Dell Statement of Volatility – Dell EMC PowerEdge R750 Owner's Manual

Summary

Provides vital technical documentation detailing the data volatility of the Dell EMC PowerEdge R750 server components. This essential guide identifies which memory, flash, and controller modules are volatile (losing data upon power removal) versus non-volatile (retaining critical system information). Designed for IT professionals, system administrators, and support teams, it ensures accurate planning during system upgrades, maintenance, or unexpected power outages to guarantee complete operational data integrity.

Statement of Volatility – Dell EMC Power Edge R750 Dell EMC Power Edge R750 contains both volatile and non-volatile (NV) components. Volatile components lose their data immediately upon removal of power from the component. Non-volatile components continue to retain their data even after the power has been removed from the component. Components chosen as user- definable configuration options (those not soldered to the motherboard) are not included in the Statement of Volatility. Configuration option information (pertinent to options such as microprocessors, remote access controllers, and storage controllers) is available by component separately. The following NV components are present in the Power Edge R750 server.

Frequently Asked Questions

What is the difference between volatile and non-volatile components in this server?

Volatile components lose data immediately when power is removed, while Non-volatile components retain their data.

Are there any types of memory or flash areas that cannot be manually cleared by a user?

Yes. Memory areas like Dell SW, LOM SPI FLASH and Update Package(DUP) are protected from user clearing and updates.

What physical backplane options are available for storage expansion?

Available options include 2.5" Universal SAS/SATA/NVMe rear and front backplanes, as well as 3.5" SAS/SATA front backplates.
