BlueSAN Technology ezSAM	ezSAM Optimizer
Introduction	The Analyzer module of ezSAM provides the easiest and most efficient way to find out how effectively the storage space in different file servers and NAS systems in your computing environment is utilized. With a single click, you can discover, analyze and review the space utilization for all the file shares in your computing environment across multiple domains. The Optimizer module of ezSAM provides you a means to act on the unused and duplicate files that were identified by the analyzer. By using the Optimizer module, you can clean up or move out these files from the source file shares/folders to pre-designated places with a single mouse click.   Cleaning up your high value/high cost file shares of unused and unwanted files and data Tiering has never been easier.  Apart from the ezSAM family of products, BlueSAN Technology provides consulting services for various data center management projects of enterprise customers. In consulting engagements, for certain number of file shares (or certain amount of disk storage), BlueSAN provides the ezSAM Optimizer for free.
Required Steps:	Within ezSAM, a default location could be defined for moving out unused/unwanted files from all the managed shares/folders. Then one custom location could be defined for each individual managed share/folder for moving out the inactive/unwanted files.  Deleting unwanted files is also protected against once-in-a-while operational error where you delete some file inadvertently. A globally available recycle bin is provided to stage all the delete operations for a pre-defined number of days. In case you discover that some files has been deleted in-advertently, you can restore those files from this global recycle bin. You can clean up all your file shares of unused/unwanted files from a central console. The system provides you a mechanism to define and review the list of files that will be acted upon by the Optimizer. Once you have reviewed the file list for all the shares that are to be acted upon, you can submit all the clean-up and move activities one-after-another and then come back later to review the status of the operation. Steps to be performed once prior to using the Optimizer module: Define the default location for moving out the inactive files for all shares. Define the global recycle bin for holding on to the deleted files for a while. Steps to be performed for an Optimizer session on a share/folder for Inactive Files: Run the Analyzer in case the Analyzer was not exercised on the managed item recently. The user interface shows when the analyzer was run on the share/folder the last time. Reports are generated based on the globally defined "Storage Analysis Filters" for "Inactive files". If for this Optimizer session the globally defined filter is not appropriate, you can review and modify the global "Inactive Files" filter. (Note: in the current version of ezSAM, the global filter needs to be reverted back to its original content, unless the filter specification of this current session is to be used for all future Analyzer session on all shares/folders.) Perform the matching files activity. Review the report to see the matched files based on the "Inactive Files" filter. In the report, if it is found that there are files which could be moved out or deleted to make the managed share/folder more efficient then the list of these matching files are available in a text file that could be edited. Edit the matching file list to indicate which files to be kept and which files to be moved-out. In case all the matching files are to be moved-out, there is no need to edit the file list. Note that to keep editing less error prone, in a single Optimizer session either move or delete is allowed.  Define custom move destination in case the default move-out destination is not appropriate for the share/folder. Indicate if the defined move-out destination is to be used for this share/folder in all future Optimization session. Submit the move operation. After the move operation the Optimizer re-generates the report automatically. Review the report again to see if any files needs to be deleted. Go through the steps 6 and 7 to define a new list of files on which the delete operation needs to be performed. Submit the delete operation.  If needed, iterate through steps 3 through 11 to select files according to different size, type and age criterions until the managed share/folder is optimized to your satisfaction.  Steps to be performed for an Optimizer session on a share/folder for Duplicate Files: The steps for Optimizing a managed share/folder by cleaning up "Duplicate files" are same as in the case of "Inactive Files" described above.
