Dell PowerEdge R630 Statement of Volatility
This document outlines the volatile and non-volatile components within the Dell PowerEdge R630 server. Volatile components lose their data immediately upon power removal, while non-volatile components retain data even after power is removed. User-definable configuration options not soldered to the motherboard are excluded. Information on configuration options for components like microprocessors, remote access controllers, and storage controllers is available separately. The following non-volatile (NV) components are present in the PowerEdge R630 server.
