I think that was me you asked about those three items.

 

AND we still use 8.8.8.8 DNS resolvers.

 

I know, it’s bad, but one of my upstreams is directly on Google CDN so it 
‘applies’.

 

I do like redundancy though.

 

So if you use one CCR, get two of them for your project, they are relatively 
cheap.

 

With fiber you really don’t need the extra servers for bandwidth shaping, I 
just shape at the CPE or switch port.

 

So in one cabinet you put say a 144 count panel and splice on, then get a SFP 
switch and two CCR routers.

I have used the 1036 CCR in some areas to start, and a pair of those running 
VRRP between them works great.

Plug both into 10Gbps SFP+ ports on the switch/switches and you have ‘standard’ 
redundancy.

 

Meaning you can bring in two 10Gbps links, one to each of the CCR units, and 
have redundant SFP+ links to the switch bank as well.

 

They have more than enough horse power to run DHCP, NAT, DNS etc between them 
to fill the duties for the cabinet/site.

 

Get a UPS, I use Alpha, and four batteries on it should work well.

 

Cabinet can be 20AMP and run plenty of switches on that.

 

I also buy an AC unit and attach it to the side of the cabinet.

 

I put some monitoring in there on a separate managed network to keep track of 
power and heat/temp and track the switches/CPE’s etc.

 

That’s about it.

 

Rinse, repeat.

Guess I don’t need DNS.  8.8.8.8 seems cheap and easy...

Had a subdivision developer contact me, wanting service for their hundred or so 
homes.  

I can get DIA close to the area at a reasonable area.  It will require some 
build but that is OK, that is something I feel some level of expertise.  

 

Considering a minimal NOC build.  

 

I asked this question of someone once before and I cannot find their answer.  
Not sure if asked on the list or not.  But the answer went something like this:

 

  1.. Buy a big CCR. 
  2.. Hire Linktechs to configure it. 
  3.. Put in a big switch for the AE SFPs and rock and roll.  
 

I am sure I would need at least one server.  DHCP, NAT, DNS?

But can all of that be provided by the CCR?

 

What is the smallest NOC configuration that could be created?

 

Batts, rectifier, cooling.  

 

I really could put all this in a cabinet on the corner of the street.
