Hi,
After the GNA machines are moved to the new location, they will
be plugged on a gigabit link. The cumulated bandwidth of all machines
on our switch can occasionaly require more than 100Mbs (as little as
10 people downloading a large file at the same time from an ADSL2+
line for instance).
I occasionaly noticed that lisa.gna.org was not serving as much
as it could, even when its load average is low. Anyway, nowadays 100Mbs is
just not enough when millions of developers have 10Mbs in download.
I'll buy a gigabit switch and a few gigabit ethernet cards.
I'll be thinking about the ratio between maximum bandwidth (100MB/s) and
the average capacity of a IDE/SATA drive (between ~20MB/s and 40MB/s
and 20MB/s is a safe conservative number.
It may be a good idea to have a SCSI machine for serving data
since the limit is rack space and power. Let me know what you think.
Cheers,
