GIM/DATAMART sizing vs real storage usage

[borkokrz]

I'm using Genesys Sizing Estimator for GIM. I've some practice with DM estimator and I know that in  large environment (10000 agents, 1000 RP, 1000 VQ) numbers produced by this estimators are smaller than real Oracle database usage. The difference is about 20%. For smaller environments the difference is smaller and not that important, cause DM size is smaller.
Is there similar analogy for GIM estimator ? Predicted size for 12000 agents handling 750 000 calls per day is huge, so additional 20% space produce additional costs.

Hi,

actually is not that much of difference, if you are using the last 8.1 size estimator is actually very accurate, we made the estimator in our customer and so far everything is inside the idea (we do have a huge environment as you said). But, as usual, we did estimate the DB with 10% more space so we can have some time in case something goes wrong.

The trick here is to be very accurate in the number of everything the estimator said, if you use somethings a little (i.e. if you have 100 calls you put 110 calls) so it will actually make the calculation already with the 'extra' space.

also use the last GIM instalation, the last 8.0 versions have a few bugs that can make things go wrong.
