Whether to Use the LED Status Connector
3ware RAID controllers include two types of LED status
connectors:
Overall indicator, which lights when any drive is active.
Individual LED indicators, for each drive. (Not supported on
chassis that have a common ground.)
If you are building a system from scratch, you may want to consider
using a chassis or drive carrier that is compatible with the 3ware
RAID controller activity LEDs, such as the AMCC RDC-400 drive
carrier, available through AMCC. Please check the 3ware web site
(www.3ware.com) for chassis and drive carrier compatibility list.
For more information, see “Additional Details About the LED
Status Connectors” on page 13.
Most chassis have a single drive activity cable that you can connect
to the overall activity indicator on the 3ware 9000 controller. For
the location of the overall drive activity connector, see the figure for
the appropriate controller in the installation sections starting on
page 12, and refer to Table 1, “LED Indicator Pin Positions,” on
page 14.
Drive Installation Considerations
Selecting an enclosure. If you are planning to use RAID 1, 5,
10, or 50, you may want to consider installing drives into hot-
swappable enclosures, so that they can be easily removed in the
event of a drive failure.
When to install the drive. If the drives are not already installed
in your computer, you can choose to install them either before
or after connecting the interface cables to them.
