Ephemeral Disk Support for Windows 1709 and Windows 1803 Stemcells

Hi all, We are rolling out Ephemeral Disk Support for the Windows Server, version 1709-based stemcells as well as Windows Server, version 1803-based stemcells! You can find them on https://bosh.io/stemcells/ What is this feature? This feature will allow you to have a much smaller root disk footprint, and allow you to use ephemeral disk for your applications! We have now reduced the root disk to be 30GB. What versions? You should find this feature in the 1709.13+ and 1803.2+ stemcells! Recommendations The minimum ephemeral disk size should be 30GB. You could configure your ephemeral disk based on your applications' needs. Our recommendation would be to have at least a 100GB ephemeral disk size. How to use it? You can utilize this feature just the way you've done with Linux previously with setting vm_types/vm_extensions in your cloud config. Once you've done that, you can then use that in your deployment manifest! Example - Cloud Config Example vm_extenions: - name: 100GB_ephemeral_disk cloud_properties: disk: 51200 Deployment Manifest Example instance_groups: - name: windows1709 instances: 1 vm_type: default stemcell: windows vm_extensions: [100GB_ephemeral_disk] The BOSH Windows team have worked hard to enable this functionality. Please do provide us feedback on it! Thanks, -- |
