Hello
I would like to get the data reduced as much as possible. I'm trying to change the compression algorithm but A250 complains that zstd and lzrw1a are not possible on the platform. When I try to set the compression algorithm to gzip it complains that :
Ensure that GZIP compression is enabled on node "node-01". For further assistance, contact technical support.
I have the secondary compression type set.
The ontap is 9.11.1P3
Could someone please explain how is it with gzip and if it could help (is better than the default lzopro) ?
Thank you

lzrw1a compression needs a specific piece of hardware only present in A400 and FAS8300 (I think?)

After I got that zstd and lzrw1a are not supported on this platform I tried to find some support matrix on HWU but it looks like this information is not there. What about gzip? It says that it is not enabled on the node. I have not found how to enable it. It also says that I should contact technical support. So may be it is not that easy. Any other idea how to get the best possible compression? thank you

What is so bad with algorithm "lzopro" for you?
I assume NetApp configured it as default because it is a good allround algorithm.

I need to try something else to compare. The customer complains that they can get better results with gzip than we can deliver with all efficiency on Netapp.

AFFA250::*> volume efficiency inactive-data-compression modify -vserver * -volume * -compression-algorithm
lzopro zstd zlib
those 3 are the options for inactive data compression
default is lzopro , a better option that netapp support is pushing is zstd
i will post here a template how to enable it and some checks .
the main idea is that compression must be off to change the algorithm

i hope this helps

Thank you very much. I will try it.
