Figure 14 Location of NVRAM and I/O modules (continued)
2. I/O modules—slots 1 to 11 (See the I/O module slot assignments table.)
Note
Slots 2, 3, and 6 (three I/O slots) are used for SAS I/O modules for systems without
Extended Retention (ER).
Note
Slots 2, 3, 6, and 9 (four I/O slots) are for SAS I/O modules for systems with ER or
DD Cloud Tier software.
The table shows the I/O module slot assignments for the DD9500 and DD9800
systems. Each type of I/O module is restricted to certain slots.
The I/O module slot assignments for the DD9500 and DD9800 systems are the same.
