By using Stingray Traffic Manager to load-balance and manage traffic across two or more clustered SharePoint servers, you can achieve dramatic improvements in capacity and reliability. Adding more SharePoint servers to your cluster will scale capacity linearly, and Stingray Traffic Manager’s application acceleration technology – offloading, caching, HTTP optimization – increases the capacity improvements further. When you load-balance traffic across two or more SharePoint servers, you make the entire service resilient to routine downtime (upgrades and reboots) and unexpected errors (such as hardware failures).
