NetScaler SD-WAN 4100 and 5100 WANOP Appliances

Aug 31, 2017

Citrix NetScaler SD-WAN 4100/5100 WANOP appliances are high-performance WAN accelerators for busy datacenters. These appliances combines 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.

SD-WAN 4100/5100 WANOP WAN accelerators are the high end of the Citrix NetScaler SD-WAN product line. They are designed to accelerate sites with WAN links with speeds in excess of 1 Gbps, especially busy datacenters that communicate with a large number of branch and regional sites.

A single SD-WAN WANOP 4100/5100 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 4100/5100 appliances can be deployed as a load-balanced array using the WCCP clustering feature.

SD-WAN WANOP 4100/5100 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.
