Novell vs. NT (AREV Specific)

I posted this question a while ago and haven't gotten a response. I'm interested in hearing what Revelation has to say about this…
We are planning to install OpenInsight to allow client access to our Arev database via the web. We are running on Netware 4.11, and were planning to move Arev to an NT server running OpenInsight (we've been told that Arev and OpenInsight should exist on the same server). Our current users would still access the Arev database, but continue to log in through our Netware 4.11 server. We heard that if the local workstations were running both IPX and IP, there would be a speed decrease when accessing the Arev database. How much of a speed decrease are we talking?
We then talked about upgrading to Netware 5 so we can run straight IP from the local workstations and access Arev on the NT server without speed decrease. Then I noticed a discussion about the LHIPXTSR NLM, and as I understand, the workstations will still have to run IPX?
Yet another scenario – if we upgrade from Netware 4.11 to NT, will there be any performance issues?
Any insight or recommendations would be appreciated.

ARev and OI only need to be on the same type of server if you are planning on sharing data. This is to ensure that locking works correctly. If you use just the NPP (no NT Service) or the byte range driver, they can be on any type of server.
If you set the bindings up correctly, then there should not be much of a problem. The problem happens with the OS (usually Win95 or 98) does not know what protocol to use for communication so it tries to figure it out for each request.
If you plan on staying with Novell IPX must be loaded.

Not sure we follow. If ARev is on the NT server, then moving to Novell 5 will not do anything speedwise since the database will reside on NT.
Most likely you will notice some slowdown when moving to NT. This is because Novell is simply a faster network.
You'll receive even more slowdown if you start mixing protocols. The best thing to do is stick with one network type.

One of our goals was to try to decrease the number of protocols used by the workstations. We planned on upgrading our file server to Netware 5.0 and move our AREV/OpenInsight database to an NT application/web server with the NT Service loaded. So the workstations would log into the Novell server first and have a drive mapping that would attach to the AREV database (on the NT Server). If our database existed on the NT Server and we upgraded our file server to Novell 5.0, would we still have a need to run IPX on the workstations?
The NT Server will also be a web server that will allow our clients to see "real time" information from our database. Is it a good idea to have the database exist on the web server? This is the same database that our users will connect to.
Any comments or recommendations are welcome.
Thanks for your response,

No. With this configuration the Novell server would just be another server on the network. AREV/OI would only care about your NT connection.

As long as you want or need user to access real-time data then the database must be visible to the web server. That means you could store the files on the web server itself or have the web server pointing to a mapped drive on another machine. How you configure this depends on your security options/needs.

It is a seriously bad idea to have your data on the web server - this is a security nightmare. The idea is that if a hacker gains access to your web server they could get at all of your information and possibly corrupt/damage it. You need to be especially careful of providing the anonymous user with supervisor rights as anybody hacking into the server from the web could thus gain supervisor rights against the machine.
