Does using different nic cards

By gazza7 ·
We are about to buy some new pc's for our network. We are currently using 3-com switches which has a gigabyte link. I was told that if we don't use 3-com nic cards in the new PC's it will affect performance. We are currently using Intel pro cards, which where already in our older PC's, before the switches were installed. Will using differnet nics affect performance off the network??

Not only will using Intel nics not negatively affect performance, it's likely you will be better off.
We use 3com switches and a combination of 3com Intel and others for our hubs and nics. It has been our experience that 3Com has some reliability problems regarding noisy chips and auto negotiation.
At least in our case Intel nics, both server and workstation types, have performed flawlessly. Of course if your Intel pro cards are 10T only then you may want to upgrade them to 10/100 types.

I would be very surprised if anyone could actually produce any data showing that a 3Com switch works any better when used with a 3Com NIC.

Overall, I've had better experiences with Intel and clone NICs than I have with 3Com, regardless of whetherI'm connecting to a 3Com switch or a Cisco.

Here's your answer:

There will be no difference in wire speed between a 3Com NIC, Intel NIC, LinkSys, NIC, etc. However, there are some differences between the NICs that you must consider.

1. 3Com has consistently developed better performing NICs than most other NIC manufacturers. Things like Parallel Processing and management capabilities add value. Parallel Processing doesn't cause the wire speed to be any greater, but it takes a certain amount of load off the client workstation and allows a more robust communication between a client and a host. It is 3Com specific but does NOT require the use of 3Com hubs or switches.

2. 3Com has some pretty cool management tools for their hubs, switches, NICs, etc. If you use these tools, you will want all of the devices on your LAN to conform. Tools exist to monitor the performance of an individual NIC in a PC. It's very convenient to use one set of tools to manage your hubs, switches, and NICs. You can also implement Wake on LAN if you choose.

3. 3Com has developed some bonding capabilities and fail-over cabilities into their drivers that support a 400Mbps link between a server and a 3Com switch. Or, you can use this capability to install 2 identical NICs in a server that automatically fail over to each other if one of them stops working.

So, the bottom line is this: wire speed performance is determined by standards. But, individual component performance can be enhanced through technology. LAN management can be simplified through tools, and some proprietary functionality can be achieved by using components from a single manufacturer.

Since Ethernet is a "standard", obviously all Ethernet products should play well together. Although Barry is a 3COM flag-waver (and 3COM products are generally, just fine), I don't see much in his reply that couldn't be said about Intel and their products. Intel has some very interesting server NIC solutions with onboard processors that free up the server processor quite well. Check out their website, http://www.intel.com/network/products/desktop_adapters.htm?iid=netsite+inc& for desktop NICs and http://www.intel.com/network/products/server_adapters.htm for server NICs.

No it should not affect the performence fo the network. BUT I have found that if I use components from the same vendor it is easier to configure a system and troubleshoot when a problem occours.
ie: I don't have to deal with Tech support from one component trying to pawn off the problem on another vendor's component.

In your scenario, you already have NICs in place, so it would be wastefull to replace them with 3COMs. In the future, I would just add 3COMS to any new systems that will be added to the network.
