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
