Minimal StarWind Virtual SAN DR setup is just one virtual machine on the DR site since it is a pure software solution, which is extremely cost-effective. It works on any hypervisor
that runs on existing general-purpose hardware and in private or public Cloud (e.g. Amazon or Azure
). This solution will not affect performance of the whole system since the DR site does not require high performance. StarWind
implements replication as asynchronous, putting it to the background and using snapshots as the source. As a result, StarWind eliminates the performance and space over-provisioning problems typically encountered with traditional DR replication solutions.
Overload of the WAN data link is eliminated by combining StarWind space reduction technologies — deduplication, compression, snapshots, change block tracking, etc. As a result, there is a significant decrease in the amount of actual data transferred. Due to the reduction in WAN requirements there is no need to buy high-cost data links.
Data Integrity. StarWind snapshots technology restores to the latest integral point of data even if corruption occurred on the primary and DR sites.
