Table of Contents

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/

Single PERC/HBA Controller 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/HBA Controller and joined mode configurations apply to the following:

•

The storage sled supports a storage controller module with a single controller, and all hard drives/SSDs map to the single controller.

•

The storage sled supports a storage controller module with dual controllers, 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 controller in the joined mode.

The following enclosure configurations support single PERC/HBA controller 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/HBA controller and joined mode mapping configurations. You must

select the desired configuration based on your intended usage.
