Expand Application Acceleration

Application Acceleration : Microsoft Exchange

Compass enhances Exchange with:

• Up to 2,500% Exchange acceleration over the WAN
• Works with Outlook caching enabled
• QoS to enable continuous replication capabilities
• Protocol acceleration to mitigate latency and fill the pipe
• Transparency to simplify infrastructure integration

The Compass approach to Exchange optimization is one where the best parts of Microsoft functionality are used when possible. For example, starting with Outlook 2003, Microsoft enabled a cache mode function that does a fantastic job at mitigating the performance hit of MAPI over the WAN. The Compass solution recommends continued use of this secure performance optimization, so only new traffic needs to traverse the WAN (and Compass’ predictive algorithms can easily handle this first-pass traffic). On the other hand, by disabling Exchange’s compression of MAPI traffic, allowing this to be handled by the award winning Compass technology, the Exchange server resources are immediately freed up, allowing better scalability and server response times.

Synchronization and exchange of data between Exchange servers is critical to reliability and scalable operations. Using mostly SMTP protocols between Exchange servers, in addition to compression, Compass is able to greatly reduce transfer times by use of protocol (TCP) acceleration. Particularly when these Exchange servers are in different datacenters, Compass’ QoS ensures that Exchange’s continuous replication capabilities has the bandwidth it needs, without adversely impacting the performance of other application sharing the WAN.

Combined with Microsoft Exchange, Expand’s Compass platform ensures that the communications infrastructure is up to the business and technical challenges that face a distributed workforce. By transparently optimizing Exchange traffic to the branch office and between datacenters, IT organizations are able to reliably achieve both efficiency and productivity, while supplying the business with anywhere and anytime access to vital business communications.
