HighPoint’s SSD7580B is the industry’s only true Hot-Plug and Hot-Swap capable NVMe RAID controller. It allows administrators to add or remove an entire RAID array, or individual SSDs for specific RAID related tasks, using either the HighPoint WebGUI or CLI storage management and monitoring software.
Removing an SSD or RAID Array (aka Hot-Eject): Provided the array is not in use, administrators can use the CLI unplug command line, or the WebGUI “Unplug” button.
The management utilities will then safely “park” each SSD (power off and unmount), then notify the host operating system of the change. Once the operating system storage/drive utility recognizes that the array or disk has been unmounted, the SSD(s) can be safely removed from the system.
Adding an SSD: After the SSD is attached, Administrators can command the controller to scan its device ports for any changes, using the CLI rescan command, or the WebGUI’s Rescan button. Once the SSD is detected (this normally only takes a few seconds), it will immediately report this to the operating system.
Example Screenshot (CLI):
RAID arrays can also be unplugged or added to the controller while the system is live, but this requires an extra step, albeit a simple one.
Administrators will have to use the SSD7580B CLI (Command Line Interface) and enter “Unplug” and the “Rescan” commands located on the left-side of the interface when adding or removing an array. Once the CLI carries out the command, it should only take a few seconds for the operating system to catch up.
