I have a Linux server acting as a gateway and VPN endpoint. It's made from an old workstation and needs to be replaced. It's connected to another router in which we configure the VPNs. The server configuration is nothing fancy, but could take a while to restore/recover.
I've had problems with this system twice before. First the HD died. Last week the PS died in the last replacement system (a similar workstation). It's been moved to another workstation, and I realize the need for a better solution (including backup and supported hardware).
I'm looking at these options:
Purchase a HP or Dell server, standard stuff with the usually redundancy.
Purchase a Workstation, again normal bells and whistles.
Virtualize the server. I'm considering rolling out Xen on one of our servers, migrating several light servers there and clear our some old equipment (have a HP DL380 G5 waiting). to our control.
With any a real backup plan would be rolled as well. I haven't work much with virtual environments.
In your experience/expertise may you provide your insights about the options and which one you'll use or if you can suggest another option that would be great too?
