2. The BIG Picture of Virtualisation
DataCore’s storage virtualisation software enables you
to quickly and cost-effectively achieve a stable,
responsive and enduring storage infrastructure that
delivers:
• Extreme efficiency
• Improved performance
• Reliable data protection
• Flexible and efficient disk space provisioning
• Non-disruptive migration to new equipment
• Practical disaster avoidance and recovery

5. Infrastructure-Wide Functions

6. Automated Storage Tiering
 Define multiple storage classes (tiers) within a disk pool
 Data within a virtual disk migrates to appropriate tiers based on access
patterns
 Tiers can be defined on disk performance and capacity
 Storage Profiles alllow the allocation and migration preferences amonst
tiers
 Can be used with already existing disk pools

7. Auto Tiering – How it works
 Monitor sustained I/O behavior across groups of disk blocks
(chunks)
 Compare access frequency against average for each tier
 Promote or demote chunks to most suitable tier
Tier 1 Tier 2 Tier 3

moves up a tier moves down a tier

8. Virtual Disk distribution within a pool
 Each Virtual Disk has a Storage Profile assigned
 Storage Profiles define tier preferences

9. Sophistication without complexity

10. Addresses the 3 Major Tasks of Infrastructure-wide Storage
Administration
+Adaptive Caching
I/O acceleration
+Load Balancing
Heterogeneous Devices
+Built in Best Practices
Auto –Tuning/Pathing
Protection at 3 Levels:
1. Data Layer Protection
Continuous Data Protection
+Thin Provisioning
2. Local Failure Protection
Space Efficiency/Reclamation
HA / Synchronous Mirroring
+Auto Tiered Disk Pooling
3. Remote Disaster Protection
Heterogeneous Device types
Asynchronous Replication

11. DataCore Makes HA-NAS Practical
Business Continuity & Performance are essential today:
• Resilient Storage and Performance requires ‘Enterprise’ NAS
(also known as NAS Filers, Filers or File Shares)
• But, current systems are lacking or too expensive to deploy
DataCore’s compelling software advantages apply to NAS
DataCore is adaptable, portable and enduring software infrastructure, therefore:
• No additional software required
• Utilizes existing DataCore features and Microsoft enterprise server built-in capabilities to
achieve HA NAS clustered file shares
• No additional server hardware required
• Simple to configure DataCore and Windows Cluster server to be shared on the same physical
machines
• DataCore’s existing feature set easily applies to NAS
• Adds Non-disruptive Auto-failover and Failback HA capabilities
• Adds performance acceleration, space efficiency and scalability to empower Microsoft
clustered file shares

12. Why DataCore for High Availability NAS
• Insulates your business from storage (and filer) downtime
• Prevents storage from becoming a single-point-of-failure
• Empowers Microsoft clustered file shares
• Accelerates performance, improves disk utilization & scalability
• Cost-effectively leverages existing infrastructure capabilities
