Hello! There are going to be a lot of ideas on how to do charging all the way from "we don't charge back" to "we charge by the micro-process".
Fixed-price charging is good for very well contained zLinux servers. Using SHARE ABSOLUTE and even CPU POOLING can help with this. CPU POOLING is really good if you are thinking of mixing those fixed-resource servers with high-performance or "premium services" servers. There are pros and cons to fixed price charging. A pro is it is MUCH easier than any other kind of charging (other than no-cost!). A con is that some folks may think they are being charged too much if they really don't use it that much or that heavy, and some may not be thrilled being capped when they want to run something heavy for a short while. We use a variable rate based on consumption for most of our servers. We also have "lab" servers that are contained within SHARE ABS. We have processes to "cap" non-premium production servers when they get out of hand and the entire processor has been running in the high 90's for CPU. We use zVPS to collect all the data for the processor/LPARs and the zLinux servers to evaluate what they are up to every minute. Using that data, we are able to charge-back to the business units based on what they consume by process/application. There is a small base charge for just having a server, then the use of resources adds to it. This was all built over the last 10 years and we are still tuning it! Figuring out what your business will accept for charging is the hard part. Between the knobs in z/VM and performance monitoring/collecting tools available, you can make it work the way you need it. -- *James Vincent* -- President, SHARE Inc. -- Calendar: http://tinyurl.com/JSVCalWeek -- SHARE is an independent volunteer-run information technology association that provides *education*, professional *networking *and industry *influence* On Mon, Feb 23, 2015 at 2:10 AM, Agblad Tore <[email protected]> wrote: > This seems to be the biggest hinder for most people to start using Linux > on z. > Anyone having done this ? > There is a number of options to limit cpu and resources, SHARE and setting > max memory for example.
