Re: Nexcom NSA 2189L

Hey Erich,

I haven't tried it. But I thought I should comment on the
architecture. It
uses the Xeon Blackford chipset, which uses FB-DIMMS, which
run very hot.
I have 4 DIMMS, 4GB RAM in one of my personal servers, a
5000V Blackford
and the DIMMs seem to generate lots more heat than the CPU:
a Xeon 1.86
5000 series.

I have looked at the Nexcom solutions and I've been
considering getting an
8-port 1083 which uses the desktop Q965 chipset.

Anyhow, the 2189 would be nicer I think, if it used a 5100
board because
it supports DDR2. Or better yet, the 3200 series (for the
most part, 1333
MHz bus versions of the previous 3000 series Xeon boards...
which are just
glorified Conroe boards). The 3xxx Xeon boards are cheap and
the 1333
MHz/3000 Xeons are dirt cheap even at >= 3 GHz speeds.

Can you tell us where we can order the Nexcom systems from
and how much
they cost? Also, has anybody done any analysis to see if
these systems
are overkill? LEAF should not need Xeon processors, even for
24 Gbit
ports.
