Hi [NAME],   OEM PowerEdge usually cater to companies that they would like to have their own brand, customize firmware to their environment requirement and customized configuration. I'll basically go straight to you questions: Here's a simple article back in 2011 on OEM branding: [URL]   Let me know if that clears the air for you.
I recently purchased a Dell PowerEdge R720 and ended up receiving an OEM XL R720.  I have three other standard R720s, but this is my first encounter with an OEM XL system.  I'm debating if I should send the unit back as the fact it was an OEM XL wasn't disclosed.  Before I do that though, I want to better understand what I'm dealing with here. I haven't been able to find much documentation on the topic, so any help will be greatly appreciated. Thanks!
Differences between OEM XL R720 and standard Dell R720?
