Chapter 5: Installing the HostRAID Controller and Disk Drives ●25

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 page 58 for

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 page 55 for more information.

You have two connection options:

●To connect directly to the controller, see page 25.

●To connect to a backplane, see page 26.

Connecting Directly to the HostRAID Controller

In a direct-attach connection, SAS or SATA disk drives are connected directly to a SAS card

with SAS cables.The number of direct-attached disk drives is limited to four per internal SAS

connector. (For more information about direct-attach connections, see page 56.)

1Install your internal SAS or SATA disk drives, following the instructions in your system’s

documentation.

2Use internal SAS cables to attach the disk drives to the controller.

3When all internal disk drives have been installed and attached to the controller, close your

computer cabinet, re attach the power cord, then co ntinue with Installing the Controller to a

SAS Expander on page 27.
