Editor's Corner

This week's issue of WServerNews focuses on VMware by examining some of the cool things you can do with tags, a feature that was first introduced in vSphere 5.1. To take us through this topic we're pleased to have Rick Vanover as our guest contributor for this week's newsletter. Rick, who is also a Cisco Champion and vExpert, is the Director of Product Strategy for Veeam Software. Rick's IT experience includes system administration and IT management with virtualization being the central theme of his career recently. Uou can follow Rick on Twitter @RickVanover or @Veeam.

We also have a new Ask Our Readers question that Your Editor offers his own insights concerning but which we hope some smarter and more experienced readers may be able to elaborate further upon. And we've also updated our Conference Calendar with more upcoming conferences and training events for the coming months. Speaking of which we need some help finding any big IT conferences happening Australia, Asia, and India so if any of our newsletter readers in these areas can point us to some we'd be glad to update our Conference Calendar accordingly. And finally we have all of the usual tips, tools, links to tech tidbits and fun stuff, and our usual factoid for you to tease your brain with, so enjoy! And if you have any feedback on anything in this issue feel free to email us at wsn@mtit.com

And now on to our guest editorial by Rick Vanover…

 

vSphere Tags: No time like the present to start using them!

It seems like forever ago (and it was!) that VMware introduced vSphere tags. In vSphere 5.1, tags and categories were introduced as additional organizational constructs. This is in addition to things like folders (purely organization), resource pools, hosts, clusters, vApps, datastores, data centers and more. 

The tag and category framework is somewhat different however. Datastores for example can include VMs that reside on a datastore. Folders can include hosts and VMs. Resource pools are active management elements for VM resources (versus an organizational construct). Other constructs have their own characteristics but what is noteworthy is that any object can have a vSphere tag or category applied to it. 

This means that a tag or category can be applied to a host, cluster, network, VM, datastore, resource pool and many other types of objects in the vSphere infrastructure.

 

OK, now what do I do with tags?

In my role at Veeam, I've long advocated using vSphere tags for backup policy definition but also for assigning whether or not a workload is to be orchestrated for disaster recovery. This is a nice way to classify workloads in regards to their availability, but this is just a start. 

Before we go too far with tags, the number one rule is to make them self-describing. Whatever you do, please don't make categories like "Sample Category" or tags like "Tag1". Much more relevant categories and tags are going to help you (and others) later. Take for example a category name like "Backup Policies" with tags like "24 hour RPO", "4 hour RPO" and "1 hour RPO". This makes building backup policies so much easier. Additionally, consider a tag called "No Backup" where something is explicitly agreed upon that it doesn't need a backup – such as a development or test system. I always can do better at tag and category naming, but here is a view in my shared lab of an active configuration:

 Image

I have spoken to many organizations who have taking the tagging and category process very seriously and it is baked into their day-to-day processes. This helps with visibility, availability, deployment and more. Here are a few tips on how to use vSphere tags if you are not already. try my second suggestion i.e. by throwing more money at the problem and trading up for a more expensive switch from the same vendor, one that had a larger buffer. The result? The problem went away.

Deployment: When a VM is deployed, it is advised to have a few tags applied with the main options defined. An tag within a category for "Backup Policy", a tag within a policy for "DR Policy", a tag within a policy for "Compliance and Audit Status" for systems in-scope of an audit process. Many organizations bake this into automation options of when a VM is deployed from a template. This also can be manually applied.

Application status: In addition to the status mentioned above regarding Compliance and Audit, one popular tag and category framework is to identify critical applications. I have a category called "T1-PPI-Applications" this indicates Tier 1, PPI (Personal Protected Information) and that it is applications. This is one example where other categories could be made such as Tier-2 or non-PPI and other situations that make sense in an organization. Looking at the tags, you'll see one application (ZincBlast) is tagged within that category:

Image

Storage information: This can work in conjunction with VMware Storage Policy-Based Management (SPBM), but one good use case for tags and categories is to indicate the type of storage in use. Maybe Tier-1 storage or a storage system with snapshot capabilities (and the configuration used). One example is a category called "Tier-1StorageSnapshotCapable" and a tag called "SnapshotHourly".

Ownership, QoS, Production Times: There are many additional capabilities you can implement with tags that can represent the services provided by the objects in the vSphere environment. This can include who "owns" the application, what service levels are expected or even document the maintenance windows of an application.

My goal is to give you a view of the capabilities of vSphere tags, and the "a-ha" moment may come where you realize there is an opportunity to do something new with tags that will make improve accuracy in the vSphere environment. When a tag is applied, it is easily visible on a VM like shown below:

Image

How do you use vSphere tags?

What use case do you have to make vSphere tags and categories part of your day-to-day administration? Would it make sense to have applications identified? What about building backup policies? In any way, self-documenting tags can make the task easier as VMs continue to grow. Share your vSphere tag and category use case by emailing us at wsn@mtit.com so other readers of our newsletter can benefit from your expertise and your experience using them.

 

 

Ask Our Readers - Question about flow control (new question)

Alain who manages IT in a mid-sized company in Strasbourg, France asks us:

Loved your story about 10gb networking, merci!! I have one question - why to disable flow-control on backbone switches?

In my understanding flow control was originally designed as a mechanism to prevent network devices like switches from having to deal with more packets than they can handle. This post on Cisco Blogs explains the concept:

http://www.wservernews.com/go/kqgrpbb8/

I've been told however that VoIP and flow control don't play nicely together, so on backbone networks I've heard it as a recommendation that flow control be disabled on switches. I don't know however if this is really best practice or not, so maybe some of our readers who are networking experts can weigh in with their own suggestions on this matter -- email me at wsn@mtit.com

 

 

Tip of the Week

Got any IT pro tips you'd like to share with other readers of our newsletter? Email us at wsn@mtit.com

This week's tip comes to us from Glenn Turner who is Manager End-User Services at an Australian company. 

How can I stop Edge from trying to open my PDFs?

Glenn says: In Windows 10 v.1709, I disabled Microsoft Edge via AppLocker in my environment and that was working quite well. We've decided that in v.1809 we would give people Edge. One thing I noticed after doing however is that when Edge is re-enabled and I double-click a PDF, I'm prompted with this:

Image


I pulled up the notes from the Premier case I logged a year or so ago about preventing Edge from stealing the associations, and tested their additional guidance: by adding these registry settings (in our case, by group policy preference), Edge no longer prompts with the above offer, and Acrobat just opens:

[HKEY_CURRENT_USER\Software\Classes\AppXd4nrz8ff68srnhf9t5a8sbjyar1cr723]

"NoOpenWith"=""

"NoStaticDefaultVerb"=""

Glenn also points us to the following articvle on Ghacks for background info on how one can find the AppXd4nrz8ff68srnhf9t5a8sbjyar1cr723 key in the first place:

And a few issues back we had an Ask Our Readers item that examined the difficulties that sometimes arise when trying to update Windows 10 machines when the system volume is too small, for example on laptops that have small SSDs. Somewhat along these lines a reader named Erich from Switzerland sent us the following comment:

I had problems updating some HP computers of my customers because the recovery partition was too small. One solution was to shrink the windows partition and then enlarge the recovery partition using a 3rd party partition editor from Aomei:

http://www.wservernews.com/go/nl4f29x7/

Another would be to delete the recovery partition, as it is not needed for the operation of windows. This would give some 15GB free for the operating system, which would be the better solution for Robert. 

And of course don't let your users sync their 256Gb I-Phones full of pictures and music with the computer!

I was a bit surprised by Erich's comment and responded by saying, "Erich did you mean shrink the *recovery* partition and then enlarge the *Windows* partition?" Erich replied:

Hi Mitch, No the other way round. The update failed because the *recovery* partition was too small. (It was the update from Windows 10 1703 to 1709) So I had to enlarge the recovery partition.

I responded, "Fascinating. Why would that happen? I thought the recovery partition was factory installed and remains unchanged when you upgrade Windows 10 versions…" and Erich replied:

Thats what I thought too. But it seems HP (or windows) saves some information in the recovery partition. HP saves the recovery image of windows plus oem drivers and software in this partition.

Anyway enlarging the partition did help.

Have any other readers got more insight into how this works? We'd love to know more--email me at wsn@mtit.com

 

Factoid - Sayonara, Geocities-san!

Last week's factoid and questionwas this:

Fact: New research from the University of Central Florida in Orlando suggest that the IAU decision in 2006 to demote Pluto from being called a planet was a mistake i.e. Pluto should still be called a planet!

Question: How do you think Plutonians are reacting to this news?

The best response we received for this question was this one from Doug who wor4ks in IT for a government agency in Iowa:

Answer: Cool and distant

And the runner-up response was from Murray who works in IT for the government of New York State:

Is this where we respond with the obligatory comments about it being a "Mickey Mouse planet" or a "dog-eat-dog world"??? Because if it is, I refuse to participate in such childishness ;-)

Now let's move on to this week's factoid:

Fact: GeoCities dies in March 2019, and with it a piece of internet history.

Source: http://www.wservernews.com/go/vo5phneu/

Question: And I bet you thought that Geocities was already dead, right? Anyways, my question is this: How many of you fondly remember browsing Geocities in its heyday? And did any of you newsletter readers actually own your own piece of Geocities by putting up a web page on some topic?
