This is the slide deck from the QoS webinar with the WHIR on 4/2/2013.

1. Advancing the way
the world uses the cloud
Unlocking the secrets of
guaranteed QoS in the cloud

2. What is true
Quality of
Service
(QoS)?
• The ability to deliver consistent
application performance regardless of
system condition or application activity.

3. Why is
true QoS
important?
• Enterprise comfort with cloud computing
continues to rise ($7.8B market by 2015)
• Current cloud infrastructure is unable
to support biz-critical applications
– Imbalance of capacity and performance
– Inconsistent performance/no QoS capability
– Data reduction techniques, if available,
negatively impact system performance
– Limited automation options reduce efficiency
– Limited scalabilty

4. Noisy
Neighbor
• One application consumes an unfair
amount of application resources
• Negatively impacts all other applications
and tenant performance

5. “Bolt-on” QoS
can’t solve
unpredictable
performance
• Prioritization: ranks applications in relation
to one another
– Cannot guarantee any app actually gets
the performance it needs
• Rate limiting: sets hard I/O limits
for individual apps
– No concept or capability for guaranteeing
minimum levels of performance
• Tiered storage: combines multiple types of
media to deliver different performance levels
– Performance for every tenant varies as algorithms
move data between media

6. What is
required to
guarantee
QoS?
Without all 6 core requirements for
guaranteeing QoS, a storage solution
cannot deliver consistency in
multi-tenant infrastructures.
– All-SSD architecture
– True scale-out architecture
– RAID-less data protection
– Balanced load distribution
– Fine-grain QoS control
– Performance virtualization

7. Requirement #1: All-SSD architecture
Deliver consistent latency for every I/O
HDD SSD

8. Requirement #2: Scale-out architecture
Linear, predictable performance gains as system scales

9. Requirement #3: RAID-less data protection
Predictable performance in any failure condition

11. Requirement #5: Fine-grain QoS control

13. Summary • Guaranteeing performance requires an
architecture with all 6 core requirements.
• “Bolted-on” QoS features fall apart at
scale – ruining any possibility of
performance guarantees.
• The cloud of tomorrow will find profitability
by running the high-performance
applications businesses depend on.
• By enabling true storage QoS, you can
achieve that today. Guaranteed.

14. The only storage architecture
for guaranteeing Quality of
Service in the cloud.
Period.
