Split mode mapping configurations
CAUTION: Changing the storage sled mapping configuration from Joined mode to Split mode
can result in loss of configuration and/or loss of access to hard drives/SSDs.
NOTE: When changing the mapping configuration from Joined mode to Split mode, the secondary
PERC is powered on. It is recommended that you run the latest PERC firmware Dell Update Package
(DUP) to ensure that both PERCs are running the latest firmware.
The split mode mapping configurations apply to the following:
• The storage sled supports a storage controller module with dual PERCs.
• Both controllers are enabled by setting the Storage Mode to split mode in the CMC interface.
In the split mode, eight hard drives/SSDs are assigned map to each PERC. Hard drives/SSDs in slots 0 to 7
map to PERC 1 or primary controller, and hard drives/SSDs in slots 8 to 15 map to PERC 2. For more
information, see Drive to storage controller mapping.
There are two split mode options available in the CMC interface:
• Split Single Host mode
