Avec Virtual SAN, VMware parachève avec succès sa stratégie Software Defined Data Center (SDDC). Selon VMware, parce qu'il est centré sur la machine virtuelle et qu'il permet d'appliquer automatiquement des politiques, son logiciel Virtual SAN (Storage Area Network) inaugure une nouvelle ère dans le provisionnement du stockage. Généralement, les réseaux de stockage SAN sont composés d'éléments disparates mis en commun pour former un pool dans lequel on peut venir puiser des ressources. En général, les SAN sont aussi constitués... [Lire la suite]

HP on software-defined storage: why VSA is the future   In my last post, I posed a question: How do you define software-defined storage? I offered up a base definition of what software-defined storage means to HP. Since then IDC has released a new taxonomy on software-defined storage which includes this definition:   IDC defines software-based storage as any storage software stack that can be installed on any commodity resources (x86 hardware, hypervisors, or cloud) and/or off-the-shelf computing hardware...

I was reading this article on the HP blog about the future of Software Defined Storage and how the VSA fits perfectly. Although I agree that a VSA (virtual storage appliance) could potentially be a Software Defined Storage solution I do not really agree with IDC quote used for the basis of this article and on top of that I think some crucial factors are left out. Lets start with the IDC quote: IDC defines software-based storage as any storage software stack that can be installed on any commodity resources (x86 hardware,... [Lire la suite]

After fielding a number of questions around this topic recently, its come to my attention that there is a misunderstanding on how to implement the vSphere Storage Appliance (VSA) for certain ROBO solutions. The requirement around the tie-breaker code (VSA Cluster Service) is either misunderstood or misinterpreted when it comes to 2 node VSA deployments at remote office/branch office (ROBO) sites. Let’s be clear about it now – the VSA needs 3 votes in order to function correctly as a cluster. In a 3 node VSA deployment, this is not an... [Lire la suite]

For those of you considering the vSphere Storage Appliance as a shared storage solution, I bring you a piece of very good news. The RAID10 configuration requirement on the hosts has now been relaxed. As of today, VMware will now support RAID5 & RAID6 configurations alongside the original RAID10 configuration. This will mean that even more local storage can now be utilized as shared storage (NFS datastores). This is a common feature  request that we heard from a lot of potential VSA customers, so I'm glad we've been... [Lire la suite]
