Deploying Citrix SD-WAN WANOP appliances successfully is not difficult, but improper deployments can cause problems and provide inadequate acceleration. Be sure to select appliances with sufficient capacity for the links that you want them to accelerate. Product selection is also one of the factors to consider when deciding how best to fit the appliances into your topology.

The most basic deployment criteria are:

All packets in the TCP connection must pass through a supported combination of two acceleration units (Citrix SD-WAN WANOP appliances or Plug-ins).
Traffic must pass through the two acceleration units in both directions.

When these criteria are met, acceleration is automatic.

Acceleration Enhances Performance when Traffic Passes through Two Appliances

For sites with only one WAN network, these criteria can be met by placing the Citrix SD-WAN WANOP appliance inline with the WAN. In more complex sites, other options are available. Some, such as WCCP support, are available on all models. Others are available on certain models only. Therefore, the needs of a more complex site might limit your choice of appliances.

When evaluating your options, consider the importance of keeping various segments of your network up and running in the event that a device fails or has to be disabled. For inline deployments, Citrix recommends an Ethernet bypass card. This card, which is optional on Citrix SD-WAN WANOP appliances, has a relay that closes if the appliance fails, allowing packets to pass through even if power is lost or removed.

Redundancy is a consideration for all types of deployments. Citrix SD-WAN WANOP appliances offer different types of redundancy:

SD-WAN WANOP 4000/5000 appliances have dual power supplies.
SD-WAN WANOP 4000/5000 appliances have redundant disk drives.
Appliances can be used in high-availability mode (two redundant appliances with automatic failover). This mode is supported on all models.
