13.17 Charging for storage usage Through the Data Manager for Chargeback product, Data Manager provides the ability to produce Chargeback information for storage usage. The following items can have charges allocated against them: Operating system storage by user Operating system disk capacity by computer Storage usage by database user Total size by database-tablespace For each of the Chargeback by user options, a Profile needs to be specified. Profiles are covered in "Probes" on page 527. Data Manager can directly produce an invoice or create a file in CIMS format. CIMS is a set of resource accounting tools that allow you to track, manage, allocate, and charge for IT resources and costs. For more information on CIMS see: http://www.cims.com. Figure 13-242 shows the Parameter Definition screen. The costs allocated here do not represent any real environment, but represent an example, based on these assumptions: Disk hardware costs, including controllers and switches. is $0.50 per MB Hardware costs are only 20% of the total cost over the life of the storage = $2.50 /MB On average only 50% of the capacity is used = $5.00 /MB used The expected life of the storage is 4 years - $5.00 /48 = 0.1042 /MB /month The figures used are for monthly Chargeback Chargeback is for cost recovery only, no profit
