Well, that really depends entirely on how you spec the machine, and how
busy that site is...
The ones I admin for a couple of my clients are speced at 8G or 16G RAM
and a quad-core low-power-consumption CPU. All run a number of virtual
machines (Debian 6.0 with libvirt/KVM, or Debian 5.0 withOpenVZ).
Performance is excellent, I use them with Linux's md software RAID, and
no HW-RAID controller (which is a feature as far as I'm concerned - you
get excellent performance, and you don't have to worry about things like
having to only use Dell-branded drives - because you don't have the
firmware compatibility issues with their fussy HW RAID controllers -
same goes if you want to use Intel (or whoever's) SSDs etc.).
You CAN hot-swap the drives, although they aren't in hot-swap caddies
(as they're just plain Intel ICH10 SATA - just use 'hdparm -y' to
spin-down the drives first - as is best-practice when using hot-swap
If the max spec is sufficient for your needs, and you don't need the
hot-swap caddies, then I don't see any reason not to use an R210.
Of course, the person in Dell sales will tell you that it's a terribly
low-spec machine, and you should really be buying something with a
bigger price tag and profit margin (they certainly did to me), but they
just automatically trot that marketing BS out - if you've done your sums
right, then you should know whether it'll be fast enough for your needs
