Hello all,

I'm trying to figure out the best configuration for performance to create a single RAID 10 virtual disk across 24 physical disks.

It seems that I can span as few as 4 and as many as 12 physical disks per span. With 4 per span I would have 6 spans total, with 12 I would have 2 spans. But no where in the documentation have I seen notes related to performance or any related trade-offs.

Does anyone have any thoughts or point me to a resource that discusses best practices for determining the number of physical disks per span?

Thanks! Dell Description of Spans Across RAID 10
