Enabling or disabling IO Identity Optimization
Normally, after the system boots, the devices are congured and then after a reboot the devices are initialized. You can enable the I/O
Identity Optimization feature to achieve boot optimization. If it is enabled, it sets the virtual address, initiator, and storage target attributes
after the device is reset and before it is initialized, thus eliminating a second BIOS restart. The device conguration and boot operation
occur in a single system start and is optimized for boot time performance.
Before enabling I/O identity optimization, make sure that:
• You have the Login, Congure, and System Control privileges.
• BIOS, iDRAC, and network cards are updated to the latest rmware. For information on the supported versions, see Supported cards
for IO Identity Optimization and Supported nic rmware version for i/o identity optimization.
After enabling I/O Identity Optimization feature, export the XML conguration le from iDRAC, modify the required I/O Identity attributes
in the XML conguration le, and import the le back to iDRAC.
