Hello list. It is a well-known fact that speeding up the OSD journals results in overall performance improvement. And most installations use SSDs to gain this benefit.
But is anyone using or considering using NAND-backed DRAM like the Viking ArxCiS-NV and similar NVDIMM solutions? I think these will be even faster - eliminating the disk/PCIe bottlenecks - and more performant given DRAM's order of magnitude speed improvement. Who knows, with the entire system memory consisting of "non-volatile" RAM, maybe we can even turn-off the journal and count on the OSD filesystem caches to writeback to disk eventually? What do you think?
