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).
It’s that time of the year again…again! Pure Storage is back at VMworld in Barcelona.
Before we get into what’s happening at Barcelona, let’s recap a bit what happened in the US conference. As the best way to look to the future sometimes is to analyze the past.
Also check out this panel session I did with Rubrik on VMworld US.
VMware Cloud on AWS was once again a major topic–this is increasingly getting more attention and something we are paying a close eye on. The most important step around this for Pure is our new offering that is now fully GA, called Cloud Block Store. Our FlashArray software (Purity) now fully running AWS. See my posts here and here on that.
VMware Cloud Foundations. This is the basis for pretty much all automated VMware stacks–SDDC manager allows you to deploy vCenter, NSX, vRealize (etc. etc.) and of course their lifecycles. SDDC Manager (the management point of vCF) provides the ability to create on “management” domain–this is where all of the VMware services are deployed, and also one or more “workload” domains. Workloads domains are basically a new vCenter server–which gets hooked in via ELM. When deploying a workload domain the storage options used to be only be vSAN or NFS. You could then add block after the fact. In the 22.214.171.124 release, you can now choose Fibre Channel storage as the option. Check out our KB here on it. I expect to hear more about this in Barcelona.
Containers, K8s, and more containers. VMware’s work since the Heptio acquisition has not slowed down. I would be fairly comfortable saying that the announcement of Project Pacific and Project Tanzu were the talk of the town during and certainly after VMworld. I have no doubt this will bubble up more in Barcelona. The use case around First Class Disks and vVols I think is particularly intriguing.
vRealize Automation Cloud and vRealize 8.0. vRealize Automation 8.0 is now GA. There are two major things here to unpack. First VMware Cloud Automation Services was renamed to vRealize Automation Cloud. This in and of itself doesn’t mean anything (VMware loves to name things) but what is actually important about that is the “traditional” vRealize Automation set. vRealize Automation 8 is now entirely based on the features/design/architecture of vRealize Automation Cloud. Meaning that what vRAC offers is what vRA on-premises offers (same tools, integrations, features). This makes choosing between the two easier (one question to ask, do I want to host it, or do I want VMware to?). I expect details on this to be expanded in Barcelona.
vVols. Did you think I wouldn’t bring this up?! Of course I would. vVols is coming back in a big way, and in no small part due to VMware’s renewed push on vVols in their products and with their partners. The automation, integration, and benefits of vVols are making more and more sense these days. VMware gets that, and so do the storage partners. A major topic around vVols is Site Recovery Manager support. Expect to see more vendors talking about that as they furiously work on vVol replication support.
A few months back I published a new PowerShell cmdlet for installing the Pure Storage vSphere Client Plugin. Get-PfavSpherePlugin and Install-PfavSpherePlugin. This works quite well and we’ve had a fair amount of use of it so far, but another place we are certainly investing in right now is vRealize Orchestrator and continuing to enhance our plugin. Filling in any gaps around workflows and actions, especially on initializing an environment is important.
One of those gaps was installing the vSphere Plugin. One common use case we have seen around vRO is day 0 config, but day 2 stuff is done in vCenter (deploying VMs, datastores, etc). So the vSphere Plugin comes in handy here. So how do I install it from vRO?
One of the major advantages we have seen with VVols is making a virtual disk a first class citizen on the array. We can restore, copy, replicate them (and their VMs) as storage objects were meant to be restored, copied, replicated etc.
Though one thing about virtual disks is that by default–they are not first class citizens in vSphere, VVols or otherwise. To create one, it has to be associated with a VM.
To retrieve one in PowerCLI (for example) get-harddisk requires a datastore or a VM to return a result:
About 6 months ago, my esteemed colleague Barkz blogged about our path forward with PowerShell. We have an official PowerShell SDK for managing the FlashArray–but it is limited to that: doing stuff to the FlashArray.
So to add value and make managing it within context of the layers you actually manage your infrastructure from (VMware, Microsoft, etc.) we created some value-add PowerShell modules to make it easier. Barkz talks about them here:
This post is somewhat specific to Pure Storage–the cmdlets of course are universal, but behaviors may not correlate to your storage array. So if you are using VVols on a non-Pure array, certainly consult your vendor.
Furthermore, this is certainly specific to PowerCLI when it comes to the commands. With that being said, the fundamentals on how this works with Pure is common for all orchestration tools, so you should be able to use this information for other tools. Though of course the cmds/syntax will be different.
Hello there! The FlashArray and FlashBlade products from Pure have always had a REST API service built in–this REST service allows you to manage, provision, and pull raw statistics from the array.
But there are two pieces missing:
You need to iterate through each array if you want to intelligently place a volume on it (or find a volume or whatever)
They only offer raw statistics–you need to do some crunching possibly to get what you want. Create projections and forecast, find how busy an array is, etc.
Luckily this is what Pure1 does for you. Every customer has access to our Pure1 web tool. This is something we host, all of your dial-home information gets fed into it. We use that information to figure out how “busy” an array is, when it will fill up from a capacity or performance perspective and much more. We now offer a REST API for Pure1 as well, so you can do some one-stop shopping for the information you need, that the arrays cannot natively provide.
One of the fundamental features of the operating environment running on the FlashArray™ is the fact that the same software can run on many different hardware implementation of the FlashArray. This is one of the reasons that we can offer hardware Non-Disruptive Upgrades or when we introduce new features (even things as expansive as VVols) we can support it on older hardware. We support VVols going back to the FA 420-an array that was introduced before I joined Pure Storage® 4.5 years ago.
Furthermore, we have been having increasing conversations around the public cloud. Not just running applications in it, but moving data to and from it. DRaaS (Disaster Recovery as a Service) is an increasingly talked about use case. VMware Cloud in AWS is getting more and more attention at VMworld, and in general. We, at Pure get it. Will everything go to public cloud? No. Certainly not. Will everything stay on-premises? Also, of course not. Some customers will. Some will not at all. Many (most?) will use both in some capacity. So enabling data mobility is important.
