Distributed backend architecture, 3-copy redundancy, and 99.9999999% durability.
Up to 5,000 IOPS and 150 MB/s of throughput for a single EVS disk.
Up to 32 TB for a single EVS disk, and online disk capacity expansion.
AES-256 encryption, secure and agile, with no application awareness.
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.
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.
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.
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.
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.
This document describes basic concepts, functions, key terms, and FAQs of EVS disks and provides instructions for quickly applying for and using EVS disks.
This document describes application programming interfaces (APIs) of Elastic Volume Service (EVS) and provides API parameter description and example values.
