Appendix C Hot removal and managed hot removal of NVMe drives

The server supports hot removal and managed hot removal of NVMe drives.

Managed hot removal of NVMe drives enables you to remove NVMe drives safely while the server is operating.

Use Table 13 to determine the managed hot removal method depending on the VMD status and the operating system. By default, the VMD status is Auto. For more information about VMD, see the BIOS user guide for the server.

Table 13 Managed hot removal methods

VMD status	Operating system	Managed hot removal method
Auto/Enabled	Windows	Performing a managed hot removal in Windows.
Auto/Enabled	Linux	Performing a managed hot removal in Linux.
Disabled	N/A	Contact the support.

Performing a managed hot removal in Windows

Prerequisites

Install Intel^® Rapid Storage Technology enterprise (Intel^® RSTe).

To obtain Intel^® RSTe, use one of the following methods:

· Go to https://platformsw.intel.com/KitSearch.aspx to download the software.

· Contact Intel Support.

Procedure

1. Stop reading data from or writing data to the NVMe drive to be removed.

2. Identify the location of the NVMe drive. For more information, see "Drive LEDs."

3. Run Intel® RSTe.

4. Unmount the NVMe drive from the operating system, as shown in Figure 19:

¡ Select the NVMe drive to be removed from the Devices list.

¡ Click Activate LED to turn on the Fault/UID LED on the drive.

¡ Click Remove Disk.

Figure 19 Removing an NVMe drive

5. Observe the Fault/UID LED on the drive. If the Fault/UID LED turns steady blue and the drive is removed from the Devices list, remove the drive from the server.

Performing a managed hot removal in Linux

In Linux, you can perform a managed hot removal of NVMe drives from the CLI.

Performing a managed hot removal from the CLI

1. Stop reading data from or writing data to the NVMe drive to be removed.

2. Identify the location of the NVMe drive. For more information, see "Drive LEDs."

3. Access the CLI of the server.

4. Execute the lsblk | grep nvme command to identify the drive letter of the NVMe drive, as shown in Figure 20.

Figure 20 Identifying the drive letter of the NVMe drive to be removed

5. Execute the ledctl locate=/dev/drive_letter command to turn on the Fault/UID LED on the drive. The drive_letter argument represents the drive letter, nvme0n1 for example.

6. Execute the echo 1 > /sys/block/drive_letter/device/device/remove command to unmount the drive from the operating system. The drive_letter argument represents the drive letter, nvme0n1 for example.

7. Observe the Fault/UID LED on the drive. If the Fault/UID LED turns steady amber, remove the drive from the server.

Appendix D Environment requirements

About environment requirements

The operating temperature requirements for the server vary depending on the hardware configuration. When the general and component-based requirements conflict, use the component-based requirement.

Be aware that the actual maximum operating temperature of the server might be lower than what is stated because of poor site cooling performance. In a real data center, the server cooling performance might decrease because of adverse external factors, including poor cabinet cooling performance, high power density inside the cabinet, or insufficient spacing between devices.

General environment requirements

Item	Specifications
Operating temperature	Minimum: 5°C (41°F) Maximum: Varies depending on the power consumed by the processors and presence of expansion modules. For more information, see "Operating temperature requirements."
Storage temperature	–30°C to +60°C (–22°F to +140°F)
Operating humidity	· Without drives installed at the server rear: 10% to 90%, noncondensing · With drives installed at the server rear: 8% to 90%, noncondensing
Storage humidity	5% to 95%, noncondensing

Operating temperature requirements

Use Table 14 to determine the maximum operating temperature of the server with different configurations.

If a single fan fails, the maximum server operating temperature drops by 5°C (41°F) and the GPU performance might degrade.

NOTE:

All maximum server operating temperature values are provided on the basis that all the fans are installed and operating correctly. For more information about fan configurations, see the guidelines in "Replacing a fan."

Table 14 Operating temperature requirements

Maximum server operating temperature	Hardware option configuration
30°C (86°F)	A GPU installed in slot 3 or 6.
35°C (95°F)	· Front NVMe drives. · Rear drives. · GPUs installed in a slot other than slot 3 and slot 6.
40°C (104°F)	None of the above hardware option confirmations exists.
