Elastic Volume Service (EVS) is an elastically scalable block storage device that provides high-performance and highly reliable block storage services for physical servers. eSurfing Cloud provides multiple EVS specifications to meet business needs in different scenarios, including distributed file systems, databases, and development & test environments.
l Users cannot mount EVS to some physical server specifications.
l Users can mount EVS types including Common I/O (SATA), High I/O (SAS), Ultra-High I/O (SSD), and Generic SSD (SSD) to some physical server specifications. Users can configure data disks with the desired I/O capabilities according to the business type of their physical server. For more information, see EVS Documentation.
