See the Maximum logical drive capacity supported on Intel® SAS RAID Controllers site for logical drive capacity information.
Remember for the best functionality to get drive from the Tested Hardware and Operating System List.
The HCL you point to is dated October 2009. Are there any plans to provide a more recent version? I'm keen to use a series of Hitachi Deskstar 7K3000 3TB drives with this controller, but they're not listed.
The SRCSAS18E is pretty old and likely there will be no more updates the the Tested Hardware and Operating Systems List for that controller.
One thing though, the SRCSAS18E uses the LSISAS1068 ROC chip. Due to a hardware limitation with the 1068 ROC chip, you will only be able to access up to 2TB space on > 2TB HDDs.
That was what I feared, thanks for the reply though.
