Storage events from PERC are mapped to SNMP traps and WSMan events as applicable. Any changes to the storage
configurations are logged in the Lifecycle Log.
Table 49. PERC capability
PERC Capability CEM configuration Capable
Controller (PERC 9.1 or later)
CEM configuration Non-capable
Controller (PERC 9.0 and lower)
Real-time
NOTE: For the 14th generation of
PowerEdge servers, PERC 9 and
PERC 10 controllers are supported.
If there is no existing pending or
scheduled jobs for the controller, then
configuration is applied.
If there are pending or scheduled jobs
for that controller, then the jobs have
to be cleared or you must wait for the
jobs to be completed before applying
the configuration at run-time. Run-time
or real-time means, a reboot is not
required.
Configuration is applied. An error
message is displayed. Job creation is not
successful and you cannot create real-
time jobs using Web interface.
Staged If all the set operations are staged, the
configuration is staged and applied after
reboot or it is applied at real-time.
Configuration is applied after reboot

Understanding RAID concepts
Storage Management uses the Redundant Array of Independent Disks (RAID) technology to provide Storage Management
capability. Understanding Storage Management requires an understanding of RAID concepts, as well as some familiarity with
how the RAID controllers and operating system view disk space on your system.
What is RAID
RAID is a technology for managing the storage of data on the physical disks that reside or are attached to the system. A key
aspect of RAID is the ability to span physical disks so that the combined storage capacity of multiple physical disks can be
treated as a single, extended disk space. Another key aspect of RAID is the ability to maintain redundant data which can be
used to restore data in the event of a disk failure. RAID uses different techniques, such as striping, mirroring, and parity, to
store and reconstruct data. There are different RAID levels that use different methods for storing and reconstructing data. The
RAID levels have different characteristics in terms of read/write performance, data protection, and storage capacity. Not all
