If you are using Veeam Backup & Replication with a VMware vSAN datastore you are probably following the Veeam KB 2273 (Configuration for VMware VSAN). But this guide is only limit to recommend the hot-add transport mode. So you are going to create several Veeam proxies because Veeam Backup & Replication chooses the most appropriate backup proxy to reduce the backup traffic on the VSAN cluster network. Maybe also one per host.

The vExpert vSAN program is a specific VMware vExpert (sub)programs focused on the vSAN product. The idea to have specialized groups of vExpert was to bring again (like at the origins) the vExpert program as an “elite” program. After the vExpert vSAN 2016 and 2017 lists, now VMware has just announced the vExpert vSAN 2018 new list. I was honored to part of this list again, and that’s pretty exciting, considering that I’m there from the first list.

Just one year ago, VMware has announced vSAN 6.6… now it’s the turn of vSAN 6.7, contextually of the release of vSphere 6.7 GA. VMware vSAN is the VMware’s Software Defined Storage (SDS) solution that also fits in the hyper(visor)-converged model to build a simple (to be managed) and scalable HCI solution. Although is a separate product, the core functions to implement it are already present in the vSphere versions making really easy to deploy and enable it.

VMware vSAN should manage better VM snapshots compared with traditional storage and VMFS datastores. The reason is the new (v2) on-disk format in VSAN 6.0 and the new filesystem that is used: VirstoFS. VirstoFS is the first implementation of technology that was acquired when VMware bought a company called Virsto a number of years ago. Also there is a new sparse format called vsanSparse. These replace the traditional vmfsSparse format (redo logs).

VMware vSAN provides both enterprise-class scale and performance supporting a wide variety of use cases and businesses of all types and sizes. One of the popular use cases for VMware vSAN is running Business-Critical Applications (BCA). But in this case it’s not only running some workload in a virtual environment, but it’s also provide reference architecture, proven configurations and also the ability to use specific functions, like guest clustering.

One year ago, VMware has started new vExpert (sub)programs on different technologies. One was the vExpert vSAN. I was honored to part of the first list. Now the list for 2017 vExperts who received the vSAN award has been published. The program is build upon the vExpert program. To apply you must be a current vExpert as well as evangelizing VMware Virtual SAN. There will be an application once per year for each of the sub-programs.

The new VMware Virtual SAN (or vSAN) 6.6 adds several enchaments and new features as described in the announce notes. Some interesting news are related to security aspects and how data-at-rest could be protected: one option could be new vSphere 6.5 VM encryption format but now it’s also possible use the native vSAN encryption. Duncan’s post explains the difference of those two approaches.

The new VMware Virtual SAN (or vSAN) 6.6 adds several enchaments and new features as described in the announce notes. Most of those aspects are related to data and cluster resiliency (as expected by a storage solution), including:

On the second half of 2016, VMware has started new vExpert (sub)programs on different technologies. One was the vExpert VSAN. And finally the list of 2016 vExperts who received the VSAN award has been published. The program is build upon the vExpert program. To apply you must be a current vExpert as well as evangelizing VMware Virtual SAN. There will be an application once per year for each of the sub-programs. Applications for 2017 will open around February of 2017.

As announced some months ago, the new Virtual SAN (VSAN 6.2) will add new data services making this solution more rich that before. Version 6.1 was announced during the last VMworld editions with some interesting features, including a ROBO scenario. But was still limited in data service: better snapshot technologies, better VMFS, but still some limits and no deduplication, no compression, no erasure coding at all.

VMware Virtual SAN (VSAN) 6.1 was announced during the VMworld US 2015 with some new interesting features. Now it’s finally available on VMware vSphere download page. Considering that it’s implemented at hypervisor level, there isn’t a specific download: you have to upgrade (or download) vSphere 6.0 Update 1. VMware Virtual SAN 6.1 increases data protection options for business-critical environments with the new Stretched Cluster feature providing zero-point Recovery Point Objective (RPO) and enhanced VMware vSphere Replication. Additionally, VMware Virtual SAN 6.1 enables new advanced management and monitoring through deep integration with VMware vRealize Operations and […]

The new Virtual SAN 6.1 has also another new features related to a specific deployment scenario: a 2-Node Remote Office Branch Office (ROBO) configuration. This configuration was possible with the previous VMware product (VSA) but was not suitable with VSAN, making space for other solutions like StorMagic SvSAN or StarWind Virtual SAN.
