Depending on the size of a network, you could be talking about a few pieces or a few thousand pieces. Many of the pieces look the same, they smell the same, and they have names that often sound the same. It's all an elaborate hoax, because almost everyone one of those like sounding boxes does something just a little differently than every other one.
Just so we're all on the same page, we don't go through every piece of network equipment in existence every time we design a network for a client. It just isn't worth the time and effort to anyone, so we've filtered down the list to the equipment we like to use. Equipment that we've used before, and that has worked for our clients. The vendors we recommend make wide varieties of equipment, enough to cover just about every situation.
Network design is an art form. No two networks are the same, and no two companies are trying to do the same thing, or protect the same information. Here are a few things to think about:
Because we are not a retail operation, our primary revenue stream is not dependent on "moving product". This allows us to be unbiased in our recommendation as we have no financial stake in the equipment choice. There are lots of major vendors which you will not see on our website. Some of those vendors demand that you recommend only their products, or they will not allow you to participate in their programs. We choose not to represent those vendors, as it would force us to choose equipment that is best for the vendor rather than our client.
When we make a recommendation, the basis of that recommendation is what's best for the client, and only the client.
