By now, you’ve probably heard about VMware Virtual SAN – the industry leader in hyper-converged software defined storage for virtual environments. You’ve probably also heard how VMware Virtual SAN can lower TCO by up to 50%, or how it is the first policy-driven storage product designed for vSphere environments that simplifies and streamlines storage provisioning and management.
But in case you haven’t heard, we’d like to invite you to #VSANchat – our inaugural Twitter chat, where our experts and the larger Storage community will be discussing how to get started with Virtual SAN and things to consider. On December 2nd, 2014, at 11am PT, we invite you to discuss tips, best practices and insight on everything VMware Virtual SAN.
Enabling Virtual SAN, if the environment is configured and ready, is an easy click of the mouse. If the environment is not ready however, the task of troubleshooting a new product, can easily become quite daunting. As we track the issues that have arisen during Virtual SAN deployments, we see that the majority of issues are common from deployment to deployment. The great news here is that these common issues can readily be identified and resolved. The real challenge is getting the information and guidance out into the hands of those who need it, before they actually have need of it.
It is for this purpose I introduce you to, the Virtual SAN 5.5 Validation Guide. This guide began as an internal collection of the most common Virtual SAN deployment troubleshooting scenarios. After receiving a number of requests from our customers, we have decided to publish this guide publicly as well.
The Virtual SAN 5.5 Validation Guide is a collection of common gotchas and recommended practices in spreadsheet form for easy reference and checkoff during the deployment process. There are two sections to this guide, the first section contains validation steps for common issues that can occur during the install process. The second section contains validation steps potentially required during post-install activities. Where possible, it contains both manual steps (vCenter Web Client actions) and CLI steps (RVC, ESXCLI, PowerCLI). These CLI steps can readily be translated into script form for easy automation.
When deploying Hadoop on vSphere, an important choice to make is the storage architecture for your data. There are several approaches to addressing this subject. We explore two important and contrasting approaches in this blog in order to help Hadoop architects understand their choices better. The different storage approaches described here are the direct-attached storage (DAS) one and the network-attached storage (NAS) style. We will see that these two can be combined together also to produce an elegant design for managing the different forms of data that appear in Hadoop/Big Data applications. Continue reading →
Virtual Machines much like physical ones require storage. Storage, on all its forms, is exponentially growing in recent years – almost doubling every other year. With the explosion of storage demands, IT managers are challenged to deliver the same service levels to virtual environments as they do with physical ones.
VMware Virtual SAN uses a unique Storage Policy Based Management (SPBM) platform that helps streamline the storage operations and allow for per-VM granular management. Due to this unique property that helps deliver an exceptionally simple storage solution, along with enterprise class performance , VMware Virtual SAN won in its first quarter of availability over 300 customers and 3 different awards.

As Virtual SAN continues to gain adoption within the industry, VMware is partnering with technology partners to develop and expand Virtual SAN solution guidance on differing platforms. A couple of key Virtual SAN whitepapers have been developed in conjunction with our flash vendor partners Fusion-io and SanDisk.

Starting April 18, IBM has included the Virtual SAN SKU on their OEM price book. Now IBM’s Worldwide Sales (field and channel partners) has the ability to resell Virtual SAN through IBM’s ordering system.
So by now most of you are aware that Virtual SAN 5.5 was released last week, and it came in with a bang. During the launch event, we announced some impressive performance numbers, detailing 2 Million IOPS achieved in a 32-node Virtual SAN cluster. One of the most frequent questions since the launch has been what are the details of the configuration we used to achieve this monumental task. Well wait no longer, this is the post that will reveal the details in all their magnificent glory! Continue reading →
VMware is excited to collaborate with Fusion-io, a leader in flash solutions with deployments by more than 6,000 customers, to provide customers a range of 15 enterprise-class PCI-E SSDs certified for Virtual SAN™ (see the VSAN Compatibility Guide). Virtual SAN™ leverages the speed and power of server-side flash to deliver a high-performance cache in front of direct-attached disks to provide scalable and cost-effective shared storage solutions.
