DDR4 Non-Volatile DIMM, which gives enterprise applications both performance and durability. Through the use of DDR4 DIMM sockets, this persistent memory module can be installed in servers that support NVDIMM. created to protect important data in the case of a power outage or system failure.
When operating normally, many “non-volatile” products use volatile memory; but, when the power fails, they use an on-board backup power source to dump the contents into non-volatile memory. Volatile memory is byte-addressable, faster than non-volatile memory, and it may be written to arbitrarily without worrying about wear and device longevity.
The Global DDR4 NVDIMM market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
In order to accommodate persistent memory consumption models, Micron launched their next generation of NVDIMM-N modules integrating DDR4 DRAM with NAND flash memory.
The new 32GB modules have twice the storage space of Micron’s prior NVDIMMs and have a speed rating of DDR4-2933 CL21, which is faster than what is supported by the most recent server platforms.
The Non-Volatile DIMM business is not a new one for Micron; their initial DDR3 NVDIMMs were produced before JEDEC standardisation. Prior to the new 32GB modules, 8GB and 16GB DDR4 NVDIMMs were available.
The NVDIMMs from Micron are type N, which means they perform the same functions as regular ECC DRAM DIMMs but feature NAND flash as a backup for data in the event of a power outage.
The NVDIMM-F kind, on the other hand, provides pure flash storage.The module’s onboard FPGA-based manages saving the contents of the DRAM to the module’s 64GB of SLC NAND flash when the system encounters a power breakdown or warns that one is about to occur.
In the event of a power outage, the module can be powered either by a battery backup provided through the 12V pins on the DIMM slot or by connecting a cable to an external AGIGA PowerGEM capacitor module.
According to Micron, high-performance journaling and log storage for databases and filesystems are the most frequent use cases for NVDIMMs. The new Micron 32GB modules enable these systems to use just one NVDIMM per CPU, whereas in these applications a 2S server will normally be outfitted with a total of roughly 64GB of NVDIMMs.
