Writing data to EMC Centera has long been considered a “black box” approach, because data is stored as objects with associated Content Descriptor Files (CDF), rather than being stored in a native file format using standard folder structures that users are accustomed to browsing with Windows Explorer or other directory management tools.
As a result of this black box approach, files and directory structures are not directly viewable to client workstations,so users and IT staff have very little visibility into how much data resides on the device, if any data has reached its retention period, and a number of other unknown factors regarding how the data was organized, classified, and written to their Centera.
In an effort to help organizations achieve better visibility into their Centera environment, we offer a Centera Assessment service that produces a report with tables and graphs depicting the following information:
Application Summary – an informational table containing statistics for every Virtual Pool defined on the Centera. Includes pool name, total object count, total data volume in GB, and the time/date stamp of the oldest and newest C-Clip
Ingest History – a line graph that shows the total amount of data in GB written to Centera on a monthly basis since the first C-Clip and object were written
Cumulative Capacity – a line chart that shows the cumulative volume of data in GB written to Centera on a monthly basis, with a supporting table that shows ingested object count and data volume for that month, and cumulative ingested object count and data volume to-date
C-Clip Age Summary – a bar graph that shows the total amount of data in GB written to Centera annually for each year since the first C-Clip was written, with a supporting table that lists C-Clip count and data volume that matches the associated bar graph
File Type Summary – pie charts that show the total file count and total data volume in GB written to Centera, summarized by file type (PDF, TIFF, NSF, TXT, etc) with a supporting table that lists the same information in tabular format
Object Retention Summary – an informational table that lists the total object count and associated data volumes for objects that are expired, not expired, and on legal hold
Object Retention History – a bar graph depicting the total data volume in GB that is retained, not retained, and expired
