I
didn't have any luck here. Posting this information for if someone
might find it useful (and - even better - for if someone might have
an answer and they can let me know the error of my ways!)
Using
information from this article -
How
are customer-level ratios and efficiency savings calculated?
- can we get close
to ActiveIQ Storage Efficiency ratios using NetApp OCI DWH data?
Also see:
How
are capacities calculated in Active IQ Digital Advisor?
Note: I use uppercase and lowercase characters for variables.
Variables and
Formulas
a
= Aggr Logical Used without Snapshot copies
v
= Logical Size Used by Volumes, Clones, Snapshot Copies in the
Aggregate
s
= Logical Size Used by Snapshot Copies
a
= v – s
R
= Aggregate Data Reduction SE Ratio
L
= Logical Space Used by the Aggregate
P
= Physical Space Used by the Aggregate
R
= L/P
A
= Aggr Physical Used Without Snapshot copies
T
= Total Physical Used
S
= Physical Size Used by Snapshot copies
A
= T – (S / R)
C
= Customer Efficiency Ratio without Snapshot copies
C
= Sum[a {for all aggregates and nodes in the cluster}] / Sum[A {for
all aggregates and nodes in the cluster}]
Problems I
Encountered
I could not find v
and s (thus I could not find a).
I could not find L
(thus I could not find R)
I could not find S.
