Instructions
With SRM Chargeback Reporting, we can:
Charge for total storage consumption of an application.
Charge for storage, based on storage type, which can be block, file, object, or cloud.
In case of a block storage, charge per host, hypervisor, and virtual machine.
And for all of the mentioned, charge per service level.
Chargeback per storage type:
In case of block storage, cost is calculated per LUN capacity and is configurable within each SLA tier. It requires Solution Pack for Block Chargeback.
For file storage, it is calculated per file system and quota, for single SLA tier.
Object and cloud storage cost is calculated per bucket, and is collected from respective array as a metric. Object storage requires Solution Pack for Dell ECS, Atmos, and Centera, while cloud storage requires Solution Pack for Amazon S3
The block chargeback computations are performed automatically within the SRM component called chargeback-processor. It runs periodically, usually once per day, and generates chargeback metrics per Host/Hypervisor/VirtualMachine.
