 Consider a scenario with multiple tasks requiring access to a common set of data, like rendering a movie. Each task renders one or more frames at a time from the scene files. By mounting a drive that contains the scene files, it's easier for compute nodes to access shared data.
 
-Additionally, the underlying file system can be chosen and scaled independently based on the performance and scale (throughput and IOPS) required by the number of compute nodes concurrently accessing the data. For example, you can use an [Avere vFXT](../avere-vfxt/avere-vfxt-overview.md) distributed in-memory cache to support large motion picture-scale renders with thousands of concurrent render nodes, accessing source data that is on-premises. Instead, for data that already is in cloud-based Blob storage, [blobfuse](../storage/blobs/storage-how-to-mount-container-linux.md) can be used to mount this data as a local file system. Blobfuse is only available on Linux nodes, though [Azure Files](../storage/files/storage-files-introduction.md) provides a similar workflow and is available on both Windows and Linux.

 ## Networking requirements
 
 When using virtual file mounts with [Azure Batch pools in a virtual network](batch-virtual-network.md), keep in mind the following requirements and ensure no required traffic is blocked.
