The most advanced and scalableenterprise SMB server on Linux

Fusion File Share by Tuxera is a high-performance, scalable, and highly reliable alternative to Samba and other SMB server implementations. It brings support for Microsoft’s Server Message Block (SMB) protocol to public cloud platform as a service (PaaS) offerings, software-defined storage (SDS) solutions, and enterprise-grade network attached storage (NAS). Our software makes it possible to securely share business-critical files over a network (SMB over QUIC) to many devices at the same time. Fusion has all the latest security and SMB capabilities to suit even the most demanding organizational needs.

When to use Fusion File Share by Tuxera SMB server

File storage and sharing challenges in public cloud

Serverless technologies, cloud file storage, and file-based applications from the cloud are some key pillars of today’s cloud-first strategies. As part of adopting these strategies, your PaaS and public cloud customers may need secure, shared file and data access. Server Messaging Block (SMB) technology is a key networking protocol needed in your architecture for providing file storage and access.

Unfortunately, some Linux-based SMB solutions are not able to stand up to the critical performance, high availability, and massive scalability demands you need to deliver your cloud service to your customers. Any downtime caused by poorly performing file sharing operations not only means lost time or money for your customers, but can also damage your reputation as a service provider. SMB solutions may also lack the most up-to-date security features and vulnerability fixes.

Fusion File Share for PaaS and Public cloud services

Our SMB implementation – Fusion File Share by Tuxera – works flawlessly with your cloud service to bring consistently high I/O throughput to file sharing applications. Fusion provides the reliability you need with availability features such as persistent handles and transparent failover. It also scales linearly to meet even the toughest throughput demands, adding more nodes to keep the pace.

Fusion File Share is easy to integrate into any PaaS or public cloud solution and is dynamically configured. Tuxera’s team of storage development experts support you all the way from evaluation to implementation, going above and beyond to ensure your project performs flawlessly and on schedule.

What’s more, Tuxera’s storage development team also monitors all the latest SMB vulnerabilities and security features. We ensure Fusion File Share has all the latest security updates, providing the rock-solid data security your customers are depending on. Our team has been credited by Microsoft for identifying and reporting critical SMB vulnerabilities – read more on our SMB security reporting here.

Challenges of implementing SMB in SDS architectures

Today’s data-driven enterprises are seeking software-defined storage (SDS) solutions to support traditional business operations in addition to supporting cloud services, big data and analytics, AI, ML, and other data-intensive workloads. SDS solutions must be flexible to meet a wide variety of customer needs, suitable for any hardware, and run on virtual, cloud, or container platforms. The make-or-break features for most SDS systems are focused on high performance: low latency, high input/output per second (IOPS), and low CPU overhead. Not to mention SDS solutions must be able to handle millions of files, scale to multiple petabytes of storage, and provide access to both structured and unstructured data.

SDS systems often use the SMB protocol for unstructured data and object access (directories and files). A variety of free and proprietary Linux-based SMB solutions are available for SDS providers to integrate as part of their solutions, but many are not able to meet the rigorous performance, availability, and massive scalability demands of your customers.

Fusion File Share by Tuxera for SDS systems

Fusion File Share by Tuxera, our SMB solution, reduces the bottlenecks and limits imposed by an under-performing SMB solution. It ensures consistently high performance, boosting I/O throughput while reducing CPU usage in scale-out distributed file system architectures. Our SMB server features a modular and threaded design, SMB over RDMA, and advanced SMB compression support to ensure the highest performance and rapid file transfers. In our tests working with parallel file systems, Fusion File Share was found to throttle throughput, contributing over 85% of the speed performance of the file system.

Our advanced SMB solution also enables fast, easy handling of multiple simultaneous connections to shared resources. It can be deployed in active-passive mode over the distributed file-system clients to provide high availability and transparent fail-over of connections. Fusion File Share also handles active-active clusters for scale out scenarios, and is deployable as a container.

Fusion File Share is easy to integrate into any SDS system and is dynamically configured. Tuxera’s team of storage development experts support you all the way from evaluation to implementation, going above and beyond to ensure your project performs flawlessly and on schedule.

Challenges with SMB file storage in media and broadcast

In today’s globalized media and content production houses, production files are shared over multiple geographic locations, with multiple users needing access to the same files, and multiple clients (PC workstations and Macs). High quality 8K+ resolution productions require hefty storage space – not to mention editing, rendering, and streaming these massive files over a shared network requires high-performance, low-latency software.

The SMB protocol is a critical technology used to facilitate file sharing and file applications over the distributed shared networks used in modern production houses and content streaming. Both free and proprietary Linux-based SMB solutions are available for use for media and content storage, but many are not able to meet the rigorous performance, availability, and massive scalability demands to satisfy your production or streaming needs. As a matter of fact, if your SMB server solution lacks advanced RMDA support, it’s not even possible to write files in 8K+ resolutions to a shared network.
