Operating SystemsI/O Performance AnalysisPart 1Start your Linux Partition from a fresh boot and open the Terminal. Do not open any other applications at this time.NOTE: You may need to install the “sysstat” and “iotop” package for this exercise:Type command:apt-get install sysstatapt-get install iotoprun the following command to create a 50MB test filedd if=/dev/zero of=test.file bs=1024 count=50000Now run this command to repeatedly create another file from the first file. This is creating I/O load on the system.while true; do dd if=/test.file of=test2.file bs=1024;rm test2.file; doneUsing iostat watch the I/O for your devices and all of its partitions over 30 second intervals. List the command used and record your findings. Do not display CPU statistics.Using iotop, report which three processes are the most I/O intensive.Part 2Add 3 new 50 MB Fixed Size Virtual Disks to your linux Partition. This is done using the Virtual Box interface while your Linux Virtual Machine is shut down.Switch to the root usersudo su -Using fdisk create 3 new “linux raid auto” partitions. One for each new drive added. Use the full space available on each disk.i.e. /dev/sdb1 /dev/sdc1 /dev/sdd1install “mdadm” packageapt-get install mdadm*If asked for a “mail server” choose “No Configuration”**This can take a few minutes to install.Create a striped array (RAID 0) using all three disks.Create Filesystem on New Raid 0 ArrayMount your new striped filesystemWhat is the size of the filesystem? Why?Repeat Part 1 of this assignment but this time make sure you are using your new striped filesystem. To do that just change to that directorycd /stripefsSummarize your findings about your new RAID 0 filesystem and iostat output.Did you achieve desired results? If not, why not and what would need to be changed in a real world production server to achieve desired results?Submission RequirementsYou will submit a Word or Libre Writer Document which contains results from the above analysis and responses. I do not have access to your system so you need to be sure to provide screenshots for anything I cannot possibly know.I don’t need screenshots for every piece of output you analyze during this assignment. Just give screenshots which show snapshot information to support your overall findings.Please insert your screenshots into your word document with supporting documentation which meets all requirements. You will be penalized for any results which are not backed by proof.

This is a program editing job. I need a tutor who is proficient in C++ to help me complete this task. In the process of completing the assignment, I hope you can give enough comments to each method to help me understand what you are doing at each step. The specific job content is in the following file. Looking forward to working with you.
