Virtual SAN Backup with VDP – New White Paper

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).vsan_vdp_white_paper 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!

Operationalizing VMware Virtual SAN: How to configure alarms

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?

Oregon State University uses VMware Virtual SAN for their growing VDI environment

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.

VMware Virtual SAN Performance Testing – Part IV

Virtual SAN ObserverIn 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.

VMware Virtual SAN Performance Testing – Part III

Virtual SAN ObserverIn 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

VMware Virtual SAN Performance Testing – Part II

Virtual SAN ObserverIn 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.

Myth versus Math: Setting the Record Straight on Virtual SAN

By Jim Armstrong

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.

VMware Virtual SAN: Storage for the Software-Defined Data Center

VMware Virtual SAN delivers storage that’s as nimble as a VM. It’s a key part of VMware’s Software-Defined Data Center initiative and helps enterprises realize the benefits of virtualization for storage. Virtual SAN abstracts and pools server side disk and flash to deliver high-performance, agile storage for virtual environments. Virtual SAN does for storage what vSphere did for compute.

At VMware, innovation is a constant – and Virtual SAN is a product of that innovation. It’s being viewed as an industry “game-changer” that can redefine how enterprises buy storage. As part of the VMware vision for Software Defined Storage, Virtual SAN offers customers a new storage solution, one that’s purpose built for the agile, dynamic vSphere environments our customers depend upon.

Listen to Gaetan Castelein, VMware’s Sr. Director of Storage and Availability, explain the benefits of VMware Virtual SAN.

We’re excited to share our radically simple shared storage solution with you. To learn more about how VMware Virtual SAN can increase your IT agility, visit our Virtual SAN homepage, our VMware Virtual SAN blog, and follow our @vmwarevsan handle on Twitter.
