    Cores and effect on Virtualized FMS Perfomance

    Oliver_Reid

      I am trying to educate myself on virtualization basics (WMWare , Parellels Virtuozzo, etc.).

       

      With 2 4-core/8GB machines seeming be a typical mid-level FMS13 + WP hosting environment I have a concern.

       

      How will virtualization environments perform handling several VMs this size? My reading suggests that a typical industry VM is much less powerful. (Or I am I just misinformed here?)

       

      How do these tools perform with several VM's (e.g., a c16 Core 32GB box with multiple 4-core 8-GB VM's) that each have much more virtual power in relation the machine's physical total? Are their advertized efficiency advantages still delivered in this situation

       

       

      I would be inetrested to hear about folks' expereince here.

          A VM instance is as powerful as you make it.  It is true that when you don't specify ahead of time what you need, a typical IT department will dimension a VM instance with resources that are too low for FMS:

          - not enough disk space

          - not enough processing power

           

          As to combining multiple virutal instances on one physical host: that comes down to monitoring to a large extent.  Setting up a VM environment is not a "fire and forget" solution.  The physical host becomes a very real potential single point of failure.  To counter that:

          - it must be very very robust with all sorts of redundancy

          - and spare capacitiy

          - and must be monitored 24/7 for singes of trouble

          - but also to see trends in usage across its VMs so that you'll know you will hit resource constraints before you actually do.

            Thanks Wim that is helpful

             

             

            In the case of FMS 13  is  there any performace impact from using, say, an 8-core processor vs two 4 core processers ?

             

             

            In a virtualized enviroment I do not see why, say, 4 Physical 8-Core E5s should perform better than 8 Quads - a much less expensive option?

              To a large extent that depends on the # of concurrent users and the design/nature of the solution.  FMS will spread the load (more users and or ore tasks generated by the users) across the processors so 8 cores is going to be much better than 4 in a busy environment.  There won't be much difference in a low usage (users and/or tasks) scenario.

                Actually I was asking about TWO quads vs ONE 8-core

                 

                Sorry if that was not clear
