Features I Use Regularly in Pure’s vSphere Plugin

Today I want to tell to you about what I use the vSphere plugin for regularly in my lab to hopefully help you get more value out of your existing Pure array and tools. The assumption of this guide is that you already have the vSphere plugin installed (follow this guide if you don’t currently have it installed or would like to upgrade to a more feature-rich remote plugin version). Our vSphere plugin release notes KB covers the differences between versions. If you aren’t sure what version you want, use the latest version.

Why should you care about the vSphere plugin and why would I highlight these workflows for you? Pure’s vSphere plugin can save you a significant amount of time in the configuration/management of your vSphere+FlashArray environment. It can also greatly reduce the barriers to success in your projects by reducing the steps required of the administrator for successful completion of a workflow. Additionally, you might currently be using the vSphere plugin for a couple of workflows but didn’t realize all of the great work our engineers have put into making your life easier.

I am planning to write more blogs on the vSphere plugin and the next one I plan to write is on the highest value features that exist in current vSphere plugin versions.

Create and Manage FlashArray Hosts and Host Group Objects

If you’re currently a Pure customer, you have likely managed your host and host group objects directly from the array. Did you know you can also do this from the vSphere plugin without having to copy over WWNs/IPs manually? (1) Right-click on the ESXi cluster you want to create/manage a host or host group object on, (2) hover over Pure Storage, then (3) left-click on Add/Update Host Group.

In this menu, there are currently Fibre Channel and iSCSI protocol configuration options. We are currently exploring options here for NVMe-oF configuration; stay tuned by following this KB. You can also check a box to configure your ESXi hosts for Pure’s best practices with iSCSI, making it so you don’t have to manually configure new iSCSI ESXi hosts.

FlashArray VMFS Datastore and Volume Management (Creation and Deletion)

There are a lot of options for VMFS volume management in the plugin. I’ll only cover the basics: creation and deletion.

When you use the plugin for datastore creation, the plugin will create the appropriate datastore in vSphere, the volume on the FlashArray, and it will connect the volume to the appropriate host(s) and host group objects on the FlashArray. (1) Right-click on the pertinent cluster or host object in vSphere, (2) hover over Pure Storage and finally (3) left-click on Create Datastore. This will bring up a wizard with a lot of options that I won’t cover here, but the end result will be a datastore that has a FlashArray volume backing it.

The great thing about deleting a datastore from the plugin is that there are no additional steps required on the array to clean up the objects. This is the most satisfying workflow for me personally because cleanup in a lab can feel like it’s not a good use of time until I’ve got hundreds of objects worth cleaning up. This workflow enables me to quickly clean up every time after I’ve completed testing instead of letting this work pile up.

(1) Right-click the datastore you want to delete, (2) hover over Pure Storage and (3) left-click on Destroy Datastore. After the confirmation prompt, the FlashArray volume backing that datastore will be destroyed and is pending eradication for whatever that value is configured on the FlashArray (default 24 hours, configurable up to 30 days with SafeMode). That’s it!

FlashArray Snapshot Creation

One of the benefits of FlashArray is its portable and lightweight snapshots. The good news is that you can create these directly from vSphere without having to log into the FlashArray. It’s worth mentioning that although the snapshot recovery workflows built into the vSphere plugin (vVols and VMFS) are far more powerful and useful when you really need them, I’m covering what I use regularly and I rarely have to recover from snapshots in my lab. I try to take snapshots every time I make a major change to my environment in case I need to quickly roll-back.

There are two separate workflows for snapshot creation: one for VMFS and one for vVols. The granularity advantage with vVols over VMFS is very clear here- with VMFS, you are taking snapshots of the entire VMFS datastore, no matter how many VMs or disks are attached to those VMs. With vVols, you only have to snapshot the volumes you need to, as granular as a single disk attached to a single VM.

With VMFS, (1) right click on the datastore, (2) hover over Pure Storage and (3) left click on Create Snapshot.

For a vVols backed disk, from the Virtual Machine Configure tab, navigate to the Pure Storage – Virtual Volumes pane, (1) select the disk you would like to snapshot and (2) click Create Snapshot.

A prompt will pop up to add a suffix to the snapshot if you’d like; click on create and you’ve got your FlashArray snapshot of a vVols backed disk created!

Stay tuned for a blog on the vSphere plugin features you might not know about that, like the above, can save you a significant amount of time and effort.

Pure Storage vSphere Remote Plugin™ 5.1.0 launch: vVol Point-in-Time Recovery

We are excited to announce the launch of the latest version of Pure Storage’s remote vSphere plugin, 5.1.0. It includes a number of bug fixes PLUS a highly sought after feature: vVols VM point-in-time (PiT) recovery!

Why am I excited about this feature?

With vVol PiT VM recovery, you can now easily recover an entire VM that was accidentally deleted (and eradicated) or you can restore the state of a VM back to a point in time that you took a snapshot from vCenter directly while using Pure’s vSphere plugin.

The requirements of this are Pure’s vSphere remote plugin 5.1.0 and Purity™ 6.2.6 or higher for PiT revert and for PiT VM undelete with a vVol VM that has had its FlashArray™ volumes eradicated from the FlashArray itself. If you’re undeleting a vVol VM that has not been eradicated yet, that functionality is present for Purity versions 6.1 and lower.

For PiT VM revert, you will also need to make sure that you have snapshots of all of the volumes associated with the vVol VM except swap- at least one data volume and one configuration volume.

For VM undelete before the volumes have been eradicated, you will need a snapshot of the vVol VM’s configuration volume.

For VM undelete after the vVol-backed VM has been eradicated, you’ll need a FlashArray protection group snapshot of all the VM’s data volumes, managed snapshots and configuration volumes.

Rather than rehash what my teammate Alex Carver has put a lot of work into, I’m just going to link to the KB and videos he created:

Download the new plugin (part of Pure’s OVA), read the release notes and test out vVol PiT recovery today! Like a lot of things, it’s better to have some understanding of what’s happening and why before needing something that might be part of your recovery process. Please note that you can also upgrade in-place from 5.0.0 to 5.1.0 (and future remote plugin releases) by following this guide.

vSphere Remote Plugin: .local vCenter Domains

Hello- Nelson Elam here! I’m a VMware Solutions Engineer at Pure Storage and wanted to make you aware of an issue we’ve seen crop up a couple of times recently with our vSphere Remote Plugin and provide a quick explanation.

If your vCenter uses a .local domain (vcenter.purestorage.local is one example), you might have seen the following 3 errors in Pure’s vSphere Remote Plugin in vCenter:

  1. In the FlashArray list page, the error “Error retrieving array list. Please try again later.” is returned.
    clipboard_eaaa133673603ef70ba1a091e33b493c7.png
  2. When trying to import arrays via Pure1, the error “Authenticate with Pure1 to use this feature” is returned despite previously successful registration with Pure1 through the plugin.
  3. When adding an array manually, a “no permissions” error is returned.

Resolution:
To resolve this, follow step 14 from the Online Deployment Procedure for the remote plugin by running this command after customizing it to your environment:
pureuser@purestorage-vmware-appliance:~$ puredns setattr --search {your .local domain} --nameservers {ip or FQDN of DNS server}

So what’s going on here? When the OVA where you deployed the Remote vSphere Plugin tries to reach out to your vCenter with a .local domain suffix, it can’t resolve the DNS address unless you’ve provided the appropriate search domain for the OVA and will return different errors depending on where you are trying to interact with it in vCenter.

Luckily this is a simple fix despite the seemingly unrelated errors that pop up. Hopefully this was helpful!

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:
