Traditionally Windows VMs (virtual machines) in Azure would include a Windows Server Datacenter license. The cost of this license was built into the hourly/monthly fee for that VM. This made systems easy to roll out using the GUI wizards and made licensing a cinch. If you are moving existing virtual machine workloads to the cloud, this can be expensive since you paying again for licenses you’ve already purchased.
According to their new announcement, Microsoft says “now you can move your existing Windows Server licenses to Azure when you extend your datacenter to the cloud. With the Azure Hybrid Use Benefit, you can use on-premises Windows Server licenses that include Software Assurance to run Windows Server virtual machines in Azure at the base compute rate.” Continue reading

I am a worry wart when it comes to backing up data. For my critical systems, I never trust a single backup method, but rather I implement several different strategies for backup and disaster recovery. For the past two years, one of those methods has been using Veeam Backup and Recovery.
Traditionally, Veeam has been a product to backup virtual machines (VMs) hosted on either Hyper-V or VMware hosts. They specialized in backing up the entire VM to disk quickly and easily using encryption and/or deduplication. Daily backups are incremental, as they only backup the bits of virtual disks that actually changed since the last backup. This makes incremental backups very quick, and requires very little disk space compared to comparable solutions. The product also made it very easy to restore an entire VM to any host running the same hypervisor platform.

Exporting a Hyper-V VM (virtual machine) creates a full copy of that VM. This can be used as an easy way to create an ad-hoc backup or an archive. An export can also contain all of the existing checkpoints that exist, so it is a really helpful tool during deployments, migrations, and upgrades. Continue reading

Though often a less frequently used feature of Hyper-V, the import and export functions offer some very useful benefits. In Windows Server 2012 R2 these benefits get even better. I will explain how this functionality works, and why it is useful. I’ll also discuss how these functions are very different from the commonly used checkpoints in Hyper-V. Continue reading

Live Migration is the process of moving a virtual machine (VM) from one Hyper-V virtualization host to another Hyper-V host without any perceived downtime of the VM being moved. Continue reading

Microsoft has released the preview of Windows Server 2012 R2 to the public. This is available for download for users with a Live ID at Microsoft’s Windows Server 2012 Preview site.
If you’re not familiar with Microsoft’s “Preview Releases”, then let me explain a little. The preview is not a finished copy, but rather a beta version which contains most (if not all) of the features and improvements we should expect to see in the final version for GA (general availability).

As a seasoned virtualization expert (mostly with Hyper-V environments), I totally agree with the concept of building your VMs (virtual machines) and virtualization hosts to meet a particular need.
Often, I talk to SQL DBAs (database administrators) or Exchange administrators who swear that these platforms can NEVER be virtualized. This line of thinking is so wrong that Microsoft itself has bet their business around it (e.g., Office 365, Microsoft.com, etc.).
The most important piece of advice I give to virtualization newcomers is to treat a VM like you would a physical server. If a physical Exchange server needs 16GBs of memory and 4 CPUs, then building a VM with only a single virtual processor and 2GB of memory is going to result in a bad user experience, obviously.
HDD (hard disk drive) performance is always a concern with VMs. If you are creating a VM to run a disk intensive SQL server, then you will certainly care about your disk performance. With the more recent versions of Hyper-V, there is little noticeable performance reduction when choosing dynamically expanding VHD (virtual hard disk) vs. using a fixed size VHD. The big downside is that you now have to monitor and manage your storage on the host since your VMs can quickly consume physical space.
If extra disk performance is really needed, there is an option of using a pass-through disk. Pass-through disks will use an unused volume on the physical Hyper-V host as if that volume were its own. With pass-through disks you’ll get true hardware-level performance. The downside is that your VM is now tied to this physical storage making it difficult (or impossible) to migrate to a different host… so plan accordingly.

For mission critical systems, we often want to try to achieve the highest level of up time as possible, and the best disaster recovery strategy. Often this involves expensive software which replicates servers or data for failover purposes. This means Continue reading

One of the biggest limitations of Hyper-V in Windows Server 2008 R2 was that it didn’t support storing a Virtual Hard Disk (VHD) on physical disks larger than 2 TB. This was actually due to the sector size of the physical disk which was supported by Hyper-V. Larger disks tended to use 4096-byte sectors (also known as 4k sectors). Continue reading

When building high-performance Hyper-V host servers for a production environment, we often buy high-end servers with lots or memory and fast SAS (Serial Attached SCSI) or SSD (Solid State) drives. These drives are fast but usually expensive, especially after adding in RAID
redundancies. Continue reading

In the Hyper-V world, lots of us talk about Live Migration. That is where a virtual machine (VM) is moved from one host to another with no perceived downtime. The caveat is that both hosts need be configured to use the same shared storage (such as a SAN or external drive array). Continue reading
