I/O modules and slot assignments
See
DD2500 slot assignments on page 10
for the I/O module slot assignments of the
system.
Table 2 DD2500 slot assignments
Slot Number
DD2500 System
0
FC, Ethernet or empty
1
FC, Ethernet or empty
2
FC, Ethernet or empty
3
SAS or empty
4
NVRAM-BBU
When a DD2500 system is upgraded, the newly inserted I/O module should go into the
next available slot position. The following slot loading rules apply:
l
For mixed populations, populate all Ethernet I/O modules first, then populate the FC
I/O modules.
l
For Ethernet I/O modules, populate the leftmost (slot 0) slot first, if empty, then slot 1
and so on.
l
Slot 3 is reserved for SAS I/O modules only.
FC I/O module option
The FC I/O module is a dual-port Fibre Channel module. The optional virtual tape library
(VTL) feature requires at least one FC I/O module. Three FC I/O module slots are available
for use.
Ethernet I/O module options
The following Ethernet I/O modules are available:
l
Dual Port 10GBase-SR Optical with LC connectors
l
Dual Port 10GBase-CX1 Direct Attach Copper with SPF+ module
l
Quad Port 1000Base-T Copper with RJ-45 connectors
l
Quad port 2-port 1000Base-T Copper (RJ-45)/2-port 1000Base-SR Optical
You can use up to three I/O module slots for Ethernet connectivity.
