Hyper-V

Hyper-V is a native hypervisor; it can create virtual machines on x86-64 systems and supersedes Windows Virtual PC as the hardware virtualization component of the client editions of Windows NT. A server computer running Hyper-V can be configured to expose individual virtual machines to one or more networks. Hyper-V Server supports remote access via Remote Desktop Connection. Administration and configuration of the host OS and the guest virtual machines is generally done over the network.

What are some good heuristics when considering the ratio of total Guest vCPUs to Host Physical Cores(ignoring HT/SMT); 2:1, 3:1?
The more involved followup might be how to measure core contention on a Hyper-V Host

Also when does core count matter more vs frequency, I guess the answer is workload dependent.
20 Cores @ 2.5Ghz (50k Ghz)
16 Cores @ 3.7Ghz (59.2k Ghz)

Microsoft used to have a set of values for VM counts depending on processor core count and GHz. Those recommendations have essentially been sidelined due to the fact that CPU is pretty much not the bottleneck anymore.

That being said, we go for GHz before core count as a rule because it's just that much faster to get the smaller vCPU count VM's threads through the CPU pipeline.

And finally, a wide core count would indeed be needed for multi-threaded applications like SQL to get through the pipeline as soon and as wide as possible.

In previous parts of this Nano Server deployment series, we learned how to create, deploy and configure Nano Server as a Hyper-V host. In this part, we will look for a clustering option. We will create a Hyper-V cluster of 3 Nano Server host nodes with Storage Spaces Direct on it.

Ransomware is a malware that is again in the list of security concerns. Not only for companies, but also for Government security and even at personal use. IT departments should be aware and have the right knowledge to how to fight it.

Lab Topology
In this article, I am going to show you how to simulate a multi-site Lab environment on a single Hyper-V host. I use this method successfully in my own lab to simulate three fully routed global AD Sites on a Windows 10 Hyper-V host.

10 Tips to Protect Your Business from Ransomware

Did you know that ransomware is the most widespread, destructive malware in the world today? It accounts for 39% of all security breaches, with ransomware gangsters projected to make $11.5B in profits from online extortion by 2019.

Exchange server is not supported in any cloud-hosted platform (other than Azure with Azure Premium Storage).

Why should I virtualize? It’s a question that’s asked often enough. My response is usually “Why SHOULDN’T you virtualize?”

First I will try to share a design of a Veeam Backup Infrastructure without Direct NFS Access backup.

Veeam-Backup-no-NFS.jpg
Note: Direct NFS Access backup transport mechanism is only available in Veeam v9

In above I try to design the Veeam Backup flow between iSCSI vs NFS.

In this case we did not had the proper configuration so that Direct NFS Access backup transport mechanism could work.

In this case we have a Veeam Backup Server and a Veeam Backup proxy.

Actual Veeam Backup Infrastructure:

192.100.27.x is iSCSI subnet - vLAN 56
192.128.23.x is the NFS Subnet vLAN 55

192.168.6.x(vLAN 25) is Management subnet. Used by Veeam Backup Server, vCenter and most of our ESXi hosts. But we still have some ESXi hosts that use our old management subnet 192.168.68.x
This is why we build a new Proxy with this subnet 192.68.68.x(vLAN 29)

Veeam Server I have(physical server):

1 interface(is 2 with NIC Teaming) for 192.168.6.x for Management Network.
1 Interface(also 2 with NIC Teaming) for 192.168.27.x using iSCSI initiator for the iSCSI connections.

Veeam Proxy(Virtual Machine):
1 interface with 192.168.68.x (vLAN 29) for Management Network.

This was the initial configuration and where Veeam Backup Server and Proxy never use the Direct NFS Access backup transport mechanism. All backups were running always with the option [nbd] for network block device (or network) mode, [hotadd] for virtual appliance mode.

Future Veeam Backup Infrastructure:

Hi,

Mounting NFS in a Windows Server is outside of Veeam. Is not Veeam related task.

This is just adding/mounting a NFS Share into a Windows Server. That you should configure in your NAS and then mount in the Windows. Then you can use as a Veeam Backup Repository

Hi,

I did also change both Designs, hope now have a better quality.

Using the Hyper-V Manager requires administrator rights. This guide shows how to add shortcuts and Start Screen tiles for normal users to quickly connect to local virtual machines rather than using the otherwise recommended Remote Desktop connection.
