Delete unused storage resources
From an embodied carbon perspective, it's better to delete unused storage resources so we are efficient with hardware and so that the storage layer is optimised for the task.
Delete any unused storage resource.
SCI = (E * I) + M per R
Software Carbon Intensity Spec
Deleting storage volumes will impact SCI as follows:
M: By reducing the total number of storage volumes required, the total embodied carbon is lower.
If we choose not to delete all storage resources because they might be needed in the future, then storing them permanently will take up a lot of unnecessary storage resources. A better solution would be to remove idle resources so that no hardware is wasted.
- It may reduce cloud bills, as reducing idle storage resources will cost less.
- We may lose access to data that might be needed in the future
