Intel Optane DC Persistent Memory - Configuration and Setup White Paper

7TECHNICAL WHITE PAPER
2. Set up the hardware:
a) Check system setup as outlined in the above System Requirements Section.
b) Congure the hardware. See the “How to Congure System HW” subsection below.
c) HP Recommends BIOS and DCPMM FW be updated to latest version before SW conguration begins.
3. Put the modules into the desired mode (see appendices A through D as appropriate)
• To set up the DCPMM into Memory Mode:
a) Congure NVDIMMs to Memory Mode following the procedure in the appropriate appendix (A through D).
b) Verify setup in BIOS and in the OS to make sure that the memory is reported as expected.
• To set up the DCPMM into Storage Mode:
a) Create a Region (in F10 setup, automatically also creates namespace).
b) Create Namespace with BTT (only necessary if the region was created in UEFI or OS).
c) Enable BTT.
d) Enable Security if desired.
e) Go into the OS to partition and format the drive.
°
HP recommends that DAX be enabled in the le system
f) Review result and verify setup.
• To set up the DCPMM into App Direct Mode:
a) Create a Region (in F10 Setup, automatically creates namespace).
b) Create Namespace without BTT (only necessary if the region was created in UEFI or OS).
c) Enable Security if desired.
d) Go into the OS to partition and format the drive.
e) Review result and verify setup.
How to Congure System HW: DCPMM &
Memory Load order/rules
• Load Rules:
°
At least one DRAM DIMM is required on the same side (memory controller) of a processor as a DCPMM.
°
Load the DRAM rst and then load the DCPMM.
°
Load the memory modules in order of size, starting with the largest DRAM module.
°
After the DRAM memory is installed, continue to follow the loading order with the DCPMM.
°
See Service panel label on Chassis cover or the Z6 G4 or Z8 G4 Workstation Technical White paper
for the complete memory loading rules.
°
See Appendix G for details on recommended module loading.
• Memory Mode:
°
To maximize bandwidth, install DRAM across as many channels as possible.
• Storage Mode
°
HP recommends loading the DCPMM in sets of two modules per CPU (to allow interleaving).
°
For a conguration of two DCPMMs on a dual processor system, HP recommends installing both DCPMMs
on the rst processor.
Maintaining and upgrading modules
Here we outline some other common tasks associated with managing a system with DCPMMs. Detailed procedures
are covered in Appendices A through D and in Appendix F.
• Update Firmware
°
There are occasions that will require the rmware on the DCPMM to be updated. When these occasions
occur, HP will provide the rmware binary as a SoftPaq on the HP support website. The preferred method
to update rmware is through F10 Setup. Firmware can also be updated from the OS or UEFI shell.
• Memory Mode:
°
Recongure (add, subtract, replace DCPMMs).
– Install the DCPMM in the correct location based on the recommended loading rules
– Verify setup in BIOS and in the OS
• Storage Mode:
°
Back up data
– Data on DCPMM is to follow present day customer/company specic standards for ensuring there is
a backup of important les crucial for day to day business. DCPMM backup should follow practices used
on SATA, SAS, and NVMe

Reset/recongure
– There might be instances when you want to reset one or more DCPMM modules. This could be
