  30. 30. Disaster Recovery Features <ul><li>Array-based replication with TrueCopy™ </li></ul><ul><ul><li>Industry-proven synchronous block based replication </li></ul></ul><ul><li>IP-based replication with IDR and IBR </li></ul><ul><ul><li>Easy to configure and policy-based asynchronous replication </li></ul></ul><ul><li>MetroCluster to ensure protection during site failure </li></ul><ul><ul><li>Active/Active stretched Geo-Cluster up to 100km distance </li></ul></ul><ul><li>Nearline solution </li></ul><ul><ul><li>Replication target, Tape replacement, Disaster Recovery site </li></ul></ul>

  32. 32. Replication Overview
  33. 33. IP Replication Overview <ul><li>Asynchronous data replication utilizing hardware accelerated snapshot technology </li></ul><ul><li>IDR—incremental data replication (file level) </li></ul><ul><li>IBR—incremental block-level (sparse) replication </li></ul><ul><li>Full or incremental copies </li></ul><ul><li>Automated scheduler (One time or recurring) </li></ul><ul><li>Preserves NFS and CIFS permissions, and ViVol/user/group quota information </li></ul><ul><li>File system and replication rollback </li></ul>TCP/IP
  34. 34. IP-based replication – IDR….1/2 <ul><li>Incremental Data Replication (IDR): </li></ul><ul><li>Supports policy-based asynchronous full and incremental file system-based data replication. </li></ul><ul><li>Administrators can schedule replication policies such as continuous incremental, periodic incremental and individual single full complete data replications. </li></ul><ul><li>Use Cases: </li></ul><ul><li>IDR is ideal in environments where there are many small files to replicate. </li></ul>
  35. 35. IP-based replication – IDR….2/2 <ul><li>Strengths: </li></ul><ul><li>Pricing: Included in firmware of High-performance NAS; most competitors charge for it </li></ul><ul><li>Ease of Use: Strong policy-based features for automating replication tasks. </li></ul><ul><li>Coverage: Asynchronous operation is possible over long distances. </li></ul><ul><li>Flexibility: Does not require NAS nodes to be clustered; Does not require NAS nodes to be identical at each end. </li></ul><ul><li>Weaknesses: </li></ul><ul><li>Not suitable for HA cluster failover—asynchronous operation guarantees there might be data loss in an HA cluster failover. Use TrueCopy with MetroCluster instead. </li></ul><ul><li>Performance can be an issue for large, active file systems. The more files change between replications, the longer a replication will take. Highly active, large systems can exceed the available time and/or bandwidth. </li></ul><ul><li>Changed object list can actually degrade performance on highly active file systems with many changes between replications. </li></ul>
  36. 36. IP-based replication – IBR <ul><li>Incremental Block Replication (IBR): </li></ul><ul><li>IBR leverages the advantages of file-level replication on a block-level </li></ul><ul><li>When data is modified, the modified blocks are replicated instead of the whole file. </li></ul><ul><li>Optional license </li></ul><ul><li>Use Cases: </li></ul><ul><li>File systems with large files. </li></ul><ul><li>Large database applications. </li></ul><ul><li>High-performance NAS deployed with iSCSI LUNs (which are seen as large files by the file system). </li></ul><ul><li>Strengths: </li></ul><ul><li>Efficient bandwidth utilization. </li></ul><ul><li>Weaknesses: </li></ul><ul><li>More resource intensive than IDR. </li></ul>
  37. 37. Leveraging array-based synchronous replication: MetroCluster <ul><li>Features : </li></ul><ul><li>Combination of clustering and replication technologies over metropolitan distances </li></ul><ul><li>Synchronous data replication utilizing very sophisticated TrueCopy replication technology </li></ul><ul><li>MetroCluster — Active/Active Cluster geographically dispersed up to 100km (62miles) </li></ul><ul><li>Benefits : </li></ul><ul><li>Survive site specific disasters with minimal interruption to mission critical applications and no loss of a single transaction </li></ul><ul><li>Improved operational resilience </li></ul>Cluster Interconnects Bi-directional TrueCopy Synchronous SAN SAN WAN
