Cray's New Solid State Storage 382

Sivar writes: "Cray, a well known vendor of extremely fast supercomputing hardware, has introduced a storage system with a 224 GB capacity. The large size seems impressive, but the device can also transfer an unprecedented 80GB(!!) every second. That's more bandwidth than the main memory of most servers, and it's just for storage. For comparison's sake, a typical dual channel DDR motherboard has a bandwidth capacity of barely 4.2GB/sec." Yow.

    • why use any RAM at all? That would be an interesting turn of events, wouldn't it? As a matter of fact, that might be an actual Paradigm Shift in computer architecture.

      • Back in the 60's, non-volatile magnetic core memory was used instead of RAM. So the idea of non-volatile memory is actually very old.

        With virtual memory hardware, you can write an operating system that simulates non-volatile main memory, using hard disk as a backing store. What you get is a Persistent Operating System [arizona.edu]. You don't need a file system. Instead, you store data structures in main memory, and they persist forever, surviving reboots.

    • Too many context switches makes your system go dog slow. While the transfer rate is extremely high, the latency of talking to a piece of storage that is perhaps several feet away, at the speed of light, is too high.

      The RAM gets stuff from the hard drive.

      The solid state machine won't act like faster memory, making cache misses cost less. It will act like a faster hard drive, making page faults cost less. Using this stuff as a substitute for RAM will slow down your computer unless you have it hard-wired into your system's bus in place of RAM.
    • Um, not with any current OS or standard PC hardware. If it treated the SSD as a hard drive, it would insist on transfering everything into those 8MB before operating on it. So you'd beat the hell out of your 8MB of RAM, and you'd be doing it at RAM speeds, not 80GB/sec. In this completely hypothetical setup, it would definitely be faster to have more RAM. No PC could probably connect to this device, let alone exercise it.

    I guess that using standard measurements (GB and GB/sec) just isn't intuitive enough! But why use the humane genome as a reference? Is that REALLY more intuitive to most people? Does anyone (besides geneticists) really understand how much information is in the human genome?

    • that is the absolute worst reference "unit" I've ever seen! Depending on how you define "human genome" it's anywhere between several hundred MB to several hundred GB. Can we just go back to the more reliable and accepted units, like the LOC (Libraries of Congress)?

      Of course most non-biologists don't really understand just how big the human genome is. That's why they're using it as a reference. The genome is actually smaller than many people think (about 3 GB at one base per byte, but trivially compressible to 1/4 that), which means that expressing things in terms of the genome is a good way making your equipment sound more impressive than it actually is.

      No moving parts, you can look at this like a "big ram disk" exept it has it's interface like another storage device. Look at this like A compactflash for example (it's not "SSD" but it's a good comparison.

      There are a lot of interfaces (PCI, ATA, SCSI, proprietary (80GB/sec is either a big aggregated pile of raids or something similar) for these "drives" at various price points. The advantage of a SSD drive on a PC is that you have instant access, and it moves the stuff at a lightning speed limited only by your bus. Let's say you run a SSD drive on a Ultra160 interface, what you'd probably see with a disk benchmarking tool is 100nS access time (versus ~10ms for a standard drive) and you could see the real-world numbers of your scsi bus, probably around 140MB/sec (didn't try one on a U160 bus). The application for these babies are numerous: instant access to data on boards that don't handle 100GB of ram to cache everything or you wanting the machine to preload 1 hour at every reboot, bandwidth hungry application (although a raid could do the same here, but I saw some specific application needed both the bandwidth and under 1ms access time needed so..), for heavy swapping of numbers without using a buttload of ram again, etc.. probably some other people could think of something other. Usually when you break a certain amount of GB, the drives becomes cheaper than a motherboard that could handle a load of ram and the ram modules themselves, so it makes more sense if $$ is a factor (but still it's very expensive, we're talking 10K+ easily for a few GB).

      There's also plenty of product on the net (search google), like I said, some are PCI cards that you add to your system with PC100 ram on it, some are IDE/SCSI, etc.. But for home people, you'd be better off with a cheap IDE raid card and a few drives, it's way cheaper :).

    - Crays do not run Windows. Crays do not run Linux. Crays usually run UNICOS, a special *nix designed specifically for Crays.

      Not really - consider SGI's servers, for instance. The Origin 3800 can handle 1 TB of RAM -- but it's a CC-NUMA machine, meaning you have to go through an intermediate router (don't think Internet; much faster) to get to the memory. SGI machines have a limit of 8GB per processor "brick", and their bricks interconnect at 1.6 or 1.2GB/s.

      Then consider the SunFire 15K - it's an SMP machine; processors fit on boards that can contain up to 32GB of RAM; after that, you have to go off-board through a switch to get to other memory. Each system board has about 9.6GB/s of offboard memory access speed.

      In short, Cray isn't tooting needlessly - this is impressive bandwidth to the memory. Latency is probably fairly high on it, but for streaming vast quantities of data in and out of local storage, it's probably amazingly nice.
