3.2 MegaRAID 320-0X Storage Adapter Characteristics
Table 3.2 shows the general characteristics for all MegaRAID 320-0X
storage adapters.
The MegaRAID 320-0X storage adapter ensures data integrity by
intelligently validating the integrity of the SCSI domain. The storage
adapters also use Fusion-MPT architecture that allows for thinner drivers
and better performance.
J6 Write-pending Indicator
(dirty cache) LED 2-pin header
Connector for an LED mounted on the system enclosure. The
LED indicates when the data in the cache has yet to be written
to the storage devices.
J7 Onboard BIOS
Disabled 2-pin header
Disables the BIOS so that it won’t run on the firmware.
J8 Serial EEPROM 2-pin connector
Provides board information, such as serial number, OEM
number, revision number, manufacturing data. This eliminates
the need to open the system to obtain board information.
J9 NMI (non-maskable
interrupt) 2-pin connector
Reserved for LSI Logic internal use.
