ALERT: Login issue after updating to vCenter 5.1 Update 1

VMware has become aware of an issue that may occur after upgrading to vCenter Server 5.1 Update 1.   Specifically: You are unable to log in using the vSphere Web Client or domain username/password credentials via the vSphere Client. This issue can occur if the specified vCenter Server login domain user account is associated with a large number of domain groups and multiple domains are configured as SSO identity sources. The precise number of groups at which this issue can occur varies due to the nature of Active... [Lire la suite]

Petite Réflexion personnelle : Pourquoi VMware plutôt qu'Hyper-V (même "gratuit"!)

Lorsque des clients me demandent de justifier le coût de VMware comme hyperviseur, par rapport à Hyper-V qu'ils considèrent comme "gratuit", voici de quoi leur expliquer le coût de la gratuité :   http://social.technet.microsoft.com/wiki/contents/articles/1349.hyper-v-update-list-for-windows-server-2008-r2.aspx   Ceci est la liste des patchs/hotfix à intégrer sur un hôte Hyper-V en cluster ou non afin de s'assurer de son bon fonctionnement. En effet Windows Update/Microsoft Update ne suffit pas à avoir un hôte Hyper-V... [Lire la suite]

How to install integration services when the virtual machine is not running

We’ve been talking to a lot of people about deploying integration services (integration components) lately.  As it turns out, they’re pretty easy to patch offline with existing Hyper-V tools. First, why would you update integration services on a not-running (offline) VM? Offline VM servicing is valuable for VM templates places that create new VMs frequently since it allows you to keep VM templates up-to-date.  While this post targets exclusively integration service updates, the same update approach applies to many updates...

Updates for Hyper-V

A new article has appeared on the TechNet Wiki that provides a complete list of updates for Hyper-V on Windows Server 2012: http://social.technet.microsoft.com/wiki/contents/articles/15576.hyper-v-update-list-for-windows-server-2012.aspx I am really happy to see this online, as we have received lots of positive feedback about how useful the existing documentation is for updates that are available for Hyper-V on Windows Server 2008 R2 and on Windows Server 2008.  Hopefully this will help everyone in planning and managing their...

Hyper-V Replica Certificate Based Authentication - makecert

We have had a number of queries on how to enable replication using certificates created from makecert. Though the Understanding and Troubleshooting guide for Hyper-V Replica discusses this aspect, I am posting a separate article on this. The below steps are applicable for a simple lab deployment consisting of two standalone servers – PrimaryServer.domain.com and ReplicaServer.domain.com. This can be easily extended to clustered deployments with the Hyper-V Replica Broker. Makecert is a certificate creation tool which generates... [Lire la suite]

Q and A: I only have two NICs on my Hyper-V host. Should I team them or not?

Question via e-mail: I am using blade servers for my Hyper-V cluster and I can only have two NICs per blade in this configuration. I am considering two options on how to configure the NICs: 1)      Use one NIC for internal network and one NIC for external network, connected to the virtual switch2)      Team the two NICs together and use the same path for all kinds of traffic What would you recommend? Answer If you're using clusters, I assume you're concerned with high... [Lire la suite]

RE: Is VSA the future of Software Defined Storage? (OpenIO)

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]
