  1. NEXSAN E-Series™Best Backup to Disk

  2. Nexsan At-a-Glance • Established in 1999 • 28,000 systems installed in over 60 countries • Over 10,000 customers • Proven, Enterprise-class • 100% Channel • Markets Served Digital Surveillance Video & Entertainment Financial Local & National Government Law Enforcement Medical Scientific& Research Cloud Storage Transportation

  3. Agenda Backup and Restore Key Considerations • Backup to Disk vs. Tape • Primary Disk Storage • SAN-based vs. LAN-based Backups • The Role of Snapshots • Asynchronous Replication and Disaster Recovery • Backup Disk Storage • Best place to De-duplicate • Key Criteria • Nexsan’s Data Protection Software Partners Nexsan E-Series Disk Arrays • Capacities, configurations, features

  4. Disk vs. Tape • Disk • No single point of failure architecture • No human errors in loading / unloading tapes • Does not stretch • RAID • Always online • Asynchronous Replication to a remote site • Fast restores and easy to verify backups are correct • Tape • Can be a single point of failure • Human errors in loading / unloading tapes • Tapesstretch and shoeshine • Not online, slowing restores • Not automatically sent to a remote site

  5. LAN-based vs. SAN-based Backups • 1. LAN-based (no array-based snapshot) • Data takes the full round trip, bogging down application servers, the LAN, and the SAN Clients LAN LAN-based Snapshot Backup Agent Backup Software 1. Backup Server Application Servers SAN 1 Storage System 1 2 Array-based Snapshot 2. 2 Backup • 2. SAN-based (with array-based snapshot) • Data is copied within the disk array or across the SAN, with no impact to LAN or application servers

  6. Asynchronous Replication for Disaster Recovery Clients Clients LAN LAN Backup Server Backup Server Application Server Application Server Application Server Application Server Application Server Application Server SAN SAN Local Storage System Asynchronous Replication Asynchronous Replication Local Storage System Remote Storage System • Protection Against Site-wide Failure • Frequent snapshots are transmitted to target side • Snapshots may be mounted on target side • Backups may be performed at the target side • Good way to protect remote/branch offices • Failover / Failback to remote storage system • Pause / Resume, checkpoint restart, deduplication

  7. De-duplicate as close to the source as possible • Why not de-duplicate right before the backup disk? • Inline de-duplicating appliances either slow backups or are costly • Application servers and networks become bogged down transmitting information that likely will not make it onto the backup disks • De-duplicating appliances fragment data, which hinders restore rates • To test the validity of a backup, a full rehydration of data from the deduplication appliance to a free storage pool is necessary, hindering restore time objectives • Backups cannot be quickly tested to ensure they are correct with de-duplicating appliances Clients LAN Application Server Application Server Backup Server SAN Local Storage System De-duplicating Appliance

  9. Backup Disk Criteria • Reliability of Storage System • Storage Density / Rack Space • Modular Capacity Additions • Easy to Maintain Storage • High Throughput • Energy Efficient • Low Cost per Terabyte and Operation • Array-based Snapshots & Replication • Microsoft VSS Compliant & VMware Ready • Compatible with popular backup/restore applications

  10. Nexsan E-Series Disk Arrays Overview • Ultimate Reliability Storage • Hard drives individually stress tested • Then tested in the storage system • Anti-vibration Design™, Cool Drive Technology™ • Hot-swappable, redundant active components • Array-based Snapshots and Asynchronous Replication • Industry-leading Storage Density • E18: 18 drives, 72TB in 2U • E48: 48 drives 192TB in 4U • E60: 60 drives, 240TB in 4U • Active Drawer Technology™ • Administer storage with no downtime, heavy lifting or pulled wires • Active/Active Controllers • With dual RAID5/6 engines per controller • Up to 87% Energy Savings with AutoMAID® • Ideal for backup to disk or bulk storage scenarios • Leading Cost per Terabyte

  11. Nexsan E-Series: Industry-leading Design • Service drives without getting hurt • Drives remain active when drawer is open • Service system with no downtime • Increased reliability with less external wires to manage • Mount drives counter-rotating • Thick plates in chassis eliminate vibrations • Fans in front pull in air • Fans in back push out air • Air channels go straight through chassis • Even if a fan fails, air flows over drives • Variable speed fans with temperature sensors

  12. Nexsan E-Series: Industry-leading Storage Density • Rack Space Required for 240 3.5” Drives Nexsan E-Series up to ½ of the rack space U of Rack Space Required • Nexsan • E60s • Dell Compellent Series 40s • NetApp • FAS3240 • Dell EqualLogic PS6510Es • EMC • VNX5500
