How much in-line compression do I get on AFF8080EX with Ontap 8.3.1

JohnChen — Wed, 04 Jun 2025 22:48:47 GMT

I have an AFF8080EX with ontap version 8.3.1.

I know that in-line compression is turn on by default.

I want to know how much in-line compression on my Netapp system.

What command can I use to check it?

Is this command correct??

Why do not I see it here?

dpsan2::> volume show -fields used, sis-space-saved, sis-space-saved-percent, compression-space-saved, compression-space-saved-percent -vserver Vserver1_a -volume r2mainb5_dr2prod1_data01_vol01
vserver volume used sis-space-saved sis-space-saved-percent compression-space-saved compression-space-saved-percent
---------- ------------------------------ ------ --------------- ----------------------- ----------------------- -------------------------------
Vserver1_a r2mainb5_dr2prod1_data01_vol01 5.90TB 0B 0% 0B 0%

Inline compression is not different from post process compression, so they are reported together. I think the fields you want are the "*-space-saved" fields.

Use the "volume show" command with these fields:

sis-space-saved
sis-space-saved-percent
dedupe-space-saved
dedupe-space-saved-percent
dedupe-space-shared
compression-space-saved
compression-space-saved-percent

volume show -vserver <SVM Name> -fields sis-space-saved,sis-space-saved-percent,dedupe-space-saved,dedupe-space-saved-percent,dedupe-space-shared,compression-space-saved,compression-space-saved-percent

EDIT: This is what one of my 8.3 systems returns:

vserver volume       sis-space-saved sis-space-saved-percent dedupe-space-saved dedupe-space-saved-percent dedupe-space-shared compression-space-saved compression-space-saved-percent

Ok...I know why I did not see it.

This is because I move my vols from 3220 to 8080.

The vol on 3220 does not turn on the inline compression.

After move to 8080, it did not show any saving for inline compression even though the vol on 8080 is turn on after moved.

Only new data will be compressed.

I created a new vol on 8080 and copy the data over and it works fine.
