Citrix SD-WAN 4000 and 5000 WANOP Appliances

Citrix SD-WAN 4000, 5000 WANOP appliances are high-performance WAN accelerators for busy datacenters. These appliances combine multiple virtual accelerator instances with a single virtual instance of the NetScaler load-balancer, providing the performance of multiple SD-WAN WANOP appliances in a single package.

Citrix SD-WAN 4000, 5000 WANOP WAN accelerators are the high end of the Citrix SD-WAN product line. They are designed to accelerate sites with WAN links with speeds more than 155 Mbps, especially busy datacenters that communicate with many branch and regional sites.

Figure 1. Typical Use Case

A single SD-WAN WANOP 4000, 5000 appliance can support WAN speeds of up to 2 Gbps and up to 5000 XenApp/XenDesktop users.

For datacenters needing even more performance, multiple SD-WAN WANOP 4000/5000 appliances can be deployed as a load-balanced array using the WCCP clustering feature.

SD-WAN WANOP 4000, 5000 is recommended at the hub of a hub-and-spoke deployment, where smaller appliances are used at the spokes, whenever the link speed or the number of XenApp/XenDesktop 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 optimization for Data-Center to Data-Center replication. This optimization improves replication time and reduces bandwidth consumption.
