Costs and
Capacity Data
A lot of people get very nervous when you start to
discuss chargeback, as chargeback can be very complicated and often times is
not easily implemented.
You can start simply, without accounting, and it is
useful for both you and the users/departments to know exactly who is using what
from the total resources.
I’ve given an
example below which looks at the top 10 applications and how much of our total
storage they are using.
In this
instance the large chunk of lilac at the bottom traced back to IT and this is
something that you must also factor in – chances are with things like data
warehousing and testing IT are heavy consumers in their own right.
Simple chargeback schemes can encourage savings but be
sure to include the IT department in your calculations.
Multiple cost tiers for resources can encourage
further savings as high end storage carries a much higher cost.
In this scenario our client encouraged users of high
end storage to migrate to lower cost storage if it was not really necessary and
made significant savings.
Visibility
into the cost of consuming resources can be simple
In this
example the resource is shown as the turquoise bar chart and the actual cost is
shown as the dark blue line.
A simple chart
but very effective when talking to your users as you can start to talk in
monetary terms about the IT resources that they are consuming.
On Monday I’ll
be looking at creating a plan.
