[vivekds]

Hi,

What is mean by % reserve RAM? It is what we set reservation min, max in VM properties---Resource tab?

It refers to the reservation set for each VM in %.  The reservation not the limit.

How To Manage Customer Information

In order to prevent an excessive amount of manual data entry, the vCloud Usage Meter enables users to import and export customer lists. Users can also create, read, update, and delete customers and customer relationships to virtual machines with the vCloud Usage Meter.

Note: The following italicized sections are applicable only for users of older editions of Usage Meter. Stating with v3.2, Usage Meter calculates this data for Service Providers, so the manual steps described in Italics are not needed

How Points Are Calculated on Usage Data (Applicable only when using Usage Meter version older than 3.2)

The VMware vCloud Service Provider Bundles are charged as per aggregated reserved RAM usage, and charging is done through a monthly point system where months can have the following number of days:

• 28-day months = 672 hours
• 29-day months = 696 hours
• 30-day months = 720 hours
• 31-day months = 744 hours

The formula for calculating net points is:

Net points = (vGB hours X points per 1 GB reserved RAM) / hours per month

vGB = Virtual Gigabyte

How the Formula Works

Points per 1 GB reserved RAM

• 5 points per 1 GB Reserved RAM for VMware vCloud Service Provider Bundle – Standard Edition
• 7 points per 1 GB Reserved RAM for VMware vCloud Service Provider Bundle – Premier Edition
• 10 points per 1 GB Reserved RAM for VMware vCloud Service Provider Bundle – Premier Plus Edition

vGB hours are calculated with consideration of floor (minimum value) and ceiling (maximum value) values

• The floor value is equal to a minimum of 50 percent vRAM reservation. For example, if you set vRAM reservation below the floor value, to 35%, your usage will be metered at the minimum, viz. 50%.
• The ceiling value or a 24 GB cap is the maximum value that could be charged. For example, if you are consuming 1 terabyte of vGB hours, then you will only be billed for 24 GB of vGB hours.

Example

During one 30-day calendar month, a Service Provider uses the vCloud Service Provider Bundle – Premier Edition to configure her virtual machine with 16 vGB for 15 days and 48 vGB for the remaining 15 days. The reservation level for the virtual machine is set at 75 percent for the entire month.

• 15 days x 24 hours x 16 vGB x 0.75 = 4,320 vGB hours
• 15 days x 24 hours x 24 vGB (48 vGB x 0.75 but capped at 24 GB) = 8,640 vGB hours
• Total vGB hours = 12,960 vGB hours
• Total points = 12,960 vGB hours ÷ 720 hours/month x 7 points (for Premier) = 126 points

Thanks for reply. But where to set this reservation?

[tedg_vCrumbs · Accepted solution]

The reservation is set on the VM itself.

Resource Tab.

--See Screen Shot

----My screen shot shows a VM with a 90% reservation.

No reservation results in 50% of your vRam allocation being charged.  If you set a reservation below 50% you will be charged 50%.
