How many of you have been asked to size

a storage array over the past 2 years?

Audience Poll Question

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 ?

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|Reads per second

disk|Writes per second

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

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

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)
