Let me explain what I see in plain English since my subtility is getting lost.
Pro (for new forum) argument 1:The posters saying that 'hey, this forum would be good' are stating they don't want the forum to be bogged down with consumer level IT posts.
Rebuttal: When the consumer level posts are removed, and a forum created specifically for those types of posts, it had no traffic and was dropped.
Pro (for new forum) argument 2: The separate forum had no traffic; possibly because no one knew it was there, and/or because it required a separate login.
Rebuttal: So far, it sounds like 2 out of 2 posters who wanted a separate professional IT forum knew that a separate professional IT forum existed, but did not use it. Why would those same 2 posters assume that they (and others) would use a subforum if it was made, when anandtech already gave them the chance on having a professional forum, but they chose not to use it?
The attempt already failed at anandtech. See Gillbot's response; move on with life.
You're missing an important component. This community. Yes, the majority of the community is geared toward consumer level products. I came to AnandTech years ago due to my interest in consumer level products. If you look below my avatar, you'll see that was around 9 years ago. Back then I was in my early 20's and messing around with custom rigs and overclocking and playing Counter Strike. I'm now a Data Center Administrator and while I'm still interested in consumer level products, I have knowledge regarding enterprise level products and also have questions and curiosities and seek advice about enterprise level products. I imagine I'm not the only one in this exact situation.
Anand has an interest in enterprise level products too. Hence the series of articles he's doing on virtualization with "guests" from VMWare and Intel. Hence the IT/Data Center tab on the home page.
A separate, "AnandTech branded" forum for enterprise type products which is only indirectly related to this community isn't what I'm asking for. Obviously, it didn't work. What I am asking for is a single section within this community for such topics. There is a Home Theater section here - one could argue that there are other more dedicated forums/communities for this, yet it exists here too. There's a Highly Technical section here, which is a catch all for topics that are very technical and require specific knowledge to discuss intelligently, many of which have dedicated forums elsewhere, yet it exists here too. We have a Love and Relationships section here... do you see my point? The common factor in these very different topics is the community. The AT IT Forums failed because they tried to create a new community or duplicate this community. I could have told you that would happen before it was ever created.
If the admins can maintain low traffic sections like Highly Technical, Contests and Sweepstakes and has an entire section devoted to something as specific as Power Supplies, why can't a section for IT/Enterprise discussions be created and maintained? How difficult would it be to create? How difficult would it be to maintain? What would the harm be? Even if it doesn't become as high traffic as Off Topic, if it added any value to these forums at all, wouldn't it be worth the time to maintain along with the others? This is a topic only loosely related to the main focus of the site, but so are a half dozen other sections here.
Look at the responses... there are people here that agree with me. I bet there are more that don't visit this Suggestion Box section. In fact, I know there are:

By the way, AnandTech's competitors, (Tom's Hardware) has such a section on their forums. Granted it's the lowest traffic forum on their site, but it's only been in existence for 6 months. ArsTechnica also has such a section on their forums.
