Hello   Does the H730P controller support 4 x 4 drive RAID 10 arrays?     Yes The limits on the H730 exceed most hardware configurations. The H730 supports up to 64 virtual disks, so you could theoretically have 64x4 drive RAID 10s. There are span length and physical disk limitations to consider as well, but that configuration is not close to any limit of the controller. Thanks
Does the H730P controller support 4 x 4 drive RAID 10 arrays?  
How many arrays are supported with the PERC H730P controller?
