10. Challenge: Managing and Protecting Server Environments

11. Challenge: Achieving the Data Protection Benefits of Virtualization
Virtualization enables simplified data protection and
disaster recovery through the encapsulation of
systems as files.
However, there is often a significant storage
requirement in order to capitalize on these data
protection benefits (i.e. image-level .vmdk backups)
Interestingly:
37% of organizations said the amount of data they need to protect increased after implementing server virtualization*
*Source: ESG Research Report, The Impact of Server Virtualization on Storage, December 2007

12. Solution: Using Deduplication to Protect vmdk Files
vmdk File Structure
At least 1 per virtual machine
Large, 2GB+ File
Unique structure includes many empty blocks
Data Domain Deduplication Benefits
Dramatic reduction in protected vmdk file size – average 40x-60x reduction
Disk-speed protection and reliability
Data Domain Replicator Software option provides network-efficient disaster recovery over existing networks

13. Variable-Length Segments Are Critical
Data Domain variable-length segment deduplication can identify change within each vmdk file
Fixed segment lengths cannot deduplicate beyond the first point of data change:
Call me Ishmael. Some years ago - never mind how long precisely - having …
Redundant Segment
Call me Ish. Some years ago - never mind how long precisely - having little …
Call me Izzy. Some years ago - never mind how long precisely - having little …
Variable-length segments maximize redundancy!
Call me Izzy. Some years ago - never mind how long precisely - having little …
Anchor Points

14. Maximize Disaster Recovery Benefits
Problems with Tape for VMware DR
Time required to write and read large vmdk files to tape
Burden and expense of managing tape rotation
Delay in locating tapes
Risk of lost tapes, failed tapes and lost data
Environmental impact of transporting tape media between sites
Eliminate Tape Dependency for Disaster Recovery
99% reduction in bandwidth required to replicate vmdk files
Rapid rebuild of virtual machines
Recover the entire virtual machine – system state, configuration, file system and application data
Enable system rebuild quickly and easily into dissimilar server equipment
Mix of physical and virtual systems all recoverable from Data Domain deduplication storage

17. ‘Green’ IT Initiatives Demand Efficient Storage
By 2012, de-duplication will be applied to 75% of backups.*
-- Gartner
IT managers looking to boost storage efficiency next year will
embrace online storage services, push de-duplication in the data
center and adopt solid-state disk drives to help fuel hardware
consolidation strategies and green initiatives.**
-- IDC
One-third of organizations with over 25TB of data cite that physical
footprint and energy efficiency has become a more a important
purchasing consideration of secondary storage systems***
