Hi all,

This is for anyone is in the know / has looked into this sort of thing before / has designed one / works in a Data Centre.

Im putting some thoughts together to take into consideration for design of a data centre with a network operations centre (NOC)

In the area of Network design only.

If anyone has any brief notes or knows of anywhere i can gain more information on this would be great!


Watch Question

There are many things to consider and the reason there are no straightforward directions on how to do this is because there are dozens and dozens of setups that are correct based on the requirements. You may have better luck if you make a list of some of the requirements that you have, add some details about your environment and then post that information
many many factors to consider.  Vapor Sealed room, HVAC, battery backup, Generator in case of power failure.  Ladder track systems for cabling.Raised floor or no raised floor, emergency lighting, alarm notification of temperature, humidity, smoke, water.  Power to the room.  many many things.  then what about servers, SANs, switching equipment, routers, etc.

Not the solution you were looking for? Getting a personalized solution is easy.

Hi Guys

thanks for your comments - maybe i should have been more clear.

I have taking environmental needs all into account.
we have room with raised floor for cabling.
HVAC system suppling 40kW of cooling
UPS backup diesel generator suppling over 100KVA for up to 7 days
Fire system
full alarm alerting system.

The question was focused mainly on Network design only

tthen you want to pay attention to core routers, internet routers, core switching equipment, cable type. cat5e, cat6, fiber,etc.  server types, blade servers, 1u, 2u ,3u servers.
My post was related to network design only. The obvious is that you need a router, a firewall and a switch. Anything beyond that will be determined by what you are trying to do. This could grow into failover firwalls, a DMZ, VPN appliance, an Intrusion detection system, External and internal DNS servers, DHCP servers. Again much of it will be determined by what business you are in, what you are trying to do and who your customer is.


ok, lets go down the route of a typical hosting company. offering shared and dedicated hosting environments.
the core network and management network is what i need to focus on,
as i can build up each customers required network / servers around this.

any thoughts on WAN integration with the ISP?
Management network integration. i.e. do you have a completely physical seperate network to every device?
Core network infrastructure design for highspeed backbone switching?

If you are getting into the business of hosting a fat connection to the internet is a must. At least a WAN connection that is scalable so you ca nincrease it as you grow. You will need to run a couple of DNS servers available to the outside world. It would be impractible to have a completly seperate network for each host. I have never been in the hosting business but would suspect you will need a good core switch with a fast back plane. You would want a switch that has the capability of 100+ ports so the trasfer of data is on the back plane and not jumping across gig connections between switches. Maybe someone more fluent in the hosting business would have some better insight than I. I've worked alot with the corporate and academic environment.
