ES40 overview

Storage capacity can be increased by adding ES40 expansion shelves to DD6900, DD9400, and DD9900 systems.

The expansion shelves are organized by sets (or chains). The following table shows the number of ES40 shelves that can be in a set.

Table 1. ES40 shelves in a set
System ES40 shelves
DD6900 1–7
DD9400 1–7
DD9900 1–7

For redundancy, a shelf set is connected to two separate SAS I/O modules or HBA cards on the controller, and all shelves within a set are connected to each other using dual paths.
