Is VDI causing you gray hairs? Virtual SAN and Horizon can help!

Our 2,000+ Virtual SAN customers are deploying VMware hyper-converged systems for all kinds of solutions—from supporting large Oracle databases to powering remote IT rooms to simplifying test/dev environments—but one specific workloads is always among the most popular use cases for VSAN: virtual desktops (VDI).

The struggle to find both high performance and affordable IT infrastructure, especially storage, for VDI is real. A storage system may look great on paper or even in a small POC (proof-of-concept), but hit that N+1 user with a traditional storage system and the productivity of all N+1 users can come to a grinding halt. You are then faced with an expensive, second storage purchase or left to troubleshoot and revisit all your sizing and performance assumptions: task or knowledge workers, virus scan timing, desktop recompose frequency, number/type of drives, etc…

There’s an easier way! VMware’s hyper-converged infrastructure, built on Virtual SAN and vSphere, uniquely addresses the storage challenges that have historically plagued the VDI world. Virtual SAN offers the simplicity, performance and cost needed for successful VDI deployments—both today and as your business scales. Take a look at the following video to learn why Virtual SAN is a great fit for Horizon customers deploying VDI.

Want more details on deploying VSAN and Horizon? Read the latest VMware Horizon and Virtual SAN all-flash reference architecture. For those attending VMworld 2015 next week, you can learn more about Horizon and the Software-Defined Data Center in “Unleashing the Power of SDDC to Accelerate Desktop Transformation” (Session ID: EUC5438).

And remember, if you are a Horizon customer, then you may have Virtual SAN already for free through your Horizon licenses. Give it a try today and save yourself from having to learn and purchase another storage solution (if you know vCenter then you know Virtual SAN)!

You can test-drive VSAN today with a free, online Hands-On Lab (no installation required). If you already have access to a virtualized server, get started by downloading a free Virtual SAN evaluation.

Support for non-uniform/heterogeneous VSAN clusters? Yes!

Over the last couple of weeks I’ve been asked this question by various field people and potential customers: does VMware support non-uniform / heterogeneous VSAN clusters? The question typically comes during the pre-sales stage and by the sounds of it is one of those myths that competitors use to give their product the edge in a bake-off.

For those who just care about the facts I can be short: Yes we support non-uniform / heterogeneous VSAN clusters. Our very first datasheet has the following statement in it:

Hardware independence – Virtual SAN can be deployed on hardware from any server manufacturer. This gives you the flexibility to build out customized storage systems in heterogeneous hardware environments.

Anyone telling you VMware VSAN does not support non-uniform / heterogenous environments is badly informed, or not being honest. Some of you may say, hold on… I’ve seen posts where people are making a recommendation for uniform clusters. A strong recommendation even in some cases, does that mean VSAN doesn’t function properly when you use a non-uniform cluster? Again, I can be short: No it does not. But why did they make this recommendation?

The reason is simple: lower operational complexity. Just like with vSphere HA and vSphere DRS, balancing resources and doing calculations to see if your cluster has sufficient spare resources to reprotect VMs after a failure is easier when you have a uniform cluster. Not that it is rocket science when the cluster is non-uniform, as you will just need to assume that if something fails it will be the host providing the most storage capacity. Luckily with VSAN the whole cluster acts as “rebuild capacity”, which means that mitigating this risk is relatively easy.

As an architect I usually prefer to avoid risks though, but also understand that situations like these occur and there is no reason to fear them. I spoke with a customer who is managing a rather large non-uniform environment last week. They started with 1U hosts, but for various reasons decided to go with 2U hosts more recently. Using the same cache to capacity ratio per host they’ve had no challenges whatsoever in this environment (they even went with more cache as SSD prices lowered). Performance and management has been a breeze, they are very keen on standardization but the ability to be flexible when needed is actually what they love about VSAN.

Virtual SAN going offshore

Over the last couple of months I have been talking to many Virtual SAN customers. After having spoken to so many customers and having heard many special use cases and configurations I’m not easily impressed. I must say that half way during the conversation with Steffan Hafnor Røstvig from TeleComputing I was seriously impressed. Before we get to that lets first look at the background of Steffan Hafnor Røstvig and TeleComputing.

TeleComputing is one of the oldest service providers in Norway. They started out as an ASP with a lot of Citrix expertise. In the last years they’ve evolved more to being a service provider rather than an application provider. Telecomputing’s customer base consists of more than 800 companies and in excess of 80,000 IT users. Customers are typically between 200-2000 employees, so significant companies. In the Stavanger region a significant portion of the customer base is in the oil business or delivering services to the Oil business. Besides managed services, TeleComputing also has their own datacenter they manage and host services in for customers.

Helping IT Professionals Make Informed Choices Around Storage

Recently, on the Virtual Blocks blog, we’ve discussed how VMware Virtual SAN stacks up in some head-to-head performance tests. The results, intriguing as they were, caught the eye of some and generated some great conversation.

Let’s bring you up to speed:

  • Chuck Hollis then followed up these initial impressions with a second blog post, “VSAN vs Nutanix Head-to-Head Performance Testing — Part 2,” where transparency became key to backing data findings. With the VMware Virtual SAN competitor’s refusal to allow any side-by-side comparison of their product for publication. That reaction increased interest around the Virtual SAN-only data results.
  • In Part 3 of the blog series, Hollis explored the comparisons as to how VMware Virtual SAN stacked up against the competition in terms of relative cost and performance. This piece demonstrated that VSAN accomplishes more with less money.

The results from this performance testing got the IT community talking.

For example, CRN, broke down Hollis’ comparison in “6 More Reasons Why VMware Thinks Its Hyper-Converged Tech Beats Nutanix.The Register, too, published their own side-by-side comparisons of the data findings in, “A testing time for storage – it’s VMware from Nutanix, by a nose.“

“When software is decoupled from hardware, customers win,” said Hollis.

We encourage all customers to make informed choices around storage.

What makes VSAN so fast? How does VSAN protect my data? Chuck Hollis discusses a list of interesting questions the Virtual SAN team encounters most often, along with answers for each question. You don’t want to miss this one.

Virtual Volumes: VM-centricity And Why Its Important

With VM-centricity, Virtual Volumes eliminates a costly tradeoff that our customers have faced with traditional storage for years. Juan Novella discusses the concept and importance of VM-centricity.

VAAI Licensing Now Aligned with Virtual Volumes (VVol)

We believe the right way to manage storage is through VM-centric, policy-based management. When it comes to environments with traditional SAN and NAS storage, Virtual Volumes is the way to go. One necessary feature to enable a successful Virtual Volumes implementation is vSphere APIs for Array Integration (VAAI). Mauricio Barra talks about this and more in his blog.
