Why does capacity planning matter?
Capacity planning allows NetOps to practice data informed decision making when rolling out network changes
See what devices, (ex: bridges and switches) are reaching capacity most frequently and which are servicing the least links. This is an indicator you may want to replace equipment or add more ports before starting a change initiative
Once you have baselined the capacity of each link and piece of network equipment, you have a control variable to compare new equipment and applications against. Plan ahead for additional requirements of a new application before capacity is exhausted.
Knowing what capacity each component of your network can manage, allows you to calculate and anticipate when new infrastructure will be required.
Baselining helps you understand where your network resources are going and allows you to see if you are compliant with network management policies.
A performance baseline gives you historical comparison for network changes and a point of reference to contrast with when irregular network patterns occur.
Right-size your network
A network capacity assessment lets you stop the over / under utilization guessing game and create precision-based network architecture.
Here’s a practical example: when hiring new remote employees, capacity planning knows the exact capacity of the segment that connects new employee endpoints together and the capacity of the links that carry the traffic between the terminals and applications they will be using.
Make sure your service providers and third-party vendors are hitting their SLAs with service-assurance verification. Verify and report on service assurance KPIs with capacity reporting.
To improve availability and audit readiness, IT organizations should evaluate tools to detect changes across IT services, systems and software against a range of policies.
