Description |
The boot media stores a primary and secondary set of boot image files that the system uses when it boots. |
|
You must replace the controller's caching module when your system registers a single AutoSupport (ASUP) message that the module has gone offline. |
|
The chassis is the physical enclosure housing all the controller components, such as the controller/CPU unit, power supply, and I/O. |
|
A controller consists of a board, firmware, and software. It controls the drives and implements the ONTAP functions. |
|
The data center persistent memory (DCPM) power module provides backup power for DCPM modules during unexpected power loss events. |
|
You must replace a DIMM (dual in-line memory module) when a memory mismatch is present, or you have a failed DIMM. |
|
A drive is a device that provides the physical storage media for data. |
|
A fan provides airflow for cooling system components and maintaining proper operating temperatures. |
|
An I/O module provides network and storage connectivity interfaces for the controller. |
|
The LED module provides visual status indicators for system health and component status. |
|
A mezzanine card provides additional I/O connectivity and expansion capabilities for the controller. |
|
You must replace an NVDIMM (non-volatile dual in-line memory module) when the module fails or shows errors. |
|
A battery is included with a controller and preserves cached data if the AC power fails. |
|
The NVRAM module provides non-volatile storage for system metadata and cached write data. |
|
PCI cards and risers provide expansion slots for additional functionality and I/O connectivity. |
|
A power supply provides a redundant power source in a controller shelf. |
|
A real-time clock battery preserves system date and time information if the power is off. |
|
The system management module provides out-of-band management capabilities for the system. |
