It appears the first line of my email disappeared. Here it is again.
I have been looking for some server sizing information for ISC
DHCP. I know the queries per second that any given piece of hardware
'could' handle is a relatively random number and I've understandably found
a lot of differing opinions on it. What I have not been able to find is
information on the physical size of leases file and how much data the
DHCP service logging is going to add to the syslog (or wherever its put)
for a given address pool and lease time. Does anyone have a link to that
information or a good estimate from their experience as to what I might
expect in the below environment? Does going to a failover setup add a
noticeable percentage to either of these numbers?
60,000 available address
350 scopes
25,000 clients
approximately 300,000 queries per day(average 4 queries per second)
