Question

1. so if i wanted to build a linux server for web services(apache) with 1cpu and 2 gb of memory.

-operating at 75% of memory capacity

2. a windows server with 2 cpu/ 4gb memory
- operating at 85% of memory capacity

3. a storage server with 1 cpu/ 2gb memory
- operating at 85% of memory capacity

how much memory do i have to add for each server.so that the utilization rate for both cpu and memory is at a baseline of 60%.
"the details for the cpu like its processor or the memory's speed isnt to be concerned" yeah i kept asking my teacher if he's even sure about the question... but the whole class seems to be confused and the project is due in 3 days..
this is a virtualization project where i have to virtualize a typical server into an exsi hypervisor.

Answer 1

The minimum memory requirement for a linux server running apache is 1GB while a Windows server is 2GB (which is a joke.)

Realistically I recommend 4GB for the linux server to handle the occasional spikes for web services and 8GB to 16GB for the Windows server.

The memory requirement for a storage server is not very high. To keep the utilization below 60%, it can be upgraded to 4GB which should be plenty.

Answer 2

1. linux is a relatively light-wt OS so it doesnt require lots of memory. but it is for web service so its work load may vary greatly due to demands. its better to have more memory. add 2GB for a total of 4GB

2. windows is a heavy OS n requires loads of memory. to run a windows server, it needs at least 8GB n may be up to 16GB to be on the safe side

3. storage server does not require much memory either. if u want to lower utilization from 85% to 60%, add 2GB for a total of 4GB
