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 cloud hybride, en particulier, nécessitent que l’heure des systèmes locaux soient correcte vis-à-vis des systèmes dans le... [Lire la suite]

On a previous post, I’ve write on how build custom ESXi ISO with 3rd part tools. Those tools are not mentioned by VMware so probably are not supported. But you need a custom ISO in order to install ESXi on a host where the network drivers are missing (storage could be not an issue if you install it on a USB/Flash card). The other solutions are use a vendor related custom ISO or the embedded version that probably already include the right drivers. But in order to build your custom ISO you could use the same...

If you're using Linux 2.6 kernel-based virtual machines and you're experiencing slow storage performance as compared to physical hosts, the might be a problem with the I/O Scheduler. As of the Linux 2.6 kernel, the default I/O Scheduler is Completely Fair Queuing (CFQ). The default scheduler will affect all disk I/O for VMDK and RDM-based virtual storage solutions. In virtualized environments, it is often not beneficial to schedule I/O at both the host and guest layers. --> The rest is on the blog... [Lire la suite]

This week I installed a fresh vSphere 5.1 Update 1 environment and I wanted to configure it will real world certificates to get rid of all those “Do you really really reeeeeally accept this insecure website” messages. Using the VMware SSL Certificate Automation Tool I generated all the new certificates and then started changing the certificate on the VMware SSO server. When doing this, you’ll be asked for the Master password. Since I learned a while ago in a very painful way that the Admin@System-domain password is not equal to... [Lire la suite]

My ESXTOP page is still one of the most visited pages I have, it actually comes in on a second spot just right after the HA Deepdive. Every once in a while I revise the page and this week it was time to add VisualEsxtop to the list of tools people should use. I figured I would write a regular blog post first and roll it up in to the page at the same time. So what is VisualEsxtop? VisualEsxtop is an enhanced version of resxtop and esxtop. VisualEsxtop can connect to VMware vCenter Server or ESX hosts, and display ESX server stats... [Lire la suite]

What is VMware Virsto and What Does it Do? Since VMware’s acquisition of Virsto earlier this year, many customers and folks in the community have expressed a great deal of interest in the product. Since so many folks have requested more information about the product, I’ve decide to write a series of in-depth blog articles that will discuss VMware Virsto’s capabilities, benefits, and targeted use cases for the product. VMware Virsto is a software-defined storage solution design to optimize the use of external block storage in vSphere... [Lire la suite]

A commonly requested thing that people ask for from vSphere Replication is more consolidated reporting.  You can set alerts in vCenter to key off of various things that surface from vSphere Replication, but it is not exactly a consolidated list when doing so.  What people are looking for is a common interface to pull together *just* vSphere Replication alerts for things like RPO violations. My good friends and colleagues Alan Renouf and Lee Dilworth have identified a really elegant way to pull this... [Lire la suite]

“I hear and I forget, I see and remember, I do and I understand.”  This Confucian proverb may hold an important key in addressing today’s IT skills gap. According to the 2013 Gartner CIO Agenda Report, of the 2,053 CIOs surveyed, more than half reported shortages in talent relating to key digital technology skills, including enterprise architecture, business intelligence and analytics, security and risk management, and IT strategy and planning. I’ve talked before about the importance of continued education for IT... [Lire la suite]

In one of my recent VDI projects I was working with Symantec Endpoint Protection as the choice of AV solution. When I started working on the project I was not able to find much information on the exact steps required for me to design and implement a Horizon View solution with Symantec Endpoint protection. I worked my way across the design and implementation by reading various whitepapers both by VMware and Symantec. This prompted me to work on a series of blog articles which covers the Symantec SEP integration with... [Lire la suite]
