World data transfer record: 186Gbps

Yip, the HDD wouldn't keep up.

Wondering what they used as test data. Sure sure it was raw data... (cough cough blu ray movies cough cough)...
 
Well technically the hard drive would only need to read or write at 98gbps, which I think translates to 12.25gigabytes/sec.

The fastest SSD's do about 500 - 600megabytes/sec, so yeah you'd need to raid0 quite a few to get that kind of throughput :D

I wonder how they actually do it in terms of local storage, nevermind the WAN infrstructure.

na i think they doing it with something like this raided PCI-EXPRESS SSD cards.. most likely a raid
config like RAID 100 (RAID 1+0+0) or something

you can get burst read/write speed of up to 1.4GB/sec

I don't think they sent any meaningful data. Just used a special NIC that sent streams of binary sequences. No hard drive or even CPU involved to create the data.

This does make the most sense.

nope it was actually done via memory to memory transfer.

http://supercomputing.caltech.edu/showfloor.html

During Super Computing 2011 a small team from Caltech, and University of Victoria transferred data from disks at the University of Victoria to disks at the show floor at more than 60 Gb/s (Gigabits per second). This is believed to be the fastest disk to disk Wide Area Network data transfer to be achieved at Super Computing 2011. In addition the team was able to move data from memory to memory at over 98 Gbit/s and receive it using only 4 machines on the show floor. Throughput of this magnitude would have required dozens or hundreds of high performance machines only a few years ago. The team was able to sustain indefinitely a total bidirectional memory to memory data transfer of 186 Gb/s. The demonstration showcased the performance possibilities of cutting edge 40 GE network cards combined with PCIe Generation 3 servers with solid state disks. During the course of the SC11 exhibition more then 4 Petabytes of data was moved between the two sites
