One of the biggest advantages of Virtual SAN is that it is so easy to set up and use. Out of all the evaluation options available to them, many customers have realized that trying it out in their own environment is entirely feasible.
We’ve been keeping track of the many Virtual SAN evaluations to date, and have created a quick guide that should help anyone evaluating Virtual SAN in their environment. In it, you’ll find a checklist on configurations, verifying compatibility, testing the network, expected behaviors for failure testing, and tips on testing performance. It’s an essential guide for anyone working with Virtual SAN.
We hope you find this document useful!

Hot off of the press: A new white paper that discusses backing up virtual machines running on VMware Virtual SAN (VSAN) using VMware vSphere Data Protection (VDP). These are the main topics that are covered:
- VDP Architectural Overview
- Virtual SAN Backup using VDP
- Factors Affecting Backup Performance
The paper details test scenarios, how backup transport modes affect CPU and memory utilization of the VDP virtual appliance, and how the vSphere hosts management network is impacted when the Network Block Device over Secure Sockets Layer (NBDSSL) transport mode is utilized. The paper concludes with a summary of observations, recommendations when deploying the VDP virtual appliance to a Virtual SAN datastore, and some discussion around transport modes and running concurrent backups. A special thank you goes to Weiguo He for compiling this data and writing this paper!

VMware Virtual SAN has received amazing response from the virtualization community. Now as more and more customers are completing the acquisition and implementation processes, we are receiving more requests for operational guidance. Day 2 operations is perhaps my favorite topic to explore. Essentially the questions asked can be summed up as “Ok, I have done the research, proved the concept, and now have this great new product. Help me know the recommended practices to monitor, manage, and troubleshoot the inevitable issues that pop up with any software”. This question is the driver behind our new blog series, “Operationalizing VMware Virtual SAN“.
In this series, our aim is to take your most frequently asked questions around Virtual SAN Operations and provide detailed recommendations and guidance. In our first article in this series we look to answer the question “How do I configure vCenter Alarms for Virtual SAN?”

Get your notepads and pens ready, because we’re co-hosting a webinar with Nexenta, on November 19, at 8 a.m. PST detailing our complete, software-defined, hyper-convergence infrastructure offering. Join this webinar to learn how Virtual SAN and file services will fit in your environment, what Software-Defined Storage has to offer your organization and how your business can benefit.
VMware’s own Rawlinson Rivera, Senior Technical Marketing Architect, will co-host the webinar with Nexenta’s Michael Letschin, Director, Product Management, Solutions. During this webinar, we’ll discuss:
- Storage provisioning and management of VMware Virtual SAN’s hypervisor-converged storage
- Merging VMware Virtual SAN with VMware EVO: RAIL into a hyper-converged infrastructure that combines compute, networking and storage resources
- How NexentaConnect for VMware Virtual SAN enables better file services, snapshot and self-service file recovery
- How Nexenta can support a variety of workloads and business-critical situations through its Software-Defined Storage solutions
Register for this webinar and learn how to build on your VMware Virtual SAN instance with Nexenta!

Oregon State University, a public institution with more than 26,000 students and growing VDI workloads wanted a high performance storage tier for their VDI environment. However, they wanted the solution to be up and running before the school summer session began, along with being easy to operate and scale on an on-going basis, without requiring large upfront investments.
In Part I, Part II and Part III of this blog post series, we reviewed methods of running benchmark tests on a Virtual SAN cluster using three different methods; synthetic I/O Tools such is Iometer, pre-created application I/O trace replay files available for download, or custom created application I/O trace replay. Once you are running benchmark testing, there will be the need to assess and analyze the performance results of your Virtual SAN cluster, and how they meet the needs of the target applications within your environment . In this post, we will review some key concepts in performing a performance analysis of your Virtual SAN solution.
In the previous VMware Virtual SAN Performance Testing blog post we reviewed the benefits of running performance tests utilizing I/O trace files over synthetic workload tools such as IOmeter to more accurately characterize the performance of a Virtual SAN cluster. The VMware I/O Analyzer includes pre-created trace files of specific application profiles that allows you to quickly perform scale-out testing utilizing a mix of industry standard workloads But what if you want to characterize the performance of your existing vSphere virtualized environment within a new Virtual SAN configuration? This is were the use of custom I/O Trace replays can be useful. Continue reading
In the first installment of the Virtual SAN Performance Testing series, we reviewed benchmarking performance using synthetic I/O generation tool Iometer, automated by the VMware I/O Analyzer appliance. Using Iometer, or other synthetic I/O generation tools is frequently the first option for benchmarking selected, as it is an operationally light weight method to benchmark storage performance. But what if you want to be able to simulate real world workloads within your Virtual SAN cluster, without the burden of building out applications. That is where I/O trace files can come into play.

It seems hard to believe to me but it was just six short months ago that we officially launched our Virtual SAN product. I spent the months leading up to the launch and the months since learning about Virtual SAN and the storage market at large and since our launch I have watched as others shared their opinions of our product. By now, I have seen some common areas where people make key mistakes about how Virtual SAN works. What I’d like to do is discuss some common misconceptions about Virtual SAN and hopefully along the way help folks understand what sets Virtual SAN apart from other seemingly similar technologies.
