![]() If we combine that with the easy of management that Nerdio Manager for WVD offers with regards to setting up and managing your Workspaces/Tenants, (Dynamic) Host Pools together with our sublime autoscaling technology and image management capabilities, you have a true winner on your hands.Įven though machines with Ephemeral disks cannot be stopped/deallocated, the way the Nerdio autoscaling technology adds and removes VM’s while retaining all important information like the machine name, IP address, DNS and Active Directory records and so on, makes it the perfect mechanism to take care of this. If you use Windows Virtual Desktop for pooled session desktops (Server OS/Windows 10 Multi-Session), pooled single user desktops (Desktop OS), or RemoteApps (published applications), and of course most do, Ephemeral disks are a great fit. Oh, and before I forget, Ephemeral disks are supported in all regions world-wide. Go here for pointers on how to handle Ephemeral management through PowerShell, the CLI, ARM templates, REST, and the Azure portal. ![]() when you are able to manage them properly, that is. ![]() If you have a solid profile management solution, like FSLogix in place together with one or multiple golden images, Ephemeral disks make a welcome addition to the Windows Virtual Desktop family taking care of the various stateless workloads use-cases you have. In other words, the cache size of the VM you select determines the maximum size of the Ephemeral disk. Note that only Managed disks are supported. Supported VM types: DSv1, DSv2, DSv3, Esv3, Fs, FsV2, GS, ad M. The disk size can only be changed during the VM creation, not afterwards. Have a look here to get an idea of the various cache sizes per VM If the cache size of the selected VM type is not large enough to hold your base (golden) image (in GB’s) you need to select another VM (type) with a larger cache size. Read on to find out why this isn’t stopping Nerdio Manager for WVD from taking full advantage.Įphemeral disks are created a part of the VM cache, depending on the type of VM you select (not all types are supported, more on this below) the size will vary – with a maximum of 2 TB. If you have any other disk types attached to the VM, you will pay for those as well.Īnother important thing to note is that Ephemeral disks cannot be stopped/deallocated. Though, keep in mind that the Azure compute used as part of the VM that the Ephemeral disk is part of will still cost you money – nothing new there. To start with a big pro, they are free! You are not charged for storage costs. As always, there are multiple pros and cons to consider. This makes them ideal for stateless workloads, providing lower latency and thus faster read and write times. They are created on the virtual machine’s local storage (as part of the available VM cache, read on below) and are not written/saved to Azure Blob storage. ![]() Ephemeral OS disks are a form stateless disk storage. ![]()
