Quest has published a template virtual machine (VM) in the Azure Marketplace for Rapid Recovery. This VM template allows you to deploy a Core server to Azure where you can choose the size of VM you want to run. To better understand Azure VM sizing and performance, the Rapid Recovery team has done some basic performance testing of three different VM configurations. The results are published here to help in establishing some baseline expectations for jobs run by Rapid Recovery cores running within Azure.
Here are the 3 VM configurations tested:
The below chart contains the duration in seconds of several tested jobs. The results have been color coded red, yellow, and green going from slowest to fastest respectively.
As you can see the performance improves greatly as you increase the VM size. The first two VMs (DS3_v2) are identical from a compute standpoint containing the same 4 CPU and 14 GB of RAM with the only difference being the size of the repository disk. The first one has a single 4 TB disk and the second has a single 32 TB disk. In all tests, the 32 TB disk performed better even though the compute size of the VM is identical.
The third VM (F8s) tested is a substantially more performant VM with 8 CPU and 16 GB RAM but the same single 32 TB disk configuration. In all but one test, this VM performed jobs faster than the other two VMs. Even though most of these jobs are extremely reliant on the speed of the disk, the size of the VM also appears to have an effect on the performance of jobs.
