The webinar discusses exposing myths about using flash storage for virtualization. It addresses whether all-flash or hybrid flash/disk arrays must be used, whether all flash storage is the same, if deduplication techniques are all equal, and if integration is identical across solutions. The presenters are an analyst from Storage Switzerland and a product marketing manager from Tegile who provide perspectives on balancing performance, capacity, and costs with intelligent use of flash and disk storage.

13. How Can Flash Be Implemented?
Legacy Approach
 Retrofit legacy arrays with SSDs
 Tiering s/w for passive migration
 Expensive & inefficient
SERVER
Server-Side Flash
 Flash storage in server
 High performance
 VMs in server islands
 No shared storage
 No HA

Scale-Out
 Clustered DAS servers
 SSD & HDD DAS
 Inconsistent performance
 CPU & memory shared across

Interim Band-Aid Solution Limited Use Cases Problems at Scale
Virtualization Dependent
Hybrid Arrays
 SSD for perf
 HDD for capacity
 Perf-capacity-cost
balance
 Managed Performance
For Most Workloads
All-Flash Arrays
 High performance
 Cost prohibitive for all
workloads
 Consistent

For High-Perf Workloads

14. Flash Myths
Separating Fact From Fiction
● You Must Use All-Flash
● Flash Storage is All The Same
● Deduplication is All The Same
● Integration is All The Same

17. All-Flash vs. Hybrid
Hybrid Arrays
 SSD for perf
 HDD for capacity
 Perf-capacity-cost
balance
 Managed
Performance
For Most Workloads
All-Flash Arrays
 High performance
 Cost prohibitive for all
workloads
 Consistent Performance
For High-Perf Workloads
Beware of options that only
address a limited number of
use cases.
All Flash & Hybrid storage
addresses a broader set of
workloads.

18. Flash Myths
Separating Fact From Fiction
● You Must Use All-Flash
● Flash Storage is All The Same
● Deduplication is All The Same
● Integration is All The Same

19. 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

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

20. Flash Myths
Separating Fact From Fiction
● You Must Use All-Flash
● Flash Storage is All The Same
● Deduplication is All The Same
● Integration is All The Same

21. 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

24. 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 SMBCIFS enables you to
consolidate storage
 You need choice to meet user expectations
and to drive consolidation
