Storage sled mapping configurations
The storage controller(s) inside a storage sled map to compute sled(s) in the enclosure. PowerEdge FX2s
supports multiple storage sled to compute sled mapping configurations.
NOTE: Storage sled to compute sled mapping is pre-configured.
NOTE: The PowerEdge FM120x4 compute sled does not support the storage sled. You cannot map
a storage sled to the PowerEdge FM120x4 half-width compute sled.
For information on configuring the storage mode in the storage sleds, see the PowerEdge FX2/FX2s CMC
User’s Guide at dell.com/esmmanuals.
Single PERC and joined mode mapping configurations
CAUTION: Changing the storage sled mapping configuration from Split Single Host mode to
Joined mode can change some hard drives/SSDs to non-RAID mode.
The single PERC and joined mode configurations apply to the following:
• The storage sled supports a storage controller module with a single PERC, and all hard drives/SSDs
map to the single PERC.
• The storage sled supports a storage controller module with dual PERCs, but only the primary
controller is enabled by setting the Storage Mode to Joined in the Chassis Management Controller
(CMC) interface. All hard drives/SSDs in the storage sled map to the primary PERC in the joined mode.
The following enclosure configurations support single PERC and joined mode mapping.
• Four-bay chassis—controllers inside two storage sleds map to two half-width compute sleds
• Four-bay chassis (one compute sled)—controllers inside three storage sleds map to one half-width
compute sled
• Six-bay chassis—controllers inside two storage sleds map to two quarter-width compute sleds
• Three-bay chassis—controllers inside two storage sleds map to one full-width compute sled
NOTE: PowerEdge FX2s supports multiple single PERC and joined mode mapping configurations.
You must select the desired configuration based on your intended usage.
