Dell PowerEdge RAID Controller 10 User’s Guide PERC H345, H740P, H745, and H840 Series Controllers

PERC 10 introduces the concept of profiles. A profile is user selectable. It defines controller queue depth and the maximum number of physical and virtual disks. There are two profiles: PD64 and PD240. The H740 supports only the PD64 profile. The H745P MX supports only the PD240 profile. The H840 supports both PD64 and PD240. PD240 is the default profile on H840. For more information see Changing profile using HII Configuration Utility.
