Shoot me an email if you would like to see how I configure my Cisco
switches.
Let us know how the testing works out!

Hi Liam,
Yes that is a good point, i will have to check for that, as I will
be moving from 3com to Cisco 5500g
So far I only have 2 elderly test servers, using netperf i have
measured 1600Bbits/s which seems to be CPU limited. I will look at
the double brick idea as it sounds a good work arround.

I use balance mode0 on my gluster servers - but it doesnt exactly
work
as you would expect it too. We run Cisco 4948g switches (48 port
gigabit) and our gluster servers have two gigabit links bounded
together using mode0. Balance mode0 does a great job of balancing
outbound traffic however the Cisco's always routes each single
INBOUND
tcp connection traffic down a single trunk. So the only way to
really
gain an advantage is to use multiple tcp connections between the many
hosts - or in the case of gluster using multiple bricks per server
striped together.

Hi
I am looking at which is the best bonding mode for giagbit links
for the
servers. I have a choice of using the 802.3ad (mode4) or bonding-
rr (mode0)
I would prefer to use mode4 but this will only give a single TCP
connection
1Gbit of bandwidth, where mode0 will give multi Gbit of band width
to a
single TCP connection.
My question is, If i have 4 mirrored servers. when a AFR
replicates data
between servers, does it run multiple TCP connections concurrently
to copy
the data to all 4 servers at once, or does it do each server in
turn.
