Opal Security Management
Opal Security Management of Opal SED drives requires security key management support. You can use the application software
or The Integrated Dell Remote Access Controller (iDRAC) to generate the security key that is set in the Opal drives and used as
an authentication key to lock and unlock the Opal drives.
Hardware Root of Trust
Hardware RoT (RoT) builds a chain of trust by authenticating all the firmware components prior to its execution, and it permits
only the authenticated firmware to perform and be flashed. The controller boots from an internal boot ROM (IBR) that
establishes the initial root of trust and this process authenticates and builds a chain of trust with succeeding software using this
root of trust.
1 MB I/O
PERC 11 controllers support a 1 MB I/O feature; if the capacity of I/O frame is greater than 1 MB, the I/O frame is broken into
smaller chunks.
Auto Configure RAID 0
Auto Configure RAID 0 feature creates a single drive RAID 0 on each physical disk that is in the ready state. For more
information, see Auto Configure RAID 0 on page 44.
Auto Configure behavior
Auto configure behavior automatically configures unconfigured drives during reboot and hot insertion. As per the setting,
unconfigured drives will be configured as per the option; but the configured drives will remain unaffected. PERC 11 supports Off
and Non–RAID settings.
Table 2. Auto configure behavior settings
Settings Description
Off Auto configure behavior is turned off
Non–RAID Unconfigured drives are configured as non–RAID disk during boot or during hot insertion; all the
configured drives will remain unaffected
Off to Non–RAID disk Unconfigured drives are converted to non–RAID disk; all the configured drives will remain unaffected
Non–RAID disk to Off Unconfigured drives remain unconfigured good; all the configured drives will remain unaffected
Disk roaming
Disk roaming is when a physical disk is moved from one cable connection or backplane slot to another on the same controller.
The controller automatically recognizes the relocated physical disks and logically places them in the virtual disks that are part of
the disk group. If the physical disk is configured as a non–RAID disk, then the relocated physical disk is recognized as a non–
RAID disk by the controller.
CAUTION: It is recommended that you perform disk roaming when the system is turned off.
CAUTION: Do not attempt disk roaming during RAID level migration (RLM) or online capacity expansion (OCE).
This causes loss of the virtual disk.
