ActiveDR with NFS Datastores – FlashArray Configuration (Part 2)

Hello- this is part 2 in the series of blogs on ActiveDR + NFS datastores. In part 1, I introduced the two technologies to give you a background on them. In this blog I’ll be covering how to connect ActiveDR to an NFS file system that’s backing an NFS datastore.

For the purposes of this blog, I am using Pure Storage’s remote vSphere plugin. In general, I strongly recommend installing and using this plugin to manage your FlashArray(s) more easily from the vSphere GUI. Additionally, I’ve made a demo video that covers the steps covered here as well as the failover steps covered in part 3.

The first step is to establish an ActiveDR replication relationship between two arrays. While ActiveDR on block is continuous and can replicate as often as 1 second, ActiveDR on File currently has a minimum replication interval of 5 minutes.

On FlashArray, a pod is a management container containing a group of volumes that can be stretched or linked between two FlashArrays (page 132). ActiveDR uses pods to manage replication between arrays. First, we’ll create a pod on the source FlashArray by left clicking (1) Storage, then left clicking (2) Pods then left clicking the (3) + to create a new pod. Give it a (4) Name then left click (5) Create.

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.

Managing vVol Storage Policies with PowerShell

I just posted about some new cmdlets here:

New vVol Replication PowerShell Cmdlets

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

New vVol Replication PowerShell Cmdlets

Happy New Year everyone! Let’s work to make 2021 a better year.

In furtherance of that goal, I have put out a few new vVol-related PowerShell cmdlets! So baby steps I guess.

The following are the new cmdlets:

Basics:

Get-PfaVvolStorageArray

Replication:

Get-PfaVvolReplicationGroup
Get-PfaVvolReplicationGroupPartner
Get-PfaVvolFaultDomain

Storage Policy Management:

Build-PfaVvolStoragePolicyConfig
Edit-PfaVvolStoragePolicy
Get-PfaVvolStoragePolicy
New-PfaVvolStoragePolicy
Set-PfaVvolVmStoragePolicy

Now to walk through how to use them. This post will talk about the basics and the replication cmdlets. The next post will talk about the profile cmdlets.

What’s New in Purity 6.0: ActiveDR

I have already posted about ActiveDR briefly here:

Pure Storage Data Protection Part II: FlashArray Replication Options

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.

PowerCLI and VVols Part VIII: Running a Failover–Planned Migration

In the previous post in this series I explored how to run a VVol-based test failover of a virtual machine. Now I will walk through running an actual failover.

There are two types of failovers; a planned migration (everything is up an running) and a disaster recovery failover (part or all of the original site is down).

For this post, I will start with running a planned migration.

PowerCLI and VVols Part VI: Running a Test Failover

This post I will talk about using PowerCLI to run a test failover for VVol-based virtual machines. One of the many nice things about VVols is that in the VASA 3.0 API this process is largely automated for you. The SRM-like workflow of a test failover is included–so the amount of storage-related PowerShell you have to manually write is fairly minimal.

Semi-transparent failover with VMFS and Active/Passive Replication

So in a blog series that I started a few weeks back (still working on finishing it), I wrote about managing snapshots and resignaturing of VMFS volumes. One of the posts was dedicated to why I would choose resignaturing over force mounting almost all of the time.

An obvious question after that post is, well when would I want to force mount? There is a situation where i think it is a decent option. A failover situation where the recovery site is the same site as the production site, in terms of compute/vCenter. The storage is what fails over to another array. This is a situation I see increasingly common as network pipes are getting bigger.

Understanding the FlashArray Replication Connection Key

A question came up in a today at work that I answered and I thought it might be a good topic for a quick blog post:

How do you change your connection key for FlashArray replication?

The question misunderstands what the connection key actually is, so let me explain.

When you connect one FlashArray to another, you need three pieces of information:

The FQDN or IP for the management address of the remote array
The FQDN or IP for the replication address of the remote array
A connection key

Site Recovery Manager and Raw Device Mappings (RDMs)

Somewhat surprisingly I have been getting a fair amount of questions in the past few months concerning VMware vCenter Site Recovery Manager and Raw Device Mappings (RDMs) and using this with Pure Storage. Common question is whether or not we support this (we do) but more commonly it is about how it works. There is a bit of a misunderstanding on how they differ or do not differ from VMFS management in SRM. So figured I would put a post out to explain this. Old topic somewhat, but worth reviewing for those newer SRM customers. Plus, I haven’t found a whole lot of on-point posts anywhere, so why not?
