Connecting Disk Drives to HostRAID Controllers
You can connect SAS disk drives, SATA disk drives, or a combination of both to your
HostRAID controller. There are no jumpers or switches to set before installation.
If you plan to build a bootable array using internal disk drives, ensure you install at least the
minimum number disk drives required to support the RAID level you want. See
more information.
Note:
Although you can connect both SAS and SATA disk drives to your SAS controller,
Adaptec recommends that you not combine SAS and SATA disk drives within the same
array or logical drive. See
You have two connection options:
To connect directly to the controller, see

connector. (For more information about direct-attach connections, see
