Elastic Volume Service (EVS) disks are scalable virtual block storage devices designed based on the distributed architecture. You can create EVS disks on the management console and attach them to servers. A server can be an Elastic Cloud Server (ECS) or a Bare Metal Server (BMS). The method for using EVS disks is the same as that for using hard disks on physical servers. Compared with traditional hard disks, EVS disks have higher data reliability and I/O throughput capabilities. They are also easier to use. EVS disks can be used for file systems, databases, and system software and applications that require block storage devices.
