Maintenance Mode within vSAN

Before building out your vSAN cluster, one thing that you should be conscious of is that of maintenance activities. Some time ago, someone told me “Anyone can make something work, but few take the time to think of the long term implications (years from now) of setting things up a certain way”.

How to: Creating VM Storage Policies in vSAN

Introduction to VM Storage Policies 

One of the great features within vCenter is the ability to create VM Storage Policies. What are VM Storage Policies?

According to VMware Official documentation, VM Storage policies are specific requirements placed upon underlying storage to ensure desired characteristics are met.

How to: Enabling Deduplication and Compression in vSAN

One of the most powerful technologies today in Storage is a feature called Deduplication. Deduplication is technology that references data once instead of multiple times. This allows for insane Data Reduction. For instance, if you had 600GB of data with a 6:1 Dedup ratio, only 100GB would actually be stored! Dedupe within vSAN is done on 4KB Block level.

How to: Claiming Disk for vSAN

On Monday’s post, I did a quick blog on how easy it was to enable vSAN within vCenter. vSAN, as it was discussed in earlier posts,  is a very powerful tool that utilizes software defined storage at the hypervisor level, which reduces costs and complexity. Storage is the key ingredient to this solution, so we may need to add disk in order to actually utilize vSAN right?  Fortunately, VMware (like most things with vSAN) has made this process incredibly simple. Today’s blog is a continuation from Monday’s blog, which will show us how easy it is to claim disk for vSAN usage. Disk claiming is needed in order build out your vSAN datastore. This is what makes vSAN so different from traditional hosts/storage configurations.

How to: Enabling vSAN

Last week I wrote a detailed post last week on vSAN. Now that vSAN has been explained and the benefits understood, let’s get started with how to enable it within a lab setting.

Note: This is a quick blog on how to enable vSAN, which will be part of a larger mini series that will take us through each step.  It’s primary purpose is to show how easy it is to enable vSAN. With that said, vSAN shouldn’t be enabled within a production environment without proper planning, consideration, and change controls. While vSAN is something you can enable with the “flip of a switch”, it doesn’t mean you should. Careful consideration should be taken while planning. Performance is something else that you should keep in mind. If all possible, engage the help of a vSAN resource that can guide you through the process. This isn’t something to be taken lightly, and caution should be taken when designing your vSAN deployment. Finally, the VMware Hardware Compatibility Guide should always be used.

Additional information specific to vSAN HCL can be found by click this link.

Without referencing this, you can quickly set yourself up for failure. With that said, always reference the compatibility guide religiously!

vSAN: What is it? How is it different?

Today’s blog post is all about vSAN. vSAN, according to VMware, is VMware’s hyper-converged software solution.  In order to understand the differences between hyper-converged and software defined, let’s look at the definition for each. With all of the cool/hip buzz words, there is a lot of misunderstandings, and often times these words are interchangeably used without understanding the terminology correctly.

How to: Dell EMC Data Domain Virtual Edition Install on ESXi

Finalizing this month’s series on data protection, I wanted to follow up last week’s blog post on installing Avamar Virtual Edition with this one, which is installing Data Domain Virtual Edition. The two are often married together in Data Protection deployments. Simply put, Avamar is the front end backup engine that has all of backup software, and DataDomain is the landing spot for the backup data.  DataDomain is Dell EMC’s appliance based deduplication device. It is the market leader in purpose-built backup appliances.  Various workloads can be ingested, including data from Avamar, VEEAM, Networker, etc. Like the Avamar VE, DataDomain VE allows you fully take advantage of virtualization in one easy to manage package. The virtual edition is geared towards small-to-medium size environments and/or EDGE locations (ROBO).  With that said, let’s get started!

 

Be sure to check out the system requirements before you proceed.
