For successful deployment of one or more SD-WAN 4000/4100/5100 appliances in your datacenter, keep the following principles in mind:
- You must provide enough SD-WAN 4000/4100/5100 peak-load capacity, in terms of WAN bandwidth and the number of users. See the current specifications sheet for the capacities of different SD-WAN 4000/4100/5100 models: https://www.citrix.com/content/dam/citrix/en_us/documents/data-sheet/netscaler-sd-wan-datasheet.pdf
- Provide enough capacity for expected expansion over the life of the deployment. SD-WAN 4000/4100/5000 appliances using the same hardware platform can have their capacity upgraded with a new license as part of the Citrix pay-as-you-grow program.
- For more capacity than can be provided by a single appliance, multiple SD-WAN 4000/4100/5100 appliances can be cascaded behind a stand-alone NetScaler appliance.
- Different models have differing numbers of traffic ports. If you require multiple bridges, make sure your model has at least as many as you need.
