Hello wyeknott   This is because you are choosing a chassis configuration for "Embedded SATA". The very first set of options for "Chassis Configuration" allow you to choose between cabled, hotplug, and cabled with embedded SATA. If you choose any of the options that say embedded SATA at the end of them then your only RAID controller option will be the S110 software RAID controller as that is the embedded SATA controller. Thanks
I went to configure a T320 and found that the online order configurator only permitted "Software RAID." Anybody know why this is so?  I'm really not keen on "Software RAID" and I wonder if there's a hardware RAID option that the order-takers can furnish in lieu of the software RAID option.
T320 Hardware RAID Available?
