Sizing Netflow Collector solution

[jderrien]

Hi There,

Does anyone aware of any Cisco documentation that gives recommendations on sizing a Netflow collector soution ?

IE: number of routers an NFC can receive netflow export from. When does it make sense to use several collectors based on the number of routers and their location, the # of flows etc...

There's a reference to an NFC sizing calculator in the product Q&A but no actual link. I've seen a competitor product list NFC as "5 routers per collector depending on flow rate", so take it with a grain of salt.
