How to Supercharge PowerShell Objects for Hyper-V

The best thing about working with PowerShell is that everything is an object. This makes it easy to work with the properties of the thing you need to manage without a lot of scripting or complex text parsing. For example, when using the Hyper-V PowerShell module it is trivial to get specific details of a virtual machine.

Getting virtual machine properties with PowerShell

There are many properties to this object. You can pipe the object to Get-Member to see the definition or Select-Object to show all properties and their values.

But what you want more? I usually do. For example, there is a CreationTime property for the virtual machine object. I’d like to be able to report on how old the virtual machine is. For a one-and-done approach I could write a command like this:

Defining a new custom property

Or maybe I’d like the MemoryAssigned value to be formatted in MB.

Defining a custom property for assigned memory

The syntax is to define a hashtable with 2 keys: Name and Expression. The Name value is what you want to use for your custom property name and the Expression is a PowerShell scriptblock. In the scriptblock you can run as much code as you need. Use $_ to reference the current object in the pipeline. In the last example, PowerShell looks at the MemoryAssigned value for the CentOS virtual machine object and divides it by 1MB. Then it moves on the DOM1 and divides the value (2147483648) by 1MB to arrive at 2048 and so on.

Using Select-Object this way is great for your custom scripts and functions. But suppose I want to get these values all the time when working with the object in the console interactively. I don’t want to have to type all that Select-Object code every single time. Fortunately, there is another approach.

PowerShell’s Extensible Type System

PowerShell has an extensible type system. This means you can extend or modify the type definition of an object. PowerShell takes advantage of this feature all the time. Many of the properties you’ve seen in common objects have been added by Microsoft. You can use the Get-TypeData cmdlet to view what additions have been made to a given type.

default extensions to the virtual machine object

You can see these additions with Get-Member.

Viewing the type additions

By now, you are thinking, “How can I do this?”. The good news is that it isn’t too difficult. Back in the PowerShell stone age you would have had to create a custom XML file, which you can still do. But I think it is just as easy to use the Update-TypeData cmdlet. I’ll give you some examples, but please take the time to read the full help and examples. One thing to keep in mind is that any type extensions you make last only as long as your PowerShell session is running. The next time you start PowerShell you will have to re-define them. I dot source a script file in my profile script that adds my type customizations.

Updating Type Data

The first thing you will need to know is the object’s type name. You can see that when piping to Get-Member.

When you define a new type you need to determine the membertype. This will be something like a ScriptProperty or Alias. A ScriptProperty is a value that is calculated by running some piece of PowerShell code. If you’ve created a custom type with Select-Object to test, as I did earlier, you will re-use that expression scriptblock. And of course, you need to define a name for your new property.

With this code, I’m defining a new script property called Age. The value will be the result of the scriptblock that subtracts the CreationTime property of the object from now. The one difference to note compared to my Select-Object version is that here use $this instead of $_.

I went ahead and also created an alias property of “Created” that points to “CreationTime”. If you try to create a type extension that already exists PowerShell will complain. I typically use -Force to overwrite any existing definitions. But now I can see these new type members.

Verifying new VM type extensions

And of course, I can use them in PowerShell.

Using the new type extensions in PowerShell

There’s really no limit to what you can do. Here is a script property that tells me when the VM started.

and here is some code that takes the memory properties and creates an ‘MB’ version of each one. I’m using some PowerShell scripting and splatting to simplify the process.

Now I have all sorts of information at my fingertips.

Taking advantage of all the new properties

As long as I run the Update-Typedata commands I will have this information available. In my PSHyperVTools module, which you can install from the PowerShell Gallery, it will add some of these type extensions automatically, plus a few more. You can read about it in the project’s GitHub repository.

Does this look like something you would use? What sort of type extensions did you come up with? What else do you wish you could see or do? Comments and feedback are always welcome.

Wanted – Cheap MacBook Pro

£100? No chance. Any MacBook that’s working and has the specs you’re after is £300 minimum, and the 8gb ram is always on the step up model up until newer generations.

I should add that I’m not looking to troll – I have a 15inch I’m looking to part with but it’s way out of your price range – hence me having a look at wht you were after.

How to Create and Manage Hot/Cold Tiered Storage

When I was working in Microsoft’s File Services team around 2010, one of the primary goals of the organization was to commoditize storage and make it more affordable to enterprises. Legacy storage vendors offered expensive products, often consuming a majority of the budget of the IT department and they were slow to make improvements because customers were locked in. Since then, every release of Windows Server has included storage management features which were previously only provided by storage vendors, such as deduplication, replication, and mirroring. These features could be used to manage commodity storage arrays and disks, reducing costs and eliminating vendor lock-in. Windows Server now offers a much-requested feature, the ability to move files between different tiers of “hot” (fast) storage and “cold” (slow) storage.

Managing hot/cold storage is conceptually similar to computer memory cache but at an enterprise scale. Files which are frequently accessed can be optimized to run on the hot storage, such as faster SSDs. Meanwhile, files which are infrequently accessed will be pushed to cold storage, such as older or cheaper disks. These lower priority files will also take advantage of file compression techniques like data deduplication to maximize storage capacity and minimize cost. Identical or varying disk types can be used because the storage is managed as a pool using Windows Server’s storage spaces, so you do not need to worry about managing individual drives. The file placement is controlled by the Resilient File System (ReFS), a file system which is used to optimize and rotate data between the “hot” and “cold” storage tiers in real-time based on their usage. However, using tiered storage is only recommended for workloads that are not regularly accessed. If you have permanently running VMs or you are using all the files on a given disk, there would be little benefit in allocating some of the disk to cold storage. This blog post will review the key components required to deploy tiered storage in your datacenter.

Overview of Resilient File System (ReFS) with Storage Tiering

The Resilient File System was first introduced in Windows Server 2012 with support for limited scenarios, but it has been greatly enhanced through the Windows Server 2019 release. It was designed to be efficient, support multiple workloads, avoid corruption and maximize data availability. More specifically to tiering though, ReFS divides the pool of storage into two tiers automatically, one for high-speed performance and one of maximizing storage capacity. The performance tier receives all the writes on the faster disk for better performance. If those new blocks of data are not frequently accessed, the files will gradually be moved to the capacity tier. Reads will usually happen from the capacity tier, but can also happen from the performance tier as needed.

Storage Spaces Direct and Mirror-Accelerated Parity

Storage Spaces Direct (S2D) is one of Microsoft’s enhancements designed to reduce costs by allowing servers with Direct Attached Storage (DAS) drives to support Windows Server Failover Clustering. Previously, highly-available file server clusters required some type of shared storage on a SAN or used an SMB file share, but S2D allows for small local clusters which can mirror the data between nodes. Check out Altaro’s blog on Storage Spaces Direct for in-depth coverage on this technology.

With Windows Server 2016 and 2019, S2D offers mirror-accelerated parity which is used for tiered storage, but it is generally recommended for backups and less frequently accessed files, rather than heavy production workloads such as VMs. In order to use tiered storage with ReFS, you will use mirror-accelerated parity. This provides decent storage capacity by using both mirroring and a parity drive to help prevent and recover from data loss. In the past, mirroring and parity would conflict and you would usually have to select one of the other.  Mirror-accelerator parity works with ReFS by taking writes and mirroring them (hot storage), then using parity to optimize their storage on disk (cold storage). By switching between these storage optimizations techniques, ReFS provides admins with the best of both worlds.

Creating Hot and Cold Tiered Storage

When configuring hot and cold storage you get to define the ratio of the hot and cold storage. For most workloads, Microsoft recommends allocating 20% to hot and 80% to cold. If you are using high-performance workloads, consider having more hot memory to support more writes. On the flip-side, if you have a lot of archival files, then allocate more cold memory. Remember that with a storage pool you can combine multiple disk types under the same abstracted storage space. The following PowerShell cmdlets show you how to configure a 1,000 GB disk to use 20% (200 GB) for performance (hot storage) and 80% (800 GB) for capacity (cold storage).

Managing Hot and Cold Tiered Storage

If you want to increase the performance of your disk, then you will allocate a great percentage of the disk to the performance (hot) tier. In the following example we use the PowerShell cmdlets to create a 30:70 ratio between the tiers:

Unfortunately, this resizing only changes the ratios of the disks but does not change the size of the partition or volume, so you likely also want to change these using the Resize-Volumes cmdlets.

Optimizing Hot and Cold Storage

Based on the types of workloads you are using, you may wish to further optimize when data is moved between hot and cold storage, which is known as the “aggressiveness” of the rotation. By default, the hot storage will use wait until 85% of its capacity is full before it begins to send data to the cold storage. If you have a lot of write traffic going to the hot storage then you want to reduce this value so that performance-tier data gets pushed to the cold storage quicker. If you have fewer write requests and want to keep data in hot storage longer then you can increase this value. Since this is an advanced configuration option, it must be configured via the registry on every node in the S2D cluster, and it also requires a restart. Here is a sample script to run on each node if you want to change the aggressiveness so that it swaps files when the performance tier reaches 70% capacity:

You can apply this setting cluster-wide by using the following cmdlet:

NOTE: If this is applied to an active cluster, make sure that you reboot one node at a time to maintain service availability.

Wrap-Up

Now you should be fully equipped with the knowledge to optimize your commodity storage using the latest Windows Server storage management features. You can pool your disks with storage spaces, use storage spaces direct (S2D) to eliminate the need for a SAN, and ReFS to optimize the performance and capacity of these drives.  By understanding the tradeoffs between performance and capacity, your organization can significantly save on storage management and hardware costs. Windows Server has made it easy to centralize and optimize your storage so you can reallocate your budget to a new project – or to your wages!
