Understanding Live Optics File Scan De-duplication & Compressibility Results Slides

Hi, I have run the scan against my local machine in order to understand how it functions & also get an understanding of the output before going to my client with it. However, I wanted to be sure I understand the output of the two slides.

Compressibility

Files tested for compressibility 64,439

Reported size of files tested 47.24 GB

Estimated compressed size of files tested29.78 GB

Estimated Compression 37.0 %

Est. post-compressed size of all files based on compressibility test and known compressed files 54.62 GB

De-duplication

Files tested for de-dup 141,607

Total reported size of files tested for de-dup 27.47 GB

Estimated size of tested files after de-dup 21.42 GB

Estimated de-dup 22.0 %

Estimated size of all files after de-dup 64.39 GB

From both above slides, it appears as though in this case... applying the compression & de-duplication technology would result in a larger, final data set. Do i read this correctly? Below are the fields I focused on.

• Did I interpret the output/results correctly?
• I assume this is simply a factor of the particular data set I scanned on my local PC?

Background:

I have a client that has quite a bit of VNX NAS & we are looking at refreshing those with UNITY, but also consolidating the number of systems. In order to help build a more compelling offer, we are also now considering the size of the actual hardware & what could be gained with efficiency technology & so a scan/assessment seems prudent in order to lower the risk associated with building a replacement system based on a capacity value dependent on efficiency technology.

Thank you
