Pure Storage’s vROps Management Pack ™ 3.2.0 – New Features and Changes

Pure Storage recently launched a new management pack for vROps that had a number of important fixes and some changes to the interface. You can download it here and find the full release notes here. What’s new?

  • Interface changes
    • Updated icons
    • Restructuring of Pure Storage objects in the Object view of vROps
  • Add Offload Snapshot capacity metric
  • Add FlashArray Software™ version property

Let’s go over the interface changes first. If you navigate to Environment -> Object Browser -> Pure Storage FlashArray -> FlashArray Resources -> PureStorage World and expand an array, the layout will look quite different than what was there before. For starters, the icons have almost all been updated to mirror what you would expect to see on a modern FlashArray Purity version (or vCenter if that is a vCenter object). We made this change to make the vROps management pack experience as close to the FlashArray experience as possible.

Additionally, we moved the structure of the objects around to be more consistent with what you’d expect from the FlashArray. No objects were removed and the same object can be listed in multiple places where it makes sense (for example, if you expand a Hosts group, you will see the pertinent volumes there as well as under the Volumes group).

Next, we’ve added the Offload Snapshot capacity metric in this version as well as a FlashArray Offload Target object. The Offload Target object is visible under Protection and you can see the current space used by that Offload Target in the badge for that object; additionally, there is a Capacity metric for this object that shows historical consumption.

Lastly, you can now retrieve the Purity version of the array directly from vROps to help plan your FlashArrays’ upgrades. This information is found by selecting a FlashArray and going to Metrics -> Properties -> Details -> Purity Version.

Native Pure Storage FlashArray™ File Replication – Purity 6.3


With the release of Purity 6.3, Native FA File replication has been added to the Pure Storage FlashArray™ software. This adds an often important feature to the FA File folder redirection solution I wrote about last year. Pure Storage is referring to this feature as ActiveDR for File Services.

ActiveDR for File Services is a useful feature if you’ve set up or are going to set up folder redirection on FA File and you would like the file data to be replicated asynchronously to a different array, whether that FlashArray hardware is at the same site or a different one. This feature is included with FlashArray.

This allows you to use your FlashArray for native block and file workloads that need the protection that replication provides and allow you to benefit from the great data reduction rate that FlashArray is known for with those replicated file sets.

Now, if you lose a site or an array for some reason, the file workload you have hosted on FA File can be recovered natively on FlashArray easily and quickly.

There are some differences between file and block workloads when it comes to ActiveDR replication. You can read more in the ActiveDR for File Services section of this Pure KB.

What’s New in vSphere 7.0 U2 Storage: Creating a File Repository on a vVol Datastore

This feature has many names. Creating a larger config vVol. Creating a sub-vVol datastore. Creating an ISO repository. Etc.

In 7.0U2, VMware added a new feature that supports creating a custom size config vVol–while this was technically possible in earlier releases, it was not supported. Also, I should note that this is not supported by all vVol vendors, so of course speak to your vendor first.

First to review what a config vVol is check out this post:

What is a Config VVol Anyways?

In short, it is a mini VMFS that gets created when you create a directory in a vVol datastore (most commonly created by creating a new VM). This defaults to 4 GB in size. Enough to store the general VM files; some logs, VMDK pointers, vmx file, and some other frivolities.

The issue though is that this was not large enough to store large things like ISOs or vib files or whatever. So if you tried to upload something to a vVol datastore folder it would fail with an out-of-space issue. And you cannot upload to the root of a vVol datastore because a vVol datastore is not a file system. So you had to use VMFS or NFS to store those objects.

This is no longer the case.

Pure Storage Plugin for the vSphere Client 4.5.0 Release

Howdy doody folks. Lots of releases coming down the pipe in short order and the latest is well the latest release of the Pure Storage Plugin for the vSphere Client. This may be our last release of it in this architecture (though we may have one or so more depending on things) in favor of the new preferred client-side architecture that VMware released in 6.7. Details on that here if you are curious.

Anyways, what’s new in this plugin?

The release notes are here:

https://support.purestorage.com/Solutions/VMware_Platform_Guide/Release_Notes_for_VMware_Solutions/Release_Notes%3A_Pure_Storage_Plugin_for_the_vSphere_Client#4.5.0_Release_Notes

But in short, five things:

  1. Improved protection group import wizard. This feature pulls in FlashArray protection groups and converts them into vVol storage policies. This was, rudimentary at best previously, and is now a full-blown, much more flexible wizard.
  2. Native performance charts. Previously performance charts for datastores (where we showed FlashArray performance stats in the vSphere Client) was actually an iframe we pulled from our GUI. This was a poor decision. We have re-done this entirely from the ground up and now pull the stats from the REST API and draw them natively using the Clarity UI. Furthermore, there are now way more stats shown too.
  3. Datastore connectivity management. A few releases ago we added a feature to add an existing datastore to new compute, but it wasn’t particularly flexible and it wasn’t helpful if there were connectivity issues and didn’t provide good insight into what was already connected. We now have an entirely new page that focuses on this.
  4. Host management. This has been entirely revamped. Initially host management was laser focused on one use case: connecting a cluster to a new FlashArray. But no ability to add/remove a host or make adjustments. And like above, no good insight into current configuration. The host and cluster objects now have their own page with extensive controls.
  5. vVol Datastore Summary. This shows some basic information around the vVol datastore object

First off how do you install? The easiest method is PowerShell. See details (and other options) here:

Managing vVol Storage Policies with PowerShell

I just posted about some new cmdlets here:

Also in that release are a few more cmdlets concerning storage policy creation, editing, and assignment. They were built to make the process easier–the original cmdlets and their use is certainly an option–and for very specific things you might want to do they might be necessary, but the vast majority of common operations can be more easily achieved with these.

As always, to install run:

Install-Module PureStorage.FlashArray.VMware

Or to upgrade:

Update-Module PureStorage.FlashArray.VMware

These modules are open source, so if you just want to use my code or open an RFE or issue go here:

https://github.com/PureStorage-OpenConnect/PureStorage.FlashArray.VMware/

For detailed help on a cmdlet, run Get-Help

The following are the new cmdlets:

Basics:

  • Get-PfaVvolStorageArray

Replication:

  • Get-PfaVvolReplicationGroup
  • Get-PfaVvolReplicationGroupPartner
  • Get-PfaVvolFaultDomain

Disk.DiskMaxIOSize and the Blue Screen of Death

While the title of this post does sound like a halfway decent Harry Potter novel, this is far more nefarious. Pure Storage, like many other vendors have a best practice around lowering the Disk.DiskMaxIOSize setting on ESXi hosts when using UEFI boot for your Windows VMs. Why? Well:

Yes not having it set in a few situations would cause BSOD. First off, why?

What’s New in Purity 6.0: ActiveDR

I have already posted about ActiveDR briefly here:

I wanted to go into more detail on ActiveDR (and more) in a “What’s New” series. One of the flagship features of the Purity 6.0 release is what we call ActiveDR. ActiveDR is a continuous replication feature–meaning it sends the new data over to the secondary array as quickly as it can–it does not wait for an interval to replicate.

For the TL;DR, here is a video tech preview demo of the upcoming SRM integration as well as setup of ActiveDR itself

But ActiveDR is much more than just data replication is protects your storage environment. Let me explain what that means.

Default FlashArray Connection With PowerShell

In the VMware Pure PowerShell module (PureStorage.FlashArray.VMware) there is a default array connection stored in a global variable called $Global:DefaultFlashArray and all connected FlashArrays in $Global:AllFlashArrays. The VMware/Pure PowerShell module automatically uses what is in the “default” variable.

The underlying “core” Pure Storage PowerShell module (PureStoragePowerShellSDK) does not yet take advantage of global connections. So for each cmdlet you run, you must pass in the “array” parameter. For example to get all of the volumes from an array:

Kind of annoying if you are interactively running commands and only have one array connection you care about (or one that you primarily care about).
