1-10 NVDIMM Memory Support (For X9DRH-iF & -iF-NV)
Non-Volatile DIMM (NVDIMM) is a new technology that offers efcient data protec-
tion during a sudden power outage without using traditional data backup. Utilizing
the CPU's own memory bus, NVDIMM eliminates latency and power issues associ-
ated with conventional backup methods via SATA or PCI-E SDD devices, greatly
reducing the total cost of ownership (TCO). This environmentally friendly technol-
ogy is ideal for data-intensive platforms such as RAID storage/cache backup, San
management, disaster recovery, and online transaction processing (OLTP).
The X9DRH-iF/-iF-NV supports NVDIMM modules at the BIOS and hardware level.
For proper operation, NVDIMM modules generally require additional OS and soft-
ware support. Supermicro motherboards support the following two "trigger methods"
which enable the NVDIMM to begin a save cycle:
•ADR (Automatic DRAM Self-Refresh)_trigger method is recommended by Intel.
In the event of a power loss, ADR will disable all higher-level CPU functions
except those related to the memory controller, allowing only a limited portion
of the CPU cache to "remain alive" for NVDIMM preservation. This method is
available for the X9DRH-iF-NV model only.
•NMI (Non-Maskable Interrupt)_ trigger method is a proprietary, innovative ap-
proach jointly developed by Supermicro and Viking Technologies to allow the
system to maintain optimal CPU performance without disabling any of the cache
in the event of a power loss, allowing the NVDIMM to capture additional cache
data. This method is available for the X9DRH-iF model only
Please consult the installation guide provided by your NVDIMM vendor for proper
installation of NVDIMM modules and the corresponding Supercap. Be sure to con-
tact your Supermicro sales representatives for the most current list of supported
NVDIMM modules.
