Summary:
The documentation provides detailed instructions and examples for Azure CLI and Azure PowerShell, with the PowerShell section being particularly extensive. PowerShell is a Windows-centric tool, and its prominence, along with the absence of explicit Linux shell (bash) examples or references to Linux-specific tooling, indicates a Windows bias. There are no Linux-specific command-line examples, nor is there guidance for Linux users beyond the Azure CLI, which is cross-platform but not presented with Linux-specific context or examples.
Recommendations:
- Add explicit bash/Linux shell examples for creating and managing Azure HPC Cache resources, demonstrating parity with PowerShell examples.
- Clarify that Azure CLI commands can be run on Linux, macOS, and Windows, and provide Linux-specific setup instructions (e.g., package manager installation commands).
- Include references to Linux-native tools or workflows where appropriate, such as using bash scripts or integrating with Linux authentication/identity mechanisms.
- Balance the prominence of PowerShell by ensuring that Linux and cross-platform workflows are equally represented and easy to follow.
- Where PowerShell is mentioned, also mention bash or shell scripting alternatives for Linux users.

## Create the cache with Azure PowerShell
> [!NOTE]
> Azure PowerShell currently does not support creating a cache with customer-managed encryption
> keys. Use the Azure portal.
Use the [New-AzHpcCache](/powershell/module/az.hpccache/new-azhpccache) cmdlet to create a new Azure
HPC Cache.
Provide these values:
* Cache resource group name
* Cache name
* Azure region
* Cache subnet, in this format:
`-SubnetUri "/subscriptions/<subscription_id>/resourceGroups/<cache_resource_group>/providers/Microsoft.Network/virtualNetworks/<virtual_network_name>/subnets/<cache_subnet_name>"`
The cache subnet needs at least 64 IP addresses (/24), and it can't house any other resources.
* Cache capacity. Two values set the maximum throughput of your Azure HPC Cache:
* The cache size (in GB)
* The SKU of the virtual machines used in the cache infrastructure
[Get-AzHpcCacheSku](/powershell/module/az.hpccache/get-azhpccachesku) shows the available SKUs and
the valid cache size options for each one. Cache size options range from 3 TB to 48 TB, but only
some values are supported.
This chart shows which cache size and SKU combinations are valid at the time this document is
being prepared (July 2020).
| Cache size | Standard_2G | Standard_4G | Standard_8G |
|------------|-------------|-------------|-------------|
| 3072 GB | yes | no | no |
| 6144 GB | yes | yes | no |
| 12,288 GB | yes | yes | yes |
| 24,576 GB | no | yes | yes |
| 49,152 GB | no | no | yes |
Read the **Set cache capacity** section in the portal instructions tab for important information
about pricing, throughput, and how to size your cache appropriately for your workflow.
