Intel SRCSAS18E User Manual

6

The following list describes the usability features.

• Simplifies cabling with point-to-point, serial architecture
• Smaller, thinner cables do not restrict airflow
• Provides drive spin-up sequencing control
• Provides an Inter-IC (I

2

C) interface for enclosure management

These features increase the flexibility of the SAS RAID controller.

• Supports a Flash ROM interface, a nonvolatile RAM (NVSRAM) interface
• Offers a flexible programming interface to tune I/O performance
• Allows mixed connections to SAS or SATA targets
• Leverages compatible connectors for SAS and SATA connections

Drive roaming occurs when the hard drives are changed to different ports on the same 

controller. When the drives are placed on different ports, the controller detects the RAID 

configuration from the configuration data on the drives. 

Perform the following steps to use drive roaming:

1. Turn off all power to the server and all hard drives, enclosures, and system 

components, then disconnect power cords from the system.

2. Open the host system, following the instructions in the host system technical 

documentation.

3. Move the drives to different positions on the backplane to change the targets.
4. Determine the SAS target requirements.
5. Perform a safety check. 

— Make sure the drives are inserted properly.
— Close the cabinet of the host system.
— Turn power on after completing the safety check.

6. Power on the system.

The controller detects the RAID configuration from the configuration data on the drives.
