back to article We can give servers more memory, claims Diablo. Well, sort of

Diablo Technologies has launched its Memory1 flash substitute for DRAM, which, it claims, gives servers more "memory", enabling one server do the work of ten, saving on power, cooling and rack space, and threatening to slash server sales. Its Memory1 products are all-flash DDR4 DIMMs developed from its existing MCS (Memory …

    Actually, this seems like a good use for (very expensive, but still cheaper than DRAM) 3D XPoint chips.

    Why volatile?

    I think these are a great idea, but why are they not non-volatile? This just makes them a slower, cheaper RAM. Why not make them non-volatile and allow them to be used "as a disk"?

      Re: Why volatile?

      The Diablo MCS storage that SanDisk uses in its ULLtraDIMMs is non-volatile. I'm guessing that Memory 1 drops the backup power circuitry that protects again incomplete writes in the event of power failure.

    At least two points the advertisment (disguised as an article) misses:

    1) NAND is very, very slow compared to DRAM so what's the point of in-memory database if it's not (significantly) faster than same DB based on SSD or similar, much cheaper option?

    And volatile to boot, which SSD, based on same technology, isn't.

    2) How many times you can write to these NANDs before it's time to replace the chips?

    On hard drives this isn't a major problem but NAND as a memory it is.

    What specifically is the market growing from $4.3b to $18.9b?

    Is that Server DIMM/LRDIMM, PCIe cards, MCS cards?

    Interesting innovation. Diablo is doing some great stuff. Surprised they are still private or not IPO'd.

    Seems like quite an expensive NAND

    Quick math its $5/GB, you only get max of 1TB NAND per server

    And proprietary/non-standard stack

    This is when NVMe drives are gowing below $2/GB, can hold more than 4TB per drive, and come with standard stack and a growing eco system

    Diablo need to come with innovation on how to combine dram and nand, and lower the cost quite a bit to make it interesting

      Re: Seems like quite an expensive NAND

      Netlist's HyperVault product, which is forthcoming in late 2015, supposedly combines DRAM and NAND in a single card. I don't know of any other products doing this yet. 3D XP sounds like it may do this in the future.

        Re: Seems like quite an expensive NAND

        Also, would add NVDIMMs do this too, but mainly for backup and some other functions, not really to use NAND to behave as DRAM.

      Re: Seems like quite an expensive NAND

      If you want to comparing memory channel storage with NVMe, you have to look at the lower latency it offers, there a more to it than just $/GB, and Diablo claim 4 TB in a standard 2 socket server, not 1 TB.

    Holy hell

    There are still Netlist shills.

    Will you people let it go? You lost. Do you really need to drag your sorry, wrecked egos through the mud again, chasing after Diablo jumping up and down trying to lash out? FFS, just let Netlist crawl into a corner and die with whatever pathetic shreds of dignity it has left.

    You hardcore Netlist believers are about as crazy as the two people who believe SCO's bullshit and try to convince the world of it. Find a new religion. Yeesh.

      Re: Holy hell

      Who said anything about the Netlist-Diablo legal events.

      I am simply responding to the inquiry about combining actual DRAM-Flash.

      Also, is Carbon2 still on the roadmap or is Memory1 effectively that?
