HA systems are the exception to this guidance, as a Quad Port 10GbE SR I or Quad Port 10
GBase-T /O module can be added in slot 10 alongside the HA interconnect I/O module in
slot 11.
The storage processor (SP) is a subassembly within the chassis that contains the
memory risers with the DIMMs and a fan tray with fan modules. The SP module also
contains the 4 CPUs, which cannot be removed or replaced.
The memory risers tray, which contains 8 memory risers with DIMMs, can be
l
accessed from the front of the SP module. The memory risers are not hot
swappable
The fan tray, which contains 8 fan modules, can be accessed from the front of the
l
SP module. The fans are hot swappable.
The DIMMS can be accessed by pulling the entire SP module away from the chassis.
Depending on the model, there are DIMMs totaling:
256 GB or 512 GB for a DD9500 system.
l
256 GB or 768 GB for a DD9800 system.

The figures show the location of the SP module, the DIMM risers accessed from a
partly removed SP module, and the fan tray partly removed.
Do not lift the DD9500/DD9800 system, or the storage processor (SP) module, or
any modules by the handle. The handle is not designed to support the weight of the
populated shelf. Also do not carry the DD9500/DD9800 system or the SP by the
handle. The handles are only intended to be used to insert or remove the SP module.

Notes
This slot remains
empty if the system
does not use DD
Cloud Tier or DD
Extended Retention.
This slot remains
empty if the system
does not use HA.
Install host interface
I/O modules in the
remaining slots. Install
the I/O modules to
balance the load
across the CPUs. Do
not place two
Ethernet or two FC
I/O modules on one
a
CPU.
