XtremIO - Inline Thin Provisioning

• Optimal Block Allocation — No Waste

• Always thin provisioned

• No stranded storage

• 100% performance

• Perfect allocation granularity

XtremIO Inline Data Deduplication



Always on, inherent function



Scales-out



Truly inline, global, always on



Improves array performance



Lowers $/GB



Extends flash endurance

(12)

12/29

Lower effective costs, increase usable capacity

XtremIO Inline Data - Compression



“Always on”, inherent function



Compress unique data blocks

after De-Duplication and before

written to SSD



Lower $/GB - more usable capacity



Less CPU-Overhead

(13)

13/29

Total Data Reduction - Example

• 12 logical data blocks are written from the

host

• 8 redundant blocks will be reduced by the

Inline Deduplication so that 4 unique

blocks stay over. Dedup = 3:1

• 4 unique blocks will be reduced by

Inline Compression so that 2 phys.

Blocks stay over. Compression = 2:1

• Total data reduction of 12 logigal blocks

XtremIO Snapshots

• Direct readable/writable copies

• Snapshots are just like live production

Volume/LUN.

• Space-efficient, metadata-efficient

• “Redirect-on-unique-Write” method

XtremIO Balanced SSD Endurance

• XtremIO cluster active for 277 days under heavy write load

• 6PB written to array - 242TB per SSD!

• SSD endurance will never be a concern!

Inline Data at Rest Encryption



XtremIO data is protected and secure

–

Leverages self-encrypting SSDs with AES256

–

SSDs are unreadable if removed from XtremIO

–
