Cloud for NAS services is now a reality thanks to new hybrid cloud models. Users can benefit from improved performance thanks to local flash performance and organizations benefit from cost effective cloud storage and breaks the endless storage refresh cycle. Register for our on demand webinar and learn: * The Challenges with NAS Refreshes * The Problems Continuing with On-Premises NAS * Five Reasons to Consider The Cloud

2. Our Speakers
Darren Miller is an early member of the ClearSky Data Engineering team, focused on system and
infrastructure performance and test. He has over 20 years of experience with storage systems and
storage solutions architectures involving databases, file, server virtualization, backup and DR, and
recently cloud integration.
George Crump is the founder of Storage Switzerland, the leading storage analyst focused on the
subjects of big data, solid state storage, virtualization, cloud computing and data protection. He is
widely recognized for his articles, white papers, and videos on such current approaches as all-flash
arrays, deduplication, SSDs, software-defined storage, backup appliances, and storage networking.
He has over 25 years of experience designing storage solutions for data centers across the US.

3. Level Set -
What Causes a
NAS Refresh?
● Out of capacity
● Out of performance
● Lack of features...

4. ● Lack of Mobility
● Lack of Distribution / Consolidation
● Data Protection can’t keep up with
Growth
● Vulnerable to Ransomware
NAS Hasn’t Kept Pace
with Users/Data Center

5. Workarounds Aren’t Working

6. ● Performance Bottlenecks
● Networking gets complex at
Scale
● Consume a lot of Data Center
floor space
● Lack of Cloud Integration
Scale-Out NAS

7. ● Even more complex
● Vendor troubleshooting
challenges
● Limited Cloud integration
Global File Systems

8. Cloud-Only
NAS ● NAS software in the Cloud
● OK for Cloud based applications,
but…
● On-premises Apps/User must
suffer from Cloud latency
● Even with Caching, misses
causes performance problem

9. ● Data Protection
● Ransomware Protection
● Data Distribution
● Reduction in Costs /
Management / Floor Space
Not Addressing the New Requirements

10. Five Reasons to Consider the Cloud

11. But requires the right architecture
● On-Premises with NAS Extension
● Cloud-Only NAS
● Cloud NAS with Single Tier
● Cloud NAS with Warm Tier
The Cloud CAN Deliver On-Premises Performance

12. ● Data is Synced to the Cloud in
near-real time
● Data is Snapshot and Replicated
to another Cloud region
● Recovery is instant
○ Instantiate the Snapshot version
you want
○ Refresh Caches (if necessary)
The Cloud Eliminates Data Protection /
Ransomware Concerns

13. ● Cloud is the central repository
● Maintains version control
● Data is distributed to Caches
and available to all locations
Data is Distributed

14. ● Data or Snapshots can be
presented to Cloud Compute
● Analytics
● Indexing
● Reporting
Data is Re-Purpose-able

15. NAS Refreshes
Come to an End ● On-premises Storage is All-Flash
that is stateless and easy to
upgrade
● Cloud storage expands to meet
Capacity requirements
transparently
● No paying in advance for Storage
● No Migrations

16. Summary
● NAS Refreshes have to come
to an end
● The Cloud is a good start
● But it requires the right
architecture
