HPE 16GB NVDIMM option
HPE NVDIMMs are flash-backed NVDIMMs used as fast storage and are designed to eliminate smaller storage bottlenecks.
The HPE 16GB NVDIMM for HPE ProLiant Gen10 servers is ideal for smaller database storage bottlenecks, write caching tiers,
and any workload constrained by storage bottlenecks.
The HPE 16GB NVDIMM is supported on select HPE ProLiant Gen10 servers with first generation Intel Xeon Scalable
processors. The server can support up to 12 NVDIMMs in 2 socket servers (up to 192GB) and up to 24 NVDIMMs in 4 socket
servers (up to 384GB). The HPE Smart Storage Battery provides backup power to the memory slots allowing data to be moved
from the DRAM portion of the NVDIMM to the Flash portion for persistence during a power down event.
For more information on HPE NVDIMMs, see the Hewlett Packard Enterprise website ( http://www.hpe.com/info/
persistentmemory).
NVDIMM-processor compatibility
HPE 16GB NVDIMMs are only supported in servers with first-generation Intel Xeon Scalable processors installed.
Server requirements for NVDIMM support
Before installing an HPE 16GB NVDIMM in a server, make sure that the following components and software are available:
• A supported HPE server using Intel Xeon Scalable Processors: For more information, see the NVDIMM QuickSpecs on the
Hewlett Packard Enterprise website (
http://www.hpe.com/info/qs).
• An HPE Smart Storage Battery
• A minimum of one regular DIMM: The system cannot have only NVDIMM-Ns installed.
• A supported operating system with persistent memory/NVDIMM drivers. For the latest software information, see the
Hewlett Packard Enterprise website ( http://persistentmemory.hpe.com).
• For minimum firmware versions, see the HPE 16GB NVDIMM User Guide on the Hewlett Packard Enterprise website
(
http://www.hpe.com/info/nvdimm-docs).
To determine NVDIMM support for your server, see the server QuickSpecs on the Hewlett Packard Enterprise website (
http://
www.hpe.com/info/qs).
Installing an NVDIMM
CAUTION: To avoid damage to the hard drives, memory, and other system components, the air baffle, drive blanks, and
access panel must be installed when the server is powered up.
CAUTION: To avoid damage to the hard drives, memory, and other system components, be sure to install the correct
DIMM baffles for your server model.
CAUTION: DIMMs are keyed for proper alignment. Align notches in the DIMM with the corresponding notches in the
DIMM slot before inserting the DIMM. Do not force the DIMM into the slot. When installed properly, not all DIMMs will
face in the same direction.
CAUTION: Electrostatic discharge can damage electronic components. Be sure you are properly grounded before
beginning this procedure.
