This is the start of many blog posts around the recent Purity 5.0 release. I figured I would start with one that doesn’t require an upgrade of Purity to even get!

Alongside Purity 5.0, we released the 3.0 version of theFlashArray plugin for the vSphere Web Client. This is bundled in Purity 5.0, so if you upgrade any one of your FlashArrays you can then use it to upgrade the plugin in one or all of your vCenters.

Let me be clear though–if you want to use VVols or ActiveCluster you need Purity 5.0. Without Purity 5.0, you can use the 3.0 plugin of course, but you can only use non-VVol or non-ActiveCluster features.

Release Notes

A few notes.

• This will be our last release of the plugin for the flash/flex-based vSphere Web Client. All new features and versions will be solely for the HTML-5 interface after this release. Look for HTML-5 support releases to begin in 2018.
• We no longer support vCenter 5.1. We actually block install of the plugin to 5.1 environments in the GUI installer.
• You do not need to upgrade to Purity 5.0 to use/or get the 3.0 plugin. Support can load it onto an array running older Purity if you prefer.

Install

To install/upgrade, log into you FlashArray GUI and go to the settings panel and then software.

Then choose vSphere Plugin to connect to a vCenter.

Then enter administrative credentials.

Then upgrade! Or install new:

If you want to install it to more than one vCenter, just simply disconnect and reconnect to another vCenter. And repeat as needed.

New Features

There are quite a few new features/enhancements.

• VMFS-6 provisioning.
• iSCSI auto-configuration
• Add existing datastore to cluster
• Rescan parallelism
• Virtual Volume support
• ActiveCluster provisioning support
• General usability enhancements and fixes

VMFS-6 support

Now when you right-click on a host or cluster the Create new Datastore wizard will have the VMFS-6 option. This requires the host you clicked on to be 6.5, or the cluster to have ESXi 6.5 hosts.

iSCSI Configuration

Another new feature is iSCSI configuration. This exists in two places, either when you are creating a new host group or by itself.

This feature does the following:

• Takes in a FlashArray you choose and finds the iSCSI target IPs
• Creates a software iSCSI adapter if it does not exist on the target host.
• Adds the FlashArray iSCSI target IPs as dynamic iSCSI targets
• Sets best practices on those targets (delayedAck to false and loginTimeout to 30)

If the adapter already exists, it skips that step. If the target already exists, it skips that step. If the best practices are already set it skips it. So if you preconfigured something, the process will not fail–it will simply move on.

This feature can be used when creating a new host group. So right-click on a vCenter cluster, choose Pure Storage, then Add Host Group.

Choose a FlashArray, then iSCSI and keep the option “Configure iSCSI initiators on hosts”. This is the new option that invokes this feature.

If selected, the plugin will get the FlashArray iSCSI targets and then add them to the software iSCSI adapter (which it will create if it is not there) on each ESXi host and then set the best practices. It will do this for each ESXi host in the cluster.

Then the plugin will create the hosts on the FlashArray for each ESXi  host in the cluster and add the IQN of each respective ESXi host. Then create a host group with the specified name (defaults to cluster name) and adds the hosts to it.

This process can also be invoked before or after a host group has been created. Right-click on a host or a cluster and choose Pure Storage then Configure iSCSI.

A window will pop-up where you can choose one or more FlashArrays.

When you click Configure, the plugin will iterate through all of the hosts in the cluster (or just the host if that is what you originally clicked on) and add the sofware iSCSI adapter if it does not exist, then adds the iSCSI targets and set best practices. It will iterate through that for each selected FlashArray.

This makes setting up iSCSI super easy and fast.

Add Existing Datastore to Hosts

This is pretty straight-forward. Right-click on a FlashArray VMFS datastore and choose Mount on additional Hosts.

This will then allow you to choose a new host or entire cluster (or a selection of them) for an existing datastore to be added to. If you choose a cluster which already has a host that sees it, the process will then add it to each host directly. If you choose a whole cluster and no host has the datastore yet, it will be added at the host group level.

Choose the hosts or cluster you want to add it to by selecting it and click Mount. Hosts that already see the VMFS, are marked with a grayed out check.

The process will then connect the volume on the FlashArray as needed and then rescan the proper hosts.

Rescan Parallelism

This is more of an improvement than a new feature. But it is an important one for large environments. Previously, just like the standard rescan in VMware tools, hosts are rescanned in a serial fashion, so one rescan would not start until the previous host finished. This could then take a long time in large environments.

So what we have changed is that we now issue rescans in parallel. So this should dramatically improve VMFS provisioning time. All plugin work flows that use rescans have been improved to use this.

ActiveCluster Support

In Purity 5.0, we introduced support for our Active/Active replication called ActiveCluster.

In provisioning we support adding a new VMFS to a pod, by entering the pod name as a prefix. In the HTML-5 version of the plugin, we intend to make pods first class citizens so this can be much cleaner.

Choose a name and prefix it with the pod name and two colons:

And the VMFS datastore is created and the new FlashArray volume is in the pod.

Virtual Volume Support

To re-iterate: you cannot use VVols by just upgrading to the 3.0 plugin. You do need Purity 5.0 for these features.

This is the biggest part of the plugin release and really deserves its own post, which it will get. So I will add some highlights of plugin 3.0 support for VVols. Look for a detailed post soon.

• Register VASA providers. Automates the process of registering FlashArray VASA providers redundantly to each vCenter
• Import storage policies. Takes in FlashArray protection groups and creates Storage Policy Based Management VM storage policies from them. Replication config, snapshot intervals, retentions etc.
• Mount VVol datastores and provisions protocol endpoints
• Create unmanaged VVol FlashArray snapshot of a VVol-based virtual disk
• Import any VVol and VVol snapshot (which are respectively FlashArray volumes and FlashArray snapshots) to any other VM
• Overwrite any VVol from a source VVol or snapshot on the same array on the same or different VM. Uses purevol copy, so it is basically instant
• VVol undelete. If you accidentally deleted a VVol-based virtual disk, we can automatically re-add it back in the plugin
• Virtual disk to VVol correlation–a new screen showing the VM’s details

Stay tuned for a lot more on the VVol stuff!

Other enhancements

There have been quite a few usability improvements, bug fixes etc. Most not quite worth writing here, but one that I like is the quick-click button in the home drop down to quickly get to the plugin configuration screen:

And as with all plugin features, if you want to use RBAC you can enable/disable features for users as needed with vCenter permissions we add during plugin install:
