Key #1: Multi-Level Capacity Management
Storage capacity planning is a multi-dimensional challenge that requires a multi-level approach. All too often, companies either overestimate their storage needs, which leads to overspending, or they make simplistic estimates that frequently lead to unplanned purchases due to inaccurate forecasting. The only way to accurately track your growth trends and forecast precise outcomes is to collect data at all levels of the organization.
Unfortunately, most organizations don’t analyze storage at each level, primarily because it is difficult, time-consuming, takes time away from other critical responsibilities, and sometimes the level of detail is simply unavailable. Instead, in most cases, a business will only track storage usage and growth trends at a high level, but this limited analysis is bound to cause businesses to miss seeing crucial trends.
Imagine running a high-level storage capacity report that shows 300 terabytes available across your storage environment, and assume that for your business, that is more than enough space for your next project. Except what you didn’t see was that space is split between your two data centers, and then it’s further divided across a number of arrays, and finally, it’s even further divided across multiple pools. In reality, your 300 terabytes are fractured storage, and there isn’t enough of it in one place to handle the workloads that you need.
To avoid this vulnerability, VSI helps enterprises track storage capacity at all levels of the organization, including:
While everybody can do capacity management at some level, VSI offers an automated data collection process and consistent reporting at four levels of capacity management. This multi-level approach provides IT leaders with reliable data, allowing them to forecast precise outcomes and enable efficient and smart storage capacity planning.
Key #2: Forecasting Models
Forecasting helps IT leaders both plan more precise outcomes and avoid unexpected problems. VSI provides IT leaders with modeling capabilities that help them plan in advance, evaluate solutions, negotiate purchases, and reduce budget costs.
There are three primary forecasting models:
- Weighted average
- Simple linear
- Customer selected
The weighted average builds on a customer’s most current data. This model looks at the last six months, using weighted averages and weighing last month more than other months. Most businesses don’t think they are growing as fast as they are, and they often think they have more time than they do to make storage decisions. The weighted average forecasting model can often be the most representative of a company’s current situation.
The linear growth forecasting model utilizes simple averages. It pulls from a limited sample of data to predict future growth trends.
The customer-selected growth model can offer variable time frames and can also shrink and expand historical trending. This model can be adjustable for business changes.
Each of the three forecasting models can be used to clarify capacity and growth assumptions. By applying one of these forecasting models, businesses can plan for various storage needs, including new workloads coming in or leaving, new applications, and performance requirements.
Better forecasting tools make it easy for IT leaders to be proactive about storage capacity requirements. IT leaders can also change their forecasting model to test for different results.
Key #3: What-If Scenarios
Businesses are good at knowing what their future workloads will be, but they often don’t see the long-term effects of adding data. Don’t get stuck repeating short-term solutions. Beyond forecasting for your current environment, forecasting can also help with what-if data. VSI allows IT leaders to model applications or predictions for completely different scenarios than what data currently exists.
By being able to accurately predict outcomes for these what-if scenarios, VSI helps IT leaders select capacity management solutions that will last.
By utilizing these three keys to capacity management, VSI helps IT leaders allow for better planning, tracking growth trends, forecasting precise outcomes, and avoiding unnecessary, reactive purchases. Successful capacity management is crucial for businesses to maximize their data storage resources, as well as reducing costs and improving efficiency. Schedule a demo to talk to a VSI data expert.
