SAS Expander board
The SAS Expander board is necessary to achieve higher, single-volume hard drive configurations. An expander board allows the
C6400 to maximize the hard drive space in the hard drive bay. A single expander board supports up to 24 hard drives in the
C6400 chassis. The expander board is integrated with the 24 x 2.5-in backplane via MiniSAS hard drive connectors.
