Question

A developer approaches you and is worried that one of the applications will not perform at peak level due to the virtual machine storage and networking.

Describe some of the tuning practices for VM storage and networking. Which one of the practices is the most important for optimizing the storage capacity? Why?

Answer 1

Practices for VM storgae and networking:

The storage and networking in Virtual machines is the new thing in rhe software industry which can ease up things for us but if it is implemented wrongly then can turn out to be very difficult for the programmers. Below are some of the practices that one must follow in order to do effective virtualization

• First of all the best practice is to always enable the Hyper-V integration services making it easy to represent a suite of special drivers and utilities which are being used in designing and improving the guest operating systems.
• Next we must always keep in mind that we make used of fixed VHD files. Using VHD files makes it easy for the fixed sized disks and the dynamically growing disks perform better and also becomes important for the servers which comes across high traffic or disk activities.
• Configuring the size of the paging files is also important while dealing with the virtualization. Pagefile.sys is the paging file available in windows that can alter the paging files and manage them in the memory to keep files organized.
• One must also not create too many of the virtual network switches as it can easily cause processing overheads and downgrade the performance of the VM. It may also cause slowing down of the VM machine which is being used by the systems.
• Another effective policy would be to allocate the resources effectively and making the performance appear in a baseline so that there are no fluctuations in the performance and the systems are maintaining consistency too.
• Using RAID 10 volumes is also an healthy practice as it enhances the techniques of storing the data in different hard drives with use of multiple disks which will help in avoiding the data redundancy.

Hence, these are the things that each of the virtual machines must have or else they will lack in or the other feature making the machine go under severe losses.
