• The Advanced ECC Support (maximum memory) setting disables additional resiliency and provides
the largest memory capacity to the OS.
• The Online Spare with Advanced ECC Support setting requires a single group of spare modules and
provides automatic failover of degraded modules in the system while it is running.
• The Mirrored Memory with Advanced ECC Support option provides protection against uncorrectable
memory errors that would otherwise result in system failure. DIMM banks A and B are mirrored by
DIMM banks C and D on the same memory board. The failed memory can be replaced while the
system is running.
Mirrored DIMM pairs must be the same size to allow selection of single-board mirrored memory or
dual-board mirrored memory. Pairing different size DIMMs results in the following caution:
Current memory configuration does not support Online Spare.
USB Control
The USB Control menu determines how USB ports and embedded devices operate at startup:
• When USB Enabled is selected, all USB ports and embedded devices are enabled.
• When USB Disabled is selected, all USB ports and embedded devices are disabled.
• When Legacy USB Disabled is selected, all USB ports are enabled under a USB-aware OS, but USB
is not supported during POST or RBSU. Legacy USB Disabled also disables iLO 2 virtual devices.
