My idea is/was, to put the PPPoE server diretly byside the FTTH DSLAM's, which mean, each 96port DSLAM has an upstrem of 1 GE and even if I put 10 of them in a 42RU, it would normaly not fill the 10 GE ports of a professionel Server. And of corse, I can put always two or three together parallel. The problem is only, that I can not install 10 (or 20 redunant) 1U Sun Fire X4100M2, even if I can get up to 60% rebat of the listprice. I have not the place to put 20 additiona servers into, nor I like the power consumation ~70 Watt with the smalles CPU and only 4 GByte of RAM. > Yes, you may find that having two small boxes Your two small boxes are at lleast 10 servers with 1U supporting 10 GBit in summary or 20 if redunant.

If I go with 1 U Sun Fire X4100M2 the Opteron has 4 Cores and 4 threads per core (AFAIK there is a 8 threads version too) >> Can you recomment it for an ISP setup? > > It's FreeBSD running from a read-only mounted medium. > No more, no less. Yes, it's fine for an ISP setup. If I have 4 GByte of memory, I could run entirely from RAMDISK...
