Team of 85 software game developers, the active directory, email servers are
all based in the international data centers. The production teams also link
into central asset development servers and database servers where each and
every night a 'get latest' of the latest project code (and assets) needs to
be done, this can be upward of 20gb per 'get' and will have approximately 3
hours processing time once its arrived on site as its compiled. This
production get process is done about 10-20 individual times each night.
The connection also has to be able to cope with realtime messenger style
file transfer between the developer collaberation sites.
The 'get' and local processing and the import back into the database/asset
servers needs to be completed before people start for the day.
We were having trouble getting this fitting going across our gb LAN never
mind across the WAN connection.
Paul.

Yep.
But all too often there is a world of difference between what 'actually is
the case', and what the non technical client perceives as 'being the case' !
In this case, their perception is very different to reality, but they are
not going to believe me, no mater how I tell them, as they perceive 'me' as
being the one who has solved there initial problem, by getting rid of there
much dearly loved 4 nic redundancy.
Such is life !
As a side note, I'd really like to know how a company of 109 people
justifies a 56Mbit frame relay internet connection, that's a very thick
internet pipe for just over 100 people !

This is stupid; four single-port NICs are no more "redundant" than two
dual-port NICs.
If they're that anal, it's time to scale their server out.

HP Field service has swapped the 4 single port Nic's for 2 dual port ones. 1
fibre, 1 gigabit. Some 3rd level support guy put an entry in the call log,
that this is a know issue, and to replace with dual port nic's. I'm trying
to get more details on exactly what the issue is.
Removed to old nic's from the teaming, added the new dual port ones to the
teaming, rebooted, everythings working fine. all 4 nic's are connected and
traffic is flowing on all 4 links. Quite happily fails over to the other
link when 1 is unplugged, and will switch back and forth.
Now the client is not happy, they see this as 2 single nic's and that they
have lost redundancy, and they now have 2 single points of failure, which is
probably partially true.

If it is working when cords are unplugged, it is getting confused about
which route to take, so look at your teaming settings first.
I don't have one handy to look at, but I recall there being a few different
ways to set up the teaming. I had mine set up to use the same MAC, same IP,
but I don't recall what setting I used for load-balancing (I think it was
fail-over).
You also need to set the same style of load-balancing on the device it is
plugged into...

NLB is definately disabled.
The setup is currently running fine in production with 2 nic's unplugged,
but I have been left with the task of solving the issue.

ISA doesn't know or care about teaming, Q-tagging or any other layer-2
protocols.
Make sure you don't also have NLB enabled, as NLB and teaming is not a
supported combination.

Hi,
Currently working on a brand new server, it a new HP proliant, quadriple
nic'ed.
It's running W3KR2 with all updates to date applied, domain member, all
HP updates for the HP software applied, nic's have the latest firmware
applied. it's using the HP server nic teaming software. ISA2004
installed with all updates to date applied.
The Internet connection use 2 gigabit nic's teamed to connect to a 56M
frame relay connection via a watchguard firewall (Let's not get into the
watchguard discussion, I have to work with what the company has in
place) , via cat5e cable.
They are 4 separate nic's and not dual ported ones.
The LAN connection uses 2 fibre channel nic's teamed to go to a dual
redundant cisco switch.
Before ISA was installed, teaming was working fine, both the internet
and the lan were accessable.
After installing ISA, neither the internet or the LAN is accessable,
unless 1 of the teamed nic's is unplugged on both sides. i.e. 1 internet
nic unplugged + 1 lan nic unplugged eerything works like a dream.
But plug either or both of the 2 that were unplugged in, and neither the
internet nor the LAN is accessable.
Disable the firewall services, and reboot, everything is fine with all 4
NIC's plugged in.
HP field service have been twice out replaced the nic's, ran diag's and
they are pointing the finger at the ISA server. Saying it's not
compatable with the HP nic teaming software, but can not point out any
documentation to support this. Searching the internet also drew a blank.
The company configured the server using the proliant configurader, so I
am assuming that everything is compatable, and the field service people
responded in the afermative, when asked is everything compatable.
Does anyone have any experience or suggestions on this ??
Glenn
