Tri-Mode Storage Adapter Technical Specifications
This chapter presents the technical specifications of each board, including operating conditions and power supply
requirements.
Operating and Non-operating Conditions
The following table lists the operating (thermal and atmospheric) conditions and non-operating (such as storage
and transit) environment for the storage adapters. The minimum airflow, measured as linear feet per minute (LFPM)
at 55°C, must be met to avoid operating the controller’s processor and board components above their maximum
junction temperatures.

Tri-Mode Storage Adapter Power Supply Requirements
All power is supplied to the tri-mode storage adapter through the PCIe 3.3V rails (3.3V ±9%) and the 12V rail (12V ±8%).
Onboard switching regulator circuitry operates from the 3.3V rails and the 12V rail provides the necessary voltages.
Typical power is measured with maximum I/O traffic, typical silicon process material, and nominal voltages operating the
card at an ambient temperature of 45°C with required airflow.
The system might transmit a PCI Set Slot Power Limit Message that indicates the maximum amount of power that the
adapter might use. During the start-up procedure, the adapter’s power consumption is limited to 25W because the storage
phys are not enabled until the Auto Port Enable procedure begins. When this procedure begins, the adapter’s power
check algorithm compares the power allocated by the SET_SLOT_POWER_LIMIT message to the adapter’s slot power
requirement. If the SET_SLOT_POWER_LIMIT message indicates that the slot’s power budget is at or greater than the
adapter’s requirement, Auto Port Enable proceeds. Refer to SAS95xx Adapters and SAS96xx Adapters Slot Power Limit
Settings Specification for more information on slot power requirements.
If no SET_SLOT_POWER_LIMIT message is received by the time Auto Port Enable is to start, the adapter continues with
port enable. You must make sure enough power is available to the slot if the SET_SLOT_POWER_LIMIT message is not
a. For adapters with a CVPM, this range applies with or without the CVPM attached.
