Enabling or disabling I/O 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 I/O 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.
For the list of I/O Identity Optimization attributes that you can modify in the XML conguration le, see the NIC Prole document
available at delltechcenter.com/idrac.
NOTE: Do not modify non I/O Identity Optimization attributes.
Enabling or disabling I/O Identity Optimization using web interface
To enable or disable I/O Identity Optimization:
1. In the iDRAC Web interface, go to Overview → Hardware → Network Devices.
The Network Devices page is displayed.
2. Click the I/O Identity Optimization tab, select the I/O Identity Optimization option to enable this feature. To disable, clear this
option.
3. Click Apply to apply the setting.
Enabling or disabling I/O Identity Optimization using RACADM
To enable I/O Identity Optimization, use the command:
racadm set idrac.ioidopt.IOIDOptEnable Enabled
After enabling this feature, you must restart the system for the settings to take eect.
