Automatic live data replication is inherent within Joviam’s cloud architecture, without further user configuration. Blocks backing virtual disks are automatically distributed and replicated across the cluster upon creation, utilising dual redundant 40Gbit QDR InfiniBand (IB).
In contrast, server outages at traditional cloud providers have resulted in hours to days of downtime, with resulting business disruption and data loss from asyncronous backups that may or may not have captured in-flight transactions between the outage window and the last backup.
Within the Joviam platform, for every write to disk:
Node availability within the cluster is constantly monitored by our Software Defined Storage (SDS) system to ensure prescribed levels of data replication are consistently maintained.
If our SDS detects that a node is either having issues or is offline, data replication of the missing blocks to other nodes within the cluster begins immediately, thereby maintaining prescribed levels of data replication. When the original node is recovered, any changes made to storage are automatically updated and replicated – this entire process is entirely automatic, requiring no user involvement.
There are three main advantages to automatic live data replication over geo-redundant backups:
