Often people try to construct a business case to justify change.  This business case will attempt to quantify the impact of the change, and hence justify the value of carrying this action.  Estimating the impact of a change - before you make the change - can be tricky.     


This is where looking at historic trends can be useful.  Modeling how different scenarios might then impact on these trends is a powerful technique for assessing future change.     


SPACEWatch rapidly maps historic trends in storage use across the area you want to change - as well as letting you model change scenarios and see their predicted impact.


"Planning for change is about analysing historic trends and

modeling the future impact of different scenarios"


Traditionally, plotting historic trends has meant taking a snapshot in time, recording this, then repeating the exercise many times to slowly build up a trend.  SPACEWatch cleverly avoids this by analyzing the data in different ways.  The first time storage data is collected you have access to the full range of historic trend analyses.     
























Have I got a growing problem in storage use?  

Who's causing it?  What can I do about it?


Filter, expand or drill down on areas of interest - and because SPACEWatch is database driven the results are instant.  Take a look at the chart above - what happened on the 8th of March to cause this spike in storage consumption?  Now you can instantly find out where this happend - what types of files are involved - and who was responsible.     


Anticipate desktop virtualisation performance issues


If you're agressively expanding the number of desktops you've virtualised, you'll be facing a storage challenge.  Massive data centre loads are the norm - but what exactly is the challenge faced in your network?  


Use SPACEWatch to analyze the nature of the storage load and you can more accurately - and hence cost effectively - model the solution you'll need.  SPACEWatch provides bubble charts to map mutliple dimensions of data clearly - here it is obvious that recently updated files are mostly very small.  Drill down to instantly see which systems or users are generating this load.
































Model the benefit of change


Of course historic data is only one way to look at trends.  With SPACEWatch Exchange and IBM Notes Editions you can look at trends in mailbox use, for example.     


Trends become really interesting when you model change scenarios and look at their predicted impact.  In any strategy its useful to compare this against the option for doing nothing.     


With the SPACEWatch Scenarios tool you can do all this in one place - with rapid visual display of the outcomes.  In the example above we’ve modelled the removal of files that haven’t been used for at least three months, and compared it against doing nothing - all with one click of the mouse.     


















What if I remove unused files - based on
historic consumption of storage, what will the impact be?


SPACEWatch helps directly with your business case - it will also display the calculated cost benefit (or penalty) of your chosen scenarios.  Copy and paste the charts and results directly into your report and you’re “good to go”.

Look at historic trends in storage use - plan potential change.  See how much you'll save - or how much doing nothing will cost.

Why did storage consumption increase so quickly?  Who caused it, and where did it occur?  What were they storing, and are the files still in use?  SPACEWatch will tell you.

How will my desktop virtualisation perform with so many small files being constantly updated?  What applications are creating them?  SPACEWatch will let you work it out.

Perfect for your business cases.  This is how much you'll save in the future with this scenario - based on how your storage has been used in the past.  SPACEWatch works out the cost saving as well.
