The server provides six 2.5-inch drive bays, accessible through the front panel. Drives can be removed and installed while the server is running. This feature, referred to as being hot-swappable, depends on how the drives are configured.
Note - Both traditional, disk-based storage devices, and Flash SSDs, which are diskless storage devices based on solid-state memory, are supported. The terms “drive” and “HDD” are used in a generic sense to refer to both types of internal storage devices.
To hot-swap a drive, you must first take it offline. This prevents applications from accessing the drive and removes software links to it.
A drive should not be hot-swapped when either of the following conditions exist:
The drive contains the sole image of the operating system–that is, the operating system is not mirrored on another drive.
The drive cannot be logically isolated from the server's online operations.
If either condition exists, you must power off the server before replacing the drive.
