In this example, the cost of storing
and protecting the data of a department is to be calculated. The department has a File
System Server which stores data on RAID. This data is protected using SDLT
and disk media, and Quick Recovery scratch volume pools. A CommCell Console
manages the secondary storage and the CommCell is registered with the CommNet Server.
In order for the program to calculate the total cost of
storing and protecting the data of this department, the following steps
must be completed:
Estimate the cost per megabyte on each primary and secondary
storage entity. In this example, the following is estimated:
Primary storage:
RAID = .30
Secondary storage:
SDLT = .20
Disk = .15
QR Scratch Volumes = .10
Define cost categories for each primary and secondary storage
entity in the CommNet Browser. Follow the procedure
Add a Cost Category.
Define a billing entity for the department in the CommNet
Browser. Follow the procedure
Add a
Billable Entity.
For secondary storage costing, from a CommCell Console:
Associate the billing entity to the CommCell object which represents the data of the department that is
being protected. Follow the procedure
Assign a Billable Entity to a
CommCell Object.
View the cost categories from the
appropriate media or QR scratch volume pool properties, and change it, if necessary.
Modify the Cost
Category of the following:
Drive Pool
Disk Library
QR Scratch Volume Pool
Run data protection operations on the CommCell objects that are
being used by the department.
For primary storage costing, from a CommCell Console for SRM entities:
Select the cost category you defined for
the RAID storage entity and associate it
with the RAID storage entity. Follow the procedure
Assign a Cost Category to a
Resource.
Synchronize Cells with the CommNet Server. Follow the
procedure Synchronize
Cells.
Run the
Billing Charge Back Report. The Billing Charge Back Report gives you the total primary and
secondary storage costs for the department.
For data secured using SnapVault, there is no way to
determine the actual size of the data. Hence, the Charge Back report will not charge or consider SnapVault data.
