IBM acronyms

There are many... But these are the ones I hear and need to remember: DAU - Demand Acceleration Unit (Early release machine that IBM sometimes gives to customers to evaluate.) BMC - Base Manufacturing Cost (Cost for parts) TMC - Total Manufacturing Cost (Total cost including labor) VLH - Vendor Logo Hardware - Hardware that we resell that still has the vendor logo on it. MES - means an upgrade to a system, but I don't remember what it stands for.
