zomer las op /. over een erg interessante IBM computer
Wedman sent us a snippet from a newsletter from OpenSourceIT that starts off by saying that IBM will announce a new pricing scheme for Linux on the S/390 mainframes: Soon they'll cost $125k. For another $20k you can get virtual machine software to run multiple copies of Linux on the same box. David Boyes, a consultant who works with the S/390, managed to boot 41,500 Linux servers on one mainframe. Although he notes that you may not be able to run that many in real life.[break]Na wat verder speurwerk bleek hierover meer info te staan in dit artikel van NetworkFusion:[/break] At its IBM Design Center for e-transaction processing opening in Poughkeepsie, N.Y., IBM last week demonstrated its Linux system running on the S/390 and hinted that plans are in the works to introduce versions of its software, such as the Websphere Web application server, optimized to run on mainframe-based Linux.

For its part, IBM says it's easy to run multiple copies of Linux as a Virtual Machine guest, which allows a copy of an operating system to run on the mainframe as if it were an independent server. In one test, a user claims to have run 40,000 Linux Virtual Machine guests on one mainframe CPU. IBM claims users can actually run more than that - up to 41,000. These servers can also communicate with each other inside the mainframe at 500M byte/sec, much faster than they could if they were physically separate servers in a LAN.
Dit lijkt mij nou een ideale tweak-bak.
