In today’s heterogeneous environment of data centers, where both Windows and non-Windows platforms are concurrently used, the SMB implementation (formerly known as CIFS) becomes essential for data centers in a non-Windows environment. Since the SMB protocol is only native to the Windows world, Visuality Systems developed and released a portable SMB Server that can be integrated into any storage solution. NQ™ Storage inherited its technology from the embedded SMB solution, NQE™, which runs in millions of scanners, printers, home routers and other devices.
NQ™ Storage is a commercial, high performance SMB stack that offers flexible integration for a wide range of storage services, from standalone NAS to high-end data centers.

NQ Storage architecture for a standalone server:
NQ Storage architecture for a clustering storage system:
Through the implementation of the latest SMB dialects, NQ™ Storage is the ultimate SMB storage solution in the market today. In contrast to the open source Samba, NQ™ Storage is not process based but thread based, which allows the capability of handling heavy loads in terms of thousands of client connections, numerous open files, etc., while having a very low resource consumption.
NQ™ Storage uses thread pools, internal memory management (pre-allocated buffers), zero copy for payloads of read and write operations, and server side operations such as file copying, zeroing and remapping to minimize network traffic. This makes it ideal for boosting performance when used with advanced applications such as Hyper-V and SQL Server.
NQ™ Storage fully complies with Microsoft SMB2 and SMB3 specifications. This includes such essential features as Domain Authentication (aka Active Directory) and others. The compliance is guaranteed by testing with the Microsoft Protocol Test Suite. NQ™ Storage supports all SMB dialects up to 3.1.1. This grants connectivity from all latest client versions of Microsoft, Apple Macintosh and Samba.
