14 Intel® RAID Controller SASMF8I Hardware User’s Guide
Electrical Characteristics
This section provides the power requirements for the Intel
®
RAID Controller SASMF8I.
Table 5 lists the maximum power requirements.
Thermal and Atmospheric Characteristics
The thermal and atmospheric characteristics are:
• Relative humidity range: 5% to 90% non-condensing
• Maximum dew point temperature: 32°C
• Airflow must be at least 200 linear feet per minute (SFPM) to avoid operating above
the maximum ambient temperature.
The storage and transit environment conditions are:
• Temperature range from -30°C to 80°C (dry bulb).
• Relative humidity range: 5% to 90% non-condensing
Safety Characteristics
The Intel
®
RAID Controller SASMF8I meets or exceeds the requirements of UL
flammability rating 94 V0. Each bare board is also marked with the supplier name or
trademark, type, and UL flammability rating. For the boards installed in a PCI Express*
bus slot, all voltages are lower than the SELV 42.4 V limit.
Drive Rebuild Using
Hot Spares
• Automatic at drive failure
• Auto-resume of initialization or rebuild on reboot
Error Checking and
Indication
• Parity generation and checking, automatic consistency checking
• Activity and fault LEDs
Power Conservation Staggered spin-up, lower power requirements.
