Axxana is a company that is attacking a very difficult problem. In the case of Axxana one could argue it is tackling the toughest problem in computer science – that is, the speed of light. Despite the fast movement of bits through computer systems, they can’t travel fast enough to overcome the latency involved when moving data at distances over about 200 kilometers– a common technique used to avoid certain catastrophic disasters. As a result, when organizations protect data from disasters by storing data in two places at distances greater than 200 km (i.e. asynchronous distance), the data that is written incurs a small lag time between the moment the data is written locally and the time it takes to finish the second write remotely. This lag, although small, can result in data loss during a disaster. Certain applications require zero data loss and as a result, very expensive architectures involving three data centers are deployed to mitigate this risk.
Axxana convieved of a way to eliminate the added expense of a third data center by creating a virtually industructable ‘black box’ – like an airplane black box – that houses the small amount of data that is lost in flight traveling at asynchronous distance when a disaster occurs. In the event of a disaster, the data can be retrieved from the black box and re-synchronized with the remote site in a matter of hours, resulting in zero data loss.
