Yes, it does. Aruba VSF is a chassis virtualization technology. It operates creating a virtual backplane (so the backplanes are shared) across all chassis part of VSF.

I would like to create a VSF only for one module on each chassis.
You can't.
As you already undestood, the Aruba VSF is a chassis virtualization technology, not a chassis partitioning technology (I suspect chassis partitioning features, eventually coupled with IRF for chassis virtualization, can be found on some HPE FlexNetwork switches supporting Multitenant Device Context - MDC - eventually deployed with or without IRF).
We have Aruba VSF with two Aruba 5406R zl2, all LACP IEEE 802.3ad links work flawlessly...the only issue we have is that our license of VMware vSphere doesn't let us to use vDS (we are forced to use vSS) so our VMware infrastructure - actually - can't benefit of being connected to our VSF using LACP (it's a real shame).
