Flash: A Must Have
Storage performance req’ts very different in
virtual infrastructure
VM I/O blender effect
Managing data growth is driving new economic
considerations
Infrastructure cost, floor space, power, cooling
Effective flash cost continuing to drop
The rise of new storage metrics: IOPS/watt, IOPS/TB
not $/TB

VM I/O Blender Effect
OS sequentializes each
individual VM’s I/O stream
Hypervisor multiplexes all
VM’s I/O streams together
Creates extremely random
I/O pattern
Spinning disks do not
handle random I/O well
Increased rotational
latencies and seek times
End result: each HDD
produces up to 10x lower
IOPS than before
Apps run more slowly

Flash-optimized array shipments will grow at a rapid rate
Hybrid array market grows at 21.1% CAGR through 2016 to $12.3B
All flash array market grows at 58.5% through 2016 to $1.6B
Hybrid arrays will become the new enterprise storage workhorse
By 2017 45% of shipping storage capacity will be flash-based
8
Does Flash Optimization Matter?
How you deploy it
DOES matter.
Flash is flash.
9
Flash Optimized Architectures
Look for a storage
architecture that has
been designed with flash
in mind.
Write minimization and wear
leveling
Garbage collection does not
impact write performance
Tiered storage environments with
caching and volume pinning
In-line data reduction that does
not impact performance
Thin provisioning, space-efficient
snapshots and clones
QoS controls for consistently
predictable performance in high
density storage environments
10
Other FOA Considerations
Scale out or scale up
VM-centric storage management
Dedicated storage administrators disappearing
Line of business rising to prominence
Dialing in to meet application performance req’ts
Manage virtual disks not LUNs
Industry examples (Tintri, VVOLs, etc.)
Maturity of enterprise-class data services
Thin provisioning, snapshot, replication, etc.

Flash Location Issues
Latency
Having compute near the data
Host vs network latencies
High availability/recovery
Data loss issues
Performance vs recovery trade-offs
Cost
Shared storage has higher entry cost
Application considerations
15
Choosing A Solution
PERFORMANCE
The “best” architecture
for any given environment
will be selected by trading off
these three considerations
COST
All Flash
or Hybrid?
CAPACITY
16
Business Benefits
Performance
Higher IOPS, lower latencies to meet SLAs
Flash can deliver 1000x the performance of HDD
Increased storage density
Ability to host more workloads increases value
Lowers infrastructure costs
Lowers floor space, capacity, and energy requirements
“3rd platform” CAPEX and OPEX profile
17
Deployment Recommendations
Consider flash for all new apps but especially…
Virtual infrastructure, databases, VDI
Consciously select deployment model
Host, array or appliance
Legacy or flash-optimized
Plan for increasing storage density over time
QoS, multi protocol support, balanced scalability
Consider scale-out architectures
As a long term approach to managing high data growth
Balance performance, cost, capacity in your choice
There is no “best” solution for all needs
