What is Capacity Planning?
Capacity planning is ensuring that the network has the resources it needs to prevent an impact on business-critical applications. There is no easy way to determine when action needs to be taken to prevent an outage. Whether you’re ensuring that there is enough bandwidth through a service provider, or verifying the load on network devices, having full awareness in a single view is paramount. Luckily, LiveNX, our Network Performance Management solution, provides unique benefits that can solve your capacity planning issues and protect business-critical applications. Below, walks through the top four capacity planning benefits of LiveNX and recommendations to consider as you develop your capacity planning strategy.
1. Eliminate Bandwidth Complexities and Metrics
LiveNX delivers a single page to alleviate the complexity bandwidth visibility problems and provides metrics regarding both bandwidth and device strain. You can witness this by viewing the WAN Interface Capacity story, located in the LiveNX Web menu.
2. Cut Costs and Achieve an Uninterrupted Service
Why pay for more bandwidth than you need? Once devices and interfaces have been appropriately tagged, LiveNX can track bandwidth usage, 95th percentiles, and the percent changed month over month. After toggling through a few months via the filters, an accurate projection of future bandwidth consumption is easily attainable. Having an estimate of the future bandwidths with actual data will aide against exceeding service provider limitations on sites that may be expanding or experiencing excessive bandwidth consumption.
3. Be Aware of Load Balancing Equipment
Another important aspect of capacity planning is CPU/Memory management. If the CPU on a device is under too much stress it may increase latency or in a worst case, crash. Thereby, putting an additional load on other devices, which could cause a catastrophic chain reaction. Likewise, insufficient memory could cause routing operations on a device to fail. Being aware of growing CPU/memory usage on devices will help ensure high-availability of the network.
4. An Ounce of Prevention is Worth a Pound of Cure
Being contentious of any growing demand in either bandwidth, CPU, or memory, has the potential to save money and reduce those “oh no!” moments.
