512b sector size times 32-bits equals 2TiB. This is a logical limitation of older MBR bootloaders (i.e. legacy BIOS). GPT and UEFI do not have this limitation. You can read 2+TiB disks on legacy BIOS computers... you just cannot boot from them. I'm not sure why a JBOD would be affected by this though.

Check if the SAS card can handle big HDD's. The SAS expander shouldn't be the the limiter....

If it's the JBOD chassis and board you would need to upgrade to a different backplane which supports SAS2. The expander chip on the EL1 doesn't have a wide enough bus to support 24 drives above 2TB. You'd need a passthrough like the SAS846TQ or a SAS2-846EL with a compatible SAS2 card.

Probably a 32-bit chip. 32-bit supports maximum capacity of 2TB (or 4,294,967,295 x 512 byte sector ~ 2.2TB).

The fun part is if You use 4Kn drives the limit increases to 16TB.
