SMB3: Overview
Posted by Anton Kolomyeytsev on May 10, 2016
4.6/5 (5)

This is an overview of the Server Message Block (SMB3) protocol from Microsoft. It offers a short insight into the history of SMB3 creation and development over the years (as the idea is technically around 30 years old). As of Windows Server 2012, the protocol got new features: SMB Transparent Failover, SMB Scale Out, SMB Multichannel, SMB Direct, SMB Encryption, VSS for SMB file shares, SMB Directory Leasing, SMB PowerShell. In Windows Server 2016, it also got Pre-authentication integrity and Cluster dialect fencing. The post concentrates on RDMA-capable SMB Direct and MPIO-utilizing SMB Multichannel and their benefits. Also, it is an introduction to a series of tests aimed at creating SMB 3.0 File Servers in an unusual way.

Hyper-V: Free “Shared Nothing” SMB3 Failover File Server
Posted by Anton Kolomyeytsev on January 22, 2016
5/5 (2)

A part of a series, the research is dedicated to the capability of free Microsoft Hyper-V Server R2 to assume a file server role and cluster the resulting file server. Our last experiment on this matter showed that it’s possible to create SMB3 File Server on the free Microsoft Hyper-V Server R2 and now we’re about to go further and cluster it. The post shows a detailed instruction on the process and also the resulting setup. It appears to be fully working and usable, so the process may be called a success after all. Though it is absolutely real to do so, it is a violation of Microsoft’s license agreement, so StarWind urges everyone to refrain from repeating the experiment.

Hyper-V: Free SMB3 File Server
Posted by Anton Kolomyeytsev on January 22, 2016
5/5 (1)

The first experiment dedicated to building a file server on free Microsoft Hyper-V Server R2. It is a part of a series of similar practical posts. The post offers a detailed instruction on how to assign file server role to the free Microsoft Hyper-V Server R2. However, this process is a violation of license agreement, so StarWind urges the readers not to repeat it. As to the reason the process is at all possible, the answer is quite simple: SMB3 is a crucial part of the free Microsoft Hyper-V Server R2 and the latter won’t work if the protocol support is cut out. In any case, a fact that you can do something doesn’t mean you should. Violating Microsoft’s user license agreement is some serious business you don’t want to get involved in.

Storage Replica: “Shared Nothing” SMB3 Failover File Server
Posted by Anton Kolomyeytsev on October 15, 2014
4.2/5 (5)

This is the first test in the series, dedicated to Microsoft Storage Replica – a new solution introduced in Windows Server 2016. It shows a step-by-step process of “Shared Nothing” Failover File Server building, based on the Server Message Block protocol (SMB3). Microsoft Storage Replica is a versatile data replication solution. It performs replication between servers, between volumes in a server, between clusters, etc. The typical use case for Microsoft Storage Replica is Disaster Recovery, which is basically replication to a remote site. It allows easy recovery of data in case the main site operation is disrupted by some sort of a force majeure, like natural disasters. The test is performed by StarWind engineers with a full report on the results.
