@Charlie Newey Welcome to Microsoft Q&A Forum, Thank you for posting your query here!
Azure HPC Cache will be retired on 30 September 2025. You can still create HPC Caches through September 2025. Please see a list of frequently asked questions (FAQs) here.
Visit https://aka.ms/hpccacheretirement for more information about the retirement.
At this point, we do not have an exact alternative. However, we will provide an update very soon. The choice of alternative depends on your workload. You can consider using Azure NetApp Files based on your workload.
Azure NetApp Files is a fully managed file service that is built on NetApp's ONTAP technology, and provides high-performance file storage for enterprise workloads.
Azure NetApp Files is designed to provide a high-performance, scalable, and reliable file storage solution for a wide range of workloads, including HPC workloads. It provides features such as high throughput, low latency, and high availability, and can be used to store and manage large amounts of data.
Azure NetApp Files supports a wide range of protocols, including NFS, SMB, and iSCSI, and can be integrated with a variety of tools and services, such as Azure Backup, Azure Site Recovery, and Azure Monitor.
Note: That's only valid for specific workloads and customer requirements. For example, what if you have an all Isilon shop? What if you are using HPC Cache for a few hours? What if they are a small shop and not enterprise? What if they are cost-conscious and don't have the budget? In those cases, ANF is NOT a recommendation.
Please let us know if you have any further queries. I’m happy to assist you further and work closer on this issue.
