Dell PowerEdge Express Flash NVMe PCIe SSD SFF P4500/P4600 User’s Guide

The NVMe PCIe SSD supports orderly hot swap allowing you to add or remove a device without halting or restarting the system in which the device is installed.

The supported NVMe PCIe SSD hot swappable functions are defined below:

Orderly or Hot Insertion

You insert a device into a running system where a similar device has not been previously inserted from the time it was last booted. The systems that support NVMe PCIe SSDs are configured to handle the PCIe resource balancing in the event of a hot insertion, when operating within a Dell supported operating system. This preset system configuration makes the hot insertion an orderly operation, if performed with supported operating systems.

Orderly Removal

You remove a device from a running system. Prior to physically removing the device, you must notify the system that the device is about to be removed. This notification defines hot removal as an orderly operation.

Orderly Swap

You remove a device from the system in an orderly fashion and replace it with a supported device. The device that is removed and the device that replaced it use the same device driver.
