I just received our poweredge vrtx system with two m520 blade's that are going to be utilized as virtual servers, everything is setup and good to go as far as the blade's and storage goes, however i am trying to get the networking side configured properly, and from what they say you cannot have your OOB on the same subnet as your servers will be on, problem is we are a flat network running the /24 subnet, i would hate having to go through the headache of resubnetting just to get my virtual system up.
My questions is can we totally bypass the OOB not even plug it in and setup a LAG for the 8 port 1gbe switch to our distribution switch, we are a one location shop so if i could just bring up the CMC on the server and manage the configuration from there, would that be a viable solution than trying to resubnet my network.

I'm not aware of this limitation. There is a note when configuring the interfaces that the in-band and out-of-band must use different IP addresses or be on different networks. This is to make people aware that if they program in the same IP on the same network(subnet) there will be an IP conflict.

Yes, the OOB interface is not required. You should be able to perform all management functions from the in-band interface.

i spoke with a dell rep from support that told me you could not have your OOB on the same subnet a

I do not doubt that someone told you that, but I think it is a misinterpretation of a note regarding the OOB interface. The note is intended to make people aware that the in-band and out-of-band are two different interfaces and cannot have the same IP on the same network.
I could be mistaken, but based on the way I understand networking to function I cannot think of a logical reason why they would not work on the same subnet.

They told me the reason would be you could potentially take down your network with broadcast storms, i agree with you i dont see how it would make a difference if your oob was statically assigned to a dedicated IP address on your subnet how that would affect anything, but that is what they told me

That does not make any sense to me. I suspect that this person misinterpreted the note I mentioned previously and made up a reason to justify the requirement. At this point I would suggest discarding the information that agent provided to you. I have looked through all available documentation and I cannot find anything to back up what you were told.
I have found the information you were told mentioned online in the forums as well, but it also has to do with misreading a notation on the interfaces. In our internal documentation there is a note intended to let people know the two interfaces are different and require different IP addresses OR that they be on different subnets/networks. If someone that doesn't understand you can have the the same IP address on different subnets reads that note they could misinterpret it to mean that the two interfaces need to be on different networks.
