WAFS products support the efficient exchange of data between remote locations over a WAN link, allowing remote offices to access data from a data center as if it were local. WAFS can typically support a wide range of applications across virtually any WAN link. WAN optimization is often (but not always) included with WAFS products, using compression and data reduction techniques to reduce bandwidth requirements, ease latency or make better us of existing bandwidth. The following product snapshots highlight key specifications for a cross section of WAFS and WAN optimization products intended for small, medium, and large organizations. The following products were selected based on input from industry analysts and SearchStorage editors, and vendor's specifications are current as of November 2007.

These specifications are periodically updated, and vendors are welcome to submit their updates and new product specifications to sbigelow@techtarget.com.
