1 Extending VMware Consolidation Benefits to Data Protection with Data Domain Achieving Efficient Data Protection for Virtualized Environments with Data Deduplication

2 Deduplication Storage Systems > 6,500 systems installed > 2,500 customers > 745 petabytes under Data Domain protection worldwide A History of Industry Firsts Data Domain: Leadership and Innovation First Dedupe NAS First Dedupe Volume Replication First Dedupe Volume Replication First Dedupe Gateway Largest Dedupe Array First Dedupe Directory Replication First Dedupe Directory Replication First Dedupe VTL First Dedupe Nearline Storage 2008

3 Data Domain: #1 in Deduplication Storage

4 Deduplication Defining a New Tier of Storage Storage 1.0 PRIMARYTAPE Storage 2.0 PRIMARY SATA & RAID TAPE Storage 3.0 PRIMARY SATA & RAID & DE-DUPE TAPE

5 ClientsServer Primary storage Backup/ media server Onsite Retention Storage Offsite Disaster Recovery Storage Retention/ Restore ReplicationDRBackup Archive to tape As required WAN Data Domain: Dedupe Simplified High-speed, inline deduplication storage; disk target for nearline applications Any leading backup software, archive apps, or custom nearline use All data types: structured and file Any fabric: NFS / CIFS / NDMP via Ethernet, or VTL via Fibre Channel Disk storage: Internal, or gateway to SAN array One dedupe infrastructure: remote office, datacenter with inline replication Onsite Retention Storage Offsite Disaster Recovery Storage Data Domain Archive Archive Application Server Drag&Drop Archiving

10 10 Challenge : Managing and Protecting Server Environments Storage Infrastructure and Bandwidth Costs Backup data > original data Replication of active system volumes for high availability is complex and expensive Replication of backup data is inefficient Data Center DR Facility Replicate 1TB Primary Data 10TB Backup Data Expensive HA Only Replicate Impractical

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 Virtual Machine VMware ESX Server System Inline deduplication vmdk normal backup process WAN replication vmdk 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 Izzy. Some years ago - never mind how long precisely - having little … Call me Ish. 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 Call me Ishmael. Some years ago - never mind how long precisely - having … Redundant Segment

14 Confidential14 Maximize Disaster Recovery Benefits 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 Virtual Machine vmdk files file and application data 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 WAN

15 Inline Deduplication for Optimized Time-to-DR Post-process DR restore point is usually obsolete Replicate During Backup DR-Ready Data Domain Inline Dedupe/ Replication Backup to Cache Dedupe & Replicate DR Ready Post-Process Dedupe VTL/Tape/Truck Backup to VTLCopy to Tape Truck to DR Site DR-Ready Backup Window Additional 2-3x backup time to get to DR Ready

16 Network-Efficient Replication for True DR WAN home DIR A Source: Remote Sites Destination: Data Center Hub Supports hundreds of remote sites % Cross-site Bandwidth Reduction 1- 5% True DR; lowers WAN costs; improves SLAs. Archive Data Backup Data DD120 DDX with DD690s DD580 DD120

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*** -- ESG ***Source: ESG Research Report, Data Protection Market Trends, January 2008 *Source: Gartner, Predicts 2008: Emerging Technologies Make Storage Hardware and Software More Effective, December 21, 2007 **Source: IDC, Top 10 Storage Predictions for 2008, December 24, 2007

18 Enable Simple and Efficient Data Protection for VMware Environments Requirement Greener IT Efficiencies Reduce floor space and energy consumption of servers by improving utilization Reduce floor space and energy consumption of storage with massive data reduction; average 40x-60x reduction of vmdk Files Comprehensive Data Protection and DR vmdk for easy server rebuild VCB for best protection on VMware Consolidate DR server equipment Disk-based performance and reliability Data Invulnerability Architecture Consolidated data protection for mixed physical and virtual systems 99% less bandwidth required for efficient network-based DR Dramatically improved recovery point and recovery time service levels Operational Simplicity Automated system recovery Application and system high availability through maintenance Eliminate tape dependence Reduce the cost of long-term data preservation to less than $0.35/GB – less than the cost of tape Simplify DR walk-through procedures Reduced Costs Proven 80-90% reduced operational Costs on Servers Proven 20x average reduced operational costs on storage and bandwidth
