The internal components of a storage system enable the system to function.
| Component |
Description |
|---|
| system board |
The system board is also referred to as the main board of the storage system. It has upgradable firmware. All components are connected to the system board. |
| system memory |
System memory stores information temporarily. |
| NVRAM (Nonvolatile RAM) |
Data ONTAP uses NVRAM to log network transactions as a data integrity measure. In case of a system or power failure, Data ONTAP uses the contents of NVRAM to restore network data to disk. |
| CompactFlash card (not available on all models) |
The storage system automatically boots from a Data ONTAP release stored on the CompactFlash card. The CompactFlash card also stores a backup version of Data ONTAP from which to boot the storage system in an emergency. |
| LCD and LEDs |
The storage system displays status information on the LCD and LEDs. |
| environmental adapter |
The environmental adapter performs the following functions:- Monitors the storage system’s temperature and fans
- Sends critical information to the storage system’s LCD
- Logs information
- Shuts down the storage system if its temperature is beyond a critical range or the fans cease operating
|
| Remote Management Controller (RMC) (not available with all storage systems) |
The RMC provides enhanced AutoSupport, such as “down filer” notification. |
| RLM (Remote LAN Module) and BMC (Baseboard Management Controller) (not available with all storage systems) |
The RLM and the BMC provides remote platform management capabilities for the storage system, allowing you to remotely access the storage system console over a network, and turning the storage system power on or off regardless of the operating state of the storage system. The RLM and the BMC monitors and maintains hardware event logs for the storage system and generate alerts based on system status.
