Metric	Value	Explanation

Metric	Value	Explanation
E tot vcap	40 GiB	This represents the virtual capacity of the VDisk.
E tot SEV save	17.88 GiB	This indicates the savings achieved through thin provisioning.
E % tot SEV save	44.71%	The percentage savings from thin provisioning.
Virtual Thin Capacity	22.12 GiB	The capacity after thin provisioning savings.
E tot COMP save	12.84 GiB	This indicates the savings achieved through compression.
E % COMP save	58.05%	This represents the savings from compression as a percentage of the thin-provisioned capacity.
E % COMP size	41.95%	This represents the overall savings as a percentage of the total virtual capacity due to compression.

Thin Provisioning Savings Calculation
Percentage savings	44.71%
Total savings	40 GiB * 44.71 / 100 = 17.88 GiB
Total Thin-provisioned Virtual Capacity
Calculation	40 GiB - 17.88 GiB = 22.12 GiB
Compression Savings	Given: 12.84 GiB
Compression Efficiency Percentage
Calculation	12.84 GiB / 22.12 GiB * 100 = 58.05%
Compression Savings Percentage
Calculation	12.84 GiB / 40 GiB * 100 = 32.1%
