You are only a "Dell sales rep" in the loose sense that you are [re]selling Dell hardware (as a middle-man/third-party). You are not a real "Sales Rep", who is an employee of Dell that is the liaison between the customer and the assembly teams, who can make these types of configurations happen.  Call Dell, ask that a Dell Sales Rep or Technical Account Manager be assigned to you, then tell them what you need.  As long as it is technically possible on the hardware, they can configure to your needs.
I'm having a BIG problem with the Dell online config/quoter for either 11G/12G servers and storage returning ridiculous errores, i've tried fuiortlessly to tweet the dellcarespro that was like talking to a wall of pre-canned responses... This are the issue that i hope will be fixed URGENTLY as i have no time and i have quotes to build: Take the configurator link: [URL] 1) the configurator/quoter DOES NOT allow selecting different kinds of drives on the same server!Let's say i want to build a server with tiered storage with  2 or 3 array sets: 2 cheap sata for OS, 2 NL-SAS for backup and 4 15K SAS for performance.Try to enter that in the configurator and it will tell you all disks need to be wither SATA HDD, SATA SSD, SAS HDD or SAS SSD! WHY?!?!?, i want to configure the server with whatever drives I want/need! 2) Array options restrictive: why isn't there a NO RAID OPTION that lets you chose whatever PERC controller you want?, if you select no raid you end up with S110 soft raid or a H310!, this option alone should solve ALL the problems! 3) I want to configure a server using the much-mentioned cachecade feature, BZZ WRONG!, you CAN'T because of 1, the damn configurator does not allow you to select a single SSD(be it sas or sata) for cachecade!, so one of the HUGE new features advertised you simply CAN'T use it because there's no way to config your system for it!, ridiculous! Also, let's say a more standard approach, HDD+fast SSDs as different arrays for DB tiering, again i can't do it....  The configurator as is is complete rubbish!, the twitter responses where "you can't mix types in an array"(i KNOW that already and it's irrelevant) and to "call to order". Well that's not a valid option, i want to build and quote my system FAST and efficiently and not be on the phone for 40 minutes (i'm a Dell partner and i need to build the quotes to extract the config and then send them for quotation to Dell itself) and i'm pretty sure they wont' understand my requests. (as a side note, i never had this problem with HP, i built and ordered equipment/parts however my customers required to precise specs without fuss thanks to the incredible HP SP# system because when i needed something i simply ordered it without any rubbish config nagging) How am i supposed to do business with Dell when i can't configure a server whoever i need it as?
Cannot quote server storage as desired
