Seems Atto xtendsan 5.51 didn't survive the upgrade... Had to roll back. Anyone else have any luck?Thank you for verifying!
Actually, XtendSAN 5.51 is working on Big Sur, just need disable SIP in advance. But if you have installed it once before disabling SIP, then a clean install of Big Sur is needed otherwise the kernel extension approve pop-up will not shown in System Preference.Seems Atto xtendsan 5.51 didn't survive the upgrade...

I've tried this way before but din't work. I'll try again later. My MacBook Pro get battery changed today from Apple Store and I need to do a clean install. A little bit obsessive lol. It seems they've changed the keyboard to a scissors one, anyway feels better than before.Ok - so here's what you need to do to avoid having to re-install clean!
1 - Boot into recovery console (cmd + r), open up a terminal
2 - spctl kext-consent add FC94733TZD
(FC94733TZD is the ATTO team ID)
3 - Reboot regularly, open a terminal
4 - sudo /sbin/kextload /Library/Extensions/ATTOiSCSI.kext
(At this point, you'll get the pop-up telling you to approve the system extension. Do this, and then it'll ask you for a reboot)
5 - Reboot - and live the Big Sur dream!
