Cloud Cruiser became HPE Consumption Analytics on Nov. 1st. You'll still see the old name in places while we update this site.

VM sizing guidelines for CloudSmart-Now

To enable you to see how services for VMs of different sizes are being charged, CloudSmart-Now solutions organize VMs as either standard (matching commonly-used VM configurations) or non-standard (which do not match the exact configuration of the standard sizes). To make use of this functionality you must import the lookup tables needed for your data providers.

Lookup tables for public cloud providers

For public cloud providers (AWS and Microsoft Azure), HPE Consumption Analytics Portal uses lookup tables to set the initial VM configurations before using the VM sizing tables described in Lookup tables for all providers.

  • For AWS, HPE Consumption Analytics Portal uses the AWS_Size2VMInfo lookup table to set the initial VM configurations based on the VM type indicated in the collected data. For example, an m3.xlarge VM has 4 CPUs, 15 GB of memory, and 80 GB of disk space.
  • For Microsoft Azure, HPE Consumption Analytics Portal uses the Azure_VMType2VMInfo lookup table to set the initial VM configurations based on the VM type indicated in the collected data. For example, a Basic.A3 VM has 4 CPUs, 7 GB of memory, and 120 GB of disk space. Data in this table is based on sizing data provided by Microsoft at http://azure.microsoft.com/en-us/pricing/details/virtual-machines.

Lookup tables for all providers

HPE Consumption Analytics Portal uses the VM Sizes By Memory lookup table to determine initial VM sizes according to the memory allocated to the VM. The amount of memory is an upper range, so a VM with 6GB of memory is considered a Large VM.

VM size Maximum memory (in GB)
Micro 1
Small 2
Medium 4
Large 8
Extra Large More than 8

After determining the initial size of the VM, HPE Consumption Analytics Portal uses the Standard VM Size Definitions lookup table to determine whether the VM is standard or non-standard, using the combination of CPUs and memory as a guide:

VM size CPU_Memory combination
Micro 1_1
Small 1_2
Medium 2_4
Large 4_8
Extra Large 4_16

Any combination of CPUs and memory that differs from that VM's standard configuration is considered non-standard. For example, a VM with 8 GB of memory and 4 CPUs is a standard Large VM. A VM with 4 CPUs and 12GB of memory is a non-standard Extra Large VM. If you want to use different definitions for VM sizes, modify the memory and CPU values in the VM Sizes By Memory and Standard VM Size Definitions lookup tables.
