Why EVS?
A Range of Disk Options
Choose from EVS disks with Extreme SSD, Ultra-high I/O, General Purpose SSD, or High I/O. Whatever your storage demands, there is always a great solution at a reasonable price.
Elastic Scalability
Increase block storage space, even if the disk is currently in use. In just a few clicks, you can scale a system disk up to 1 TB and a data disk up to 32 TB, all without any disruption to your workloads.
Robust Security and Availability
Data on EVS disks is encrypted using industry-standard AES-256 encryption. Three copies of data are automatically created and stored on different nodes to ensure your data is always available.
Backup and Restore
Create backups for your EVS disks, so if data is ever lost or damaged, you can create new EVS disks or restore to the state as of the backup.
Real-Time Monitoring
Monitor disk performance using the free Cloud Eye service, which reports alarms and notifies you by email or SMS so you can handle the issues in a timely manner.
Data Sharing
Set up a shared file system or a cluster management system to allow concurrent access to one shared EVS disk from up to 16 cloud servers. Shared EVS disks are ideal for running clustered or high-availability applications.
