Step-by-Step: Deploy vCenter Server Appliance (VCSA) 6.5 - Le manuel du parfait plombier des snapshots VMWare (maj) Best Practices running VMware with NFS. There are several ways to store your Virtual Machines that run on your VMware Cloud Backend storage. You can store them locally on internal storage or on direct attached storage (DAS). Another way is to tie your ESXi servers to a central backend storage network, with protocols like FC and iSCSI (Block) or through NFS (File). Network Attached Storage (NFS) is a solid, mature, high available, high performing foundation for virtualization environments. I have helped several customers’ last couple of years to make sure that their virtualized environment is stable and high performing. Often when there are (performance) problems people tend to focus on a specific part of the infrastructure like, network or storage.
Always look at it as a complete chain from the user using an application to the location where the data and/or application is stored. Highlights Why use NFS? VMware has supported IP-based storage for almost a decade now. What is NFS? NFS Version used? NFS Protocols and vSphere Solutions. Running Photon OS on vSphere · vmware/photon Wiki. This guide describes how to get started using Photon OS as a virtual machine within VMware vSphere. It provides instructions for downloading Photon OS (as an OVA or ISO file), describes the various installation options, and walks through the steps of installing the Photon OS distribution on vSphere. Once Photon OS is installed, this document highlights how to deploy a containerized application in Docker with a single command. Note: If you want to upgrade an existing Photon 1.0 VM, refer to the instructions in Upgrading to Photon OS 2.0.
About Photon OS Photon OS™ is an open source Linux container host optimized for cloud-native applications, cloud platforms, and VMware infrastructure. Requirements Using Photon OS within VMware vSphere requires the following resources: Note: The setup instructions in this guide use VMware vSphere 6 and the vSphere web client. Deciding Whether to Use OVA or ISO The first step is decide whether to use the OVA or ISO distribution to set up Photon OS. Choose Next. Tom Spirit: vSphere | A VM is showing disk size of 0B. Being given a task to figure out and clean up the mess of a poorly maintained vSphere Infrastructure a while ago, i encountered a very strange problem. They informed me that the Veeam Backup failed for that VM, and the error message was: Virtual disk configuration change detected, resetting CBT failed Details: A general system error occurred: Creating VM snapshotError: A general system error occurred: After I edited the settings of the VM I was suprised to see that the disk sizes were listed as 0 on the menu.
Unfortunately, for my greater torture was that I couldn't find any related KB articles for this problem. One or two issues that I found across the net was users experiences similar problems, but their solutions were entirely different, and very drastic - reboot of the entire ESXi host. I couldn't allow myself to reboot the host as this was a production cluster.
The reason behind this symptom are rogue snapshot of the VM. So how do you solve this problem? First things first: Second: Third: NFS Best Practices – Part 2: Advanced Settings - CormacHogan.com. Following on from part 1 of the NFS Best Practices, part 2 is going to look at tuning from a vSphere perspective. As mentioned, our objective is to update the NFS Best Practice white paper which is now rather dated. There are quite a number of tunable parameters which are available to you when using NFS datastores. Before we drill into these advanced settings in a bit more detail, it is important to understand that the recommended values for some of these settings may (and probably will) vary from storage array vendor to storage array vendor. My objective is to give you a clear and concise explanation of the tunable parameters and allow you to make you own decisions when it comes to tuning the values.
Maximum Number of NFS Mounts per ESXi host By default, the NFS.MaxVolumes value is 8. TCP/IP Heap Size Net.TcpIpHeapSize is the size of the memory (in MB) which is allocated up front by the VMkernel to TCP/IP heap. Heartbeats So what happens if the datastore is not accessible? Locking. VMware Knowledge Base.
Knowledge Base. VMware Troubleshooting: ESX/ESXi Command Line Utilities. For VMware virtual machine management, you have PowerCLI. But for real, technical troubleshooting, VMware's ESX/ESXi command line utilities, available on the hosts themselves, are your best option. This article covers the esxcfg, esxcli, and the vm host tools for troubleshooting an ESX/ESXi environment. The utilities are located on the host system and are run from the host system.
To use these utilities, you'll have to establish a remote SSH connection to the host. See: Essential PowerCLI Cmdlets for Managing VMware Virtual Machines The environment used for this article is a single VMware ESXi host (balvenie), version 4.1 update 3, with a single local datastore. Enabling Remote Access (SSH) to the ESX/ESXi Host Every command in this article is run from the host, therefore you'll have to enable remote SSH access to the host. Open and connect to your vSphere vCenter Server using your vSphere Client.Select a host system. At this point, you might receive a prompt to reboot the ESX/ESXi host. NUMA, VNUMA and CPU Scheduling.

We’ll show you how you can configure ESX(i) to tag packets and how to create virtual switches for your VLANs. Before reading the guide, it’s important to have VLANs configured in your network. More information on how to segment a LAN into VLANs here. First of all, click F2 and access the ESX(i) console to enable VLAN architecture awareness. Select Configure Management Netowrk: Enable VLAN tagging specifying 4095 as value: Specify an IP address for the management network adapter: Define DNS servers: Press Esc and confirm: Now your ESX(i) is VLAN architecture aware. It’s time to launch the vSphere Client. Click Properties: It’s time to remove the VM Network that will be replaced by the VLANs: Create the VLANs with the IDs specified during the (physical) switch configuration clicking on Add: Let’s assign the VLANs to the virtual machines: The final step is to add a second virtual switch using another network adapter. How to prepare for VMware vSphere upgrade? | Settlersoman - A settler in the SDDC world.
When it comes to upgrading the vSphere environment, we have to (or at least should ) prepare for it carefully. I have done many vSphere projects and in order for upgrades to be successful, it's necessary to do some pre-ugrade tasks In this article we discuss the following topics: Why to perform an upgrade? What is the correct vSphere upgrade/update sequence? What should we check before the upgrade of vSphere? Performing vSphere upgrade - main reasons In my opinion, upgrades aren’t necessarily a good or bad idea in general, but you should upgrade only if you can point to three main reasons as follows: End of support for productsSecurityNew features You shouldn’t upgrade because you feel as though you “have to” implement new technology.
End of support As every software, vSphere has a lifecycle, which begins when a specific version is first introduced to us and ends when VMware no longer provides support for that product.

Depuis vSphere 5.0, il est possible d’installer un vCenter sur une appliance virtuelle Linux et ainsi s’affranchir du cout d’une licence Windows, parfois utilisé exclusivement pour ce besoin.
Ça vous oblige à trancher par défaut la question du vCenter physique ou virtuel (voir et à vous accommoder de certaines limitations assez agaçantes (pas compatible avec les modules vCenter tiers + vSphere Update Manager doit quand même être installé sur Windows ? « Allo quoi! » comme dirait l’autre), mais s’affranchir de Windows, ça n’a pas de prix Plus sérieusement, la vCSA (vCenter Server Appliance) a pas mal évolué depuis la version 5.0 pour arriver jusqu’à une 5.5 en Suse Entreprise Linux Server (1 licence SLES incluse avec votre licence vCenter !!!

Details Published: Friday, 22 November 2013 07:57 For a long time it was a hard way to reclaim unused space from thin provisioned disks. The old way includes deleting files, manually fill the free space up with a zeroed vmdk, delete this vmdk, manually start a reclamation process on DataCore and wait until it finishes. Not a very comfortable way to get some space back. The good news is, vSphere 5.5 and DataCore SANsymphony-V 9.0 PSP4 (which was released on 11/11/2013) now fully support the fourth VAAI principle UNMAP. With this new principle you now have the ability to ease the process of reclaiming unused space. Well, UNMAP is not new to vSphere. So it seems worth a bit of testing this new feature along with SANsymphony to see how it works, if there are still some things to keep in mind etc.
The setup is quite common, I use 3 RAID10 sets each containing 4 disks and serving two volumes per RAID set to each DataCore server, so in sum I have 6 disks in each DCS pool. Tangled? How to migrate a vCenter Server database to a new server. Here is a short “how-to” if you want to move your vCenter Server 5.5/6.0 and Update Manager SQL database to a new SQL database server. There is a KB article from VMware covering this topic (KB 7960893 – Moving the VMware vCenter Server 4.x/5.x/6.0.x SQL database). In this blogpost I have added some sidenotes from my experience and you can find some screenshots, too. Preparation: read KB 7960893read this blog post install the new windows server (check compatibility matrix first)install the appropriate SQL server version (take care of the servicepack level,too!) Migration: 1. Stop the following services on your “old” vCenter Database Server: VMware Update ManagerVMware VirtualCenter ServerVMware VirtualCenter Management Webservices 2.
vCenter Server offloads some maintenance tasks to the database. If you move your vCenter database to a new server you have to take care that you recreate these jobs.

La performance sous VMWare : généralité (article 1/4) De nos jours, il est fréquent de réaliser des tests de performance sur des machines virtuelles (VM). Souvent, on réalise une campagne de test de performance sans prendre en compte la spécificité de la virtualisation en considérant que finalement la virtualisation est transparente. Dans certains cas, il est nécessaire d'aller plus loin dans la performance de la virtualisation. Nous allons traiter ce thème en 4 parties: Généralités - Concept OS VMWare La virtualisation des plateformes x86 a commencé dans les années 90.
La virtualisation permet de faire fonctionner plusieurs systèmes d’exploitation sur une même machine. Concrètement, l’ESX attribue une quantité de ressources (CPU, RAM, Espace Disque, Réseau) à chaque système d’exploitation virtualisé en fonction de la configuration qui lui aura été indiquée. Pour bien comprendre ce qu'est VMWare, voici la différence entre un serveur physique et un serveur virtualisé : On observe deux différences principales : Architecture de VMWare Paramétrages : vSphere Documentation Center. Upgrade en vSphere 5 - VMnerds blog. Dans la majeure partie des cas, la mise en place de vSphere 5 va être une mise à jour vers vSphere 5 plutôt qu’une installation depuis zéro. L’upgrade en vSphere 5 va se découper selon les phases suivantes: phase 0: validation des pré-requisphase 1: mise à jour de vCenterphase 2: mise à jour des plugins vCenter (VUM…)phase 3: mise à jour des serveurs ESXiphase 4: mise à jour des VMs (VMtools & Virtual HW) Phase 0: pré-requis Voici, pour rappel, quelques pré-requis pour vSphere 5: Remarque: vCenter 5.0 peut gérer des hôtes ESX/ESXi 3.5, 4.x et 5.0 au sein d’un même cluster.
Phase 1: upgrade vCenter Avant de commencer, sauvegarder la base de données et les certificats de vCenter. Utiliser l’outil Pre-Upgrade Check sur l’hôte vCenter avant la mise à niveau de vCenter Server (environ 30 à 40 secondes/hôte). L’installation propose la mise à niveau de vCenter 4.x (à condition d’être déjà sur un OS 64 bits). Phase 2: upgrade VUM Phase 3: upgrade ESXi Phase 4: upgrade VMs. vSphere Documentation Center.
