I run an HP z800 workstation. Dual cpu and about 96gb ram. My bottle neck with this older server is the SAS 1.0 ports. Im picking up a raid controller LSI 9267 8i. This will give me SAS 2.0 in the same system. Then I can see drives larger than 2gb. I'm out of space so I need to upgrade bad. What kind of complications will I run into if i connect this controller and all the current drives? I cant lose the data on these drives.
Would it be better to install the controller, install a few larger drives, then plug in my old drives?
