After switching from an Intel Mac Pro (Trashcan) to a MacBook Pro (M1 Pro CPU), I can report the SANLink 2 10G SFP+ module works (Ventura 13.0.1). System was set up from a TimeMachine Backup of the Intel machine.
Only caveat at the moment: MTU size can't be set (stays on "automatic" and 1280; was manually optimized 8244 before); SANLink Utility is dysfunctional. From the server, read speed is good, writing speed is worse than before.
Anyone has a similar setup? Will there be a SANLink Utility for M-Series?
