EonStor DS is designed to support mission-critical applications of small and
medium businesses (SMB), featuring redundant, hot-swappable hardware
components, CacheSafe technology and full RAID protection to deliver high
fault-tolerant capability. To protect data from even more critical threats,
EonStor DS also features local and remote replication capabilities. By
configuring the scheduler in SANWatch, users can automate replication tasks.
In the event of human errors or data volume failures, differential and full
copies of critical data sets can be leveraged to quickly recover data and
restart service. In addition, thin provisioning enables users to optimize
capacity utilization and minimize investments in large and underutilized
data volumes.
