At the beginning of March, we fully launched the
Hyper-V R2 failover cluster of nodes into commercial operation, on which all our virtual dedicated servers now work reliably. During the implementation, we experienced some problems as some of our clients
wrote about .

Now the service of renting virtual dedicated servers is based on the fault-tolerant cluster of Hyper-V R2 nodes. Cluster servers are built on the
HP platform
with 5500 series processors .

All data is stored in a storage area network (SAN) of the
Cluster Shared Volume type , which is quite rare in the hosting market.
Cluster features allow real-time transfer of virtual machines between cluster nodes (LiveMigration) to optimize cluster resource utilization and maintenance. In the event of an accident with one of the nodes, the virtual machines placed on it will automatically “rise” on the backup nodes.
The transition to such an infrastructure will improve the quality of the services provided and help us in the future to avoid the problems encountered by the authors of the article mentioned in the title.
ps We also decided to set special prices for new Hyper-V virtual machines optimized for CMS.
