Enables support for selected premium features, which include Snapshot, Super Sized Cache, FastPath, and Full Disk Encryption. IPMI-style I2C connector 3-pin connector. Supports SES (SCSI enclosure services) over I2C through an internal I2C backplane cable Remote Battery Backup 20-pin connector.Connects the intelligent Battery connector (on the back- Backup Unit remotely to the RAID controller. side of the controller) x4 SAS Ports 0-3 inter- SFF-8087 x4 internal mini SAS connector Con- nal connector nects the controller by cable to SAS/SATA drives. x4 SAS Ports 4-7 inter- SFF-8087 x4 internal mini SAS connector Con- nal connector nects the controller by cable to SAS/SATA drives. Standard edge card connector The RAID controller interfaces with the host system though a standard edge card. This interface provides power to the board and an I2C interface connected to the I2C bus for IPMI. x4 SAS Ports 8-11 inter- SFF-8087 x4 internal mini SAS connector Con- nal connector nects the controller by cable to SAS/SATA drives. Module CPLD 1x8-pin connector. Reserved for factory use. Activity LED header 2-pin connector. Connects to an LED that indicates activity on the drives connected to the controller. Global drive fault LED 2-pin connector. Connects to an LED that indicates header whether a drive is in a fault condition. LED Locate and Fault Indication header Ports 8-11 Ports 12-15 2x8-pin connector. Connects to an LED that indicates whether a drive is in a fault condition. There is one LED per port. When lit, each LED indicates the corresponding drive has failed or is in the unconfigured-bad state. The LEDs function in a direct-attach configuration (there are no SAS expanders). Direct attach is defined as a maximum of one drive connected directly to each port. x4 SAS Ports 12-15 internal connector SFF-8087 x4 internal mini SAS connector Connects the controller by cable to SAS/SATA drives. Write pending LED header 2-pin connector. Connects to an LED that indicates when the data in the cache has yet to be written to the storage devices. Used when the write-back feature is enabled.
