Exposing The Myths of Flash Storage For Virtualization
Join Us as We Expose These Flash/Virtualization Myths
1. You Must Use All-Flash or Never Use All-Flash
2. Flash Storage is All The Same 3. Deduplication is All The Same and All You Need
4. Integration is All The Same

Chris has been instrumental in the success of some of the storage industry’s most key companies over the past 10 years. At Tegile, Chris is developing the product marketing strategy and competitive analysis portfolio. Chris’ background includes Sun Microsystems, EMC and Dell/Compellent where he held various roles in technical marketing, sales engineering and competitive analysis. Chris received his BS in Management Information Systems (MIS) at San Jose State University.
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 25 years of experience designing storage solutions for data centers across the US.

Agenda
• Flash and Virtualization - The Perfect Match
• The Flash and Virtualization Myths
• The Flash Reality
• A Flash Solution
• Q&A

Flash Acts as theShock Absorber
And the Flash Myth is Born

How Can Flash Be Implemented?
Legacy Approach

Beware of options that only address a limited number of use cases.
All Flash & Hybrid storage addresses a broader set of workloads.
Flash MythsSeparating Fact From Fiction
● You Must Use All-Flash
● Flash Storage is All The Same
● Deduplication is All The Same
● Integration is All The Same
Not All Flash-Based Arrays Are Created Equal
Periodic data migration across tiers Policy-based or ad-hoc migration Admin mediated Coarse level of granularity for migration
Legacy “Bolt-on” Tiered Storage Next-Generation Flash Storage
Intelligent Caching Real-time Fine-grained Specific Locking
Performance Layer
CapacityLayer
Implementation Differences
Type of SSD Most arrays use lower-end cMLC – endurance concerns
Caching Most arrays use flash only for caching reads Optimizing metadata access is important
Data Reduction Some arrays only provide compression – no dedupe Some arrays only dedupe data in SSDs, not HDDs
Flash MythsSeparating Fact From Fiction
● You Must Use All-Flash
● Flash Storage is All The Same
● Deduplication is All The Same
● Integration is All The Same
Drive Down Storage Costs with Data Reduction Inline compression and deduplication can shrink storage footprint up to 90%
Leverage Flash for Meta Data and run data efficiency on flash and disk Eliminates the flash capacity can be free statement
Redundant OS images are reduced to a single instance and stored in flash
Save on rack space, power/cooling, storage sprawl

Shared StoragePros/Cons
Networking and Scale Issues
Inconsistent andNot Cluster Ready
Shared Storage Considerations
Shared Storage Protocols
Fibre Channel may make your deployment too expensive
iSCSI and NAS may not meet your IOPS needs
An array providing SMB\CIFS enables you to consolidate storage
You need choice to meet user expectations and to drive consolidation
