  33. File-level deduplication

  34. VNXe FILE DEDUPLICATION Deduplication-enabled file system File A File A File A File B File C Compress and deduplicate file File B File A File C Stub A Stub A Stub B Stub C Stub C VNXe File-Level Deduplication and Compression Architecture • Deduplication processes: • Policy engine scans all production files looking for data that meets certain criteria: • Last accessed/modified time, minimum/ maximum size, file extension, directory • Or, files selected via API • Candidates are compressed • Duplicated files are removed by using SHA-1 or byte-by-byte data comparison • Stubs point to files in the hidden deduplication store • Deduplication is transparent to clients: • Process runs in the background • Files pre- and post processing look the same • Hidden deduplication store is a “working area” that is not visible • Reads decompress data in memory, not on disk • Writes are stored alongside deduplicated data • Modifying one instance of a file has no impact on other deduplicated instances Stub B File B Active file User visible area Hidden deduplication store

  35. VNXe File Deduplication and Compression: Data Modification • File modification does not cause file to be reinflated: • Allows targeting large files (Terabytes sized), and files that may show some level of activity while preserving user experience on access to these files • Deduplicated files can be modified while still preserving commonality: • New data is stored alongside old • File is either reinflated or reprocessed when new+old reaches logical file size: • Reinflated if selected for deduplication by the internal policy engine • Reprocessed if selected for deduplication via API VNXe FILE SYSTEM User visible area Hidden reduced data store File Data New Data File Data

  36. Data Protection

  37. VNXe: Takes Care of the Complexities of Data Protection • Problem: • Calculating the space required for data protection is complicated. It require formulas and an intimate understanding of underlying snapshot and replication technology. • Typical Result: • Data Protection either gets slapped together in a “probably should work” fashion, or a Professional Services engagement is required. • VNXe eliminates complexity by: • Integrating best practices for provisioning data protection reserve space • Easy to configure snapshot schedules and Application Consistent Snapshots • Simplified replication configuration and management

  38. Data Protection Storage Recommendations • VNXe provisioning best practices also cover Data Protection storage • Application specific best practices for data protection space. • Thin provisioning aware: Applications using thin provisioning will not require as much data protection storage. • Auto-adjustment of Data Protection space as your production storage resource grows

  39. Snapshots

  40. The differences between Shared Folder & iSCSI snapshots • Shared Folder snapshots use Copy On first Write (COW) • Snapshot creation and deletion is very quick • The space required for snapshots continues to grow as changes are made to the production volume • iSCSI snapshots use Redirect on Write (ROW) • Snapshot creation is very quick • Perfect for your latency sensitive applications • Snapshots don’t grow once created

  41. PFS files at 12PM PFS files at 12PM PFS files at 12PM PFS files at 12PM Example: VNXe Shared Folder Snapshot • Provides a read-only or read-write, point-in-time view of data • File system-level or iSCSI LUN view • Multiple snapshot versions – 96 r/o + 16 r/w • Typically has a 10% capacity overhead • Primary applications include • Simple user initiated file un-deletes • Efficient logical backup and restore • Copy on first write technology • Avoids fragmentation of primary FS • One side file data protection space for all file system snaps • Automatic extension of data protection space • Online full file system instant restore from any snap • Snaps can be deleted out of order Production file system .ckpt_PFS_3PM Single SavVol .ckpt_PFS_12PM PFS_3PM .ckpt_PFS_9AM PFS files at 4PM PFS_12PM VNXe Family PFS files at 4PM PFS files at 4PM PFS_9AM PFS files at 4PM SavVolextended Production file system Empty Space .ckpt_PFS_4PM PFS_4PM .ckpt_PFS_3PM .ckpt_PFS_12PM PFS_3PM • Production file system .ckpt_PFS_9AM • Snapshot • Logical point-in-time copy PFS files at 4PM Restore PFS to 12:00 p.m. snap PFS_12PM PFS files at 4PM PFS files at 4PM PFS_9AM PFS files at 4PM

  42. Snapshots Consistency Options • Crash consistent snapshots • VNXe provides the ability to create manual and scheduled crash consistent snapshots through Unisphere • Shared Folder: • Crash consistent snaps are acceptable • iSCSI: • Good for an emergency. Only applicable to applications with a single virtual disk

  43. Snapshots and Application Consistency • iSCSI Application consistent snapshots • Using 3rd party backup applications • Leverages the VSS framework for Microsoft Applications to create “Hardware Snapshots” for the application • Preferred Solution: Using the Application Protection Suite • Application protection Suite includes Replication Manager (RM) software • An RM agent runs on the host, which guarantees the applications using the storage are quiesced prior to creating snapshots • Leverages the VSS framework for Microsoft Applications • For applications with multiple virtual disks, Application Sets ensure consistency across all the storage resources • Exchange will automatically undergo snapshot consistency checks following the creation of the snapshot

  44. Data Recovery options • Snapshots • Shared Folder: User initiated recovery using hidden .ckpt directory or Microsoft “Previous Versions” interface • iSCSI: Snapshot promotion and revert performed using either Unisphere or RM Microsoft Previous Versions tab

  45. Replication

  46. Snaps Snaps FS/ LUNVDM FS/ LUNVDM VNXe Replication • Replication can be*: • VNXe to VNXe • VNXe to VNX • VNXe to Celerra (DART 6.0+) • Celerra (DART 6,0+) to VNXe • VNXe to VNXe fan-out & fan-in ratio 5 to 1 • Same technology for file & block Productionsite Disaster recovery remote site Network Network WAN • * See the “EMC Simple Support Matrix” (ESSM) for the VNXe Series, url: Simple Support Matrix EMC VNXe Seriesfor any prerequisites and requirements.

  47. Replication Frequency • Shared Folder replication driven from Unisphere • Manual synchronization • Automatic synchronization based on RPO (Recovery Point Objective) • iSCSI replication using RM • Schedule-driven synchronization frequency • Application consistency is guaranteed

  48. Anti-Virus

  49.  Œ  • Virus-checking request • Write/close orfirst read after new virus-definition file • Virus-checking signatures VNXe Anti-Virus Support • Shared bank of virus-checking servers • Can deploy multiple vendors’ engines concurrently • Virus-checking server only reads part of files • File access is blocked until it is checked • Scan after update • Scan on first read • Automatic access-time update • Notification on Virus Detect • Anti-Virus Sizing Tool • Runs over VNX Event Enabler VNXe Family User Virus-checking server

  50. File Level Retention
