Block storageΒΆ

Block volumes are similar to virtual disks that can be attached to any compute instance, in a region, to provide additional storage. They are highly available and extremely resilient. You can create copies of block storage volumes for rapid recovery and rollback situations.

Our block storage service is provided by a fully distributed storage system, with no single points of failure and scalable to the exabyte level. The system is self-healing and self-managing. Data is seamlessly replicated on three different servers in the same region, making it fault tolerant and resilient.

The loss of a node or disk leads to the data being quickly recovered on another node or disk. Additionally, the system runs frequent CRC checks to protect data from soft corruption. The corruption of a single bit can be detected and automatically restored to a healthy state.
