Question Dell T7910 Workstation showing only one one drive (SAS1) ?

Hello,

Recently purchased a Dell T7910 workstation 2 Xeon CPU, 128gb RAM, added 4 SATA drives to default HDD tray (SAS 0). Purchased Dell Precision T7910 4x SAS 2.5" HDD Bracket Kit W80XH 470-ABHF 12G - Tested from ebay & added 4 SSDs(SAS 1).

In Dell T7910 workstation BIOS & in Windows 11 Pro, only 5 drives are showing, the other 3 drives I could not find them ?

Any help will be appreciate.

Thanks

You managed to install win11 on a dell 7910 ? what is your CPU ?
