I’m really excited about the prospects of memory-addressable flash. Moving flash closer to the CPU and addressing it as memory rather than block storage brings tremendous performance benefits, and is a once-in-a-generation radical change to system architecture. But questions remain as to how it can be integrated with today’s applications. Now Plexistor is here with a promising solution: Their “Software-Defined Memory” concept is a generic filesystem for storage, from NVDIMM to NVMe to SSD.
Memory 1 is the next game-changer from Diablo. I’ve been very impressed by the company’s offerings in the past, and this is the logical next step for them. And it ought to be absolutely killer since it no longer requires special motherboard tweaks. I expect it’s going to be huge in the cloud datacenter.
Top-of-rack flash and bottom-of-rack disk makes a ton of sense in a world of virtualized, distributed storage. It fits with enterprise paradigms yet delivers real architectural change that could “move the needle” in a way that no centralized shared storage system ever will. SAN and NAS aren’t going away immediately, but this new storage architecture will be an attractive next-generation direction!
I’ve written recently about the difference between solid-state drives (SSDs), PCIe SSDs, and solid-state memory over PCIe. But a new technology was presented to me this month that’s even more radical: What if NAND flash was placed on a DIMM for direct access by the CPU? This is what Diablo Technologies just announced as “Memory Channel Storage”.
