Hello, I am having 60gb Hard Disk, SCOM 2007 ACS Database Size is grooming and Giving Disk Space Issue. Please let me know the Best Practice to Avoid the Disk Space Issue. MNYash

Hi Planning and Testing in a sample POC environment is a good start to see how much data you are likely to collect. This can vary hugely across different companies due to different group policy settings and different retention and compliance requirements. "Having a 60 GB" hard disk is the probably not the ideal way to size or plan. Perhaps it would be more useful to consider the following questions and size your storage appropriately: What are your compliance requirements? What data do you need to collect and report on? How long do you need to keep that data?

Hello, Is there any option to delete the ACS Database and re-create the new ACS database for SCOM 2007 MNYash

Hi No. If you delete the ACS database then you delete all the configuration with regards to forwarders. If you wanted to follow this route then you'd need to disable ACS Forwarders, re-run setup on the ACS database to create a new ACS database and then re-enable the acs forwarders. You can change the grooming settings and let the ACS data be goomed: http://blogs.technet.com/b/kevinholman/archive/2008/03/07/acs-internals-part-1.aspx http://blogs.technet.com/b/jonathanalmquist/archive/2008/03/05/audit-collection-services-acs-grooming-not-working.aspx http://blogs.msdn.com/b/ericfitz/archive/2008/07/17/acs-event-retention-mechanism.aspx Please let me know the Best Practice to Avoid the Disk Space Issue. Best practice is to deploy a small environment which is representative of your environment, implement noise filters at the collector to reduce collecting unwanted events to the ACS database and then extrapolate your results (by servers and days) to determine what you expect the ACS database size to be. The MSFT sizing guide spreadsheet does not give guidance around ACS as there are just too many variables around each customers environment to come up with generic figures.
