File-level deduplication
34© Copyright 2011 EMC Corporation. All rights reserved.
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

VNXe FILE SYSTEM
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

Data Protection
37© Copyright 2011 EMC Corporation. All rights reserved.
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© Copyright 2011 EMC Corporation. All rights reserved.
• 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
Data Protection Storage Recommendations
39© Copyright 2011 EMC Corporation. All rights reserved.
Snapshots
40© Copyright 2011 EMC Corporation. All rights reserved.
• 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
The differences between Shared Folder & iSCSI snapshots
41© Copyright 2011 EMC Corporation. All rights reserved.
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

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© Copyright 2011 EMC Corporation. All rights reserved.
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© Copyright 2011 EMC Corporation. All rights reserved.
• 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

File Level Retention
51© Copyright 2011 EMC Corporation. All rights reserved.
VNXe File Level Retention – Enterprise (FLR-E)
• Enables adherence to good business practices • Provides for retention periods per file• Retention is managed on a per-file
basis
52© Copyright 2011 EMC Corporation. All rights reserved.
File Level Retention Workflow
• Not-locked files– Traditional non-FLR files
• Locked files (WORM)– Retention periods are set on a per-file
basis– Retention period is set to “infinite” if
left unspecified – Cannot be deleted, renamed, or
modified– Retention periods can be extended
• Append files– Protected files to which content can
be added but not modified or deleted
• Expired files– Files can be deleted after retention
time expires

File Level Retention Capabilities Tamper-proof clock:
Software clock maintained per FLR file system Maintains an additional clock that is separate from
the system clock– Changes in the system clock time cannot be used to fool the
file into “expiration”
Used for all File Level Retention time comparisons File Level Retention clock cannot be modified or
reset
Activity logging: Log is maintained in the File Level Retention logs
subdirectory Information for each event:
– Time of event (system time)– File with which the event is associated– Action (create, append-only file, etc.)– Operation being performed– The user ID of who performed or attempted the action
