Deploy Multinode DELLEMC ECS Elastic Storage S3 Community Edition in an AzureStack Availabilty Set

Prerequisites

The required VM Types need to have at least 4vCPU and 16GB memory. With the current AzureStrack VM Sizes, this would be 28G Memory per machine, so make sure you ASDK has enough Memory...

To depoloy to an ASDK Admin Tenant, just click on "ASDK Admin Tenant"
To depoloy to an ASDK User Tenant, just click on "Deploy to ASDK"

To deploy this template using the scripts from the root of this repo: (change the folder name below to match the folder name for this sample)
