Cloud disks use a three-copy distribution mechanism, and the system ensures that data is written in three copies before returning a write successful response. If any of the copies fail, the backend data replication mechanism can quickly replicate a new copy by using methods such as data migration, ensuring the availability of three data copies at all times to provide you with a secure storage service. Data is stored across racks, and reliability reaches up to 99.9999999%.
You can configure the storage capacity freely, and expand the capacity on demand without business interruption.
The maximum capacity of cloud disks is 16TB. A single CVM can mount up to 20 elastic cloud disks as data disks, to efficiently handle TB/PB-level big data processing scenarios.
Premium Cloud Storage uses a cache mechanism to satisfy the normal business requirements of users. SSD uses NVMe standards and can provide 26,000 random read-write Input/Output Operations per Second (IOPS) on a single disk. This is suitable for scenarios with high requirements for I/O capability.
Ease of use
You can easily manage and use your cloud disks through simple operations such as creation, mounting, unmounting, and deletion, reducing both costs and business deployment time.
You can create a snapshot of the cloud disk to back up data at any time, and you can also quickly create a cloud disk by using a snapshot file, achieving rapid business deployment.
