Recently, I have been writing an IDC migration plan, sorting out the migration method of P2V as a record.

Statistics and calculation of existing capacity

Column 1 Column 2 Column 3 Column 4 Column 5 Column 6 Column 7 Column 8

Model CPU/ memory utilization CPU main frequency model logic total memory total hard disk capacity / number of remaining space hard drives operating system

IbmX336 15% 30 3.0GHZ 2 2 73g/30g 732 WINDONWS

IbmX336 5% 50% 3.0GHZ 2 73g/30g 732 WINDONWS

Calculation method:

Actual CPU resources = CPU frequency of this server X CPU quantity X CPU utilization

Actual memory resources = memory X memory utilization of this server

Actual hard disk space = hard disk capacity-remaining space

For example: for the first set: 3.0Ghz X 2 X 15% = 0.9Ghz, memory 2G X 30% = 0.6Gb, hard disk bit: 73gb-30gb=43GB

Draw the following table

Model CPU/ memory utilization CPU main frequency model requires cpu resources (Ghz) requires memory requires hard disk

IbmX336 15% 30% 3.0GHZ 0.9 0.6 43GB

IbmX336 5% 50% 3.0GHZ 0.3 1 65GB

After calculation, this project uses the cpu resources of 1.2Ghz. If the CPU of 91.194Ghz, taking the CPU frequency 3.0Ghz as an example, requires 30 cores (load 100%), but to consider that the load of CPU in the overall project is 60% and 75%, as well as the management overhead, at least 40 CPU cores are required to use this method to make hard drives.
