Smb 3.0 in windows server 2012

SMB version 3. 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. Using the SMB protocol, an application or the user of an application can access files or other resources at a remote server. This allows applications to read, create, and update files on the remote server.

For more information, see Windows Server software-defined datacenter. If you need to conserve storage space on an SMB file share, consider using Azure File Sync with cloud tiering enabled. 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.

For details, see Planning for an Azure File Sync deployment. Down-level clients can connect to file shares that have the CA property, but transparent failover will not be supported for these clients.

As the demand on the file server grows you can simply add another server into the cluster adding resource and bandwidth to your file server services. There are a few requirements to get this running, for example your file servers will need to use CSVs V2. Allows for very high throughput with ultra low latency by allowing the NICs themselves to do the work. I have looked at this in more detail here. SMB multi channel allows for multiple connections to be established for data transfer.

Traditionally if you wanted to transfer a 50GB file from one server to another using a server with 2x 1Gb network adaptors none teamed then a single SMB session would be established using one of the NICs and a single CPU core.

This would be slow and would more than likely max out the CPU core being used. You will have increased the possible bandwidth but you still only have one session going over the 2Gb pipe. That is where multi-session comes in. SMB multi channel is enabled by default there is no need to turn anything on in fact you have to explicitly turn it off which you can by via PowerShell:.

This gives the best experience as you will be able to take advantage of the the very high throughput and ultra low latency offered by RDMA NICs. SMB 3. All of this is available with hardly any overhead especially if you are using a compatible processor for example Intel i5 or i7 which allows the processor to offload the encrypt operation. Until SMB 3.

This is especially important for certain SMB Encryption deployment scenarios, as discussed in section 5 below. Dialect —lt 2. Since there are no other deployment requirements for SMB Encryption, it is an extremely cost-effective way to protect data from snooping and tampering attacks.

Administrators can very simply turn it on using either the File Server Manager, or using powershell, as shown below. Select the share you want to turn encryption on for, and right-click.
