1. Summary
File storage remains one of the most popular ways to store data, both on premises and in the cloud. Scale-out file storage is becoming the default choice for most organizations because it can be quickly expanded to increase throughput. There are other reasons for the success of scale-out file storage:
- Object storage, although very popular, isn’t overshadowing file systems yet. File systems, often accessed via network protocols like NFS and SMB, are the data storage system of choice for a large number of workloads, including big data analytics, artificial intelligence/machine learning (AI/ML), high-performance computing (HPC), and more.
- Modern file systems are much more scalable than in the past, and they provide a familiar user interface and authentication methods along with excellent performance.
- Legacy applications continue to drive the demand for file storage. Such applications were usually written to work with POSIX-compliant file systems, and the cost of refactoring them to benefit from object storage likely outweighs the benefit, thus making file storage a preferred option.
- Modern scale-out solutions are mature and flexible, with most of the complexity now hidden behind the scenes. In the end, managing a single large scale-out system is less time consuming than managing several scale-up systems.
- Solutions that support data mobility across different environments are becoming increasingly important for executing properly on hybrid IT strategies, and scale-out file storage systems are easy to implement on cloud virtual machine instances. In fact, GigaOm recently published a report about cloud-based file storage, because there is a growing demand for sophisticated file services on-premises and in the cloud.
With unstructured data accounting for up to 90% of what is stored in enterprise infrastructures, storage that is scalable and fast enough to manage interactive workloads is crucial for responding adequately to business needs. That said, enterprises don’t want to get that scalability and performance at the expense of the data services and flexibility they usually get from traditional scale-up network attached storage (NAS) solutions. This is why scale-out storage systems are much more balanced than in the past and try to meet enterprise requirements like scalability, flexibility, efficiency, and performance.
