Re: Do you run DHCP on IBM i?

OK, and when the VMWare or other virtualization got clobbered and DNS/DHCP
etc, are required for the recovery, but wait they are on the virtualized
stuff, that requires the virtualization to recover, wait my head hurts.....

Sure, run the servers on a virtualized environment, but have a hard back
up. Maybe it's even the third version of it. it's kinda like insurance,
when you don't need it, it's a real bother, until you do.

Too many times I've heard the "it's really fault tolerant and we have
backups", OK, how long to recover that stuff before the entire network is
available again? Answer: "um, we don't know it's never been done...."

Uh huh.....

Jim,
We used to follow the dogma that things like DNS servers, etc should have
their own hardware but we're backing away from that. Why use a 1U server
when you can just make it a virtual server on your vmware server? This
allows snapshots, etc. And you can always set up a redundant on a
different vm server.
Why complicate the save/restore with dedicated hardware?

I'm guessing the auditors would not like the IBM DHCP server since most of
them can't spell "i" without help. The server works just fine, however it
might not be quite as updated as one from Microsoft or on a Linux
distribution.

In the end things like DHCP, DNS, etc while they run just fine on IBM i are
usually left to external devices. I advocate a physical server since most
virtualization software relies on DNS too much, and that makes recoveries
somewhat more difficult. Backups virtualized, no sweat, primary, that
should have it's own hardware. (face it a 1U server is really cheap)

Bossman says IBM told him not to run DHCP on the IBM i server so we have

anyone
shed light on this? Do you run DHCP for your LAN on the IBM i? If not,
what
solution do you use for your workplace LAN?

Thanks.
