Where multiple cards are installed and all devices require that their wattage be modified, add the serial numbers of each card and wattage as comma-separated items in the command. The wattage must be set in watts (75) and not in milliwatts (75000).įio-config -p FIO_EXTERNAL_POWER_OVERRIDE :.Use the fio-config command to persistently set the card into 75 watt threshold mode.75 watt support is provisioned within the physical slot, there are no BIOS/LifeCycle modifications required for enablement.Download the 'PowerEdge Slot Support Matrix' from the Dell-SanDisk support portal.Validate that the card is installed in a slot capable of supporting 75 watts.
To obtain the optimal performance from the device the card can be allocated additional power providing that the PCIe slot can support 75 watts. Under benchmarking (small-block writes) and specific customer applications, an ioDrive2 may under-perform by as much as 60% less than the published specification. This can occur as the card defaults to a PCIe power limit threshold of 25 watts and the card will run in power limited mode. Changing the cards PCIe power limit threshold from 25 watts to the maximum of 75 watts will allow the card performance to increase. A SanDisk or Fusion-IO ioDrive2 or ioDrive2 Duo device may under-perform against the published specifications if high power mode has not been enabled.
