Hi Andrey, For instance, i talked about deduplication to my manager and he was happy because less data = less storage, and therefore less costs . However, now the IT group of my company needs to provide to management board, a report of duplicated data found per share, and in our case one share means one specific company department/division. Bottom line, the mindset is something like :
* one share equals to a specific department within the company
* the department demands a X value of data storage
* the data storage costs Y
* making a report of the amount of data consumed by a department,
before and after deduplication, means that data storage costs can
be seen per department
* if theres a cost reduction due to the usage of deduplication, part
of that money can be used for business , either IT related
subjects or general business
* management board wants to see numbers related to costs, and not
things like "the racio of deduplication in SAN01 is 3x", because
for management this is "geek talk"
I hope i was somehow clear, but i can try to explain better if needed.
Thanks,
Bruno
