Windows 10 samba server9/27/2023 ![]() Features added in Windows Server 2019 and Windows 10, version 1809 Feature/functionalityĪbility to require write-through to disk on file shares that aren't continuously available ![]() The following sections describe functionality that was added in SMB 3 and subsequent updates. For details, see Planning for an Azure File Sync deployment. This allows you to cache your most frequently accessed files locally and tier your least frequently accessed files to the cloud, saving local storage space while maintaining performance. If you need to conserve storage space on an SMB file share, consider using Azure File Sync with cloud tiering enabled. These enhancements include reducing the application latencies experienced by branch office users when accessing data over wide area networks (WAN) and protecting data from eavesdropping attacks. The SMB 3.0 protocol provides enhancements to the Information Worker (or client) workloads. Traditional storage for end-user data.Upcoming versions of SQL Server will add support for clustered SQL servers and system databases. Currently, this is supported with SQL Server 2008 R2 for stand-alone SQL servers. SQL Server can store user database files on SMB file shares. ![]() This can be used for both stand-alone file servers and clustered file servers that use Hyper-V together with shared file storage for the cluster. Hyper-V can store virtual machine files, such as configuration, Virtual hard disk (VHD) files, and snapshots, in file shares over the SMB 3.0 protocol. File storage for virtualization (Hyper-V™ over SMB).This section discusses some new practical ways to use the new SMB 3.0 protocol. For more information, see Windows Server software-defined datacenter. SMB is a fabric protocol that is used by Software-defined Data Center (SDDC) computing technologies, such as Storage Spaces Direct, Storage Replica. SMB can also communicate with any server program that is set up to receive an SMB client request. This allows applications to read, create, and update files on the remote server. Using the SMB protocol, an application (or the user of an application) can access files or other resources at a remote server. The SMB protocol can be used on top of its TCP/IP protocol or other network protocols. The Server Message Block (SMB) protocol is a network file sharing protocol that allows applications on a computer to read and write to files and to request services from server programs in a computer network. SMB version 3.0 was introduced with Windows Server 2012 and has been incrementally improved in subsequent releases. ![]() SMB is also a fabric protocol used by software-defined data center (SDDC) solutions such as Storage Spaces Direct, Storage Replica, and others. This topic describes the SMB 3 feature in Windows Server 2019, Windows Server 2016, Windows Server 2012 R2, and Windows Server 2012-practical uses for the feature, the most significant new or updated functionality in this version compared to previous versions, and the hardware requirements. If your version of Samba does not support these configuration options, it is a really old version that should be updated as soon as practical.Applies to: Windows Server 2022, Windows Server 2019, Windows Server 2016, Windows Server 2012 R2, Windows Server 2012 If you have an old version of Samba that defaults to using SMBv1 only, you can probably add a server max protocol = SMB2 or server max protocol = SMB3 to explicitly enable the newer protocol versions. With up-to-date versions of Samba, fixing this typically requires only removing any explicit server max protocol restrictions from the configuration. If the response is anything that doesn't begin with either SMB2 or SMB3, your Samba configuration is currently restricted to SMBv1 only. Run testparm -s -parameter-name "server max protocol" /etc/samba/smb.conf 2>/dev/null. You should verify that your Samba configuration does not have a server max protocol = setting (either as explicit configuration or as an implicit default setting) that will restrict Samba from using SMBv2 or SMBv3. Since SMBv1 has a critical design flaw that enabled the spread of the original WannaCry ransomware worm, this is a good thing. Windows 10 is deprecating SMB protocol version 1, not installing server components for it by default anymore, and automatically disabling the client components for it if it does not seem to be needed.
