Slot Addition Rules
DD9500 and DD9800 systems have twelve slots for I/O modules. Slots 0, 2, 3, 6, 9,
and 11 are reserved for mandatory I/O modules. Slots 1, 4, 5, 7, 8, and 10 support
optional host interface I/O modules. The maximum supported number of any type of
host interface (Ethernet or FC) I/O module is four.
Note
The maximum number of host interface I/O modules listed above does not include the
10 GbE Optical I/O module for the HA interconnect. The HA interconnect is a fifth
Ethernet module, but it is reserved for communication between the two nodes of an
HA pair, and is not available for host connections.
The maximum number of I/O modules, including both mandatory and optional I/O
modules, supported in a DD9500 or DD9800 system varies by configuration:
l
Single node: 10
l
HA: 10
l
DD Extended Retention: 10
l
DD Cloud Tier: 10
l
HA + DD Cloud Tier: 11
Three I/O module slots are tied to each CPU in the DD9500 or DD9800 system. When
installing I/O modules, balance the load across the CPUs. The following table shows
the CPU to slot mappings.
