If you want to scale, run e.g. HAproxy before a cluster of HA

It is obvious that a DRBD HA solution push availability
of nonredundant components into useful range. E.g. I run single-disk (non-RAID)
Atoms with nonredundant power supplies. However, they're cheap
enough (kit 300 EUR, add memory and disk) to run in tandems.

Especially if you run two vserver guest pools on each,
using active/active, so you don't lose half of the (meager) performance.
