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 Supported BIOS Version For I/O Identity Optimization and Supported NIC Firmware
Version 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.
