Each I/O module on a Drive Enclosure has three SAS ports. The SAS ports provide the interconnection between the Drive Enclosures and the Controllers. The SAS ports also provide the interconnections between Drive Enclosures.
The following figure shows the SAS ports of a DE2-24P Drive Enclosure. Note the position of the SAS ports and the reverse orientation of the two I/O modules. Remember the orientation of the I/O modules and the location of the SAS ports as you cable the system.
1 I/O module 0 | 5 I/O module 1 |
2 I/O module 0, SAS port 0 | 6 I/O module 1, SAS port 0 |
3 I/O module 0, SAS port 1 | 7 I/O module 1, SAS port 1 |
4 I/O module 0, SAS port 2 | 8 I/O module 1, SAS port 2 |
The following figure shows the SAS ports of a DE2-24C Drive Enclosure. Note the position of the SAS ports and the identical orientation of the two I/O modules. Remember the orientation of the I/O modules and the location of the SAS ports as you cable the system.
1 I/O module 0 | 5 I/O module 1 |
2 I/O module 0, SAS port 0 | 6 I/O module 1, SAS port 0 |
3 I/O module 0, SAS port 1 | 7 I/O module 1, SAS port 1 |
4 I/O module 0, SAS port 2 | 8 I/O module 1, SAS port 2 |
