How can NAKIVO Backup & Replication protect your infrastructure? – NAKIVO Backup & Replication is a powerful yet affordable tool which offers multiple data protection options, including backup, backup copy, backup to cloud, replication, and site recovery.

New Hyper-V Features You Should Know About

Windows Server 2019 adopted the most effective features of its predecessor, Windows Server 2016, and greatly improved them to achieve even better results. Windows Server 2019 also presented a rich set of Hyper-V features which provide extended support for hybrid cloud deployments, hyper-converged infrastructure, and network security.

In today’s blog post, we are going to discuss how Windows Server 2019 has transformed Hyper-V functionality and what new Hyper-V features can do.

True two-node clusters

Previously, the File Share Witness could only exist on a physical file server or in the Azure Cloud. In Windows Server 2019, you can create two-node clusters, including Hyper-V clusters, using a USB flash drive as a file share witness. For example, if you have a four-node cluster, with two nodes at each site, and one node accidentally fails, a File Share witness can provide an additional vote in order to reach a quorum in a cluster. The upside of this approach is that the USB witness can function even without Internet connectivity or shared drives. Thus, true two-node technology can significantly simplify the process of determining quorum for a cluster.

Storage Spaces Direct improvements

Windows Server 2019 has greatly improved storage performance with the help of new functionality, which includes native support for persistent memory, nested resiliency for two-node infrastructures, and mirror-accelerated parity, among other features.

In Windows Server 2019, storage configuration maximums have also been improved.

Windows Server 2016 Windows Server 2019
Scale up to 1 petabyte (PB) of raw capacity per cluster Scale up to 4 petabytes (PB) of raw capacity per cluster
Create 32 volumes Create 64 volumes
Support volume sizes up to 32 TB Support volume sizes up to 64 TB

As a result, enhanced configuration maximums allow for increasing Hyper-V storage capacity and achieving better I/O performance.

ReFS deduplication

Another feature of Windows Server 2019 is ReFS deduplication, which allows you to enjoy the benefits of both data deduplication and the ReFS file system. By removing duplicated data blocks, you can ensure that only unique data is saved and storage space consumption is reduced.

Windows Admin Center

Windows Admin Center is a server management solution which allows you to easily manage your servers as well as hyper-converged infrastructure from a single pane of glass. Managing local and remote servers is simplified due to the use of familiar tools (PowerShell, Task Manager, Remote Desktop, etc.).

Windows Admin Center Interface (Hyper-V Features)

Previously, certain Hyper-V features could only be configured using PowerShell cmdlets. Windows Admin Center can now provide access to these features using simple and intuitive GUI. Moreover, Windows Admin Center can integrate with Azure services, thus allowing you to enjoy the benefits of hybrid cloud environments.

Shielded Virtual Machines

Shielded virtual machines (VMs) were introduced in Windows Server 2016. The main purpose of this security feature is to ensure protection of Generation 2 Hyper-V VMs against unauthorized access. In Windows Server 2019, this Hyper-V feature can do even more.

First of all, Windows Server 2019 can provide shielded VM protection for Linux VMs. Moreover, you can troubleshoot your shielded VMs, for example, to restore failed network connectivity to your VM. Last but not least, you can start up and run shielded VMs remotely (for example, in branch offices with poor Internet connectivity). For this purpose, you need to enable the Host Guardian Service (HGS) in the branch office and configure fallback URLs which allows for falling back to the main datacenter in case the primary HGS server cannot be reached.

Container advancements

Windows Server 2019 supports both Windows and Linux containers, which can run on the same container host. Moreover, Windows Server 2019 includes built-in Kubernetes support, which can significantly improve container networking. Additional container improvements include integrated Windows authentication in containers, improved application compatibility, and reduced size of base container images. These Hyper-V features can increase the speed of container workflows, make containers more secure and reliable, and ensure the efficiency of container networking.

Encrypted networks

Virtual network encryption is another Hyper-V feature available in Windows Server 2019, which enables encryption of virtual network traffic between VMs. Each packet leaving a selected VM will be automatically encrypted when moving across network subnets. Along with Datagram Transport Layer Security, encrypted networks can help you protect your infrastructure against data tampering, network eavesdropping, or theft.

Data Protection with NAKIVO Backup & Replication

NAKIVO Backup & Replication is a reliable and cost-effective data protection solution which can help you protect Hyper-V, VMware, Nutanix, and AWS EC2 environments while saving you time, effort, and money. Let’s see how NAKIVO Backup & Replication can ensure protection of your Hyper-V environment:

  • Create image-based, agentless, incremental and application-aware backups of running Hyper-V VMs.
  • Save up to 1,000 recovery points for each Hyper-V backup, which can be rotated on a daily, weekly, monthly, and yearly basis.
  • Automatically exclude unnecessary swap files, deduplicate backed-up data, and compress all data blocks, which can improve storage capacity and reduce storage space requirements.
  • Create copies of your Hyper-V VM backups and store these copies offsite or in the cloud (Azure or AWS).
  • Create and maintain exact copies of source Hyper-V VMs on a target host using Hyper-V Replication. You can then fail over to these VM replicas and continue business operations without experiencing significant service disruption or business downtime.
  • Automate and orchestrate the entire disaster recovery process through creating Site Recovery (SR) workflows. You can create multiple SR jobs, with each being tailored to address a specific DR scenario.
  • Run non-disruptive recovery testing of your SR jobs to ensure that your DR plan is effective, and that your recovery objectives can be met.
  • View all past, current, and future data protection jobs using NAKIVO’s simple web interface; you can easily schedule them from any device and at any time.
  • Simplify data protection management by setting up policies that can regularly scan your virtual infrastructure and automatically protect the VMs which match these policy rules.
