Restoring Data Storage Predictability
Thoughts and Approaches on Managing Storage Performance and Capacity in 2017
Brent Phillips – Managing Director, Americas Brett Allison – Director of Technical Services

Agenda
• The Predictability Challenge
• Storage Background
• Storage Capacity Management
• Storage Performance Management
3
The Predictability Challenge
• What risky conditions exist right now across our entire environment? (rated metrics & exception charts for space, performance, configuration issues)
• Where do go next to see root causes? (intelligent drill downs)
• What related metrics are relevant to the context of this issue? (side-by-side mini-charts of related metrics that are clickable)
• What help is there to create a solutions? (built-in recommendations)
4
Predictability Requires Better Analytics • Lots of disparate data from:
‒ Hosts ‒ SAN Switches ‒ Storage Arrays
• Need to automatically: ‒ Normalize the data ‒ Enrich, additional calculations ‒ Correlate, interrelate ‒ Evaluate, good or bad? ‒ Easily navigate through it
IT Operations Analytics (ITOA)
"The use of mathematical algorithms and other innovations to extract
meaningful information from the sea of raw data collected
by management and monitoring technologies.”
Forrestor Research

Predictability Requires Better Analytics
• “..and other innovations…” ‒ Most useful ITOA innovation for storage is applying a
storage-specific type of artificial intelligence (AI).
• “Artificial intelligence is the science of making machines do things that would require intelligence if done by men” - Marvin Minsky 1968
• What could be done that there is no time to do?
• This is an example of why Applied AI is the #1 strategic technology trend according to Gartner

• Spend time on proactive storage management ‒ Not reactive fire fighting ‒ Not on maintaining the analytics infrastructure
• Allows for quick, easy Proof of Concept (POC)

Common Storage Capacity Forecasting Techniques
• HisS: Historical Swag or Order about the same as last year
• LRA: Linear Regression Analysis: Apply linear regression analysis to your usable capacity trend from the previous year(s). Continue growth line for some time in future.
• ABRBO: Burn rate/Burn out: Calculate average burn rate per day/month/etc. Divide capacity left by burn rate to calculate days until burn out.
• WARP: Wait and Reach out to vendor in Panic

Prepare: Validate, Normalize and Categorize
1. Validate 2. Normalize: EMC vs HDS
3. Categorize

Assess: Define the Criteria
1. Hardware Specific Storage System Throughput
2. Workload Dependent Storage System Response Time
35
Assess: Define the Criteria
36
Rate: Apply The Assessment Criteria
• (∑ 𝑟𝑟𝑖𝑖𝑛𝑛𝑖𝑖=1 )/n
‒ Where • r = rating at interval i • n = number of intervals
‒ Rating is always either • 0 = Value is less than warning • 1 = Value is greater than or equal to warning or less than
performance exception • 3 = Value is greater than or equal to performance exception
37
Visualize: Visualize the Rating
• How does color relate to the rating displayed? ‒ 0-.1 is Green ‒ >.1-.3 is Yellow ‒ >.3-3.0 is Red
• So out of 96 intervals: ‒ we need no more than 3 red or 9 yellow intervals to rate
green. ‒ Less than 28 yellow or 9 red intervals make the chart rated
yellow. ‒ Otherwise, the chart is rated red.
