What the Heck is an IBM Cognos PVU?
A PVU (Processor Value Unit) is a unit of measure used by IBM to determine the usage on the server. Technically, a PVU license is assigned to the Analytic Server, meaning there is a cost per core processor. Simple enough right? Not so fast. The PVU value assigned to each core depends on hardware. Not all core processors are treated alike. It’s kind of like being taxed a little higher for a luxury automobile, the better the performance the higher the tax. A server’s PVU count is defined by the brand, model and number of physical processors running in the server and the number of core chips per processor. In order to calculate the number of PVUs, it also is necessary to refer to IBM’s PVU-per-core ratings for current processor technologies, which are updated on IBM’s website here .
