Importing workload requirements is useful for any existing workload. Although every sizer option provides an accurate estimate when the correct information is provided, data import ensures accurate data. Data-driven sizing is still dependent on when the data is captured. You can miss important requirements if the workload requirements are captured during a low activity period.
Prerequisites
To import sizer requirements, ensure that you have existing RV tools or Live optics data for the tool to upload.
Procedure
- Open https://vmc.vmware.com/sizer/home on a new browser.
- On the VMware Cloud sizer home page, under the Advanced Sizer, click Import under Import on-premises data. You can choose RV Tools(.xlsx), Live Optics(.xlsx), or Aria Operations(.JSON) to import the file.
- Select the import file, and click CHOOSE FILE to import. For information on mapping the collector fields against the Sizer, see VMware Cloud Sizer to Collector Field Mapping Guide
- Select the required additional preferences as required and click Upload.
Note:
- RVTools - RVTools is a free Windows .Net application that connects directly to any existing vSphere environment and exports a current snapshot of the inventory. This snapshot does not include storage performance requirements. It uses the vCenter API to generate an excel sheet file that contains the details on every VM in the environment. By uploading the file, you can get more accurate sizing because the sizer contains details of every VM configurations.
- Live Optics - Live Optics is a free service from Dell EMC that can capture workload utilization over a designated period. The tool enables non-invasive agent-driven data collection of any workload and can run for a given duration. Live optics is preferred as it includes storage performance data and can be particularly helpful when dealing with high workloads. It is similar to RV Tools but slightly better as you can accurately account for performance and capacity.
