Citrix SD-WAN Platforms
smaller appliances are used at the spokes, whenever the link speed or the number of XenApp/Xen-
Desktop users is higher than can be supported by a smaller appliance.
DC to DC Replication
If you require a secondary data center, SD-WAN WANOP 4000, 5000 appliances can provide optimiza-
tion for Data-Center to Data-Center replication. This optimization improves replication time and re-
duces bandwidth consumption.
