Enabling or disabling I/O Identity Optimization

Normally, after the system boots, the devices are configured 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 configuration 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, Configure, and System Control privileges.
• BIOS, iDRAC, and network cards are updated to the latest firmware. For information on the supported versions, see
cards for I/O Identity Optimization
After enabling I/O Identity Optimization feature, export the XML configuration file from iDRAC, modify the required I/O Identity
attributes in the XML configuration file, and import the file back to iDRAC.
For the list of I/O Identity Optimization attributes that you can modify in the XML configuration file, see the NIC Profile document
available at delltechcenter.com/idrac.
NOTE: Do not modify non I/O Identity Optimization attributes.

1. In the iDRAC Web interface, go to Overview → Hardware → Network Devices.
