2 minute readPerformance Troubleshooting Series: Planning Ahead to Avoid Performance Bottlenecks with Line Cards

One of the things that can cause performance issues is a lack of capacity of ports with your system. So, the question is – how do you prepare for this in order to prevent performance issues?

Tracking Events to Avoid Performance Bottlenecks

Tracking the events coming through the pipeline on your environment can definitely help your organization forecast the needs of your environment in the near future. Keeping track of the estimates of how many servers will be deployed within the next 6 months to a year will then allow you to keep an active inventory of the amounts of ports available in your switches.

One measure that you may want to consider is that if you’re hitting 80% capacity in your fibre channel network in terms of ports consumed,you should initiate an event where you would go look into purchasing additional line cards.

 How Many Line Cards Do You Purchase?

The amount or density of line cards you will need to purchase will depend on the metrics you obtained in your forecast of determining the amount of growth you are expecting over the next 6 months or so.

If you’re not expecting a huge amount of growth or influx of service, then you can purchase one line card with 48 ports. If you’re seeing extensive growth, you should purchase more. But, don’t forget that you don’t usually purchase just one line card at a time.

In any well architected fibre channel network, you’ve got two fabrics – an A side and a B side. This is what allows you to achieve multipathing on your client host. If you’ve got a true multipath network, then when you go to purchase one line card, you’re actually purchasing two because you’ve got two core switches that you need to expand.

These are just a few things to consider when looking at purchasing more line cards and determining how many your organization will need. Essentially, this number will rely on accurate metrics and forecast.
