Citrix Server accessing SQL Server through 2nd Nic.

Hi All,

Hope you can give me some advice here.

I am currently running SQL Server and Citrix Server on Separate servers. The
Citrix and SQL server are connected to the 10/100 switch and the Local and
Citrix clients access the database though the Fist Nic <Gig> on The SQL
Server. The second Nic on the SQL server has been disabled.

However I am thinking of allowing the Citrix Server to access the SQL server
through the 2nd Nic and remove the Citrix Server connection to the 10/100
switch.

Will this increase the network speed for the local users and will it
increase the speed for the Citrix users? Will this be advisable?

If so, how do I configure that the local users use Nic1 <Gig> and the Citrix
Server use Nic2 <Gig>.

Thanks
Chris

Probably not.

Probably not.

In my opinion, such designs are never recommended, at least not from me.

Make sure that there is only one path to the SQL Server (only one nic in
it). Access the SQL by IP# only. But, like I said I don't recommend doing
it in the first place,..it will always turn into a "can of worms". There are
ways to make it work but it will always come at the cost of something else.

The best approach is to just simply use Switches instead of Hubs, which I am
sure you are already doing anyway. Switchs never let one traffic session
with one pair of hosts "share the wire" with the with a different session
between other hosts.

The only "shared" wire in your case is the cable between the Citrix box and
the Switch because it has to use that same cable to talk to both the users
and the SQL Server. But this being a gigabit link...it will do fine. The
rest of the LAN is unaffected because you are dealing with "directed"
traffic, not "broadcast" traffic. "Directed" traffic always has its own
"logical circuit" via Switches so host that aren't part of the conversation
never even see the packets,...the packets must be broadcast or multi-cast
before any other hosts will see them.

The purpose of routers and subnets on a LAN is to protect from "broadcasts"
and that is not what you are dealing with here.
