How many of you have been asked to size
a storage array over the past 2 years?
Audience Poll Question

7. 7
Most Common Challenges in Sizing Storage
Oversized Array Way more powerful than what is really needed
Early provision for future
Add additional buffers for performance
Undersized Array Performance problems from day zero
Lack of visibility into future workload demand
Unbalanced Array
Capacity
Waste of money
Powerful backend that can’t be utilized
Add more disks despite enough capacity?

What Data Do We Need to Size Storage?
Clusters
Storage Array
Frontend ports – e.g
2 per Cluster
Storage Array
Backend
 Storage Frontend:
• Total IOPs & Throughput demand for each each cluster?
• What is the bottleneck of the frontend ports?
 Storage Backend:
• Total IOPs & Throughput demand for current environment?
• IOPs & Throughput my future array needs to support ?

Get the Right Metrics
Metrics to Interpret IOPs (Peak, Average),
Read IOPs(Peak), Write IOPs (Peak)
Disk Read/Write rates(Peak)
Total Disk Usage rates(Peak, Average)
Time Range At least 30 days

11. 11
Analyze IOPs to Size Backend
Peak IOPs: 73,944 IOPs
 3 key questions and what to measure/analyze:
What is the total IOPs across
my environment?
What are the Read and
Write IOPs?
What is the Read and
Write throughput?
disk|Commands per second
disk|Reads per second
disk|Writes per second
disk|Read rate(Kbps)
disk|Write rate(Kbps)

Gain True ROI from Optimizing Peak IOPs
Before IOPs analysis,
peak IOPs = 73,944
Peak found to be an Anti-Virus scan.
IT Admin spread Anti virus scan across
VMs to reduce peak IOPs
Peak IOPs reduced to = 49,303
Savings = 73,944 - 49,343
= 24,601(33%)
~= $300,000 in Enterprise Storage

In the last 6 months, how many of you
had to report on
Infrastructure Utilization
&
Unused Capacity?
Audience Poll Question

20. 20
Why is it Important to Report on Utilization, Risk & Waste ?
Am I meeting my SLAs?
How well am I utilizing
my infrastructure?
What does growth look
like & do I have enough?
• Reporting on Demand, Utilization & Risk
• Capacity bottlenecks now or in the future?
• Capacity available, used, remaining?
Monitor Demand,
Utilization, Risk
Reduce Operational Risk to Ensure Performance by

• How to optimize under utilized resources safely?

• Reporting on growth & forecast
• What has been VM growth trend?
• What has been my burn rate? Do I have enough?

Get the Right Metrics
16 GB- Total Allocated Capacity
2GB -What VM did not get (Contention)
8GB - What the VM got(Usage)
SQL VM
10GB- What the VM wants(Demand)
• Demand is What the VM wants:
Physical resources an object might
consume w/o constraints
• Demand = Usage (what VM gets)
+
Contention (What VM does not get)
• Allocation – Amount of a resource that the
user configures
• Use Demand for capacity & performance
if Demand > Entitlement
• May have performance issues
• May be undersized (‘Stressed’)
• Use Demand vs Consumed for Memory
Buffer The most a VM can get (Entitlement)
