Management applications for PERC cards
Dell OpenManage Storage Management applications enable you to manage and configure the RAID system, create and manage
multiple disk groups, control and monitor multiple RAID systems, and provide online maintenance. The management applications
for all PERC cards include:
Comprehensive Embedded Management
Dell OpenManage Storage Management
Human Interface Infrastructure (HII) Configuration Utility
The PERC CLI
NOTE: The BIOS configuration utility <Ctrl> <R> is not supported on PERC 10 cards.
Comprehensive Embedded Management
Comprehensive Embedded Management (CEM) is a storage management solution for Dell systems that enables you to
effectively monitor the RAID and network controllers installed on the system using iDRAC without an operating system installed
on the system.
Using CEM enables you to perform the following:
Monitor devices with and without an operating system installed on the system.
Provide a specific location to access monitored data of the storage devices and network cards.
Allows controller configuration for all PERC 10 cards.
NOTE:
If you boot the system to HII (F2) or Lifecycle Controller (F10), then you cannot view the PERC cards on the CEM
UI. The PERC cards are displayed on the CEM UI only after the system boot is complete.
NOTE: It is not recommended to create more than 8 VDs simultaneously with CEM.
