3 With Data Domain Deduplication Storage Systems, You Can WAN Retain longer Keep backups onsite longer with less disk for fast, reliable restores, and eliminate the use of tape for operational recovery Replicate smarter Move only deduplicated data over existing networks with up to 99% bandwidth efficiency for cost-effective disaster recovery Recover reliably Continuous fault detection and self-healing ensure data recoverability to meet service level agreements 3

4 Deduplication Fundamentals 4

5 Data Domain Basics Easy integration with existing environment Control Tier Target Tier Disaster Recovery Tier Backup and Archive Applications CIFS, NFS, NDMP, DD Boost EMC Symantec CommVault IBM HP Veeam Quest Ethernet Virtual Tape Library (VTL) over Fibre Channel DD890 appliance Replication DD890 appliance 2U 2 to 14 ports 10 and 1 Gigabit Ethernet; 8 Gb/s Fibre Channel RAID 6 Up to 285 TB usable capacity with shelves 2 TB or 1 TB 7.2K rpm SATA HDD in shelf File system NVRAM N+1 fans and redundant, hot-plug power supplies 5

6 Network-Efficient Replication for True Disaster Recovery Lowers WAN costs; improves service level agreements DB Archive data Data Domain system 1 5% Flexible replication One-to-many Many-to-one Bi-directional System-to-system Cascaded Home Backup data Data Domain system 1 5% WAN Home Source: Remote sites Data Domain system 1 5% 95 99% cross-site bandwidth reduction Data Domain Global Deduplication Array Destination: Data Center Hub Supports hundreds of remote sites 6

7 DD Boost Software DD Boost Distributes parts of deduplication process to backup server or application clients Licensable software works across Data Domain portfolio Supports majority of backup software market EMC Avamar and NetWorker Symantec NetBackup and Backup Exec Speeds backups by up to 50 percent Process more backups with existing resources 20 40% less overall impact to backup server 80 99% less LAN bandwidth Enables Data Domain replication management from the backup application 7

8 Industry s Most Scalable Inline Deduplication Systems DD800 Appliance Series Global Deduplication Array DD Archiver DD600 Appliance Series DD160 Appliance Software options: DD Boost, DD Virtual Tape Library, DD Replicator, DD Retention Lock, and DD Encryption Speed (DD Boost) DD160 DD620 DD640 DD670 DD860 DD890 Global Deduplication Array DD Archiver 1.1 TB/hr 2.4 TB/hr 3.4 TB/hr 5.4 TB/hr 9.8 TB/hr 14.7 TB/hr 26.3 TB/hr 9.8 TB/hr Speed (other) 667 GB/hr 1.1 TB/hr 2.3 TB/hr 3.6 TB/hr 5.1 TB/hr 8.1 TB/hr 10.7 TB/hr 4.3 TB/hr Logical capacity TB TB PB PB PB PB PB PB Usable capacity Up to 3.98 TB Up to 8.3 TB Up to 32.2 TB Up to 55.9 TB Up to 142 TB Up to 285 TB Up to 570 TB Up to 570 TB 8

9 Deduplication Storage Evaluation Criteria 9

10 Methodology: Inline vs. Post-Process Deduplication INLINE Deduplication Before Storing POST-PROCESS Deduplication After Storing Deduplication Store Deduplication 3x disk accesses to shared store Other activities unimpeded Predictable Simpler The more processes, the more resource contention Copy to tape: Too slow to stream tape Recovery: Service level agreement predictability Replication: Poor time-to-disaster-recovery Deduplication: If interleaved with backup or restore More administration to fight these issues 10

11 Throughput MB/s Performance: CPU-Centric vs. Spindle-Bound 6,000 Data Domain Fibre Channel SATA Most deduplication vendors Number of Disk Spindles 11

12 Why Data Domain? Less disk to resource, less to manage CPU-centric deduplication Inline deduplication Simple, mature, and flexible Simple, mature appliance Any fabric, any software, backup or archive applications Resilience and disaster recovery Storage of last resort Fast time-to-disaster recovery (DR) readiness Cross-site global compression Data center or remote office 12
