These reports have shown the net worth of electronic messaging within U S West and justify the existence of an electronic messaging group within our corporation. Redundancy Most larger corporate electronic messaging systems have multiple hubs that are used to store and forward electronic messages. If possible, it is recommended that these hub mach ines be located in different geographic locations. For example, U S West has hub machines at data centers in three states. If all of our hub machines were in the same data center, and that particular data center experienced a power outage, we would lose our electronic messaging services.
Alternate locations are key to any good disaster prevention and recovery plan.
Two years ago, one of our data centers lost power for a full day. We were still able to keep our messages flowing by rerouting them through our other two data centers. The idea of alternate routing also applies to the network. With redundant networking, you have multiple links of the same network type, such as multiple Ethernet lines. But should your entire Ethernet network go down, variable networking comes into play.
