 Requires costly High Bandwidth Low Latency Links

 Inability of storage systems to fill WAN link due to

latency/packet loss issues

 Need to increase the distance of the disaster recovery

site

Challenge

 Device Mode purposely designed for DC-to-DC

replication and backup optimization

 Optimized for High Speed Links, Low Connection

Count, and Low Fan-out

 Supported on DC devices WAE-73x1

 Branch/DC and DC/DC managed from same WAAS

Central Manager (CM)

 3rd party data replication solutions support
