PPPoE server (high traffic in WDM network)

[Michelle Konzack]

Hello,

I am using since over  10 years  Debian  GNU/Linux  and  3 years  longer
NetBSD. Also I have a running PicoBSD box.

Now I have a problem more grave...

I am ongoing to install a CWDM (1GE) and DWDM  (10GE)  network  for  the
Alvarion BreezeACCESS VL (38 base stations) and more then  200  Iskratel
FTTH DSLAMS of 96 ports (each with 100MBit, but only one  1GE  Upstream)
each.

What I now need are a PPPoE Severs (round-robin and loadbalancing) which
must work using FreeRadius and PostgreSQL.

There was someone on the <debian-isp> which  has  suggested  me  to  use
FreeBSD, because the PPPoE it is already build to  authenticate  against
Radius.

So, what I like to know is, if I have a 1GE and 10GE network,  how  many
clients can  one  PPPoE  Server  handel  and  what  are  the  CPU/Memory
requirements?

There is a little problem to get small but  reliabel  Servers  with  TWO
10GE interfaces.

I think, consumer mainboards are not suitabel even someone told me under
Linux, I need 2 MHz CPU-Speed and 2 MByte of Memory per client...

Please note, that I am ongoing ISP with over  150.000  customers  in  DE
between Freiburg and Karlsruhe (Baden-Württemberg)  and  using  consumer
mainboards is NOT reliabel since in the last 6 years I lost at least  20
per year in 280 Low-Cost Servers.

A "Sun Fire X4100M2" would be more reliabel... but even the smallest CPU
would be overkill because the machine has only 1GE interfaces.

Any suggestions?

Note 1: Even if I use a Sun Fire, I would prefer a microBSD
        running from an industrial SD/CF card.

Note:  Please do NOT CC me, I am on the list and read it...

Thanks, Greetings and nice Day/Evening
