CPU and RAM comparison on suse vs solaris
hi,
currently we have SAP application running on a solaris machine that has 8 dual core CPUs @ 2.4 GHZ and the performance of the system is perfectly normal. We plan to migrate the app to a suse linux VM image on a vmware box now. So my questions are:
1) Should i size the linux image to also have the same number of cores or some number of CPUs ? Or should it be more/less considering the fact that it is suse and its a VM?
2) Since this linux is a VM image, it will get VCPUs allocated to it. So lets assume that there are 2 CPUs on the physical host and these CPUs are dual core, so does that means 4 cores are shared by all the VMs on this physical host ?
3) How about memory ? any memory requirement conversion matrix on solaris vs suse & any conversion matrix of a Suse on physical vs Suse on VM.
I know i am asking too many questions. Please answer as per your knowledge and experience. thanks.
