Time Series Facility Database Recommendations

We recommend that you allocate a minimum of 3,000 cylinders for the Time Series Facility (TSF) database with the following additional recommendations for each discipline:

Note: These recommendations assume a retention period of 30 days and a cylinder size of 720 KB. If you lengthen the retention period or decrease the cylinder size, we recommend that you increase the database size.   

CA Chorus for Security and Compliance Management

• 700 cylinders

CA Chorus for Storage Management

• Lower bound (assumes 5,000 entity instances): 930 cylinders
• Upper bound (assumes 17,500 entity instances): 3,150 cylinders 

  entity instances

  Unique name of a dfSMS and non-dfSMS storage volume name, DASD volume name, catalog name, or data set group name that is registered in CA Vantage.

CA Chorus Infrastructure Management for Networks and Systems

• Lower bound (assumes 12 LPARs): 17,471 cylinders
• Upper bound (assumes 36 LPARs): 52,413 cylinders

Given that each site and configuration can vary significantly, use these recommendations as a general reference as you plan your TSF database sizing activities.

Best Practice for TSF Database Sizing

Use the initial allocation of 3,000 cylinders as a test space for determining the actual amount of TSF database space that your site requires. To do so, monitor the TSF database space for a few days to determine the appropriate TSF database size for your site. To increase your TSF database space, see Increase Data Set Space Allocations.

Note: You can also calculate the TSF database size using the algorithm that is provided in Calculate TSF Data Store Size.
