Advantages

Advantages

Active-Active Storage

If a single storage device is faulty, data loss and service interruption will not occur, improving storage reliability. The computing performance of ECSs is not affected during the replication.

Data Consistency

Tenants can perform consistent active-active storage protection for all disks of one ECS or an ECS group.

Application Agnostic

Based on Infrastructure as a Service (IaaS), VHA supports active-active at the storage layer. Once a storage device fails, application data will be taken over and restored before the users feel it.
