Parking.ru - increase reliability. Cluster Startup for Hyper-V

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




Now the virtual dedicated server rental service is based on a failover 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 capabilities allow real-time transfer of virtual machines between cluster nodes (LiveMigration) to optimize cluster resource loading and preventive maintenance. In the event of an accident with one of the nodes, the virtual machines located 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. Details on the link.
