Other important attributes to pay attention to are VMDK size and #VMDKs - so in the example above the total VM size is 60gbx2 = 120gb - which mean we need a total of 120gbx100 = 12TB usable capacity. How would I go about finding the slackspace of a file, for instance. And in particular, you are dealing with the forces produced when the line is tensioned. Be careful that the value of slack variable can be in fraction as well, for example, let's say C=0.6, then it might the possible that we have three points with slack variable = 0.2 or two points with slack variable = 0.3; or we have C=1.6 with one slack variable =0.6 (wrong side of margin) and another slack variable= 1 (wrong side of the plane). Microsoft Windows based systems normally write in 512 byte blocks called Sectors. RAM Slack Lets add a little twist to the whole thing!
