The vCenter Server availability could be necessary in most cases and critical for large environment (or where a lot of services depends on it). In small environment, usually, this not so critical, because most of the VMware functions still work also without vCenter Server (for more info see vCenter Server Design: Physical vs Virtual). There are at least four solutions to increase the availability for vCenter Server: use a VM for vCenter Server and use VMware HA use vCenter Server Heartbeat product use a MSCS solution for vCenter (unsupported from vSphere version) use VMware FT […]

From the version VI 3.x the vCenter Server can be deployed or on a physical server or on a virtual machine (both solutions are supported by VMware). In this page pros and cons are analyzed.

Note: VMware has removed the vRAM Entitlements concept and restriction. So this post is no more relevent! Introduced during the official announce of vSphere 5, this news in the vSphere licensing (expecially for the hosts) has been changed (the first rumor of this was mentioned here by Gabrie van Zanten). Not in the priciple (the vRAM is still the allocated vRAM of powered on VM, not the consumed vRAM) but in his value and how are counted (for example there is a max vRAM value of 96 GB for each VM): vSphere edition Previous vRAM […]

Objective 1.5 – Identify vSphere Architecture and Solutions Knowledge See also those similar posts: Objective 1.5 – Identify vSphere Architecture and Solutions and Objective 1.5 – Identify vSphere Architecture and Solutions. Identify available vSphere editions and features (some changes from vSphere 4.x) See the Compare vSphere 5.0 Kits and Compare vSphere 5.0 Editions. Explain ESXi and vCenter Server architectures (similar as vSphere 4.x) See the VMware Sphere Basic guide, the Objective 0.1 – VMware Products and also VMware Web Site. Explain Private/Public/Hybrid cloud concepts See the Objective 0.2 – Cloud Concepts. Determine appropriate vSphere edition based on […]

Objective 1.4 –Secure vCenter Server and ESXi Most of the references are from the vSphere Security Guide, but also the old (from VI 3.x) Managing VMware VirtualCenter Roles and Permissions is still a good reference. See also: Objective 1.4 – Secure vCenter Server and ESXi e Objective 1.4 –Secure vCenter Server and ESXi. Identify common vCenter Server privileges and roles (similar as vSphere 4.x) See: vSphere Security Guide (page 59). Some are available both in ESXi and vCenter Server: No Access: Cannot view or change the assigned object. vSphere Client tabs associated with an object appear without […]

In vSphere 5, for the first time, ESXi has now an integrated firewall. In this way another feature gap between ESXi and ESX has been filled. But this firewall is quite new and different compared to the one from ESX, although the management (at the GUI mode) remain similar of the old one. For more info see: http://vinfrastructure.it/vdesign/esxi-5-firewall/

Objective 1.3 – Plan and Perform Upgrades of vCenter Server and VMware ESXi See also this similar post: Objective 1.3 – Plan and Perform Upgrades of vCenter Server and VMware ESXi and Objective 1.3 – Plan and Perform Upgrades of vCenter Server and VMware ESXi. Identify upgrade requirements for ESXi hosts (similar as vSphere 4.x) See: vSphere Upgrade Guide (page 11) and vSphere Upgrade Guide (page 69). ESXi 5 system requirements are the same for a clean installation: 64 bit CPU, one or more supported NIC, 2098 MB RAM (note that are more than 2 GB), supported storage, […]

See on: http://communities.vmware.com/thread/323082 As most people reading this know, VMware recently announced its vSphere 5 product release.  Although certifications based on vSphere 4 retain their value, we must march onwards; for instance, VCP5 has already been announced.  To this end, today there is the announce of the final opportunity to attempt the VCDX certification based on vSphere 4 designs (this would mean that the VCDX5 certification could be near the corner? maybe in middle 2012?). The city will be Frankfurt, Germany, and the dates will be February 6-10, 2012.  Applications for this session will open on November 14, […]

Objective 1.2 – Install and Configure VMware ESXi See also this similar post: Objective 1.2 – Install and Configure VMware ESXi and Objective 1.2 – Install and Configure VMware ESXi. Perform an interactive installation of ESXi (similar as vSphere 4.x) Interactive installation is quite simple and similar to a generic ESXi 4.x. Seems strange but there is no mention on scripted installation (introduced first time, for ESXi, in version 4.1) in the blueprint, but IMHO you must know them, at least how you can boot from (you can PXE boot the ESXi installer or boot […]

Objective 1.1 – Install and Configure vCenter Server See also this similar post: Objective 1.1 – Install and Configure vCenter Server and Objective 1.1 — Install and Configure vCenter Server. Identify available vCenter Server editions (new in vSphere 5.x) As in vSphere 4.x, the vCenter Server 5 editions are: vCenter Server Foundation: same limits of 4.x (max 3 hosts, no Orchestrator, no Linked mode) vCenter Server Essential: basically a Foundation edition to be used in the Essential and Essential+ bundles vCenter Server Standard: the full edition (with some limits only in the appliance version) For […]

With vSphere 5 now there are two diffent clients GUI oriented to manage vSphere: the traditional vSphere Client (to be installed on a Windows OS) the new client web-oriented: vSphere Web Client. To work correctly this client require a server part (that is already included in the vCSA and must be installed in the Windows version of vCenter). In this page let’s talk about the pros, cons and limits of the vSphere Web Client.
