back to article 'Fastest storage in the WORLD' plugged into mighty boffinry Cray

DDN claims it has sold the fastest storage system in the world to the Oak Ridge National Laboratory for its Titan superduperwhoopercomputer, shooting data out faster than 1 terabyte a second. Titan Racks Colourful Titan storage racks The Oak Ridge National Laboratory (ORNL) is a US Department of Energy facility managed by UT- …

Does it run windows 8?

No. It's running Windows ME.

Meh

They haven't sold or even delivered the fastest storage system. They have delivered 36 of their okay storage systems that were bolted together by ORNL to get those figures. ORNL could have used almost anything to get there by that method.

Re: Meh

Sort of true, but these storage systems combine to present a single filesystem (with the associated aggregate performance and capacity) so they are deployed as a single storage system.

To use the same analogy; any cluster isn't a system, it's just a collection of smaller machines.... the Top500 list is going to need some editing.

Re: Meh

@Joms - Yes, but how large a file do you have to move in order to get anywhere close to the 1TB/s rate? You're certainly not going to be getting it with smaller files,

You don't need 1TB/sec for a single small file though, so who cares if you aren't getting that speed? You could make the same argument at all levels down to striping two drives together on a desktop.

When you parallelize you can get up to double the throughput, but whether you actually do will depend on limitations in the other hardware and in the filesystem. Presumably the guys who designed this knew what they were doing in relation to the types of data they'll be working with.

Re: Meh

You don't need one large file, you can also have thousands of small files being created, written and/or read at the same time to achieve that aggregate performance... which is exactly what they've got.

Does anyone else want to cancel out the units when they see "megaflops per watt" in a story?

I wonder what it can do to the Bitcoin economy, over a quiet weekend.

MTBF

The cynic in me wonders how the failure rates across those twenty thousand drives will stack up against what is "expected." Thinking about it, I don't think I've ever seen figures like that released...
