How is VM vRAM usage calculated in details?

Hi there

Can anyone help me with getting some information about how the "official" calculation is done inside vCloud Usage Meter?

I’m discussing how to have different report from VSPP partners.

When and how roundup /down are done. If they are used.

To illustrate it, here is an example:

6 VMs running 24/7 in a month with 30 days.

1x VM1 = 1024 mb vRAM (Totalt vRAM = 737280 mb vRAM)

5x VM2 = 768 mb vRAM  (Totalt vRAM = 2764800 mb vRAM)

When is it needed to calc it to GB? (Divide it with 1024)

Will a VM with 768 mb have a cost of less than 5/7/10 points?

Assuming vCloud Usage Meter take the total of all VMs, and calculates from that.

Using Monthly usage reports:

I take the totals amount of vRAM of all VMs

737280 + 2764800 = 3502080 mb vRAM

1290240 / 1024 = 3420 gb vRAM

1260 / 720 = 4,75 gb vRAM avg used

(In this example using 5 points) will this then be

5 x 4,75 gb vRAM         = 23,75 points

Or

5 x 5 gb vRAM = 25 points (Roundup at the GB level before calc points)

Or

5 x 5 gb vRAM = 25 points (Roundup / down at the GB level before calc points)

Or

5 x 4,75 gb vRAM         = 24 points (Roundup points from 23,75 points)

Or

5 x 4,75 gb vRAM         = 24 points (Roundup / down points from 23,75 points)

Here comes the tricky one:

Using Customer Summary Reports

Customer A are only using 3x VM2.

1658880 / 1024 = 1620 gb vRAM

1620 / 720 = 2,25 gb vRAM avg used

5 x 2,25 gb vRAM         = 11,25 points

Or

5 x 3 gb vRAM = 15 points (Roundup at the GB level before calc points)

Or

5 x 2 gb vRAM = 10 points (Roundup / down at the GB level before calc points)

Or

5 x 2,25 gb vRAM         = 12 points (Always roundup points)

Or

5 x 2,25 gb vRAM         = 11 points (Roundup / down points)

Customer B are only using 1x VM1 and 2x VM2.

1843200 / 1024 = 1800 gb vRAM

1800 / 720 = 2,5 gb vRAM avg used

5 x 2,5 gb vRAM           = 12,5 points

Or

5 x 3 gb vRAM = 15 points (Roundup at the GB level before calc points)

Or

5 x 3 gb vRAM = 15 points (Roundup / down at the GB level before calc points)

Or

5 x 2,25 gb vRAM         = 13 points (Rounded up points)

Or

5 x 2,25 gb vRAM         = 13 points (Roundup / down points)

Total points using Customer reporting vs Usage Report: (depending on calc method)

• Customer Reporting      Usage Report
• 23,75 points                    23,75    points Using decimals
• 30 points                         25 points Roundup at the GB level before calc points
• 25 points                        25 points Roundup / down at the GB level before calc points
• 25 points                        24 points Rounded up points
• 24 points                        24 points Roundup / down points

And this assumes it is calculated from total vRAM.

If its calculated pr VM > points, then its even more complicated.
