Dell PowerEdge RAID Controller 10 User’s Guide PERC H345, H740P, H745, and H840 Series Controllers
RAID 10 configuration
In PERC 10 and PERC 11 controllers, RAID 10 can be configured without spanning up to 32 drives. Any RAID 10 volume that has more than 32 drives require spanning. Each span can contain up to 32 drives. Drives must be distributed evenly across all the spans with each span containing an even number of drives.
NOTE:Spans in a RAID 10 volume are only supported if spans are even. Uneven spanned RAID 10 cannot be imported from previous controller generations.
The following table shows the RAID 10 configurations.
