| | Linux Kernels 2.7.* and up support 4 Petabytes Hi all just noting whilst MS is mulling over a 128 bit version of the OS, the current Linux kernel (2.7.X) supports 4PB RAM 4 Petabytes -- not that I've even SEEN a system with that much. I haven't even seen a PC with 1 TB of RAM yet. Most of us still wonder what to do with > 4GB RAM. What exactly would you run on it apart from a Big Brother app watching over every inhabitant on the planet from cradle to grave.  Cheers jimbo |

| | I need 4 petabytes of ram so my computer can become ridiculously fast with no effort on my part, and thus make me an incredibly impatient person in real life. |

Since they're running Fedora Linux, maybe they're getting ready to do some serious computing... Nice to see IBM and AMD "at work", with FORTRAN...

I believe the limit for Server 2008 R2 is 2 TB ram, but again, I don't think motherboards are available that can handle that. As the need becomes apparent, I'm sure it will be quite simple for MS to add higher RAM limits as necessary. PhreePhly |

| | Well, exabyte is not something I use often, and I didn't have the opportunity to look it up. I was just going off of memory on the theoretical RAM limit for 64-bit OS's. I knew it was greater than a petabyte, but I couldn't quite remember the prefix for the next 1000's unit above peta. Oh well, that's why I'm always learning. PhreePhly |
