 When using ephemeral OS, the OS disk must fit in the VM cache. The sizes for VM cache are available in the [Azure documentation](../virtual-machines/dv3-dsv3-series.md) in parentheses next to IO throughput ("cache size in GiB").
 
-Using the AKS default VM size Standard_DS2_v2 with the default OS disk size of 100GB as an example, this VM size supports ephemeral OS but only has 86GB of cache size. This configuration would default to managed disks if the user does not specify explicitly. If a user explicitly requested ephemeral OS, they would receive a validation error.

+The latest generation of VM series does not have a dedicated cache, but only temporary storage. Let's assume to use the [Standard_E2bds_v5](/azure/virtual-machines/ebdsv5-ebsv5-series#ebdsv5-series) VM size with the default OS disk size of 100 GiB as an example. This VM size supports ephemeral OS disks but only has 75 GiB of temporary storage. This configuration would default to managed OS disks if the user does not specify explicitly. If a user explicitly requested ephemeral OS disks, they would receive a validation error.

 Ephemeral OS requires at least version 2.15.0 of the Azure CLI.
