Gravity generator. The speed of gravity is still unknown, but might be very very fast, and will enforce low-latency and cross-barrier transport across continents. I don't think, however, you can find a gravity generator in the commodity market. Not sure if you can find any at all :-)</div>

Hi,<br>
<br>
Here is a theoretical question:<br>
<br>
Lets say I have a Linux server in Israel, and I have a block of storage<br>
(lets say iSCSI partition for this example) in USA, and I want to mount it<br>
on my server in Israel.<br>
iSCSI over such a long distance and with big latency (thanks to our ISP's)<br>

<br>
Not sure it's mainly the ISPs, BTW. You do also depend on the physics of<br>
speed of light.<br>

<br>
If you use IP over nutrino-based transport you might be able to shave a few nanoseconds off the speed of light, see this: <a href="http://www.wired.com/wiredscience/2011/09/neutrinos-faster-than-light/" target="_blank">http://www.wired.com/<u></u>wiredscience/2011/09/<u></u>neutrinos-faster-than-light/</a><br>

I can take this storage, format it and export it from my server in USA, but<br>

Do you need it read/write on both sides? If so, you are going to have<br>
big problems if the link is cut.<br>

2. Can work with long distance latencies<br>
3. won't "kill" the machine if the remote directory is disconnected /<br>
"disappeared"<br>
4. If possible - supported (either directly or using 3rd party driver) on<br>
Windows 2008 (Linux is the main concern, Windows is optional)<br>

I used drbd on a LAN, and know that it can theoretically work rather well<br>
on larger distance when used as read-write on one side only. They also<br>
have a pay-for tool to do this asyncronously called drbd proxy. This<br>
implies using a local copy and have drbd sync it. You can choose between<br>
three what they call "Protocols" to affect the perceived local latency.<br>
