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). It makes it possible to securely share business-critical files over a network (SMB over QUIC) to many devices at the same time.

The solution powered by xiRAID & Fusion File Share by Tuxera satisfies the most demanding requirements of media and entertainment businesses: high performance of sequential and multi-thread workloads, providing integrity of media content, reliable and scalable storage of large volumes of data.

Test details

Test objective

Determine the maximum performance of sequential write and read operations over an SMB protocol on the xiRAID & Fusion File Share solution.


Test environment

Our test environment consists of one GIGABYTE R272-Z32 (rev. 100) AMD EPYC™ 7002 UP Server System with 10 nvme-drives and xiRAID and two windows-workstation clients. Server and clients connected to Nvidia Spectrum switch (Server connected to the switch with 100Gb Ethernet cables).

A diagram of the test site is shown below.

Tuxera - Test details


Storage configuration

xiRAID: RAID6 with 10 nvme WUS4BA138DSP3X1 (8 data + 2 parity)

Strip size=64K

Merge write and sched options are enabled: mw=300 (-mw --merge_wait), mm=1000 (-mm --merge_max), se=1

File system: EXT4

Test results

For this measurement we used industry-standard Frametest (Frametest 4.22) benchmarking tool to generate uncompressed 4K streams at 24 frames per second (FPS):

1, 2 and 4 stream, 4K-video and sequential read/write across the network using smb-shares on client

frametest.exe -w 4k -t <N> -n 9000 <dir>

frametest.exe -r 4k -t <T> -n 9000 <dir>

Superior performance makes the solution a perfect fit for media and entertainment workloads and highest-performing modular NAS on the market, despite the fact that, as a result of the tests, we were stymied by the bandwidth of the network and the capacity of our testing infrastructure.
