Or use dumb LSI SAS controllers (sas3442e-r with IT firmware loaded,

flexibility regarding md RAID and number of SAS/SATA drives attached.
The problem then becomes choosing the port expander chassis...
I know nothing about this topic :-(
Does the brand/model make difference in performance or reliability?
Do you have any recommendation? Even just one "known good"...
(These chassis are also quite expensive for what I can see.)
Up to 24 and maybe even 48 drives you can find monolithic solutions (one
chassis for mainboard and disks), but then not many brands make 16-24
ports controllers. LSI does not seem to make them, am I correct?
Also in a monolithic storage you only have to check that the controller
declares compatibility with the drives (sometimes there are indeed
issues) while for port-replicator based storage I don't know if I should
check the Compatibility List for drives against controllers, or for
drives against port replicator, or for controller against port
replicator...?
