Block storageΒΆ

Table of Contents:

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.

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. 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.
