What is EonStor DS?
Software
SANWatch management suite
Included snapshot and volume copy/mirror functions
Optional thin provisioning and remote replication (via FC or iSCSI) functions
5
Local replication - snapshotsRead-only virtual point-in-time (PIT) data
copies, recording data state at a given moment
Uses Map to host so that the files accidentally
deleted can be restoredRollback source volume attacked by viruses
or hackers to its previous healthy state Benefits Space-efficiency Backup window as short as 10 minutes Granular recovery points
Flush agent available on MS SQL and Exchange

Local replication – Volume copy/mirror• Volume Copy
Immediately usable (Read/Write) point-in-time (PIT) full data copies within a single system
Uses - Support secondary
applications such as analysis, testing and backup
Benefits - Minimize performance
degradation and data corruption risk of production volume

Local replication – Volume copy/mirror• Volume Mirror
Sync or async full data copies within a single system
Uses
- Restart services within minutes after source volume fatal failure
Benefits - Highest data availability
users can achieve in single-system configuration

Remote replication • Sync or async full data copies across
systems Via FC or iSCSI host ports Support remote snapshot
- Used with async mode, take snapshot whenever synchronization session ends
• Uses Restart services in minutes after
disaster Centralize backup data Achieve continuous data
protection while offloading source system

Thin ProvisioningCapacity is dynamically allocated when
data blocks are written Cost benefits Delay equipment acquisitionOptimize capacity utilization: 30-
40% 80-90% Reduce power, space and cooling
expensesManagement benefitsExpand volume without downtimeSimplify capacity planning Eliminate individual volume
