Hi guys, we are creating a data center and we want to shape tha bandwidth to each of our rack.
What kind of shaping would be better? It have to be configured on the switch L3 connecting the racks (each in a different vlan) or on the router connected to our provider?
Well, if you are a hosting company then you usually offer different bandwidths for different packages.
For any kind of company, you might be wanting rate shaping as a prioritization mechanism, especially if your equipment does not support as many prioritity queues as you would like.
There are companies that don't mind employees using the internet for optional services as long as it doesn't interfere with the efficient operation of the company.
Or you might simply not have enough money to provide unconstrained bandwidth when some of your customers might be using bitTorrent or the like -- applications that will suck up as much simultaneous bandwidth as you give them, but which will live comfortably with bandwidth restrictions.
One option is the use of an actual traffic-shaping appliance such as the PacketShaper by Packeteer or the Alot NetEnforcer. The Packeteer ISP models are capable of enforcing SLAs quite easily.
