Five-minute polling may be alright for much of the infrastructure. It is incredibly inadequate for a critical link carrying latency-sensitive data. A 10-second, 100 percent spike-completely obliterating the SLAs of all critical applications -- will be reduced to a 3 percent bump (or even less) on a five-minute polling cycle. Even a 30-second event is going to be reduced to only 10 percent. Being able to poll critical links at high frequencies - 10 seconds or below-will give you the information you need to address transient issues (if you can call an issue lasting 30 seconds transient).
Managing bandwidth needs and consumption is a discipline that has existed since the first 150bps modems connected computer systems together. Today, with multi-gigabit links becoming an everyday reality, we are still facing the same conundrums. Only the number of zeros has changed.
Vess Bakalov, CTO for SevOne Inc., says one thing to remember is that bandwidth and bandwidth management is a means to an end, and not an end in itself. We need adequate performance for our applications and users for the minimum expenditure. To do this effectively, we must first understand what “adequate” means for these users and applications. Only once this often-omitted step is completed can we effectively employ any bandwidth management techniques.
