SAS Expander Daughter Card
The systems storage uses SAS expander daughter card to facilitate:
•transition of SAS technology from 6 Gb/s to 12 Gb/s
•maximize the hard disk drive space
•provide the configuration flexibility and cabling and signalling issues of the system
The daughter card uses LSI expander chips that supports:
•Up to 12 gb/s SAS
•Up to 6 Gb/s SAS and SATA
•Serial SCSI Protocol (SSP)
•
•Simple Management Protocol (SMP) and their communication with the RAID controllers.
NOTE: The expander daughter card sled supports up to two daughter cards(depending on the configuration).
