machine about 5 years ago) starting to drift so bad that not even
NTP could keep them in sync. That being said, prices drop fast enough so that
you can find fairly recent machines at very low prices.

A Rasberry Pi would suffice (but it's not supported by OpenBSD).
Any old server you have lying around will be more than enough.

Don't virtualize your ntp servers.

Question about NTP server

[Leonardo Santagostini]

Hi @misc, i am about to mount 4 ntp servers.

Main goal is to serve approximately 300 servers and 300 hundreds
workstations

Servers are located at one datacenter and office in other place. I have a
couple of doubts for asking to you.

1) Is there some calculus for making those ntp boxes efficient in terms of
not overstate (sorry, but english is not my mothers tongue) or right size
the hardware.
2) Im wondering also to set up this boxes virtualized using KVM. I know
that using RTC its a really pain in the ass, but maybe you can give me some
advice for this config.

Thank you all,

Best regards/Saludos.-
