Netlist unveils additional NVDIMM modules
Netlist has extended its NVAult product line-up with the roll-out of its EXPRESSvault EV3 PCI Express 3.0 non-volatile RAM. The EXPRESSvault claims to be a novel storage-class memory tier aimed at server-side caching, scale-out storage, database and distributed file systems and all-flash arrays. It can also be used as both a block storage device or as a persistent memory extension.
Netlist’s VP of worldwide sales Christopher Lopes has revealed that the latest product line is a natural extension of its NVDIMM technology based on input from customers, providing an alternative to flash-only options or ULLtraDIMM technology. It’s not dependent on the memory bus technology, he said, and can be integrated with both DDR3 and DDR4 hardware.
NVDIMMs are persistent memory modules that reside on the DDR DRAM channel, combining volatile DRAM and non-volatile flash memory. Under normal power conditions, an NVDIMM operates exactly like a regular DRAM module. During a power failure or system crash, it is powered by a supercapacitor pack. The data within the DRAM is transferred to the flash and can be restored to the DRAM when normal conditions resume.
