Reliability
CBS adopts a distributed mechanism with triple replicas. The system only returns a response confirming successful writing after ensuring that the data has been written to all three copies. The backend data replication mechanism can quickly create a copy through data migration or other methods if any one of the copies fails, always ensuring that three copies are available. This provides you with a secure and reliable data storage service. Data is stored across racks, achieving a reliability of 99.9999999%.
Elasticity
You can freely configure storage capacity and expand on demand without interrupting your business.
The maximum capacity of a cloud disk is 32 TB, and a single CVM can mount up to 20 elastic cloud disks as data disks, efficiently handling big data processing scenarios with TB/PB-level data.
High Performance
SSD adopts the NVMe standard high-performance SSD and provides up to 26,000 random IOPS and a maximum throughput of 260 MB/s per disk, achieving a combination of superior performance and ultra-high reliability.
Premium Cloud Disk helps you easily support high-throughput DB access on the business side.
Usability
The cloud disk can be managed and used through simple operations such as creating, mounting, uninstalling and deleting, to save the cost of manual management and deployment.
Snapshot Backup
You can create snapshots for cloud disks at any time to back up data, or quickly create cloud disks by using snapshot files to rapidly deploy business operations.
