How Should I Select Storage?

When you create a BMS, you can select one from the following storage types:

  • Elastic Volume Service (EVS): provides EVS disks of different QoS configurations to meet performance requirements in various scenarios.
  • Dedicated Distributed Storage Service (DSS): provides exclusive storage resources. You can create disks of different specifications as needed and attach them to BMSs.
  • Dedicated Enterprise Storage Service (DESS): provides dedicated storage devices for enterprises to help them migrate key services to the cloud.
