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.

I think not.
There is quite a market for bioinformatics. My employer spends around 5 billion USD a year on pharma R+D. Much of that money is used in traditional "brute-force" type attacks of screening many compounds against many targets.
There is tremendous potential for savings through bioinformatics, and the evidence is working its way through pharma pipelines as we speak.
While there may be as much hype around bioinformatics, the field is solving a genuine problem for a mature, well-funded industry, unlike the dot-com book which speclated on products many didn't want with money that didn't exist.
Re:New Measurement System? (Score:2)
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.
Re:New Measurement System? (Score:4, Informative)
A whole bunch. One of the difficulties of sequencing the genome is that it's somewhat error prone, which requires that the same region be sequenced several times to make sure that you've gotten it right. The chunks that can be sequenced conveniently are also very small compared to the whole thing, so it's necessary to sequence in overlapping chunks and put it together like a puzzle. The combination of those things means that each base in the genome must be sequenced something like 10 times to get a reliable result. That gets you up to 10 genomes off the bat. Add in the fact that each bit of sequencing information will have meta-data (i.e. where that snippet came from, which machine generated it and when, etc.) associated with it and things fluff up even more. When you start piecing the data together it will require a lot of processing power, so it may wind up being a good idea to use algorithms that trade storage space for processing time, and that can inflate your storage needs even more.
Even once you have the genome as a finished product, you may very well want to have more than one genome available. An important, but less well publicised, part of the genome project was the decision to sequence the complete genomes of several other organisms at the same time. Those include four species particularly popular among biologists: the mouse, the fruit fly, a round worm used in a lot of research, and baker's yeast. Doing genome to genome comparisons is a very good way of finding the areas that are biologically important because they'll remain similar across organisms. As you can imagine, doing a complete chunk by chunk comparison between two 3 GB data sets can chew up a lot of resources, and having fast access to a huge memory space like that is going to make it a lot easier and faster.

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

- Simply connecting 30 PCs together in a cluster will result in a nice, fast supercluster, but it won't come close to a Cray, because Crays are designed from the beginning to be as parallel as possible.

Buy an IBM / HP / Sun top of the line, stack
it with 256GB, and you can use 224GB as a file buffer. Or 128GB, or 16 GB, or whatever you do not use for something more important.

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.
