Elastic Volume Service (EVS)

Elastic Volume Service (EVS) is a virtual block storage service, which provides block storage space for Elastic Cloud Servers (ECSs) and Bare Metal Servers (BMSs). You can create EVS disks on the console and attach them to ECSs and BMSs. The method for using EVS disks is the same as that for using disks on physical servers. EVS disks have higher data reliability and I/O throughput and are easier to use. EVS disks are suitable for file systems, databases, or system software or applications that require block storage devices.
