PRODUCT OVERVIEW

Fail to plan, plan to fail

Planning for your organization's future without taking into account how it will impact your storage requirements is like taking a trip through the desert without stocking up on water.

Eventually, you'll run out of storage resources. And when you do, apps and critical services won't work properly and you'll have to compromise or put plans on hold. Which is bound to displease your higher ups.

But unless you have comprehensive (and accurate) data on the amount of storage you're using today, working out your future needs will probably be about as useful as trying to guess the lottery numbers.

With sophisticated sensors for every type of storage device and support for most major manufacturers, PRTG gives you a wealth of real time and historical data to work with. That means your forecasts will be more accurate. Which means your plans (and the IT budget) will stay on track.

Storage Capacity Planning: FAQ

 

What is storage capacity planning (and how does it work)?

Storage capacity planning involves using historical data to work out your organization's future storage needs. The idea is to look at your organization's current storage consumption, growth trends, and what your higher-ups’ plans are, and use this data to calculate your future capacity needs. That is, the amount of storage required for your network (and your organization) to keep running smoothly.

How do you work out future storage requirements?

The most commonly used formula for storage capacity planning is:

Future capacity needs = Current storage consumption × (1+ expected growth rate)n + Buffer

where "n" is the number of years in the future you’re planning for.

First, take stock of your current storage consumption. How many storage devices do you have? How much disk space have you used up? And are there any bottlenecks, or apps or teams that use disproportionately more storage space than others?

Second, use this historical data to assess how much your storage requirements might grow. Factor in new projects, any plans to expand into new markets, and infrastructure changes such as new apps you might deploy and other developments that might affect the amount of data you’ll need to store.

Third, add a buffer, just in case your storage requirements turn out to be higher than expected or there are other issues, such as delays procuring the additional storage infrastructure. The buffer depends on what you’re going to store. If the data is business-critical, it’s a good idea to have a higher buffer, perhaps 20% or 30%. For less critical data, 5% or 10% might be enough.

How does PRTG help with storage capacity planning?

Well. Not to put too fine a point on it, but the capacity data you have at your disposal is make or break when you're working out future capacity needs. The more historical data you have (and the more accurate it is), the more accurate your predictions will be. But if you don't have much data, or it's hard to use because it's spread all over the place, you better add a very big buffer (which will drive up the budget and displease Colin from accounts).

PRTG's all-in-one network monitoring tool has sophisticated preconfigured sensors that can track the key metrics of every storage device on your network in real time. More importantly, once you start monitoring your storage, you can keep the data for as long as you need, giving you unparalleled visibility into your current storage requirements… and what your future needs might look like.

What is a sensor in PRTG?

In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, for example the traffic of a switch port, the CPU load of a server, or the free space on a disk drive. On average, you need about 5-10 sensors per device or one sensor per switch port.

We asked: would you recommend PRTG? Over 95% of our customers say yes!

Paessler conducted trials in over 600 IT departments worldwide to tune its network monitoring software closer to the needs of sysadmins. The result of the survey: over 95% of the participants would recommend PRTG – or already have.
