Before getting back with an informative answer, let me clarify something about your statement:
"supported through Software (supposing it is yet by Hardware) on these platforms as it happens on most HPE FlexFabric switch series?"
With 5900/5930/5940 you have to select a B2F or a F2B FAN tray. You can not tune the rotation by software (even if you have to
set the proper direction in CLI to be compliant to installed hardware).
Hello Vincent, you're correct.
I tend to be too indulgent (or too optimistic) with HPE FlexFabric's features&capabilities.
So, yes, HPE FlexFabric switch series need correct Fan Trays SKUs to be installed (Front-to-Back or Back-to-Front, mix is supported)...nevertheless there is a Comware command (fan preferred air-flow) used to reconciliate/reconfigure air flows directions with preferred ones, if I'm not mistaken...I should have clarified I was referring about that.
Thanks! that's OK (sorry for confusion), nevertheless my question for Aruba 8320/8400X is still valid...
And after checking, there is no such developpment plan for 8400 and 8320. Thanks anyhow for great ideas and comments.
The solution is use 8325 :-) there is a model with Fan Front to Back and another for Back to Front !
Gosh...would be nice!
The Aruba 8325 has Front-to-Back and Back-to-Front on both Power Supply Modules and Fan Modules...but I don't think they're exchangeable with Aruba 8320...and I really can't exchange a pair of Aruba 8320 for a pair of Aruba 8325...at least until Aruba will knock the door to leave my company a Xmas present! in ant case we are pretty much tied to (a lot of) 10Gbps NICs...so Aruba 8320 fits the bill.
If a customer has an 8325 B2F model can they just purchase the F2B fans to convert it?
Sorry for dragging up this old topic, are there still no B2F fans for 8320s and not planned or did this change?
I find it kind of mind blowing that that would not be a standard offering on kit like this (maybe I'm spoiled coming off Mellanox kit)

Unfortunately, none I'm aware of...and I've been in - sort of - "listening mode" for so long...and still I am.

Yeah, especially considering what is the current offering of Fan/PS airflow options for the newer Aruba 8325...I found it too (kind of mind blowing).
Still - after such many months - I don't understand what is blocking Aruba about that (Isn't the Aruba 8320 a DC switch? Doesn't it deserve such Fan/PS airflow options?).
months have passed and I already know that, probably, the answer you gave me was (and still it is) definitive...nevertheless looking at Edgecore offering (note the blue Fans B2F):
I still don't understand why Aruba wasn't able to provide Back-to-Front (Power-to-Port) Power Supply modules and Fans for its Aruba 8320...it would be an appreciated addition especially for users that deployed Aruba 8320 in a Campus/DC IT room where the cold/hot air isles are well separated.
