How to create shared iSCSI storage for ESXi using StarWind’s iSCSI SAN Software

How to create shared iSCSI storage for ESXi using StarWind’s iSCSI SAN Software In my previous post, I mentioned that I use StarWind Software’s iSCSI SAN software to provide iSCSI LUNs for my home lab.  In this post, I’ll document the process to create a simple shared iSCSI LUN setup.  Using that, one can provide as many LUNs as required to an ESXi setup, possibly with multipathing – very useful if one doesn’t have expensive network storage and virtual appliances don’t seen flexible enough.  I should apologise in...

How is Horizon View configured for VMware VSAN?

In my previous article I discussed VSAN benefits for Horizon View (How does VMware VSAN help Horizon View?), including CAPEX and OPEX savings provided by the use of inexpensive server disks for shared storage and simplified day-to-day storage configuration and provisioning activities. In this article I will explore some of the VSAN capabilities and features and how they relate to Horizon View. --> Please see the rest on the blog : http://myvirtualcloud.net/?p=5440

Bulk Registering Virtual Machines with PowerShell

I recently rebuilt a Hyper-V server – where all of my virtual machines were shutdown first and stored on a secondary disk.  Once I had finished installing the operating system and had Hyper-V up and running – I wondered what the most efficient way to get the virtual machines all reconnected would be.  I ended up using PowerShell to do a bulk import; however this did involve a bit of experimentation to get right. The first thing I had to deal with was the fact that our “import-VM” command requires that you provide a .XML... [Lire la suite]

Synchronisation des horloges dans un environnement virtualisé

Voici une question qui se pose régulièrement chez les clients, et voici un avis intéressant sur la question....   Dans un environnement de domaine Windows, la synchronisation des horloges des différents systèmes est primordiale, notamment pour que le protocole d’authentification Kerberos fonctionne. Il y a d’autres effets de bord sur certaines applications qui peuvent donner des erreurs difficiles à diagnostiquer si des systèmes ne sont pas synchronisés entre eux, ou ne sont pas à l’heure exacte. Les environnements de type... [Lire la suite]

Frequently asked questions about Virtual SAN / VSAN

After I published the vSphere Flash Read Cache FAQ many asked if I would also do a blog post for frequently asked questions about Virtual SAN / VSAN. I guess it makes sense considering Virtual SAN / VSAN being such a hot topic. So here are the questions I have received so far, followed by the answers of course. If you have a question do not hesitate to leave a comment. Make sure to visit the VSAN community forum and sign up for the beta! VSAN requires an SSD, what is it used for? The SSD is used for read caching (70%) and write... [Lire la suite]
