I have looked into the "Beowulf" system alot recently. It is nothing but a glorified COW design. And it uses "off the shelf" software components that run under FreeBSD as well of better than linux often. I used to thing it was a big deal. Not any more :I This is a tangent though :) > You do this on FreeBSD (or Linux or Solaris) by creating a "layer 4 > router" or HTTP switch that directs traffic evenly among your several > web servers, and stops sending traffic to servers that have failed. Where could someone find information on setting this up, and what software to use? I have someone who would be very interested in this. Isn't the "layer 4 router" a SPoF though? -- David Cross | email: crossd@cs.rpi.edu Systems Administrator/Research Programmer | Web: http://www.cs.rpi.edu/~crossd Rensselaer Polytechnic Institute, | Ph: 518.276.2860 Department of Computer Science | Fax: 518.276.4033 I speak only for myself. | WinNT:Linux::Linux:FreeBSD To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
