Drives
NVMe SSD LED definitions
The NVMe SSD is a PCIe bus device. A device attached to a PCIe bus cannot be removed without allowing
the device and bus to complete and cease the signal/traffic flow.
CAUTION: Do not remove an NVMe SSD from the drive bay while the Do not remove LED is flashing.
The Do not remove LED flashes to indicate that the device is still in use. Removing the NVMe SSD
before the device has completed and ceased signal/traffic flow can cause loss of data.

Drive guidelines
CAUTION: Do not remove an NVMe SSD from the drive bay while the Do Not Remove button LED is
flashing. The Do Not Remove button LED flashes to indicate the device is still in use. Removal of the
NVMe SSD before the device has completed and ceased signal/traffic flow can cause loss of data.
Depending on the configuration, this server supports SAS, SATA, and NVMe drives.
Observe the following general guidelines:

• Performing a logical drive extension
• Erasing

• For drive numbering, see Drive bay numbering on page 9.
• The NVMe SSD is a PCIe bus device. Do not remove a device attached to a PCIe bus without allowing it
to first complete and cease the signal/traffic flow.
• The system automatically sets all device numbers.
18 Component identification
• If only one hard drive is used, install it in the bay with the lowest device number.
• Install drives of the same capacity to provide the greatest storage space efficiency when drives are
grouped into the same drive array.

NVDIMM identification
NVDIMM boards are blue instead of green. This change to the color makes it easier to distinguish NVDIMMs
from DIMMs.
To determine NVDIMM characteristics, see the full product description as shown in the following example:
Item Description Definition
1 Capacity 16 GiB
2 Rank 1R (Single rank)
3 Data width per DRAM chip x4 (4 bit)
4 Memory type NN4=DDR4 NVDIMM-N
5 Maximum memory speed 2667 MT/s
6 Speed grade V (latency 19-19-19)
7 DIMM type RDIMM (registered)
8 Other —
For more information about NVDIMMs, see the product QuickSpecs on the Hewlett Packard Enterprise
website (http://www.hpe.com/info/qs).
NVDIMM 2D Data Matrix barcode
The 2D Data Matrix barcode is on the right side of the NVDIMM label and can be scanned by a cell phone or
other device.
When scanned, the following information from the label can be copied to your cell phone or device:
Component identification 29
• (P) is the module part number.
• (L) is the technical details shown on the label.
• (S) is the module serial number.
Example: (P)HMN82GR7AFR4N-VK (L)16GB 1Rx4 NN4-2666V-RZZZ-10(S)80AD-01-1742-11AED5C2
NVDIMM LED identification
Item LED description LED color
1 Power LED Green
2 Function LED Blue
NVDIMM-N LED combinations
State Definition NVDIMM-N Power LED
0 AC power is on (12V rail) but the NVM
controller is not working or not ready.
1 AC power is on (12V rail) and the NVM
controller is ready.
2 AC power is off or the battery is off (12V rail
off).
3 AC power is on (12V rail) or the battery is
on (12V rail) and the NVDIMM-N is active
(backup and restore).
NVDIMM Function LED patterns
For the purpose of this table, the NVDIMM-N LED operates as follows:
• Solid indicates that the LED remains in the on state.
• Flashing indicates that the LED is on for 2 seconds and off for 1 second.
• Fast-flashing indicates that the LED is on for 300 ms and off for 300 ms.
