Global Data Vault is adding “WAN Acceleration” for our customers with physical servers – we already provide this for virtual environments and the results have been terrific – in some cases data is now moving 50 times faster. So now we’re adding it for all of our Cloud Disaster Recovery customers.
WAN Acceleration for physical servers is important because it enables data transfers to our data centers at speeds ranging from 5 to 20 times faster than conventional transfers. Conventional transfers rarely take full advantage of available bandwidth because the methods used to check for errors and acknowledge clean data packet transmission are not optimal for moving large amounts of data. Our WAN acceleration tools solve this problem – and thus improve the speed at which data is moved into our secure data centers – all leading to greater quality and higher reliability for our customers’ disaster recovery capabilities.
This picture shows the WAN acceleration setup for virtual environments:
The keys to this improvement are in two factors:
1) We keep track of data at a block level in a “global cache” and then simply do not resend data that is unchanged since the last backup and
2) We implement a communications protocol that is far more efficient for moving large amounts of data over long distances over the WAN.
We view quality in terms of RTO’s and RPO’s, which unlike most businesses is very quantitative. WAN Acceleration allows us to restore to more recent points and with faster restore times, keeping our customer’s data more current in our data center and locally.
