Microsoft released a new build Windows Server vNext (LTSC).
This release contains both the Desktop Experience and Server Core installation options for Datacenter and Standard editions. So everything you need is to be found in this new release.
Microsoft provided some Keys to install and test this new build seen below in the description. The previews expire on January 31, 2021.
New in this release:
File Services: SMB improvements
We’ve expanded the SMB 3.1.1 protocol in Windows Server vNext with a number of security and performance capabilities, including:
- AES-256 – Windows Server now supports AES-256-GCM and AES-256-CCM cryptographic suites for SMB Encryption. Windows will automatically negotiate this more advanced cipher method when connecting to another computer that supports it, and can also be mandated through Group Policy. Windows Server still supports AES-128 for down-level compatibility.
- Compression – You can now copy files over SMB with compression using the Robocopy /compress and Xcopy /compress If the destination computer supports SMB compression and the files being copied are compressible, you should see significant performance improvements. For more information and a demo of this behavior, visit the ITOps Talk Blog. Any patched Windows Server 2019 and Windows 10 computers already support compression; now you will have command-line tools to make use of it.
- RDMA encryption – SMB Direct over RMDA networks now supports encryption. Previously, enabling SMB Encryption would disable direct data placement, making RDMA performance as slow as TCP. Now data is encrypted before placement, leading to relatively minor performance degradation while adding AES-256 protected packet privacy.
- East-West storage encryption – Windows Server failover clusters now support granular control of encrypting and signing intra-node storage communications for Cluster Shared Volumes (CSV) and the storage bus layer (SBL). This means that when using Storage Spaces Direct, you can decide to encrypt or sign east-west communications within the cluster itself for higher security.
Storage Migration Services improvements:
Today marks our introduction of third generation of Storage Migration Service improvements, including:
- AFS Tiering support preview – SMS now supports migrating data to a server configured with Azure File Sync cloud tiering, which allows you to overprovision storage while dehydrating data to Azure Files in the cloud. SMS now understands this scenario and can slow or pause transfers to allow AFS to catch up in it tiering to the cloud. This feature also makes changes to the SMS extension in Windows Admin Center, which will release separately to the feed at a later date. Please follow the Microsoft FileCab blog for updates.
- Scenarios backported to Windows Server 2019 are included – Cluster, Samba-Linux migration support, Local security principal migration, and Inter-network migration were all added as backported features to Windows Server 2019 since its release. If you had not patched, you would not have access to them. They are now included out-of-the-box in Windows Server vNext.
We have also recently completed two new customer-requested Storage Migration Service scenarios and will be releasing them to Insiders in the coming months. Check the release notes and the Microsoft FileCab blog for updates.
