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.

VMware Virtual SAN 6.0 (formally was v2.0) was a big improvement of the VMware’s hyperconverged storage solution with some important new features like the new filesystem (with powerful snapshot implementation), the concept of fault domain (to improve data resiliency), more scalability and the full flash option. Now VMware has announced a new release: Virtual SAN (or VSAN) 6.1, with new improvements, including enhanced usability & management, advanced troubleshooting, and several new features.

With the new VMware vSphere 6.0 suite there is also a new version of VMware Virtual SAN (or VSAN) now in version 6.0 (but formally it’s a 2.0 version). Seems still a separated products, althougt my hope is that it may included in some vSphere bundle (like was with the VSA). This new version brings a lot of new features and now it’s ready also the business critical applications (version 1.0 was more targeded for ROBO, VDI, DR, testing, … scenarios).

NexentaConnect is a complete suite of software solutions to combine software-defined storage with cloud, enterprise, and desktop deployments. Providing acceleration, automation and analytics that can only be delivered when storage is integrated with the entire solution stack. There are different type of Connect, and recently has been announced a specific version of VSAN: NexentaConnect complements VMware Virtual SAN simplified operating and storage consumption models by providing several new features:

VMware Virtual SAN (or VSAN) is a Software Defined Storage solution from VMware that also fits in the hyper(visor)-converged model. Although is a separate product, the core functions to implement it are already present in the vSphere 5.5 U1 version making really easy to deploy and enable it. Also the HCL is mainly the same from vSphere 5.5, but some requirements and special considerations must be considered before implementing a VSAN solution. You can start from the scracth buy scratch your hyper-converged architecture, or you can directly bought a Virtual SAN ready nodes (minimum 3 […]

Atlantis Computing has announced a new product: Atlantis ILIO for Virtual SAN, that mainly combined Atlantis ILIO with VMware Virtual SAN and VMware Horizon 6 with the declared intention to build a ultimate hyper-converged platform for VDI. Atlantis ILIO will insert a transparent software layer between the virtual machine and the underlying storage infrastructure. The joint solution leverages pooled local solid state drives (SSDs) and hard disks (HDDs) created by VSAN with Atlantis ILIO to optimize the resultant storage pool improving storage performance and increasing the available storage capacity provided to the application.
