iSCSI with JBOD Expansion
JBOD expansion requires at least one SFF-8088 4X to SFF-8088 4X external
SAS cable for each JBOD unit.
To add JBOD units:
1. Connect the SAS expansion port on the left controller of the RAID
subsystem to the SAS data IN port on the left I/O module of the first JBOD
unit.
See Figure 14.
2. Connect the SAS expansion port on the right controller of the RAID
subsystem to the SAS data IN port on the right I/O module of the first JBOD
unit.
3. Connect the SAS data OUT port on left I/O module of the first JBOD unit to
the SAS data IN port on the left I/O module of the second JBOD unit.
4. Connect the SAS data OUT port on right I/O module of the first JBOD unit to
the SAS data IN port on the right I/O module of the second JBOD unit.
5. Connect the remaining JBOD units in the same manner.
• Keep your data paths organized to ensure redundancy.
• JBOD expansion supports up to nine (9) JBOD units.
