Re: Migrating DNS servers, need advice on hardware
You need to consider three components for memory: OS + other services; the zone files you load + cache you want.

Many thanks Pedro :-) I think since I plan to run with Linux at first say 2-3GB memory should be fine as I will use Zimbra and Apache with it too on 2 physical boxes. That should be ok. Although when I migrate to OpenSolaris I may need a bit more, say 4GB depending on what else I will have running. But I think definitely the way to go for me looks to be running multiple services on one machine unlike now where my machines aren't powerful enough. Since a dedicated machine for my home setup for just one specific service I reckon will be overkill and unnecessarily increase my budget. ___ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users

Perhaps the inverse would be more interesting: what's the lowest-spec hardware that could host an OS that would run the latest version of BIND. =) Frank -Original Message- From: bind-users-boun...@lists.isc.org [mailto:bind-users-boun...@lists.isc.org] On Behalf Of Barry Margolin Sent: Saturday, September 19, 2009 12:09 AM To: comp-protocols-dns-b...@isc.org Subject: Re: Migrating DNS servers, need advice on hardware In article , Kaya Saman wrote: > > > > Since you haven't mentioned how many zones and records you're hosting, > > how do you expect anyone to guess how much hardware you need? > > > > > Yes thank you for pointing that out!

In private email, he told me he has 59 forward and reverse records in the internal view, and 22 of each in the external view. This is nothing.

It's not Bind or perhaps is some sort of hacked out version but
basically since Cisco IOS comes with it's own DNS server which I have
dabbled in on my 857W at home, being based round BSD I presume with the
right OS one could run Bind comfortably on that??
Taken from output of show version: Cisco 857W (MPC8272) processor
(revision 0x200) with 59392K/6144K bytes of memory.
I'm pretty sure the little 857W would run Bind if someone actually was
able to build BSD on it or so.. it has 64MB of RAM too so should be
good enough for at least 5 people. {provided one takes out the systems
routing capability though as the way I use the router is maxed out lol}

Re: Migrating DNS servers, need advice on hardware
A very decent performance can be achieved on a K6 330MHz with 128MB, also running all sorts of other servers. This HW is from about 1995 and still sufficient for BIND and more.

Re: Migrating DNS servers, need advice on hardware
Small home linksys router running open WRT can do the job, with 16MB of RAM and some low powered MIPS CPU.
