As someone that often has limited time to research viable options to present to leadership, I expect to be able to negotiate pricing at the enterprise level if we want to move forward. What's deeply frustrating that keeps me from sometimes mentioning an option is having no idea what the rough order of magnitude pricing is. Some kind of pricing is deeply appreciated.
If I don't know whether something will fit within the approximate budget for the project and can't quickly get an idea from other research I'm not going to mention it as an option. I'm used to spending about a million per rack but that's for a complete ESX cluster with storage and networking, if I have no idea how alternatives stack up against that it's hard to put it on the table.
